WOODLAWN HIGH SCHOOL FEASIBILITY STUDY A. INTRODUCTION
Baltimore County Public Schools Introduction | Page 2 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
1. BACKGROUND INFORMATION
Woodlawn High School is located at 1801 Woodlawn Drive, Baltimore, MD. The 317,325 square foot
building consists of three story classroom wings and three-story Auditorium and Gym wing and a two-story
Technology wing.
The original building was constructed in 1961. A classroom addition was constructed in 2002. The
Auditorium was renovated in 2011. A variety of small scale repair and renovation projects have taken
place. These projects include science room renovations (2004), roofing replacement (1991 and 2014),
replacement of gym lockers (1998 and 2008), replacement of gym floor (1999 and 2008) and bleachers
(1999), and phased window replacement (1989 - 2014).
Individual classrooms are smaller than the recommended state square footage of 750 sf. with the average
class size of 30-35 students per class. Woodlawn High School is currently home to an Advanced Path
program. A future vision from Woodlawn administration is for an Early College program.
A team visited the school to evaluate the existing conditions and reviewed the educational spatial need
based on BCPS spatial standards. These standards were used to identify curricular standards and areas of
programmatic deficiencies. As part of this study, we have evaluated the site, architectural, structural,
mechanical, plumbing, and electrical, fire safety, conveying systems and miscellaneous systems such as
telecommunications, security systems, and ADA systems.
Benchmarking the school’s need to the state rated capacity and allowable square footage per student (150
sf per student) indicates the following:
The current enrollment of 1,412 students is below the state rated capacity of 2,129 students.
According to the state formula, using current enrollment of 1,412 students x 150 sf/student =
211,880 of allowable square footage.

As part of the analysis, we have identified needed Educational Enhancements to the existing school to meet
current programmatic requirements as well as the need for additional instructional and support space.
To meet the programmatic needs identified by the school, we project to renovate approximately 25,500 sf
of existing space for ADA upgrades and compliance.
Woodlawn High School should be considered for Limited Systemic renovations and Educational
Enhancements in order to create a 21st century learning environment for its students within the 55 year old
structure.
Major costs associated for Woodlawn High School will be for Limited Renovation Upgrades including
providing air conditioning and sprinklers for the entire school as well as Programmatic Enhancements. Due
to the age of the original building and the lack of major renovations in these areas, new work will disturb
Asbestos Containing Materials.

1. STRUCTURAL SYSTEMS
Introduction
The existing systems that are part of the Structural component category include roof, walls, floors, ceilings,
windows, and doors. These systems and the building configuration have been evaluated with the following
codes:
IBC 2015 and International Existing Building Code 2015
NFPA 101, 2015
Americans with Disabilities Act 2010
Baltimore County Public Schools representatives surveyed the school in September 2015. The following
is a list of structural conditions observed during the survey.
Woodlawn High School was constructed in 1961 and has had two major structural additions, the first in
1969 and the second in 2002. The original building is composed of 6 wings labeled A-F consisting of
adjoining three story classroom wings, a two story technical education wing, a one story cafeteria wing, a
one story music wing and a two story gymnasium wing. The addition in 1969 consists of an auditorium
addition adjoining the gymnasium. The addition built in 2002 consists of a three story classroom wing
south of the original classroom wing. This wing includes a satellite cafeteria and gym. The music and band
rooms are currently located in this addition.
The high school is predominantly a steel framed structure with concrete floors and an insulrock fiber or
gypsum roof. The structure is also composed of various other structural materials and systems including
masonry bearing walls, Dox-Plank, framed concrete slabs, composite steel framed slabs at the 2001 addition
and structural steel trusses at the auditorium addition and original gymnasium.
Roof Structure
The roof deck of the original building consists of a 3” thick insulrock fiber deck. The insulrock fiber deck
is supported by steel joists, wide-flange steel girders, wide-flange steel columns and tube steel columns.
The steel joists are generally spaced at 48” on center maximum and long span steel joists are utilized at the
music wing in area F. The roof of the gymnasium is composed of 3" insulrock deck supported by bulb tees
and wide-flange steel sub-purlins spanning between structural steel trusses. The trusses are supported by
wide-flange steel columns.
The roof deck of the auditorium addition is a 2” thick lightweight concrete fill over a 2" insulating gypsum
roof deck between bulb tee purlins and wide-flange steel sub-purlins. The sub-purlins are supported by
steel trusses and wide-flange steel columns.
The roof framing of the 2002 three story classroom addition consists of 1 1/2" corrugated steel deck
spanning between steel open-web joists or wide-flange steel beams. The joists are at 6'-0" on center
maximum and span between wide-flange steel girders. The framing is supported by wide-flange steel
columns.
Baltimore County Public Schools Limited Renovation Assessment | Page 9 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Second and Third Floor Structure
The second and third floor of the original classroom building is of a 2 1/4” thick concrete slab on corruform
deck. The slab is supported by steel joists at 24” on center maximum and steel wide flange girders. The
girders are supported by steel wide-flange columns. The second floor of the support spaces and the
mechanical mezzanine at the end of the gym are Dox-Plank and Rapidex plank slabs with a 1 7/8" to 2"
thick concrete topping slab supported by steel-wide flange beams, girders, and columns or masonry bearing
walls. The second floor framing at the two story technical education D Wing is constructed the same as the
original classroom wing.
The elevated floor structure at the auditorium is concrete slabs of varying thicknesses supported by masonry
bearing walls or wide-flange steel framing. At one end, the concrete cross-over slab between each side of
the auditorium is a 6" concrete slab supported by steel tee shaped beams and angles which are hung from
the roof structure. The catwalk at the auditorium is composed of a plywood deck supported by steel angles
which are hung from the roof structure.
The second and third floor structure of the 2001 classroom addition is a 3" thick lightweight concrete slab
over 2” composite metal deck. The slab is supported by steel wide-flange beams, steel wide-flange girders
and wide-flange steel columns.
First Floor Structure
The first floor framing of Wings A,B , and parts of C is constructed of varying thicknesses of Dox-Plank
with a 2" thick concrete topping over dirt floored crawlspaces. The Dox-Plank bears on masonry walls. The
floor of the boiler room in Wing C, the first floor of Wings D and F and the Auditorium and 2001 classroom
addition are concrete slabs on grade of thicknesses ranging from 4" at the original construction to 5" at the
auditorium and 2001 additions and 6" at the boiler room.
The main floor of the gymnasium is an elevated slab. The basement slab below is the aforementioned 4”
thick concrete slab on grade. The elevated slab is 8” Dox-Plank with a 2” thick concrete topping. The
Dox-Plank bears on a series of interior masonry bearing walls and steel wide flange beams supported by
steel tube columns. The Dox-Plank is supported by an exterior concrete basement wall at the north, west
and south sides and steel beams and columns at the east side.
Foundation and Walls
The foundation system for the entire building including the additions is spread concrete footings founded
on natural soil. The foundation walls are a mixture of masonry and cast in place concrete which vary in
thickness. The above grade exterior walls are a combination of brick veneer with in general concrete
masonry unit back up or curtain wall. The interior partitions are generally concrete masonry unit walls.
Lintels over punched masonry openings are a mixture of steel channels, steel angles, steel wide flange
shapes, and precast concrete beams. The north wall of the boiler room in Wing C is a concrete counterfort
buttressed wall below grade. The foundation wall on the south side of the boiler room is a cantilevered
concrete retaining wall. The southern half of the 2002 classroom addition has a soil bearing capacity
reduced from 3,000 psf to 2,500psf. The north side of the 2002 addition is buried one story below grade
and supported by a concrete retaining wall.

Site Observations and Existing Conditions
Woodlawn High School was visually surveyed in September 2015. Columbia Engineering, Inc. was able
to access most of the major structural components during the visit. As expected, the accessible structure
corroborates the information contained in the original structural documents made available to the design
team. Below is a list of structural condition issues which were noted during the survey.
Primary and Interior Structure
The primary steel structure appears to be in good condition. It appears to be free from signs of
deterioration and structural distress.
At the crawlspace below the cafeteria and kitchen, there is extensive cracking and spalling of the Dox-
Plank with associated rusting reinforcement.
At the crawlspace of the C Wing adjacent to the boiler room, contrary to the existing drawings, the
floor slab is constructed of Dox-Planks spaced at 40" on center supporting 1"x3" wood slats supporting
a gypsum board form. The concrete slab above is assumed to be at least 2" thick.
There are cracks at the interior corners of the stair tower of B Wing.
In the boiler room, there is evidence of water penetration through the south wall and cantilevered slab.
There are a large number of cracks in the terrazzo floor finish at various locations. These cracks are
likely due to the initial shrinkage of the topping slab on the Dox-Plank.
The majority of the interior masonry walls are in good condition with minor cracks present and not
unusual for a building of this age.
Exterior Structure
The brick veneer is also in good condition for a building of this age. Some cracks in the mortar and
brick veneer were noted. These areas were generally near the walls corners which is likely due to the
lack of control joints in the walls.
The exposed concrete cover of first floor framing at the east side of the gymnasium has spalls and rust
staining.
Cracked and spalled concrete of the columns and floor beam cover is present at the east side of the
technical education D Wing.
The perimeter concrete beams and columns of the bridge between the original classroom C Wing and
D Wing have extensive cracking and spalling. The bearing support angle on the west end of the bridge
is severely rusted.
Baltimore County Public Schools Limited Renovation Assessment | Page 11 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
The concrete covers at the bottoms of the Wing C south columns outside the boiler room have severe
spalls and cracks. There are some cracks in the concrete covers of the first floor framing in the same
area.
The concrete cover of the first floor spandrel beams at the overhang on the south side of the C Wing
has cracks. The concrete slab on grade has settled approximately 3".
The northeast and northwest corners of the cafeteria cantilevered first floor slab has spalled exposing
the rusted reinforcing.
The concrete stairs on the north side of the cafeteria have rust stains and exposed reinforcing.
Recommendations for Exterior Structure
The majority of the deteriorated conditions noted above are due to the age of the building and for
exterior issues, long term exposure to the elements. The issues can be grouped into three main material
categories – masonry, Dox-Plank, and concrete. The masonry issues are mostly cracked or worn
mortar. The Dox-Plank issues, particularly at the first floor of the cafeteria, require a significant amount
repair to the spalled underside of the planks. The concrete issues tend to stem from corrosion of the
internal steel reinforcement. All of these issues are not unusual for a building which is over fifty years
old.
An area of discussion is in the crawlspace of the C Wing. The floor slab was constructed differently
from the original drawings by spacing the Dox-Planks at 40" on center and spanning the clear space
with a concrete slab. This seems to have been done when the building was constructed and has not
adversely affected the use of the building.
Another area of discussion is the bridge between the original classroom Wing C and the tech Ed Wing
D. It is likely that the reinforcing is corroded beyond repair and the bridge should be replaced.
The following items are recommended as part of the renovation:
Repoint cracks in brick veneer where necessary. Also, repoint cracks in the concrete masonry units.
Repair spalls and corroded reinforcement in concrete cover elements by removing loose concrete,
squaring up all edges, cleaning reinforcement of rust, and patching area with a concrete repair
Baltimore County Public Schools Limited Renovation Assessment | Page 12 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
mortar. These areas include the concrete column covers at the gym and Wings C and D, the
concrete slab at the cantilevered cafeteria slab..
Exterior steel lintels that have rusted should be scraped and repainted.
The primary structural concerns associated with renovating the existing building are as follows:
The existing contract drawings indicate that the roof structure was designed to support a uniform
live load of thirty pounds per square foot. Building codes used at the time of design of the existing
building did not require the engineer to consider the effects of drifting snow. The International
Building Code now requires that the designing engineer consider snow drifts at roof elevation
changes and against roof obstructions, such as large mechanical units. The existing building has
areas with roof elevation changes where drifting snow load may exceed the original design live
load. The International Building Code does not require the existing structure to be analyzed and
strengthened unless additional superimposed dead load is placed on the structure or the structural
framing is altered. Consequently, it is important to limit the installation of new roof top mechanical
units to avoid costly structural rehabilitation. If roof top mechanical units are used, it is important
to avoid locating them in areas prone to drifting snow. Locating mechanical units in these areas
could result in the need for widespread reinforcement of the structure.
The 2001 classroom addition will conform to most of the current code requirements.
Relocation of masonry partitions at elevated floors will require an analysis of the floor structure.
It is unlikely that the structure is capable of supporting heavy masonry wall loads without
rehabilitation, so any new partitions should be constructed using light weight materials.
At the time of the design of the original building, codes did not typically require a lateral analysis
for low-rise structures. The addition of new superimposed dead loads on the structure, including
heavy mechanical units, may require that a structural analysis be performed and a new lateral
resisting system may need to be introduced. Also, modifications to the existing lateral resisting
structural elements should be avoided. The interior and exterior masonry walls typically act as the
primary lateral system for this type of building. Therefore, relocating, modifying, or removing
masonry walls could result in the need for a new lateral resisting system. Introducing new lateral
resisting systems into existing buildings is often intrusive and costly.
New floor or roof penetrations will require an analysis of the existing structural system. New steel
frames will need to be installed around large penetrations to support the existing floor or roof deck.
Openings should be limited to the space between main steel members to avoid costly structural
reinforcing of the floor or roof.

Mechanical Systems Existing Conditions
Overview
Woodlawn High School was originally constructed in 1961 (including classroom wing, tech-Ed wing,
cafeteria wing, music wing, and a gymnasium wing), with two additions that followed in 1969
(auditorium addition) and 2002 (3-story classroom wing including a satellite cafeteria). Mechanical
renovations that have occurred include a boiler rooms renovation (2004), science room renovation
(2002), and in 2009 mechanical renovations occurred in the Auditorium and Gymnasium.
Baltimore County Public Schools Limited Renovation Assessment | Page 14 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
The 2004 boiler room renovation included installation of two (2) new 3-pass fire-tube natural gas-fired
boilers and a set of hot water circulation pumps. The central heating hot water is circulated via supply
and return piping running inside pipe tunnels and crawl spaces below the floor leading to the Cafeteria
on the west side and the Gymnasium/Auditorium on the east. A domestic hot water gas-fired vertical
water heater was also installed as part of this renovation.
The 2002 2-story Addition to the building is being served by heating water piped from the main boiler
room. Although there are two new cast iron boilers located in the mechanical room on the second floor
of the new wing that have not been used. The new wing has multiple air-handling units with
heating/cooling coils, and variable air volume (VAV) boxes serving each space.
In 2014, the ventilation air-handling unit serving the 3-story classroom building failed and was replaced
in kind.
Heating
In the 1961 building, the central heating plant comprises the boilers and heating water circulating pumps
located in the boiler room. This heating water is circulated to all school spaces, including the Tech-Ed
wing, Cafeteria, Auditorium and Gymnasium to serve the perimeter radiation heating and various air
handling units, ventilating units, cabinet unit heaters, unit heaters. At this time this heating water plant
additionally serves the 2002 addition, although at present time a project is underway to energize and
re-valve the 2002 boilers as initially designed.
Two (2) natural gas-fired, 400 HP Burnham fire-tube boilers (2004) provide more than adequate heating
capacity for the entire facility. There are primary circulating pumps installed to serve the 1961 3-story
building, Tech-Ed, Gymnasium, and the Cafeteria. Two secondary sets of pumps currently serve the
2002 addition. There are three original vertical expansion tanks with compressed air connections and
an air compressor required for charging. These tanks appear to be in good condition and appear to have
another 10 years of service life. There is a third boiler (cast iron, oil fired) which had been abandoned
after the previous boiler replacement. This boiler is not functioning and is not required for heating
water. It is currently piped into a new hot water system header to serve as a backup for domestic hot
water, although it is simply additional redundancy. This boiler is taking up space in the
boiler/mechanical room, which will be needed as equipment required for air conditioning is added. All
original pumps will need to be replaced as they are well past their life expectancy.
Woodlawn High School is served by multiple heating systems that include: suspended hot water unit
heaters; fin tube radiation along perimeter walls; cabinet unit heaters in toilet room ceilings, wall
hung/recessed cabinet unit heaters in stairwells building entrances and lobbies, and heating coils in
various air handling units, unit ventilators, ventilating, and make up air units. In the 1960 building all
original mechanical equipment has outlived its expected service life and should be replaced. Most of
the original equipment appears to be deteriorated, with bent, clogged fin-tubes and heating coils, noisy
fans, and drives. Although operational, the performance and certainly the control, has deteriorated over
the years affecting the operational efficiency and the occupant comfort.
The piping to circulate the heating water runs in the crawl space serving the ground floor and in ceilings
of the first and second floors, serving each respective floor. Piping to the Cafeteria and Tech-Ed
wing/Gymnasium wing is routed through partially excavated crawl spaces under the building and
below-grade pipe tunnels. Most of the old piping is not insulated as it has been partially removed in an
asbestos abatement.

Woodlawn High School Feasibility Study
Recommendations for Heating
The perimeter fin-tube radiator heating system should be demolished and replaced with an
entire new means of heating each space. All mechanical equipment including suspended unit
heaters, recessed and wall mounted unit heaters, fans, coils, air handlers, etc. should be replaced
as they are over 55 years old and have well outlived their expected service life. As most of the
mechanical equipment is being
A portion of the piping to the first floor science labs has been replaced during the 2004
renovation. All piping, insulation, valves, strainers, gauges, and all appurtenances will need to
be replaced in the 1961 building. Only the heating water piping serving the 2002 addition can
be retained as it has a separate chilled water system.
Cooling
The 1961 3-story building and the Tech Ed annex has no central cooling. The general classrooms and
common areas such as the Cafeteria only have heating and ventilating, no cooling. The 2009 systemic
renovation added an air cooled chiller and air handing units to provide heating, ventilating, and air
conditioning into the Gymnasium and Auditorium.
Several areas such as the Media Center, computer classrooms, faculty lounges, and the majority of
offices are cooled by window air conditioners or packaged through-the-wall air conditioners. The
Media Center workroom/office as well as a computer room are served by Trane system (2001), with a
ceiling hung split system fan-coil and a roof mounted condensing unit. These units are in fair condition.
One data equipment room is served by a Sanyo Pac-1 split system (2008), with a roof mounted
condensing unit and a wall mounted indoor fan coil unit.
A partial renovation to the Health suite in 1984 added a cooling via a ducted ceiling recessed fan coil
unit with DX cooling and roof mounted condensing unit. This unit is at its expected life expectancy.
First floor Administration areas such as the main office, assistant principals’ offices, accounts, guidance
offices, are served by window air conditioners. The faculty room is served by a window air conditioner.
The second floor Principal’s office, Dean’s office, Guidance and Counselors offices all are served by
window air conditioners. These units are in good to poor condition dependent on the age of install.
The 2002 addition is centrally cooled via a split (with remote condenser) packaged central water chiller,
located in the second floor mechanical room and roof respectively. The chilled water is circulated to
the air handling units located in the addition’s mechanical room. Electrical and data equipment are
served by multiple DX split system units with remote condensing units on the roof and indoor fan coil
cassettes suspended in the ceiling.
Recommendations
In the 1961 building all original mechanical equipment has outlived its expected service life
and should be replaced. This mechanical equipment needed for heat has deteriorated and is
non-efficient energy wise. Additionally, noisy antiquated window air conditioners as well as
faulty, mal-functioning pneumatic temperature controls need to be replaced. The
recommendation is to provide a new dual temperature (2-pipe) system, including seasonal
central chilled water, for the entire original school building. This will replace the perimeter
heating, decoupled ventilation system and the window air conditioners with an entirely new
engineered system. Not only will this provide will better management of the heating/cooling
system, but achieve adequate controlled ventilation to meet the current Indoor Air Quality

Woodlawn High School Feasibility Study
(IAQ) standards recommended by ASHRAE. This includes the Cafeteria and the Tech-Ed
Wing that is presently only heated and ventilated. It is proposed a new packaged air cooled
chiller be installed external to the building, in order to supplement the smaller chiller added for
the gymnasium and the auditorium. During the schematic phase of the design project,
engineering consultants will run HVAC “loads” and analyze the cooling needs for the building.
New dual temperature piping, pipe insulation, valves, hangers, and appurtenances will be
required. New terminal equipment will be required in all spaces, including the classrooms.
In the 2002 addition, the mechanical equipment is within expected life service expectancy and
is in good condition. No recommended changes are itemized in this part of the building.
Ventilation
Outdoor air is supplied into occupied classrooms in the 1961 building, through an air handling unit in
the boiler room, which transports the air via ducts into each classroom using corridor side high wall
grilles. This air handling unit was replaced in kind, after the original 1961 unit failed. This ventilation
air is heated only at present. There is no means to dehumidify the incoming outside air to remove
humidity. The air handling unit is a constant volume unit, serving each space with air whether or not
the rooms are occupied. A set of duct risers prevents over pressurization by relieving the air to the
outside through roof mounted ventilators.
Recommendations
Although the air handler was recently replaced, it will need to be evaluated with the new HVAC
system designed. The present air handler at this time has no means to cool/dehumidify
incoming outside air which is critically important. All capacity (cfm), insulation, valves, etc.
will need to be replaced. Ductwork will need to be resized and reinsulated. This will be
investigated as part of the upcoming design contract.
Exhaust systems
All of the toilets, lockers, shower rooms, and the equipment rooms have exhaust fans or are connected
to common ducted exhaust systems in the 1961 building. The systems are presently operational, but
some of the exhaust grilles have clogged over and most of the fans and motors have outlived their
expected service life. Current Code requirements have changed from the initial year of design, and it
is to be expected that the toilet room ventilation and general room air changes will need to be increased.
Some of the science labs, prep rooms, and adjacent storage rooms do not have separate exhaust systems.
The 2002 renovated science rooms have been provided with ceiling exhaust grilles that are ducted to
the outside.
The kitchen has a large double island hood arrangement, which is in use as this space operates as full
cooking kitchen. The installed hood does not meet current code. A large two-speed exhaust fan serving
the kitchen hood is located above in the penthouse of the roof, along with other exhaust fans for the
dishwashing area and staff toilets. The kitchen utilizes steamers and ovens.
Recommendations
All exhaust systems for toilet rooms, storage rooms need to be evaluated for current code-
mandated air changes per hour. The existing fans, ductwork, dampers etc. should be replaced
as they have outlived their service life. The new exhaust fans and ductwork may need to be
Baltimore County Public Schools Limited Renovation Assessment | Page 17 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
resized. New systems will be provided with DDC controls to enable control during
occupied/unoccupied hours.
The current kitchen hood is functional and in fair condition, although it does not meet industry
expected design standards. It is recommended to replace the hood, the exhaust fan, and install
a new make-up air unit to serve the kitchen.
Specific Area Analysis
Administration Area
The Administration offices along the exterior walls have perimeter heating and window air
conditioners. The internal spaces as the main office and workrooms are ventilated and heated by the
central ducted system. The interior offices become overheated in winter and stuffy during the spring
and summer, as there are no windows to open.
Recommendations for Administration Area
This entire area should be evaluated for a central heating, cooling, and ventilating system.
There are many options to evaluate including Variable Refrigerant Flow (VRF) with Dedicated
Outdoor Air System (DOAS).
Auditorium
The auditorium HVAC system was replaced in 2009, and is in good condition.
Recommendations for Auditorium
This space should not be replaced.
Gymnasium
The gymnasium HVAC system was replaced in 2009, and is in good condition.
Recommendations for Gymnasium
This space should not be replaced.
Cafeteria
The cafeteria is served by multiple floor mounted heating only unit ventilators. Outdoor air is being
brought in from the roof to the unit ventilators through fresh air intakes. Air is relieved through roof
relief openings with dampers and louvered penthouses.
Recommendations for Cafeteria
All unit ventilators should be removed along with all heating water piping and pneumatic
controls. The area should then be served by an air handling unit (possible roof top location).
The supply and return ducts should be run above the ceiling to distribute conditioned (heated,
cooled, filtered, dehumidified) air into the space utilizing ceiling mounted diffusers. The new
space thermostat and all mechanical controls should be connected to the new building DDC
automatic temperature control system.
General Classrooms
All 1961 classrooms including some of the specialty classrooms such as Cosmetology and Life Studies
have existing hot water fin tube radiators installed on the exterior walls. Although this heating system
is still functional, the temperature control does not work. Occupant comfort is compromised by non-
Baltimore County Public Schools Limited Renovation Assessment | Page 18 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
distributed heating, only along the wall. These rooms also tend to overheat and the occupants leave the
windows open to compensate. The classroom ventilation system as stated previously is a central air
handling unit located in the boiler room.
Technology Wing
The HVAC systems in the two-story wing are comprised of perimeter radiation heating in the upper
level classrooms and ducted ventilation air handling unit ventilation in the lower former shop spaces.
The former shops also have suspended hot water unit heaters. The former wood working shop has a
dust extraction system. Storage and other support spaces have exhaust systems. One of the classrooms,
used as a computer classroom, has a window air conditioner. Another classroom has had a unit
ventilator installed.
Automatic Temperature Controls
The 1961 building has pneumatic automatic temperature controls. The system is comprised of an air
compressor/receiver unit and refrigerated air dryer that are located in the boiler room, and several
control boxes in mechanical rooms around the building. Although the system is operational, several
pneumatic actuators are disconnected and no longer in use. Some of the room thermostats have leaky
connections, evidenced by hissing sounds of escaping air. The boiler room controls, as well as the
gymnasium/auditorium controls have been converted to direct digital controls (DDC). It is
recommended to replace all pneumatic controls with fully integrated DDC system. This will allow
remote access to building management systems via a local link as well as over the internet. The DDC
system with graphic interface are easier to operate and can be specified with self-diagnostic capability
for troubleshooting. As it is proposed that the majority of the mechanical equipment needs to be
replaced, the replacement of DDC controls and new actuators and valves will be very beneficial. The
controls added in 2009, are in good condition and may remain.
The 2002 building has entire DDC controls, which have been interfaced into the existing building’s
pneumatic system. No additional work is required in this addition.
Mechanical Systems Proposed Modifications
The objective of BCPS is to provide cooling to all portions of Woodlawn High School. At least three
options will be analyzed by the design consultant during the schematic design phase. These systems
will be analyzed for feasibility of providing code compliant cooling and ventilation capabilities. Option
1 is a Fan Coil Unit and Dedicated Outside Air System, Option 2 is a Variable Refrigerant Flow and
Dedicated Outside Air System, and Option 3 is a Variable Air Volume Rooftop Air Handling Units.
Each of the options developed concentrates on the classroom spaces due to ventilation requirements.
Option 1
Fan Coil Unit and Dedicated Outside Air System (General Discussion)
This system includes adding a chiller to the central plant of the 1961 building to produce chilled water.
A dual temperature fan coil unit would be installed in each classroom, in lieu of the perimeter fin tube
radiators. Ventilation would be provided by a packaged self-contained air-cooled Dedicated Outside
Air System (DOAS) with hydronic heating. There are many benefits to decouple the outside air in its
own system.
Heating Water Plant: The existing heating water plant has sufficient capacity to provide heat for
the terminal equipment. A heating water plant boiler controller would be installed to interface the
Baltimore County Public Schools Limited Renovation Assessment | Page 19 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
heating water plant with the Building Automation System. Heating water pumps would be added
to create a primary-secondary pumping arrangement.
Chilled Water Plant: An air-cooled chiller would be installed to produce chilled water for
distribution to terminal equipment throughout the school. The chiller would need an engineered
acoustical enclosure to minimize noise proliferation and to protect the chiller from vandalism.
Within the boiler room chilled water pumps would be installed for a primary-secondary pumping
arrangement.
Hydronic Distribution: Not only is the existing piping and insulation in poor condition it is also too
small to accommodate the chilled water flow rate required by the terminal equipment. The
distribution pumps would be replaced to create a primary-secondary pumping arrangement.
Fan Coil Unit: The terminal fan coil units would have a dual temperature coil. The fan coil units
would receive chilled or heated water from the central physical plant and associated distribution
piping. The fan coil units will not provide ventilation to the rooms. They will be sized to
accommodate the room envelope and occupant load only (no latent load).
Dedicated Outside Air System: The Dedicated Outside Air System (DOAS) provides code
compliant ventilation air flow for each room while simultaneously exhausting all of the rooms to
prevent over-pressurization in a code compliant manner. The DOAS equipment will be packaged
stand-alone units connected to the hydronic system for heating only. The DOAS will be equipped
with a hot gas reheat coil. The hot gas reheat coil allows the unit to reheat the chilled, dehumidified
air to a room neutral temperature which will help to prevent overcooling of the spaces and also
complies with building codes for energy recovery. The DOAS equipment will be connected to the
dual temperature hydronic piping network, but will be configured to use only heating water.
Remaining Spaces: The remaining spaces will be conditioned using hydronic Air Handling Units
(AHUs) or Roof Top Air Handling Units (RTUs) connected to the central plant. Spaces requiring
12 month cooling will include also include a DX coil. The AHUs /RTUs will be variable volume
units with the capability of modulating supply air flow as needed to condition the spaces.
Option 2
VRF and Dedicated Outside Air System
This system replaces fin tube radiators in each classroom with a refrigerant based fan coil unit, and
ventilates with a DOAS system. Some perimeter heating system may be provided as supplemental heat.
Heating Water Plant: The existing heating water plant has sufficient capacity to provide heat for
the terminal equipment. A heating water plant boiler controller would be installed to interface the
heating water plant with the Building Automation System. Heating water pumps would be added
to create a primary-secondary pumping arrangement.
Hydronic Distribution: The existing piping and insulation is in poor condition and would be
replaced to serve the terminal equipment. The distribution pumps would be replaced to create a
primary-secondary pumping arrangement.
Chilled Water Plant: This solution does not include a central chilled water plant.
VRF: The Variable Refrigerant Flow (VRF) system is a way of providing cooling to terminal spaces
while eliminating the need for a major hydronic distribution system. The VRF system uses multiple
pieces of terminal equipment connected to a refrigerant piping network and a single outdoor
compressor unit. The refrigeration circuit modulates as needed to increase efficiency and optimize
thermal comfort and can utilize a heat exchanger to minimize energy usage.
Baltimore County Public Schools Limited Renovation Assessment | Page 20 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Dedicated Outside Air System: DOAS provides code compliant ventilation air flow for each room
while simultaneously exhausting all of the rooms to prevent over-pressurization in a code compliant
manner. The DOAS equipment will be packaged stand-alone units connected to the hydronic
system for heating. The DOAS can be equipped with a hot gas reheat coil. The hot gas reheat coil
allows the unit to reheat the chilled, dehumidified air to a room neutral temperature which will help
to prevent overcooling of the spaces and also complies with building codes for energy recovery.
Heating would be accomplished using the hydronic heating water system.
Supplemental Heating: To supplement the heating capabilities of the VRF system, a perimeter
heating water finned tube system would be installed. This system would be a backup system to the
VRF for normal operation and could also be used to implement a heating season setback schedule
that would be unfeasible to achieve with VRF alone.
Remaining Spaces: The remaining spaces will be conditioned using direct expansion Air Handling
Units (AHUs) with hydronic heating. The AHUs will be variable volume units with the capability
of modulating supply air flow as needed to condition the spaces. Hot water reheat will be provided
for spaces on an as-needed basis.
Option 3
Variable Air Volume System
This system removes the unit ventilators from all of the classrooms and uses Variable Air Volume
(VAV) Rooftop Air Handling Units (RTU) to supply the room with conditioned air and ventilation.
With this system the central chilled plant is eliminated. The units use direct expansion (DX) cooling
and hot water heating. The hydronic piping infrastructure would be replaced.
Heating Water Plant: The existing heating water plant has sufficient capacity to provide heat for
the terminal equipment. A heating water plant boiler controller would be installed to interface the
heating water plant with the Building Automation System. Heating water pumps would be added
to create a primary-secondary pumping arrangement.
Hydronic Distribution: The existing piping and insulation is in poor condition and would be
replaced to serve the terminal equipment. The distribution pumps would be replaced to create a
primary-secondary pumping arrangement.
Chilled Water Plant: This solution does not include a central chilled water plant.
VAV ACU: The VAV ACUs would be installed on the roof. Ductwork would be routed to the
ceiling spaces of the classroom wings. The quantity of ACUs would be determined by the
maximum ductwork sizes that can be installed in the corridor ceilings. Cooling capabilities for the
units would come from either a remote or integral condensing unit depending on whether the indoor
or rooftop option was selected. The heat source for these units would be a hydronic heating water
coil connected to the central heating water plant.
VAV Boxes: Parallel fan-powered VAV boxes would be installed in the classrooms to control the
air volume and temperature as needed for each room. The VAV boxes would be provided with
reheat capability in order to provide sufficient zone temperature control.
Remaining Spaces: The remaining spaces will be conditioned using direct expansion Rooftop Units
(RTUs) with hydronic heating. The RTUs will be variable volume units with the capability of
modulating supply air flow as needed to condition the spaces. Hot water reheat will be provided
for spaces on an as-needed basis.

Woodlawn High School Feasibility Study
Proposed System Analysis
To evaluate each of the systems, each option will be analyzed for the criteria of constructability, system
performance, and long term operation.
Option 1
Fan Coil Unit and Dedicated Outside Air System
Constructability: The fan coil units will generally be installed in the same location as the existing
unit ventilators. Dual temperature hydronic piping will follow the existing pipe path in the corridor
ceilings. The only feasible location for the DOAS units is on the roof. The ductwork distribution
system would be located adjacent to the deck in the classroom spaces visible to the occupants. With
the multi-floor construction of this building, ductwork routing would have to pass through the third
floor to the second floor, to the first floor. This creates a need to phase the construction vertically
in some cases. The project would have to be phased with the concentration on the central plant.
The chiller and the central plant modifications would need to be near completion prior to initiating
operation of any of the hydronic cooling equipment. Once cooling is available then individual
DOAS units and fan coil units could be brought online.
Performance: The DOAS unit would be configured to assist with the room cooling requirement, in
order to optimize selections for FCUs. With the DOAS system assisting with the cooling
capabilities of the room, the thermal capacity of the fan coil units would be minimized. This system
will be highly reliable and robust with redundant systems for heating, cooling and hydronic
distribution. The fan coil units are reliable with low failure rates. The DOAS units have a potential
of losing cooling capability since each unit relies on a compressor. But since the fan coil units are
using the chilled water system, a loss of a DOAS unit would not result in a system failure. If the
central chiller plant fails, the DOAS unit will provide some cooling capability allowing the school
to continue operations.
Operation: This system will require filter changes at the terminal equipment. Fan coil units will be
floor mounted for easy access and the DOAS units would be on the roof easily accessible for
maintenance. School operations staff would have to periodically maintain the boilers and chiller
and central plant equipment with major repairs requiring a system specialist. Strainers and belts at
terminal equipment would have to be periodically maintained by school operations staff.
Option 2
VRF and Dedicated Outside Air System
Constructability: Indoor units will be floor mounted similar to fan coil units, with outdoor units
being roof mounted. Refrigerant lines would be routed above the ceiling with pipe drops occurring
at the perimeter walls near the terminal units. The DOAS ductwork would be located adjacent to
the deck in the classroom spaces visible to the occupants. With the multi-floor construction of this
building, ductwork routing would have to pass through the second floor to the first floor. This
creates a need to phase the construction vertically in some cases. This system offers the greatest
flexibility of the proposed options for phased construction. Without a dependency on the central
chilled water plant, any portion of the school could begin construction at any time. Phasing would
not be dependent on the HVAC system, all HVAC systems could be modified to accommodate
building operations and phasing.
Baltimore County Public Schools Limited Renovation Assessment | Page 22 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Performance: With the ability to make each classroom a separate zone, this system offers individual
room occupant comfort as the system can provide independent means of heating and cooling to all
spaces. Locations would have to be established for branch selector boxes. The DOAS system would
be sized to assist with room heating and cooling capacity. Finned tube would be used to maintain
space temperature during unoccupied heating and to recover the building after temperature setback
operation, and to provide backup heating should there be a VRF system failure in heating. BCPS
has installed many VRF systems in administration/guidance/health suites to much success in
occupant comfort.
Operation: This system will require filter changes at the terminal equipment. Fan coil units will be
floor mounted for easy access and the DOAS units would be on the roof easily accessible for
maintenance. A VRF specialist and DOAS specialist would be needed for performing maintenance
of the outdoor units. School operations staff would have to periodically maintain the boilers and
central plant equipment with major repairs requiring a system specialist.
Option 3
Variable Air Volume System
Constructability: The quantity of Variable Air Volume boxes would be dictated by the maximum
ductwork size that could be installed. Duct work mains for the air handling units would be run
through the classrooms adjacent to the deck visible to the occupants. The VAV boxes would be
tapped off of the mains with the piping package also visible to the occupants. Linear slot diffusers
would be installed near the perimeter wall to minimize temperature stratification across the room.
With the multi-floor construction of this building, ductwork routing would have to pass through
the second floor to the first floor. This creates a need to phase the construction vertically in some
cases. The ductwork for this option will be considerably larger than the other options. This system
would have to be phased with a focus on the Rooftop Units. Only the rooms being served by an air
handling unit would need to be disturbed.
Performance: With the ability to serve each room with a fan powered VAV box, this system offers
individual room occupant comfort. The fan powered boxes for each room have a potential of
creating fan noise in the space since there is no ceiling to conceal the equipment.
Operation: This system will require filter changes at the terminal equipment. VAV boxes will be
mounted in the classrooms adjacent to the deck which limits accessibility for maintenance. The
Rooftop Units would be on the roof easily accessible for maintenance. School operations staff
would have to periodically maintain the boilers and central plant equipment with major repairs
requiring a system specialist. Any repairs to the pressurized refrigerant of the Rooftop Units would
have to be performed by a specialist.
Life Cycle Cost
During the schematic design phase, a life cycle analysis will be performed by the engineering consultant
to evaluate the systems above. These results will be discussed with Baltimore County Public Schools
in great detail. The life cycle cost for Woodlawn High School will be calculated with the aid of
computer load computing software. Based on a combination of the analysis of the design criteria and
the life cycle cost, recent results often indicate that Option 1: Fan Coil Unit with DOAS has the best
life cycle returns. This solution is a robust system that has a combination of a central plant concept as
well as a distributed concept. This hybrid system does not allow failure of a single piece of equipment
to disrupt school operation. The engineering consultant will also look at utilizing a VRF system for the
administration/guidance/health areas.

Woodlawn High School Feasibility Study
3. PLUMBING SYSTEMS
Criteria for Feasibility Study
The existing mechanical systems have been evaluated for safety, code compliance, life expectancy, and
capacity for expansion in accordance with the listed codes and standards.
National Standard Plumbing Code (NSPC), 2015
Maryland State Department of Education Standards
Baltimore County Public Schools Facility Standards
Baltimore County Health Department Standards
Existing System: The domestic hot water heater was replaced in the 2004 Boiler room systemic. The
remainder of the plumbing system, including the piping, fixtures, sanitary and vent lines is original to the
building. As the pipes have aged, discolored drinking water has been identified if the pipes have not been
properly flushed.
Recommendations: All domestic hot and cold water piping and associated insulation in the 1960 building
should be replaced. These systems have exceeded their life expectancy and also run in locations where the
ductwork and piping distribution systems of the proposed HVAC systems have been identified. Fixture
modifications would be performed on an as-needed basis to accommodate an ADA bathroom renovation.
Water fountains will be replaced with ADA compliant water coolers requiring associated power, on an as
needed basis. The sanitary system will not be replaced in its entirety. Sanitary will only be disturbed as
needed to accommodate restroom renovations. All toilet plumbing fixtures will be replaced and will comply
with ADA requirements.
4. ELECTRICAL SYSTEMS
General Information
Most of the lighting fixtures, power receptacles, panel boards, feeders, and branch circuit wiring in the
original 3-story building were constructed in 1961. The lighting fixtures seem to have been retrofitted with
electronic ballasts and T8 lamps approximately 10 years ago. The exact date of this retrofit work could not
be determined. During the construction of the 2002 Addition, electrical service for the entire school was
upgraded. Presently, the building has 4000 amp, 480Y/277 volt, 3-phase, 4-wire service, but BGE electrical
service to the school was not upgraded and is still rated for 1200 amp. Entire electrical distribution system
(feeders, transformers, branch circuit wiring, etc.) for the original building is more than 50 years old, as
construction in 1961. The fire alarm system for the entire building was also upgraded around the same
time. The renovation of the Auditorium and Gymnasium as well as partial renovation of other areas was
completed in 2011.
Main Electrical Service (Normal Power)
Main electrical service for the school was upgraded in 2002 and is 4000 amp, 480Y/277 volt, 3-phase, 4-
wire system. Peak demand load history for the past few years was collected from BGE. Peak demand
history indicates that the highest peak demand recorded for the service was 1435 KW. This is
approximately 1920 amp on a 480 volt, 3-phase, 4-wrire system with a 90% power factor. This means that
the switchboard can accommodate substantial future loads. The existing switchboard is only 6 years old
and in very good condition.
The 4000 amp switchgear does not have a main disconnect switch. There are only three (3) – 1600 amp
circuit breakers with each circuit breaker serving a 1600 amp, 480/277V switchboard. There is only one
Baltimore County Public Schools Limited Renovation Assessment | Page 24 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
space in the 4000 amp switchgear to accommodate new 1600 amp circuit breaker. NEC Article 230.71(A)
allows maximum of six (6) disconnecting means in any switchgear without main disconnect means in the
switchgear.
The service conductors from BGE to the switchgear consist of only four (4) sets of 500 Kcmil (aluminum)
in 4-way 4 inch duct bank. It appears that in 2002, although the service equipment was upgraded, the
service conductors and the duct bank for the electrical service were not upgraded.
Recommendations for Main Electrical Service
The switchgear is only 6 years old and it is not recommended that it be replaced. It is recommended
that a new 4000 amp main circuit breaker section with BGE CT cabinet and metering be added in
the other room (near the existing electrical room) of the building and a new 12 way -4” duct bank
be provided from BGE transformer to the new 4000 amp main circuit breaker. Then the existing
4000 amp switchgear be back fed from the new main circuit breaker by providing 4000 amp feeder
wiring and raceways. Existing 1600 amp BGE service to the existing 4000 amp switchgear shall
be disconnected and removed.
Stand-by Emergency Power (Generator) and Distribution System
There is no emergency power generator in the building. All emergency lighting fixtures and exit lights
have individual emergency battery packs, which are not reliable when needed in emergency.
NEC requires a dedicated automatic transfer switch (ATS) to serve life safety loads such as emergency
lighting, exit lights, fire alarm, etc. all other miscellaneous loads such as mechanical loads, security system,
telecommunication, and others shall be served via another dedicated ATS.
Recommendations for Stand-by Emergency Power (Generator) and Distribution System
It is recommended that a new 350KW, 480Y/277 volt, 3-phase, 4-wrire, diesel engine emergency
generator to be provided. New automatic transfer switches, 480Y/277 volt and 208Y/120 volt panel
boards and transformers, and feeders shall be added to meet the NEC requirements. All life safety
loads shall be separated from the existing panels and shall be connected to the dedicated panel for
life safety loads. All mechanical loads, telecommunication loads shall be connected to the other
emergency panels. It is recommended that the following equipment shall be connected on the
emergency generator with the approval of BCPS.
Life safety building loads such as night lights, exit lights and exterior lighting in the path of egress
(mostly on the exit doors from the building), fire alarm system, boilers, hot water pumps, circulating
pumps, ATC panels, selected telecommunication equipment, selected refrigerator loads in the
kitchen, and any other loads desired by BCPS
General Lighting
All lighting throughout the entire school utilizes T-8 lamps and electronic ballasts. Most of the lighting in
the 2002 Addition building is 2x4 recessed lighting fixtures that is in good condition. General classrooms
and offices have 2x4 acrylic lens fixtures. Computer rooms have 2x4 parabolic lens fixtures. Most of the
lighting in the original 1961 school building has suspended type fluorescent lighting fixtures which utilize
Baltimore County Public Schools Limited Renovation Assessment | Page 25 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
T-8 lamps and electronic ballasts. Old fixtures were retrofitted with new ballasts and T8 lamps
approximately 10 years ago.
Some spaces have incandescent fixtures, such as in the boiler room, crawl space and storage spaces, Some
classrooms and laboratories were renovated in 2004 which old suspended fixtures in these areas were
replaced with 2x4 recessed fluorescent lighting fixtures. None of the spaces in the school such as
classrooms, science labs, offices, restrooms, have been provided with occupancy sensors.
Exterior Lighting at the main entrance to the building is in poor condition and does not meet the BCPS
standards. The parking lot lighting seems inadequate for security purposes.
Auditorium and Gymnasium lighting were upgraded in 2009.
Recommendations for General Lighting
It is recommended that all lighting in the original 1961 and 1964 school buildings shall be replaced
with new LED lighting fixtures. It is further recommended that occupancy sensors with dual
technology be installed in most areas (such as classrooms, offices, storage spaces, restrooms, and
other areas). This feature meets ASHRAE 90.1 requirements that are required for LEED
certification. The lighting in the 2002 Addition building can remain and will be upgraded or
replaced where required. All classrooms, offices, labs, toilet rooms, etc. in the entire building
should be proved with occupancy sensors.
Due to increased security demands, it is recommended that new exterior lighting be provided. New
surface mounted fixtures and parking lot lighting with the correct color spectrum for security
purposed should be provided.
Emergency Lighting
Emergency lighting consists of two types of fixtures: battery-packed wall mounted twin lamp fixtures and
exit signs. Exit lights operate continuously, but batter packed lighting fixtures come on only in the event
of loss of normal power in the area. Presently, all emergency lighting fixtures and exit signs use emergency
battery packs and are costly to maintain. The battery packs may not work when needed in case of
emergencies, if not maintained on regular basis. It was also observed that almost every room, including the
smallest offices had been proved with battery-pack emergency lighting fixtures.
Recommendations for Emergency Lighting
It is recommended that all the battery-pack emergency lighting fixtures be removed and selected
regular fixtures in the path of egress in each space be connected to emergency power circuits.
Similarly, all exit lights with battery packs should be replaced with new LED-type exit lights that
should also be circuited to the emergency power distribution system.
General Receptacles
Most of the classrooms have only two receptacles on the front wall and two receptacles on the back wall.
Very few classrooms were observed to have receptacles on the common walls to the corridor and the
exterior walls. Most of the receptacles in the science rooms are not GFCI type. Current BCPS Standards
require that all receptacles be ground fault protected. Most of the science rooms had emergency shut off
switches for turning off the power to all student stations. However, there were no emergency shut-offs
Baltimore County Public Schools Limited Renovation Assessment | Page 26 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
observed for the lab gas as required by State regulations. Corridors do not have enough receptacles. Some
corridors have none at all. The cleaning staff reportedly uses extension cords from classroom receptacles
to operate vacuum cleaners, floor polishing equipment, etc.
Some of the receptacles in the original 1961 building were randomly opened to check the condition of
wiring inside. None of the receptacles had any grounding conductors. Receptacle outlet boxes were not
grounded. Most of these receptacles are not grounded. An open ground condition is dangerous and could
pose a shock hazard to students and staff.
Recommendations for General Receptacles
It is recommended that all receptacles in the classrooms should be supplemented by adding more
receptacles in each classroom to conform to today’s demands. All lab receptacles should be
replaced with GFCI receptacles. It is recommended that new manual reset type emergency shut
offs be provided in all the science classrooms to simultaneously cut off the gas as electric power to
all lab stations.
It is recommended that more general purpose receptacles be added in the corridors.
It is recommended that all branch circuit wiring for all receptacles, lighting and other branch circuits
(except the receptacles for computer/data wiring) be replaced with new wiring with proper green
conductors for equipment grounding.
Computer Receptacles
Power receptacles for data wiring that were installed throughout the building in 2002/2004 are in good
condition.
Recommendations for Computer Receptacles
It is recommended that additional receptacles should be added in the new computer rooms/labs,
classrooms, and other academic areas to meet State requirements for all renovated areas and new
additions.
Panel Boards and Feeders
Most of the panel boards and feeder wiring in the new 2002 Addition are manufactured by Square D and
in good condition.
All panel boards and feeders in the original 1961 building are original equipment back from 1961. Most of
these panel boards are manufacture by General Electric (GE). From the outside, most of the panelboards
appear to be in fair condition, but when opened randomly to verify the condition of panels, feeders, and
branch circuit wiring, it was observed that most of these panels do not have any green (equipment)
grounding conductors installed with the feeders, and there is no grounding bus inside the panels. This is
true for all except for the panels installed in 2002/2004 for computer wiring upgrades.
Recommendations for Panel Boards and Feeders
It is recommended that all panels and the feeders in the original 1961 building be replaced with
new panel boards with grounding buses, and new feeders with grounding conductors for the safety
of the students and staff.
Baltimore County Public Schools Limited Renovation Assessment | Page 27 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Branch Circuit Wiring
Most of the branch circuit wiring in the new 2002 addition building has green grounding conductors and in
good condition. Similarly, the branch circuit wiring the computer systems installed in 2002/2004 have
green ground conductors and in good condition.
In the original 1961 building, very few branch circuits have green (equipment) ground conductors, It
appears that these few grounding conductors were added within the last few years with MC cables,
whenever any new branch circuit wiring was added. Receptacles (checked randomly) were found to have
open ground, meaning even the boxes are not grounded.
Recommendations for Branch Circuit Wiring
It is recommended that all of the branch circuit wiring in the original 1961 building be replaced
with new branch circuit wiring with green equipment grounding conductors for a grounded system
for the safety and protection of students and staff.
Fire Alarm System
The entire fire alarm system in the building was upgraded in 2002 and is in good condition. The existing
fire alarm system is a combination of voice evacuation system (speakers and strobes) in the assembly areas
of the building such as the Cafeteria, Gymnasium and Auditorium. The rest of the building has horns and
strobes.
Recommendations for Fire Alarm System
Any area being renovated and any new addition provided will require relocation of fire alarm
devices and/or additional horns and strobes to meet the National Fire Code requirements. New fire
alarm system devices (speakers and strobes) will be provided in the auditorium and gymnasium
areas, currently being renovated.
New fire alarm system devises (duct smoke detectors) will be provided in all new mechanical units.
Technology
A technology upgrade shall include modification to MDF and IDF rooms as well as dedicated cooling and
emergency power.
Intercom/PA/Master Clock Systems
The Intercom (Telecenter 21) can remain but the original wiring and speaker/phones should be replaced.
The unit should be relocated out of the main office area and the enclosure removed to give more space to
the office. A cover will need to be installed for the existing wiring from the new building. School has had
a new Master Clock (Sapling) system installed in 2014. Local PA Systems - Gymnasium needs to be
replaced. Auditorium PA system may require the modification. Cafeteria PA was upgraded in 2015.
5. FIRE SAFETY SYSTEMS
Introduction
Criteria for Feasibility Study
The existing fire suppression systems have been evaluated for safety, code compliance, life expectancy,
and capacity for expansion in accordance with the listed codes and standards.
Baltimore County Public Schools Limited Renovation Assessment | Page 28 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
National Fire Protection Association (NFPA) Life Safety Code, 2012
Baltimore County Fire Protection Code, 2013
Baltimore County Public Schools Facility Standards
Fire Prevention Code, NFPA 1, 2013
Fire Suppression System
The 1961 building currently has no automatic fire suppression. The original school does have an active
standpipe system. The 2002 addition was constructed with a full automatic fire suppression system and a
standard pipe system.
The existing building has limited sprinkler system piping serving only the trash room and portion of the
boiler room. The 2002 addition is a wet pipe sprinkler system and the fire connection has blanked off
portions that appear to be sized for connection to the original building. This system is provided by its own
6” water connection to the building. The 2002 addition is separated into 3 zones, one per floor. All areas
of the addition are classified as light hazard except for storage rooms, mechanical rooms, and electrical
rooms.
NFPA requires 65 psi at the top of the sprinkler standpipe; this would require a fire pump, however most
jurisdictions will allow a waiver to this policy proving there is enough flow for the sprinkler system. The
2002 addition did not include a fire pump and did not meet the 65 psi requirement. The sprinkler zones
should be coordinated to match the fire alarm zones.
The auditorium is part of the 1961 building and is not sprinkled. The stage was built before smoke control
ventilation was required and therefore may not meet the current requirements. This will be investigated as
part of the next school renovation.
Recommendations for Fire Suppression System
The existing domestic water service line is not large enough to accommodate the water demand of a full
coverage automatic fire suppression system. A fire flow test will need to be performed during the design
phase to develop the parameters. Once the water service upgrade is complete, the automatic fire suppression
system can be installed to serve the entire facility.
6. CONVEYING SYSTEMS
Introduction
The building has two existing elevators. One is a part of the original building. The other is in the newer
addition and is in good condition.
Recommendation for Elevators
The original elevator should be upgraded with new finishes, machinery, and controls.
Baltimore County Public Schools Limited Renovation Assessment | Page 29 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
7. MISCELLANEOUS SYSTEMS
Roof Systems
New built-up roofing was installed on the entire building in 2014.
Recommendation for Roof Systems
None.
Exterior Walls
New windows, curtainwalls and exterior doors were installed in the original section of the building in 2014.
Recommendation for Wall Systems
Minor masonry repairs are needed, mostly at corners, due to lack of control joints.
Floors
The original building corridors and stairs have terrazzo flooring. Cracks have developed in several
locations. The terrazzo in the stairs is in poor condition. The treads and risers are very worn and pose a
safety hazard.
The original building has 9x9 floor tiles in the classrooms and offices. Some classrooms have had 12x12
tiles installed. Asbestos reports indicate that both 9x9 and 12x12 tiles and mastic contain asbestos.
Recommendation for Floor Systems:
All stair treads and risers (except in newest addition) should be replaced.
All vinyl flooring should be abated and replaced during a renovation project. The tiles were in poor
condition in numerous instructional areas.
Terrazzo floors need minor repairs.
Baltimore County Public Schools Limited Renovation Assessment | Page 30 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Ceilings
The original ceiling tiles are 12x12. They are in poor condition and most likely contain asbestos. They
should be replaced with an acoustical tile ceiling as part of the air-conditioning project for the school.
Recommendation for Ceiling Systems
All classroom ceilings in the original building should be replaced.
Windows
Partial window replacement has occurred in 2014 and 1999. Numerous window air-conditioner units
penetrate the curtain wall windows and panels. These will no longer be needed with the new air-
conditioning project.
Recommendation for Window Systems
Select replacement of damaged and deteriorated window wall system.
Baltimore County Public Schools Limited Renovation Assessment | Page 31 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Doors
Existing interior doors are in poor condition. They frequently incorporate louvers, wire glass, and hardware
that does not meet ADA guidelines. Double doors with center mullions into stairwells are too narrow to
comply with code requirements. These door assemblies do not have any fire rating.
Classroom entry doors do not provide proper clearances to meet ADA guidelines. One entry into most of
the classrooms in the original building will need to be expanded. This expansion will require the removal
of masonry wing walls and lockers adjacent to the construction work area. Classroom door hardware does
not provide the most current security lock-down functions as required for BCPS.
Doors in the 2002 classroom addition meet fire and ADA standards. Existing classroom hardware does not
have a special classroom lock-down function.
Exterior doors are FRP and in poor condition. Double doors are too narrow (each leaf) to comply with
ADA guidelines.
Recommendation for Door Systems
Replace existing doors and provide ADA hardware. Classroom entrances should be renovated to
provide width clearances that will comply with ADA guidelines.
Baltimore County Public Schools Limited Renovation Assessment | Page 32 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Casework
Existing interior casework is original and is in poor condition. Science rooms were renovated in 2004 and
the casework is in good condition.
Recommendation for Casework
Replace existing casework in the original part of the building.
Building Entry / Security
The existing main entrance to the building is under a canopy from the bus loop. The only security is at the
exterior door, where a visitor needs to be buzzed in by the office staff. Once inside the door, they are asked
to enter the office; however, they have access to the corridors of the school.
Baltimore County Public Schools Limited Renovation Assessment | Page 33 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
The lobby is at a lower level than the main corridor. Currently, there is not a ramp or lift to allow a
wheelchair to gain access to the corridor without going outside or through the main office and navigating a
steep wooden ramp.
WOODLAWN HIGH SCHOOL FEASIBILITY STUDY D. SITE ASSESSMENT
Baltimore County Public Schools Site Assessment | Page 34 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
1. Site Assessment
Introduction
Woodlawn High School occupies approximately 56.2 acres in the west-southwestern region of the
County, bounded by 2 County public roads and 2 streams. Woodlawn Drive lies on the west side of the
property and contains the main entrance and secondary entrance to the playing fields. Gwynn Oak
Avenue lies on the east, near the track field. Dead Run lies on the north side of the property, while a
tributary to Dead Run lies on the south side of the property. It is situated in a mixed site mostly
comprised of detached single family residences, commercial businesses, and industrial areas. The site
contains 5 baseball / softball diamonds, 3 multi-purpose fields, one football / soccer / lacrosse field within
a 400 meter running track, 4 tennis courts, and an outdoor basketball / hardcourt. The original school
building was built around 1961, an addition was constructed around 2002, and the fields were built about
1961. There are 2 large parking lots, the larger, original lot is on the north end of the building and a
smaller one on the south end adjacent to the addition.
Site Grades
The lowest portion on the site is at the south end along the stream and Gwynn Oak Avenue roughly at
elevation 330. As you move north toward the school building, the elevation quickly rises to a peak of roughly
385 which represents the first floor of the school building, and then the site drops in elevation toward Dead
Run roughly at 335 elevation point. The school building is perched in relation to the surrounding areas of the
site, which include the playing fields and parking. There is a significant elevation drop from the building to
nearly all of the playing fields, thus the site was not ADA accessible when constructed, and very few site
improvements have been made to update the exterior site to current ADA codes.
Soils
Soils from actual boring reports indicate surface layers of sand, clay, and mica, which vary from 2 foot to
20 feet deep, with disintegrated rock beneath those soils.
One storm water management surface facility exists just south of the southern parking lot. Another storm
water facility exists on the north end, below the large parking lot on the northern side of the property, near the
library. The remainder of the site is traditional inlet and storm drain construction, including roof runoff piped
through the building to the closed pipe system. Portions of the property located along the streams are within
floodplains and stream buffers, and cannot be developed further.
A footbridge did exist on the east side of the property crossing Dead Run and connecting the school property
with the community at Englewood Avenue and Dogwood Road. This footbridge was recently removed by the
County DPW due to its age and condition.
Hydrology
The site is surrounded by traditional surface inlets and curb inlets. There appears to be an adequate
number of drains for the site. However, the condition of the inlets, head pieces, and boxes is poor, and
many need repair or replacement.
Vehicle Circulation
Vehicle circulation is adequate at this site. Bus and car traffic share the same entrance / exit driveway, but
they are separated at the bus pick up / discharge areas. There is a maintenance access from the southern
parking lot to rear boiler room area and shop wing. This maintenance access does not connect to the north
Baltimore County Public Schools Site Assessment | Page 35 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
side of the building. There is another access off the northern lot to the cafeteria area. A fenced area with a
large shed resides off the northern parking lot for Grounds maintenance equipment. The concrete sidewalk
leading to the track / field has been widened with asphalt, and this serves as a maintenance vehicle access to
the lower fields and track.
The condition of most of the paving is poor. The curb faces are only exposed 3 to 4 inches in some areas,
most concrete gutter pans are not exposed, indicating the asphalt has been overlaid at least one time. The
paving has indications of age with signs of light cracking to small holes in some areas. The curbs in some
areas are completely disintegrated, and do not exist. Other curbs are mis-aligned and severely worn. Many of
the storm drain inlets need replacement. Some of the concrete sidewalks are in poor to fair condition, with
indications of heaving and cracking. Some exterior concrete stairs are deteriorating, and show signs of
previous repair attempts. There are several administrator parking spaces along with a few spaces indicated as
ADA in a small parking section off the bus loop, and closest to the main entrance. However, the parking
spaces indicated ADA are not in compliance. In fact, there is an insufficient number of ADA curb ramps that
restrict access to the indicated parking areas. Improvements are desperately needed on the site to bring the
school up to accessibility code requirements. There does not appear to be direct ADA access from Woodlawn
Drive. There are very few ADA access areas to the building.
The exterior pole mounted lighting in the parking areas is represented by two different styles. Most of the
poles and foundations were installed 50 plus years ago. The fixtures have been replaced, mostly within the
last 20 years. These fixtures throw light outward rather than directly down. The spacing between poles varies
and at times exceeds 120 to 160 feet. Some poles are surrounded by trees, creating a lack of uniformity in
foot-candle levels.
The useful life of concrete foundations, underground conduit and wiring is 50 years, while the fixture life is
20 -25 years. Based on the age of the components of the system, these lights should be replaced with the new
lighting providing LED type fixtures which reduce energy costs while achieving increased lighting.
Pedestrian Circulation
While the front and main entrance to the school is relatively flat along a portion of the bus loop toward
the auditorium and contains a nice concrete plaza area without steps to the front door, the ADA
accessibility to the school is extremely poor. The ADA parking spaces are not configured to current code.
There are very few, and in some cases zero, curb ramps at driveway crossings. One curb ramp exists at
the front door, but does not provide complete access to parking as other ramps are necessary.
Accessibility to the playing fields and courts is also restricted. With the building perched at the high point of
the property and the fields all built at the perimeter and lower elevations, the change in elevation in some
areas is too severe to create ADA accessibility without the installation of a series of switchbacks, or a new
road path to the fields with an attached dedicated ADA parking area. The foot path from the school building
to the track field is not ADA accessibility compliant. The footpath to the ball diamonds is not compliant as
well.
Amenities
The running track has a latex rubber surface, but is showing signs of age and wear. The playing field inside the track is synthetic field turf in good condition, with gooseneck style football goals.
There is bleacher seating within the track / football field area, capable of holding several hundred spectators,
including ADA seating capacity. However, there is no permanent public rest room within the bleacher area,
Baltimore County Public Schools Site Assessment | Page 36 Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
and without portable toilets on site the bleachers would not be ADA compliant. It is unclear where the ADA
parking for the bleachers is located on the site.
The tennis court and hard court surfaces are in need of resurfacing.
The court fencing is rusted and should be replaced.
Most of the ball diamond backstop fencing is corroded as well.
WOODLAWN HIGH SCHOOL FEASIBILITY STUDY E. EDUCATIONAL ENHANCEMENTS
Baltimore County Public Schools Educational Enhancements | Page 37
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
1. EDUCATIONAL ENHANCEMENTS
Introduction
The existing building has a number of educational deficiencies that involve room size, program proximities
and current programmatic standards. Most of the building instructional spaces (except in the 2002 addition)
are not air-conditioned.
Administration and Main Entrance
The front doors are controlled with a remote strike that must be released by office staff when a visitor
buzzes in at the entrance. Once admitted into the school, there is no security vestibule to limit access into
the building. Also, the entrance is on a lower level and does not provide ADA access to the main building.
The main office and guidance suite do not provide adequate space for security and operations for a high
school. An existing ramp in the Guidance area is not ADA compliant. Staff toilet rooms are small and are
not ADA compliant.
Recommendations for the Administration and Main Entrance
New security vestibule at main entrance.
Renovate area to provide ADA accessibility.
Renovate toilet rooms for ADA accessibility.
New casework, floors, ceilings, and lighting.
New interior doors with ADA hardware.

Science Rooms
The science rooms were renovated in 2001 and 2004 and are in fair condition.
Recommendations for the Science Rooms
Two Biology science rooms would be moved to the ninth grade academy (currently Art Room
locations) and two art rooms would replace these science rooms.
No architectural upgrades are planned for these rooms.
Art Rooms
Currently located in the ninth-grade academy wing, two of the four art rooms are needed for ninth grade
science.
Recommendations for the Art Rooms
Two Art rooms would be located in the main building where two science rooms were moved to the
ninth grade academy.
New casework, floors, ceilings, lighting, IT infrastructure and ADA accessibility.
Replace chalkboards/tack boards with new marker boards.
New interior doors with ADA hardware.
Music Rooms
Music rooms are located in the ninth grade academy addition.

Media Center and Support Rooms (Computer Labs)
The Library and adjacent Computer Lab are in fair condition.
Recommendations for the Media Center
No architectural upgrades are planned.
Health Suite
This space does not meet current BCPS spatial and privacy requirements. The toilet facilities are not ADA
accessible. Access with a stretcher would be difficult without navigating stairs or steep ramps.
Recommendations for the Health Suite
Renovate to meet BCPS standards.
Provide ADA accessibility.
Baltimore County Public Schools Educational Enhancements | Page 40
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Home Economics Room
These rooms are original and in poor condition. Casework and appliances are dated. Ventilation is not
provided at the cooking stations. Electrical outlets are inadequate for current requirements. Complete
renovations should be considered.
Recommendations for the Home Economics Rooms
New casework, floors, ceilings, lighting, IT infrastructure and ADA accessibility.
Replace chalkboards/tack boards with new marker boards.
New interior doors with ADA hardware.
Industrial Arts Rooms
These shops are located on the lower level of the technology annex. One shop is used for Bio-Med Project
Lead the Way. Two shops are used for Science Tech-Ed curriculum. Shop equipment is limited but dated.
ADA access is not provided to this level of the building. Internal circulation requires passing through
adjacent shops unless the person goes up the stairs to the upper floor and down another set of steps to the
shop. A central corridor with ADA access would be recommended.
Recommendations for the Industrial Arts Rooms
No architectural upgrades are planned.
Baltimore County Public Schools Educational Enhancements | Page 41
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Typical Classrooms
At approximately 750 square feet, many classrooms are too small for 32 students per class. Most
classrooms use chalkboards and projectors are portable units on carts or stands. Entrances to the rooms are
not ADA accessible. Door hardware is not ADA compliant. The existing casework is mostly original and
should be replaced. Existing flooring and ceiling tiles contain asbestos. Lighting levels are inadequate.
Electrical capacity in the classrooms is inadequate to meet the demands of the users.
Reconfiguration of the classroom entry is required. Door louvers will need to be eliminated when air
conditioning is added. To provide ADA accessibility, adjacent lockers will need to be eliminated at new
recessed classroom entrances. Removal of glass transom panels above the lockers in the corridor will be
required.
Recommendations for Typical Classrooms
New casework, floors, ceilings, lighting, IT infrastructure and ADA accessibility.
Replace chalkboards/tack boards with new marker boards.
New interior doors with ADA hardware.
Ninth Grade Academy (2002 Addition)
As configured, does not contain any science classrooms within close proximity. Currently, students need
to use the general science labs in the main building. The Art rooms for the entire school are located in this
wing of the building. It is proposed to renovate these rooms for ninth grade Biology science classrooms.
Recommendations for the Ninth Grade Academy
No architectural upgrades are planned.
Two Art rooms from the ninth grade academy would be located in the main building where two
science rooms would be located in the ninth grade academy.
Baltimore County Public Schools Educational Enhancements | Page 42
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Special Education
Currently all spaces are located in the classroom addition. Spaces should be dispersed throughout the
school. Life Skills needs a residential kitchen and washer.
Recommendations for Special Education
No architectural upgrades are planned.
Faculty Learning Space
Currently, there is no large group assembly space available for faculty learning.
Recommendations for Faculty Learning Space
No architectural upgrades are planned.
Auditorium
This space is air-conditioned. The auditorium meets ADA guidelines. The only means for a handicapped
audience member to get on the stage is to leave the auditorium space and re-enter from the corridor adjacent
to the stage. The Advance Path program is located in space under the auditorium and is not ADA accessible.
Recommendations for Auditorium
No architectural upgrades are planned.
Baltimore County Public Schools Educational Enhancements | Page 43
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
Gymnasium
The gym is air conditioned. A chair lift allows handicapped access to the gym level. The floor was replaced
in 2007 and is not included in proposed renovations. Boys and Girls Locker Rooms are located under the
gym. They are not ADA accessible. A Weight Room is located above the gym lobby and is not ADA
accessible.
Recommendations for Gym, Locker Rooms, and Weight Room
No architectural upgrades are planned.
Faculty Offices
Currently, all faculty offices are located in one location. It would be preferred to have offices dispersed
throughout the school.
Recommendations for the Faculty Offices
New casework, floors, ceilings, lighting, and ADA accessibility.
New interior doors with ADA hardware.
TV Studio
This space is outdated and does not meet current BCPS requirements.
Recommendations for TV Studio
No architectural upgrades are planned.
Corridors
Doors are not fire rated and individual door leafs are not ADA compliant. Drinking fountains are not ADA
compliant. The concrete floor in the walkway between the main building and auditorium/gym has cracked
and settled significantly. This creates a tripping hazard. The exterior bridge between the main building
and technology wing is exhibiting signs of severe rusting of steel lintels. Railings do not meet current
codes. Widespread use of wire-glass no longer meets code. Existing lockers are original and should be
considered for replacement during a major renovation.
Baltimore County Public Schools Educational Enhancements | Page 44

New classroom entrances will be ADA accessible. Adjacent lockers will be modified.
Repair rusted steel lintels and spalled concrete.
Repair concrete slab between main building and auditorium/gym.
New ceilings and lighting.
New ADA drinking fountains.
Stairs
Stair treads and nosings are in poor condition and pose a safety issue. Railings are not ADA compliant.
Recommendations for Stairs
New fire rated doors and walls.
New stair treads and nosings.
New ADA compliant handrails and guards.
Elevator
The elevator in the main building only provides access to the three classroom floors and the upper level of
the mechanical space under the classrooms. It needs to be replaced to meet ADA standards. Two additional
elevators and a vertical chair lift are needed to provide ADA access to the numerous different levels
throughout the school.
Recommendations for Elevator
Provide new chair lift and two elevators to provide ADA access to most areas.
Upgrade existing elevator.

Baltimore County Public Schools Schedule and Phasing | Page 46
Office of Engineering and Construction February 18, 2016
Woodlawn High School Feasibility Study
1. SCHEDULE AND PHASING
Schedule
An outline of key milestone dates are shown below for information purposes only. This schedule is
approximate and subject to change.
Design Phase January 2016 - October 2016
Construction Documents Complete October 2016
Contractor Procurement November 2016 – February 2017
Notice to Proceed March 2017
Substantial Completion August 2019
Final Completion October 2019
Phasing
The final determination of the types and extent of building systems included in the limited renovation and
the quantity of educational enhancements implementation will impact the design and construction
schedules. The duration of construction phasing will be impacted by the limited renovation and the
quantity of educational enhancements final selection for this project. It is anticipated that the project will
require phasing to allow three full summers within the duration of the construction.
Construction phasing to accommodate the educational enhancements for Library/Media Center, Art
Classroom, Technology Classrooms due to size constraints are usually require a duration exceeding the
limited eight weeks available for summer construction and will thus require relocation of these
educational enhancements in a large double wide relocatable. It is anticipated that the limited renovation
will require six to eight temporary classrooms and one large double wide relocatable. It is also
anticipated that cooling will not be on line until substantial completion.
