EXECUTIVE SUMMARY

Executive Summary ǀ 02


Introduction

Carroll County Career and Technology Center

(CCCTC) is located on a 68.56 acre parcel shared

with Westminster High School. The property is

bounded by single family residential homes and

Hook Road to the north, New Washington Road

(Rte. 97) to the east, and a Carroll County Fire

Training facility to the south. The west

boundary of the property lies along Washington

Road (Rte. 32). The building was constructed in

1969 with an addition added along the south

side in 1986. Five relocatable classrooms are

located adjacent to the building on the west

side and are utilized for Health and Information

Technology programs. The state rated capacity

of the school is 380, however the students are

enrolled and accounted for at their home high

schools. The current enrollment for semester 1

is 769 students and 815 students for semester

2. There is a wait list of approximately 300

students.

The site is accessed via two points along

Washington Road (Rte. 32) and a third along

Hook Road. Bus traffic typically enters from the

Hook Road or northern Washington Road

access point onto a campus road (Washington

Lane) leading to a continuous campus drive

aisle loop encircling the campus. The drive aisle

loop serves both Westminster High School and

CCCTC. The south access point along

Washington Road serves student, parent, and

staff traffic for CCCTC in addition to serving

Westminster High School students and buses.

Upon entering the common drive aisle access

point, CCCTC traffic is directed to the right

toward a common parking lot for students,

staff, and visitors. CCCTC’s receiving area for

deliveries is also located along this portion of

the drive aisle northwest of the building. The

CCCTC parking lot is shared with a community

media center on the southwest corner of the

campus. The drive aisle loop continues along

the west between the building and parking lot,

acting as both campus loop road and bus

queuing area. Additional parking lots for

Westminster High School are located north of

CCCTC. Grassed multi‐purpose play fields with

overlapping softball and baseball diamonds,

practice field for football, field hockey field, and

football/soccer stadium with track are located

to the northeast of CCCTC. Fields are utilized by

Westminster High School.

The existing school suffers from insufficient

space to accommodate the proposed

educational program and outdated systems.

Additionally, there is a wait list of students

hoping to enroll that cannot be accommodated

without additional space to expand the

programs. The facility is aging and suffers from

a combination of mechanical, electrical,

plumbing, accessibility, and educational

deficiencies.

With broad and accelerated change that

continues to influence learning and instruction,

the current Carroll Career and Technology

Center cannot keep pace with the facility

demands of today’s educational imperatives.

In short, the school no longer reflects a

standard for career and technology school

facilities that is consistent with the Board of

Education’s vision for Carroll County and

requires modernization or replacement.



Purpose The purpose of this feasibility study, commissioned by Carroll County Public (CCPS), was to direct the

study team to assess the condition of the existing building and site, offer recommendations for

improvements or replacement of current facilities, and present four options for consideration by the

Board of Education (BOE).

A program inventory was developed by the Study Team in conjunction with Hord Coplan Macht, using

the school’s current inventory as a baseline and proposing space improvements based on enrollment

needs including wait list, state education guidelines, and programs from comparable career and

technology facilities in Maryland. Each design option presented in this document reflects an approach

to the proposed educational program: Option A addresses the wait list enrollment space needs and

systemic upgrades only to provide a more modestly scaled intervention option while Options B, C, and D

address the educational program in full, including wait list.

The feasibility study team worked closely with the study team to determine the most reasonable

approach to each option. This study includes a photographic and narrative assessment of the existing

facility, including a preliminary evaluation of compliance with current building and life safety codes.

Descriptive summaries and illustrations are provided for each option, followed by appendices that

include proposed costs and life cycle cost data.



Findings

The existing school has insufficient space to accommodate the proposed educational program, outdated

systems, and inefficient adjacencies. It is an aging facility that suffers from a combination of mechanical,

electrical, plumbing, and accessibility deficiencies and needs to be modernized. These deficiencies

include:

Site:

Access point/route that mixes cars and buses rather than separating them.

Parking lots need resurfacing.

Building:

Administration suite lacks storage for general use and records.

Guidance suite is comingled with main administration

Health suite does not meet COMAR requirements – all health services are provided from a single office that is accessed through the main office.

Maintenance personnel share space with the building maintenance program for students.

Engineering program is lacking in quantity of classroom and storage spaces.

Manufacturing Lab is undersized and program lacks adequate storage space.

Drafting program lacks dedicated storage space.

Welding program lab and classroom are undersized and there is no locker space for female students.

Finishing area of welding is housed in a mezzanine, making it inaccessible to students/staff who cannot use stairs.

Textiles/Fashion design space is undersized and configured in an inefficient shape, making space deficiencies worse.

Cosmetology program lacks the appropriate quantity of classroom spaces and its support spaces are undersized.

Culinary Arts program is undersized in all programmed spaces and locker rooms are located in storage closets.

Special education space is grossly oversized while math, English, and computer spaces are undersize.

Food service lacks a dedicated storage room.

Academy of Health Professionals program is deficient in size, number of lab spaces, number of classroom spaces, and required support spaces. A portion of this program is located in a relocatable classroom space.

Biomedical program labs are undersized and the program lacks dedicated storage space.



Criminal Justice program lab is undersized, located in a relocatable classroom, and lacks the required amount of classroom spaces.

Construction programs (HVAC, Carpentry, Masonry, Electrical, and Building Maintenance) have undersized lab and classroom spaces and do not have locker facilities for female students. Storage space is highly concentrated in mezzanines, making it inaccessible for students/staff who cannot use stairs.

Building maintenance program has no dedicated space. They share the building services staff space (see item above).

Video production lacks dedicated support spaces, possesses an undersized lab space, and is currently located in a relocatable classroom.

Print production lacks a photo lab. Program currently uses a mechanical room for photo development.

Computer Technology and CISCO/Networking programs have undersized labs, too few labs spaces, and no dedicated storage. CISCO is currently located in a relocatable classroom.

Automotive Technology is undersized by nearly one half the programmed size.

Collision Repair program is undersized and lacks locker space.

Heavy Equipment and Truck Technology (Diesel) is undersized by approximately 33%.

Staff resource rooms do not exist for the career clusters. Staff currently share space with the special education area for this use.

Retail spaces (cosmetology, textiles/fashion, and culinary) do not have dedicated public access points. Patrons must walk through the building to access these spaces.



Proposed Design Options

The development of the following design options included an assessment of the Carroll County Career

and Technology Center building and concluded that the building has educational and functional

limitations. It does, however, provide opportunity to create multiple design options that address the

requirements described in the proposed space summary developed by the Study Team. The proposed

design options went through a series of design review meetings with members of the Study Team.

OPTION A ‐ PARTIAL MODERNIZATION

OPTION B ‐ MODERNIZATION

Option A ‐ Partial Modernization

Partial Modernization (Option A) includes

constructing a 21,000 sf addition that contains

spaces for the wait list programs indicated in the

program inventory space summary. Proposed work

also includes complete renovation of the existing

building to bring the entire building into

conformance with current building and life safety

codes. Enlargement of program space within the

existing building is not provided as part of this partial

modernization, and life safety renovations may

reduce the existing instruction space to

accommodate the modifications. Relocatable

classrooms will remain during and after completion

of the partial modernization. Maintaining building

occupancy and operation will require a multi‐phase

construction process.

Option B ‐ Modernization

Modernization (Option B) includes renovation of the

existing building to bring the entire building into

conformance with current building and life safety

codes and reconfiguration of the spaces to better

accommodate the proposed program. It will also

include 91,185 sf in additions to be in compliance

with the proposed program. Existing detached

building for auto collision repair program will be

demolished. Maintaining building occupancy and

operation will require a multi‐phase construction

process.



OPTION C ‐ REPLACEMENT

OPTION D – REPLACEMENT OFFSITE

Option C ‐ Replacement

Replacement (Option C) includes a design of a new

two‐story facility on the existing campus to be in

compliance with the proposed program, including

square footage and proper spatial and educational

relationships. The existing building will remain

operational during construction of the new building

and will be demolished when the new building is

completed. The site design will address traffic

patterns, parking, and replacement athletic fields at

the location of existing building to be demolished. The

Community Media Center will be replaced in this

option to provide space for the relocated athletic

fields and will be constructed as part of the new

building.

Option D – Replacement Offsite

Replacement Offsite (Option D) includes a design of a

new two‐story facility to be in compliance with the

proposed program, including square footage and

proper spatial and educational relationships. This

option will be constructed on a site to be determined.

The existing building will remain operational during

construction of the new building and the building will

be vacated when the new building is completed,

leaving it available for future use. The new site design

will optimize traffic patterns, parking, and stormwater

management at the new site.

Alternative Sites

As part of the design option review process, CCPS directed HCM to review the viability of locating portions of CCCTC programs at existing CCPS facilities. HCM reviewed potential spaces at Westminster High School, South Carroll High School, and North Carroll High School. In each case, space could be utilized to reduce the size of the required additions or size of a replacement facility. However, renovation costs would be required at similar $/SF capital renovation costs as required to renovate the existing facility to accommodate the relocation of the programs to these spaces. Operational costs (i.e. transportation costs, additional staffing, utility costs, etc.) also will need to be accounted for and will vary significantly between currently occupied facilities and buildings that are not currently in use. Refer to Appendix A for a cost breakdown of work typical for renovation at Westminster High School if some programs are relocated as an example. The proposed options do not take relocation of programs to other sites into account for purposes of this study.


HISTORY

History ǀ 03


Historical Summary

The existing building, constructed in 1969, has been expanded on one occasion and has no historical significance. A stepped, one story addition was constructed in 1986 and contains high bay classroom and lab spaces for the HVAC, Welding, and Heavy Equipment and Truck Technology (Diesel) programs. In 1998, the original storage building on the west side was renovated to be shop space for the Auto Collision Repair program.

Years of Construction Plan

Maintenance, repair, and replacement projects have occurred throughout the life of the building.

Projects performed in the last 15 years include:

2001 ‐ Replace Aluminum Exterior Doors 2014 ‐ Exterior Lighting Upgrade

2002 ‐ Replace Cooling Tower 2014 ‐ Security Upgrades (Access Control

2003 ‐ Replace VAT flooring with VCT and Visitor Management System)

2005 ‐ Replace VAT flooring with VCT 2015 ‐ Roof Replacement


EDUCATIONAL GOALS

Educational Goals ǀ 04


Educational Program

A primary goal of this study is to analyze the educational adequacy of the existing building to determine

if it can accommodate the proposed educational program and if not, determine what is required to

achieve the educational goals put forth by the Study Team. This includes accommodating the current

enrollment of 769 semester 1 students, 815 semester 2 students, and a wait list of 300 students. A

program inventory created collaboratively by Carroll County Public Schools and Hord Coplan Macht was

used as a baseline. Program inventory was based on enrollment needs including wait list, state

education guidelines, and programs from comparable career and technology facilities in Maryland. The

program is organized into the six career clusters, administration, and general education. The six career

clusters are:

Engineering

Business/ Retail

Health & Human Services

Construction

Computer Related

Transportation

When a modernization project moves forward, a Planning Committee will be formed and they will

develop a detailed educational specification at that time.

An analysis of the proposed program versus the existing building identified an additional 82,457 gross

square feet is required to be added to the existing building to accommodate the proposed program (see

Program Summary Table at the end of this section). The additional square footage is addressed in the

four design options presented in this report. The analysis also revealed many educational program

deficiencies with the existing building that will require reconfiguration and expansion of the existing

building to accommodate. A partial list of deficiencies is as follows:

Administration suite lacks storage for general use and records.

Guidance suite is comingled with main administration.

Health suite does not meet COMAR requirements – all health services are provided from a single office that is accessed through the main office.

Maintenance personnel share space with the building maintenance program for students.

Engineering program is lacking in quantity of classroom and storage spaces.

Manufacturing Lab is undersized and program lacks adequate storage space.

Drafting program lacks dedicated storage space.

Welding program lab and classroom are undersized and there is no locker space for female students.

Finishing area of welding is housed in a mezzanine, making it inaccessible to students/staff that cannot use stairs.



Textiles/Fashion design space is undersized and configured in an inefficient shape, making space deficiencies worse.

Cosmetology program lacks the appropriate quantity of classroom spaces and its support spaces are undersized.

Culinary Arts program is undersized in all programmed spaces and locker spaces are located in storage closets.

Special education space is grossly oversized while math, English, and computer spaces are undersize.

Food service lacks a dedicated storage room.

Academy of Health Professionals program is deficient in size, number of lab spaces, number of classroom spaces, and required support spaces. A portion of this program is located in a relocatable classroom space.

Biomedical program labs are undersized and the program lacks dedicated storage space.

Criminal Justice program lab is undersized, located in a relocatable classroom, and lacks the required amount of classroom spaces.

Construction programs (HVAC, Carpentry, Masonry, Electrical, and Building Maintenance) have undersized lab and classroom spaces and do not have locker facilities for female students. Storage space is highly concentrated in mezzanines, making it inaccessible for students/staff who cannot use stairs.

Building maintenance program has no dedicated space. They share the building services staff space (see item above).

Video production lacks dedicated support spaces, possesses an undersized lab space, and is currently located in a relocatable classroom.

Print production lacks a photo lab. Program currently uses a mechanical room for photo development.

Computer Technology and CISCO/Networking programs have undersized labs, too few labs spaces, and no dedicated storage. CISCO is currently located in a relocatable classroom.

Automotive Technology is undersized by nearly one half the programmed size.

Collision Repair program is undersized, lacks a dedicated paint booth area (it currently uses shop space), and lacks locker space.

Heavy Equipment and Truck Technology (Diesel) is undersized by approximately 33%.

Staff resource rooms do not exist for the career clusters. Staff currently share space with the special education area for this use.

Retail spaces (cosmetology, textiles/fashion, and culinary) do not have dedicated public access points. Patrons must walk through the building to access these spaces.



In addition to the programmatic deficiencies noted above, there are deficiencies and inefficiencies with locations of programs within the existing building. A partial list follows and will be refined more when the detailed educational specification is written and identifies specific adjacency requirements that need to be met.

The cosmetology salon, culinary restaurant, and textiles/fashion lab do not have exterior access for community patrons.

Health and Biosciences cluster spaces are spread out across four locations over two floors, with one being a relocatable classroom.

Engineering cluster is spread out across three locations, including space that divides the Information Technology cluster.

Business and retail spaces are spread out across three locations.

Main entry is not based on prevailing site access point/route.

Elevator location is as remote from main entry as possible, requiring a user to traverse the entire building to use it.

Building services space and loading dock are not optimally located.



The following table summarizes the existing program and compares it to the proposed program. The programs in the table are organized by career cluster. Items highlighted in red identify the major programmatic deficiencies.

Program Summary Table

Items highlighted in red are deficiencies with the current building that do not meet the proposed program. Subtotals have

been provided per career cluster for an additional level of information.



The following table summarizes the program spaces that are required to be added to accommodate the current Wait List. The programs in the table are organized by career cluster.

EXISTING CONDITIONS

SITE

Site Description

The subject site for Carroll County Career &

Technology Center is located at 1229

Washington Road, Westminster, Maryland

21157. The site is approximately 68.56 acres

and currently contains the Career & Technology

Center building, five (5) relocatable classroom

buildings and the existing Westminster High

School building. The property is also known as

parcel 412 as shown on tax map 52, grid 7. The

tax account number for the property is 07‐

003528. The site is owned by the Board of

Education of Carroll County and the deeds for

the property can be found in the Carroll County

Courthouse at Liber 436, Folio 628.

The property is bounded by Washington Road

(MD Route 32), a retirement home facility, and

an apartment complex to the west, Municipal

buildings to the south, single family residential

homes and New Washington Road (MD Route

97) to the east and single family residential

homes and Hook Road to the north.

Site Circulation and Parking

There are three existing access points onto the

site, one of these access points is located along

Washington Road (MD Route 32). The other

two access points are located along Washington

Lane. The first access point along Washington

Road is located opposite the entrance to the

Golden Living Center just south of Pennington

Place. This access point provides access to the

Career & Technology Center, Westminster High

School shared parking area, Westminster High

School bus loop and the loop road that runs

around both buildings. The main parking lot for

the Career & Technology Center is located on

the west side of the existing building and is also

accessed from the loop road. This parking lot is

shared with the existing Community Media

Center that is located on a county owned parcel

that wraps around the southern portion of the

parking lot. The Career & Technology Center

main parking lot contains approximately 230

parking spaces including 14 ADA accessible

parking spaces. The shared parking lot located

off the northwest corner of the Career &

Technology Center contains approximately 157

parking spaces including 5 ADA accessible

parking spaces.

The second access point along Washington Lane

appears to mainly serve the Westminster High

School. The third access point is also located

along Washington Lane and serves as access to

both the Career & Technology Center and

Westminster High School. There is an

additional parking lot located off of this access/

loop road that appears to be primarily for the



high school. This parking lot is located off the

northeast corner of the Career & Technology

Center and contains approximately 91 parking

spaces.

Zoning Information

The property is currently zoned as C ‐

Conservation District. The properties

surrounding the school site to the east are

zoned Residential (R‐20,000). The properties to

the north and west are zoned Residential (R‐

10,000). The properties to the south are zoned

Conservation District (C).

The following specific development standards

for the Conservation zone (an excerpt from Title

15‐Chapter 158 Zoning Regulations) of the

Carroll County Maryland Code of Ordinances

are provided for guidance only. Per Chapter

158, schools are considered a principal

permitted use.

B 22% B ML No Fair

Site Topography

The site topography has gradual changes in

elevation. The highest elevations are along the

northern portion of the property. From there

the grade slopes down toward the south

gradually to the two plateaus of the site where

the buildings and fields are located. The grades

near the building are slightly higher than the

field grades. The grades continue to gradually

slope across the fields toward the southern

portion of the property. In the vicinity of the

Career & Technology Center 1986 addition, the

grades come up approximately 5’ from the

remainder of the building on the southern side

and then they fall off quickly toward the south.

Water Service

Based on our review of existing documentation,

it appears that the existing building is serviced

from the existing 12” water main located within

Washington Road. Several fire hydrants exist

on‐site.

Sanitary Sewer

The existing building is currently served by a

public sanitary sewer system. The existing

sewer leaves the building in several locations in

the back along the eastern building wall. The

sewer line is 8” in size and is collected at a

manhole just off the loop road to the east.

From the manhole, the 8” sewer line leaves the

site on the south side where there is an existing

8” public sewer line.

Storm Drains

Storm water around the site is conveyed via a

combination of overland flow and closed storm

drain system. Primarily, the closed storm drains

convey runoff from the existing building roof

and paved parking areas. The storm drains

range in size from 6” to 60”. The majority of

the storm drainage discharges on the

southeastern portion of the property into an

existing stormwater management pond.



Stormwater Management

The site does currently contain one stormwater

management facility. This facility is a pond

located on the southeastern portion of the site.

Any new construction that occurs will be

required to meet the requirements established

by the Maryland Stormwater Act of 2007.

These guidelines establish a process by which

new construction needs to utilize sustainable or

environmental site design (ESD) to the

maximum extent possible to satisfy water

quality requirements. ESD’s include but are not

limited to micro‐bio retention, dry and/or wet

swales, rain gardens, etc. Attempts should be

made to provide for impervious disconnects

and to allow for adequate open space to

construct multiple smaller facilities throughout

the site to satisfy these requirements.

Floodplains, Wetlands, and Waterways

The site is not located within the 100 year

floodplain as delineated on FEMA flood

insurance rate map 24013C0215D. The site is

located in zone X which means an area

determined to be outside the 0.2% annual

chance floodplain. A review of the Maryland

Department of Natural Resources (DNR)

mapping indicates that onsite wetlands do exist

on the site. The wetland areas are located near

the existing pond. It also appears that a portion

of Middle Run also runs through the

southernmost corner of the site.

Landscape, Trees and Forest Conservation

There are no existing forested areas located on

the site. There are several groupings of trees

located sporadically around the site. A forest

stand delineation and forest conservation plan

will be required for any development that

exceeds 40,000 square feet on the site. There

were a few large trees noted during our site

investigation. Specimen tree removal that may

be required will require a variance as well as

mitigation as part of any design that impacts

trees that are determined to meet specimen

tree requirements.

Recreational Site Amenities

The property has several on‐site recreational

areas located on the eastern portion. They

consist of 2 baseball fields, a grassed multi‐

purpose field, a track with multi‐purpose field

located within it, 3 long jump runways and 4

tennis courts. There is also a soft surface play

area located on the south side of the high

school.

ARCHITECTURAL

Existing Buildings

The original building was constructed in 1969,

with an addition to the Southeast side of the

building in 1986. A renovation to an original

storage building in 1998 converted the

structure to an Automotive Collision Repair lab

and classroom building. A storage building on

the West side of the building was added in 2004

for building maintenance staff. Numerous

modifications to the interior walls have been

made throughout the history of the building to

accommodate the delivery of the program to

students.

The original building is a two story structure

with the main entry at the upper level and a

grade change around the rear of the building to

at‐grade access on the lower level. An elevator

and two stair towers allow access to the lower

level. The upper level contains the

Administration, cafeteria, kitchen, health and



human services labs and classrooms and the

majority of the construction labs and

classrooms. A courtyard is located on the upper

level. The lower level contains the automotive

and biomedical labs and classrooms and the

main mechanical room. Greenhouses serving

the biomedical program are adjacent to the

lower level. The Auto body building is located

on the west side of the building at the same

elevation as the ground floor of the original

building. The 1986 addition follows the grade

on the Southeast side of the building with the

floor elevation between the first and ground

floors of the original building. Access to the

addition is via a stair tower on the North side

and a ramp on the South side. Diesel

Mechanics, HVAC, and Welding are located in

the addition.

Roof

The roof over the 1970 and 1986 portions of the

building was replaced in 2015, and is in good

condition. Roof drainage is via internal roof

drains. No overflow roof drains, as currently

required by Code, were observed in the areas

served by internal roof drains.

Exterior Wall

The exterior walls of the 1970 and the 1986

sections of building are 14” thick masonry cavity

walls consisting of 7.625” concrete block

backup, 1.5” of rigid board insulation, 1.25” air

cavity, and 3.625” brown brick veneer. Fluted

white CMU veneer is used as an accent finish.

The existing building does not make use of an

air barrier, which is recommended based on

current construction methods. Window sills are

profiled metal sills.

The overall condition of the exterior walls is fair,

however, there are numerous mortar locations

that are in poor condition and require re‐

pointing. Poor mortar joints allow water into

the wall cavity which can then migrate inside

the building, particularly without the presence

of an air barrier.

Exterior Windows and Doors

Exterior windows on the original building are

aluminum windows with single pane glazing.

The frames of these windows are not thermally

broken. Leaks have been noted at these

windows by school maintenance personnel

indicating the need for repair to the window

seals and flashing. Exterior windows in the

1986 addition are thermally broken aluminum

windows with insulated glazing (multi‐pane)

units.



Exterior entry doors are a combination of aluminum and hollow metal steel doors. At corridors and lobbies, aluminum doors within an aluminum window system are used. Exterior doors to classrooms, labs, and building service spaces are hollow metal steel doors.

Building – Interior

Floors

The main lobby and commons/ dining floor are terrazzo. This extends into some of the Academy of Health Professionals spaces where partitions have been added over time. The remaining corridors in the original building are sealed concrete. Heavy duty lab spaces have sealed concrete floors while classrooms, light duty labs (such as print production and cosmetology), and staff spaces have vinyl composition tile (VCT). The corridors in the addition are vinyl composition tile with rubber flooring on the ramp. The kitchen floor is quarry tile that is in good condition.

If a renovation option that keeps the existing building is selected, the terrazzo floors should remain and be cleaned. The vinyl tile should be replaced as part of a building wide renovation.

Partitions

Interior partitions are typically painted concrete masonry unit (CMU) if part of the original building or addition construction. Where program spaces have been modified to meet

changing program needs, drywall on metal stud or demountable metal partitions have been used. Vinyl cove based is used at all interior partition types.

Ceilings

Ceilings are a combination of acoustical lay in tiles, painted drywall, and exposed painted structure. Corridors, classrooms, and staff spaces utilize 2x4 acoustical ceiling. Toilet rooms and the kitchen utilize painted drywall. Heavy duty labs have no ceilings with roof structure being left exposed and painted.



Doors/ Hardware

Interior doors are typically wood unless located in a high abuse area that benefits from the use of hollow metal doors. Hardware has been updated so doors have a lever per current design standards for accessibility. Current school design guidelines indicate that all spaces where a student and teacher interact need to have a vision panel into the room. Several repurposed rooms do not currently satisfy this requirement and would require addition of a vision lite kit to the door.

Corridors/ Circulation

Corridors are generally accessible, of adequate width, and in good condition with the exception of the ramped corridor serving the 1986 addition. The ramps are too steep to satisfy ADA guidelines.

Toilet Rooms/Locker Rooms

Toilet rooms are too few in number based on current code requirements for quantity of plumbing fixtures of a building the size of the school. Layout of rooms does not meet ADA guidelines for clear space. Leaking has been noted by school maintenance personnel that would need to be addressed as part of a building renovation.

Locker rooms are required by multiple programs. Many programs have lockers for only one gender. Equal facilities need to be provided to both male and female students for each program. In addition, many locker areas have been located in make‐shift spaces such as existing storage closets or areas partitioned within other spaces. The girls culinary locker room, for example, is located in a corner of the dining area with partitions that were added for privacy. The male culinary locker room is located in a storage closet and has compromised privacy when the door is opened.



Casework and Equipment

Generally, the casework is stained or painted wood and is in good condition. Some spaces have added mobile or less durable storage that would not be worthy of salvage through a renovation.

Equipment is in good condition and appears to have been updated through the years as program technology needs evolve. We recommend salvaging and reusing equipment in both renovation and replacement options.

Hazardous Materials

Based on the year of construction, it is assumed that there are hazardous materials in the building construction in the form of asbestos, lead based paint, etc. The hazardous materials report maintained by CCPS will be reviewed as part of the final report.

STRUCTURAL

Existing Building Observations

Structural drawings for the original building were provided for our review, and indicate the building was designed in 1969. An addition at the east end of the building was introduced in the late 1980s, however drawings were unavailable at time of writing.

Based on our review of the documents and on‐site observations, the following is a summary of construction:

Roof Framing

Original construction consists of precast double tees, single‐stem “giant” tees, and channel slabs. Roof framing support consists of masonry bearing walls at perimeter and corridors as well as structural steel girders and columns at the commons area.

Roof framing at the addition consists of



metal deck on long‐span open web steel joists. Joists are typically supported on interior and exterior masonry bearing walls.

Floor construction in the areas bounded by lines A, F, 1, 18 and lines F, H 1, 9 consists of a 4‐inch reinforced concrete slab on composite structural steel filler beams. Filler beams are typically 24‐inches in depth spaced at 8‐feet on‐center and supported by 24‐inch structural steel girders and W8 steel columns.

Floor construction at the Ground Floor and balance of the First Floor consists of a 4‐inch concrete slab‐on‐grade, reinforced with welded wire fabric.

Exterior Walls consist of masonry veneer on concrete masonry unit back‐up.

Foundations are conventional spread footings bearing at a nominal depth.

Observations

Our walk‐thru of the existing building was for general review of the existing conditions, to the extent visible without demolition, and to gather information from maintenance personnel regarding known issues and remedial work undertaken.

Based on our walk‐thru and conversations with the building engineer, we note the following:

Façade:

Exterior veneer has varying degrees of mortar deterioration, including loose and missing mortar.

Transition from brick to fluted CMU veneer near the top of the walls appears to have been caulked (white caulk). This was observed at the interior courtyard and some portions of exterior walls.

Auto Repair Garage Bay Doors: Lintels were recently replaced to address corrosion issues, including failure of lintel at one of the bay doors.

Courtyard Leaks: Building engineer noted periodic leaks occur in the area of the courtyard to the ground floor in rain events.

Storefront: Building engineer noted ongoing leak issues at base of storefront systems, including at the north corridor between commons and classrooms, the adjacent stairwell, and courtyard.

Machine Shop: The existing slab‐on‐grade in the machine shop shows signs of settlement at the north, east and south walls of the shop. Cracking of the slab was evident, in these areas. East wall also exhibits cracking in the CMU and a gap at the slab‐on‐grade and masonry wall interface.

CMU Walls: With the exception of the Machine Shop noted above, cracking was not evident in observed interior masonry walls and interior wythes of exterior walls.

Assessment and Recommendations

Based on our observations, it is our opinion that

the existing building is structurally sound and

reuse of the existing building is feasible with

proper detailing, repairs and separation

considerations.

New addition(s) should be structurally

separated by expansion joints to

accommodate differential settlement

and mitigate the need to upgrade the

lateral load resisting system of the

existing facility.

A façade survey should be performed to

define locations, extent and scope of

façade repairs required. Local

destructive investigation may be



required to assess veneer and lintel

conditions. A contingency should be

carried in the cost estimates for

restoration of facades and lintels.

Existing machine room slab‐on‐grade

cracking should be further investigated.

This will require geotechnical sampling

in the area to assess subgrade

conditions. We would recommend a

contingency be carried to reflect

removal and replacement of the

perimeter slab‐on‐grade in the areas of

settlement.

Slab‐on‐grade upgrades: As noted

above, the existing slab‐on‐grade is a 4‐

inch slab reinforced with welded wire

fabric. Dependent on the space

program and associated equipment

required it may be necessary to remove

and replace the existing slab‐on‐grade

with heavier slab‐on‐grade

construction.

We understand there are existing geothermal

well fields in the vicinity of the existing play

fields. As‐built location and extent of the wells

should be understood prior to commencement

of design, and building footprint configured in

this area to avoid overlaying or surcharging of

the wells and associated piping. Construction in

this area will require a long run of retaining

walls to level the site for the new play fields.

Cost effective solutions for these walls may

include dry stacked modular retaining wall

systems. Final design and wall type should be

determined following geotechnical

recommendations for local and global stability.

FOOD SERVICE/KITCHEN

General Description

Carroll County Career and Technology Center’s

culinary arts program has both culinary and

pastry chef classes. These classes are held

simultaneously in the same kitchen spaces.

Class sizes are held to 22 students per

instructor.

Existing Conditions

Floor Finishes

Kitchen and serving areas are thick‐set quarry

tile with coved base. Although old, most tiles

appear in sound condition. Due to smooth

surface, tiles can be slippery when wet or laden

with grease. Floors in the dry storage are

concrete

Wall Finishes

In the kitchen, the walls are glazed tiles up to

finished ceiling and appear in good shape. In

dry storage, the walls are painted block.

Ceilings and Lighting

Ceiling heights are 10’‐0” high and exposed

throughout the kitchen, dry storage, and

serving area. Ceilings are painted and

scrubable. Twin bulb surface mounted

florescent light fixtures. Light levels throughout

the space are above the 50’ candle as required.

Assessment of Food Service Areas/Rooms

Receiving

This area has a raised deck for deliveries. To

access the kitchen for deliveries they must cross

a hallway used by the general population.

Supplies cannot be brought in on pallets with all



door sizes having standard openings. All

products are removed from the pallets and

taken by hand truck to the refrigerator/freezer

and dry storage. Refer to photos below.

Fire Protection

An Ansul system is in place. It is possible that it

may have to be updated in the future.

Dry Storage

Product is stored on 4‐tier mobile shelving

units, dunnage racks, and can racks. Walls are

painted block. Flooring is concrete. Ceiling is

painted drywall. Light levels appear sufficient.

There appears to be sufficient storage in the

space.

Walk‐in Cooler and Freezer Storage

These units are in fair condition. The unit is set

up to enter through the cooler to access the

freezer. Light is inefficient in both units. Both

units are completely filled to capacity indicating

that they are in need of more cooler and freezer

space. Refer to photos below.

Kitchen

Area is poorly ventilated for the amount of

equipment in the space. Additional cooking

equipment is needed to properly prepare

current menu items. There are (3) hand washing

sinks to cover entire kitchen space in violation

of health code. Light levels appear sufficient.

Layout for the kitchen flow is inefficient. Walls

could be removed and the area reorganized to

provide a more laborsaving workflow from

receiving, to storage, to prep, cooking, plating

serving and clean‐up. Refer to photos below.



Plating Area

The chef’s table area work flow is inefficient,

cramped and labor intensive for the number of

students in the space. Refer to photo below.

Restaurant/Classroom

Students serve the teachers in the designated

dining area. The space is separated with a

folding divider wall to create a classroom on

one side and teacher dining on the other side.

More space is recommended for both areas.

Refer to photos below.

Dishwashing

The Dish machine is fairly new. The ceiling is

painted drywall. The dirty dish table is not

configured for the best use of space. The tables

have galvanized bases that are high

maintenance and are no longer to code. Refer

to photos below.



Janitor Closet/Mop Sink

There is no mop sink in the janitor area. The

washer is oversized for the needs of the

kitchen. It is recommended to have a dedicated

soap and chemical storage space.

Hand Sinks

There are only three (3) hand sinks in the

kitchen area. Today’s health code requires a

hand sink in each section of the kitchen:

cooking, food prep, serving and dishwashing

within 15 feet. One hand sink has an eye wash

station which is no longer to code and should

be in the main cooking area with more access to

the students.

Assessment of Equipment

Exhaust Hood

Hood appears to be original to the program. It

appears in good working condition. Some of

the equipment currently in the space is not

under the hood and will need to be relocated to

comply with code. This will require a new,

expanded hood that is code compliant.

Current Cooking Equipment Inventory

(1) ‐ Double Fryer (Recommended that a dump

station is added for this piece of equipment)

(2) ‐ Double‐Stack Convection Oven (one is not

under the hood)

(1) ‐ Griddle

(1) ‐ Char‐broiler

(1) ‐ Salamander

(2) ‐ 10‐Burner ranges

(1) ‐ Steamer (Should be under the hood)

Additional Cooking Support Equipment

Floor Mixer‐60‐Gallon

Hot Food Wells‐4 Wells‐1 each

Reach‐In Cooler‐2 each

Double door Reach‐In Cooler‐1 each



Mobile Heated Cabinets‐1 each

Pan Rack‐2 each

Prep Sink,

Pot Sink

Baker’s Table

Scales‐3 each

Walk‐In Cooler/Freezer

4 Compartment Hot Food Chef’s Table

Ansul System

Worktable with Sink

Coffee Makers

Hood

Ice Machine

5‐gallon Mixers‐5 each

Slicer

Heated Proofer Cabinet

Worktables‐10 Stainless Steel, 5

Butcher Block

Utility Cart‐1 each

Baker Storage Bins

Hand Sinks‐3 each

Shelving

Storage Cage

Washer & Dryer

Beverage Counter with Sink

Most of the equipment appears to be in fair to

good working condition.

Recommendations

The cooler/freezer is undersized for the

class needs. Consider increasing the

size of the cooler/freezer with a more

efficient separate system.

Install a demonstration kitchen with

induction cooking, under‐counter

refrigeration, and display mirror with

TV/video screens to provide more

extended student access to the

instructor.

It is recommended that knife storage is

placed in a secured cabinet.

Expansion of the beverage station is

recommended to properly address how

stations flow during usage. Possibly

include an ice tea dispenser.

Conclusions

With the current number of students in the

program the space is overcrowded. Pastry

students and culinary students constantly cross

paths while accessing the cooking and pastry



equipment which is used by both programs.

With the possibility of expanding the programs

the kitchen will need to be enlarged to

accommodate both programs. The majority of

the equipment is reusable with various life

spans per each piece. Additional cooking

equipment recommendations would include a

tilting skillet, a combi‐oven, induction cookers

and a pastry deck oven. Reconfigure overall

kitchen cooking, prepping and serving areas to

better maximize space. The wall between the

kitchen and pot sink area could be removed if it

is not structural, then the kitchen can be

reconfigured to create additional space for the

current program. If expansion of the programs

is in the future, additional square footage will

be required.

MECHANICAL

EXISTING MECHANICAL CONDITIONS

General

The existing mechanical systems, for the most

part, are original to the time of construction, be

it the 1969 building or the 1986 Addition. The

Auto Collision Shop, which was relocated in

1998, into the renovated Storage Building, has

new HVAC and plumbing systems and

equipment. Similarly, the Masonry Shop and

Carpentry Shop HVAC Systems were upgraded

to help alleviate indoor air quality concerns.

The existing cooling tower, chiller, domestic hot

water heater(s), greenhouse systems, and shop

air compressors have been replaced as part of

independent systemic projects over the years.

Supplemental split type direct expansion

systems have been sporadically added

throughout the building.

There have been several modifications to the

spaces and/or their function with little to no

modifications to the mechanical system.

Heating

The original and primary heating source for the

building is electric resistance. Carroll County

Public Schools, in conjunction with BGE, ran a

new four‐inch (4”) two‐pound (2 psig) gas main

into a small mechanical room at the northwest

end of the building which also houses the

domestic hot water heaters. Currently, this gas

service does supply the domestic hot water

heaters, greenhouse units, carpentry and

masonry shops make‐up air units, collision shop

rooftop unit, collision shop classroom rooftop

unit, and the paint spray booth heater.

Currently, a 3‐inch valved and capped

connection exists in the water heater

mechanical room for future extension. A valved

and capped connection was also provided for

the emergency generator; however, at this

time, the unit has not been converted from LP

to natural gas. A gas line has been extended to

the Lower Level Electrical Room for connection

to the emergency generator, which currently

remains propane‐fired.

Cooling

The building is partially air‐conditioned. Labs,

such as Diesel, Welding, HVAC, Automotive

Mechanics, Masonry, and Carpentry Labs are

heated and ventilated only. Classrooms are

typically cooled. Chilled water is generated by a

water‐cooled chiller located in the Lower

Level/Ground Floor Mechanical Equipment

Room which serves the original building only.

Split type Dx units serve the 1986 Addition

classrooms as well as various spaces within the

original building.



The chiller, manufactured by York International

(Model #VCWJ77KHO‐46PA; Serial# SMEM‐

569940) was installed in 1997, utilizes

refrigerant R‐22, has 181 nominal ton capacity,

has two (2) semi‐hermetic reciprocating

compressors, and operates at a flow rate of 436

gallons per minute (gpm). A new Spirotherm air

and dirt separator has recently been installed in

the chilled water system. Two (2) base‐

mounted end suction pumps, one (1) standby;

circulate chilled water through steel pipe mains

to unit ventilators which serve individual

spaces.

A forced draft, centrifugal type open cooling

tower is located at the northwest end of the

building. It has a nominal capacity of 116 tons.

The unit is fairly new and is manufactured by

Baltimore Air Coil Company (BAC Model

Number VTO‐116M). Condenser water pipes

between the building and cooling tower are

located below‐grade. A remote sump tank is

located in the Lower Level/Ground Floor

Mechanical Equipment Room, which houses the

chiller and multiple shop air compressors. Two

(2) base‐mounted end suction pumps, one (1)

standby, circulate condenser water to the

water‐cooled chiller.

Compressed Air

A new (2003/2004) Ingersoll Rand air

compressor and refrigerated air dryer has been

installed for the shops. The existing air

compressors/tanks are used for back‐

up/redundancy. These air compressors, dryers,

and tanks are located in the Lower

Level/Ground Floor Mechanical Equipment

Room, which is shared with the chiller and

cooling plant equipment.

Individual Space Condition – 1986 Addition

The HVAC and Diesel Shops utilize roof‐

mounted heating and ventilating units equipped

with electric resistance heating coils (42 kW

HVAC Shop/78kW Diesel Shop). These shops

have exposed ductwork, a roof‐mounted gravity

relief air hood, space exhaust fan and ceiling

fans. The Diesel Shop has multiple dedicated

local exhaust systems. The Classroom areas are

equipped with a residential type split fan coil

unit with electric heat and remote air‐cooled

condensing unit. Outside air is provided

through a gravity intake vent connected to the

return air duct. Independent exhaust fans serve

the toilet and locker room areas.

The Welding Shop utilizes two (2) roof‐mounted

heat recovery units equipped with 57 kW

electric heat coils. Heat recovery units contain

both a supply fan and exhaust fan. The exhaust

system connects to multiple welding booth

canopy hoods and local source capture work

bench inlets. The classroom is served with a

residential type split fan coil unit with electric

heat and remote air‐cooled condensing unit.

Outside air is provided through a gravity intake

vent connected to the return air duct. An

independent exhaust fan serves the toilet room

and locker room area.

The Conference room is served with a

residential type split fan coil unit with electric

heat and remote air‐cooled condensing unit.

Outside air is provided through a gravity intake

vent connected to the return air duct. An

independent exhaust fan serves the toilet room

and locker room area.

Electric heaters are located at the entryways

and in the corridor.



Individual Space Condition – Original

Building

Greenhouse

The Greenhouse system has been recently

upgraded, including new gas‐fired heating units,

circulation fans, motorized windows, water

spray system, and “microgrow” greenhouse

control system.

Horticulture (now Biomedical)

A split A/C unit currently serves the Biomedical

Computer Lab. A heating and ventilating unit

ventilator currently serves the Biomedical Lab.

A fume hood was recently installed with an

exhaust fan tied into the existing Collision

Repair Shop Paint Booth Exhaust Fan/Duct

System. The Biomedical Shop is currently

located where the existing Paint Spray Booth

was located.

Auto Shop Labs

The main incoming fire service is located in the

old Collision Shop Area (New Auto

Transportation Area). A large heating and

ventilating unit (96 kW heating coil) serves the

old Collision Repair Shop and is hung in the

associated Storage Room. Similarly, a large

heating and ventilating unit (50 kW heating coil)

located over the same Storage Area is one of

two (2) units that serve the Auto Mechanics

Lab. The second unit (60 kW) is located over

the adjacent gang toilet rooms at the Southeast

end of the Lower Level. The common classroom

is served by a horizontal/above‐ceiling heating

and ventilating unit ventilator. This unit

ventilator and the two (2) heating and

ventilating units located above the Storage

Room have outside air ducted to an areaway

located in the Courtyard at the Main Level.

Both shops have independent exhaust systems

and the Auto Transportation Area still has local

dust filtration units originally utilized for the

Collision Repair Shop.

Collision Repair Shop

The Collision Repair Shop was previously

relocated to the existing Storage Building, which

is adjacent to the Main Building, Lower Level,

Northeast side. The classroom is served by a

dedicated roof‐mounted packaged air handling

unit with gas‐fired furnace. The Collision Repair

Lab is served by an independent roof‐mounted,

gas‐fired heating and ventilating unit. A new

Paint Spray Booth is located at the Southeast

end of the building and its associated air

exchange heater unit (gas‐fired) is located

outside at grade.

Lower Level Corridor

Relief air from the labs is ducted into the

corridor where a separate intake grille is

connected to a vertical duct up to a roof

exhaust fan. This is currently a Code Violation.

Electric unit heaters are located in the corridor

and stair towers.

Upper Level East Labs (Electrical, Career

Assessment, Physical Rehab., Cosmetology)

These Labs are located on the Northeast side of

the building over the Lower Level

Lab/Classroom spaces and look out over the

new Collision Shop. These spaces are served by

both horizontal (above‐ceiling) and vertical

(floor‐mounted) type unit ventilators. All

spaces except for the Electrical Lab are cooled

and served by the central chilled water plant.

Vertical units have through‐the‐wall intake

vents for fresh air, while the above‐ceiling types

are ducted to roof‐mounted fresh air intake

vents. This air is then relieved to the corridor,



where a roof‐mounted exhaust fan draws the

air through the corridor and relieves it to the

outside.

Due to the odors generated in the Cosmetology

Lab, two (2) heat recovery units were installed

above the ceiling to provide additional fresh air

to the space and dilute/exhaust odors primarily

created by chemicals used in permanent‐wave

solutions.

Carpentry Lab

The Carpentry and Masonry Labs have switched

from the originally intended locations. Other

modifications have also occurred. A new gas‐

fired rooftop heating and ventilating unit was

installed to provide make‐up air to the space as

the original heating and ventilating unit were

already removed. Electric unit heaters provided

the space with heat and are now used to

supplement the heat provided by the make‐up

air system. The dust collector is original and is

still functioning; however, the dust collection

system was recently replaced. A horizontal

heating and cooling unit ventilator serves both

the Carpentry and Masonry Lab Classrooms.

Masonry Lab

The Masonry Shop, similar to the Carpentry

Shop, was recently upgraded with a roof‐

mounted gas‐fired heating and ventilating unit.

New supply and return air ductwork is tied into

the new rooftop unit. The air distribution

system was designed as a push‐pull system

supplying (pushed) clean air at the corridor end

of the space which is then returned (pulled) at

the exterior wall through a filter return grille. A

dust type collector connected to a canopy hood

located over the mixing area was installed to

capture particulate matter during the mixing

process.

Engineering Lab

Two (2) split Sanyo type (ductless mini‐split

system) units and the existing horizontal

heating and ventilating unit ventilator serve the

space.

Manufacturing & Machine Tech. Lab

The Machine Shop is served by a horizontal

heating and ventilating unit ventilator and the

classroom is served by a split fan coil unit with

remote heat pump.

Computer Resource Center (CRC) Lab

An independent ductless split unit by EMI

Technologies serves this space, which originally,

was part of the Main Lobby. An electric cabinet

heater is located within the room.

Textiles and Fashion Design Lab

A split fan coil unit by Trane serves the area.

The remote heat pump is located on the roof.

Two (2) above‐ceiling unit ventilators with

cooling serve the classroom space.

CADD Classroom/Lab

Two (2) vertical (floor‐mounted) unit ventilators

with cooling serve the space.

Video Print Production Room

Two (2) above‐ceiling horizontal style units and

one (1) floor‐mounted vertical style unit

ventilator with cooling serve the space.

Computer Technology Lab/Classroom

An above‐ceiling unit ventilator with cooling

serves the classroom, while a floor‐mounted

split fan‐coil unit, with roof‐mounted heat

pump serves the Tech Lab through an overhead

distribution system.



Academy of Health Lab Suite

The Academy of Health Suite was originally a

resource center and connecting corridor, both

of which extended from corridor to corridor.

Above‐ceiling unit ventilators were located

above the northeast corridor ceiling and

relieved to the corridor at the southeast

corridor. The current layout creates multiple

spaces within this area, yet only minor changes

to the HVAC System occurred. Health Suite 101

is currently served by a ductless split system.

Commons Area/Student Dining

The Commons Area is an open space served by

six (6) horizontal unit ventilators with cooling

coils. Outside air is introduced into the units

from roof‐mounted gravity vents.

Kitchen/Culinary Arts Lab

Similar to the Commons Area, three (3)

horizontal unit ventilators with cooling coils

serve the space. Outside air is introduced into

the units from roof‐mounted gravity vents.

Roof‐mounted exhaust fans serve the kitchen

hoods and a roof‐mounted tempering unit (108

kW electric heater) provides supplemental

make‐up air for the kitchen hood exhaust

requirements.

Culinary Dining Room (“Restaurant”) and

Classroom

Floor‐mounted heating and cooling unit

ventilators serve these areas.

Office/Administration Suite

A small above‐ceiling self‐contained heating‐

cooling unit serves the interior staff area, while

floor‐mounted heating‐cooling fan coil units

serve the perimeter office space.

Lobby

The Lobby is heated and cooled by horizontal

flush‐mounted recirculating air type unit

ventilators supplemented by cabinet unit

heaters at the entry door.

Evaluation

The existing rooftop units and heat recovery

units serving the 1986 Addition are not

functioning and/or not functioning properly.

The rooftop heating and ventilating units were

manufactured by Bohn, which is no longer in

business. Similarly, the heat recovery units

were manufactured by “Temp Exchanger”,

which also is no longer in business. All of the

equipment, including the split systems, are

beyond their useful lives and are recommended

to be replaced.

The existing chilled water piping systems are

degrading and have caused the need to keep

the chilled water system circulating 24/7,

including throughout the entire heating season

when chilled water is not required. A Spirovent

air and dirt separator has been installed to aid

in cleaning the system. It is our understanding

that the chiller ices up, which is probably the

result of fouling of the evaporator tubes.

Ultimately, it is recommended that the chiller,

piping, cooling tower, remote sump, and all

associated pumps be replaced.

The existing heating system, for the most part,

remains as electric resistance. Even though

electric resistance is 100% efficient, it is

typically more expensive to operate. The

electric heaters are located in equipment (unit

ventilators, fan‐coil units, rooftop units, wall

heaters) that is typically original to the time of

construction. This equipment is beyond its

useful life and is recommended to be replaced.



Based on the age of the terminal unit

equipment, controls, ongoing indoor air quality,

and thermal comfort issues, age and type of

equipment, it is recommended that the HVAC

System and associated electric resistance

heating units be replaced in their entirety. The

existing relief air system uses the corridor as a

duct, which is a Code violation that needs to be

corrected. Most storage rooms have individual

exhaust fans. There are many special system

exhaust fans, as well as relief air system exhaust

fans, which are original and beyond their useful

lives. It is recommended that all exhaust fans

and special exhaust systems be replaced in their

entirety.

ELECTRICAL

Electrical Service and Distribution System

The existing electrical service is the original

main switchboard consisting of a 3000 Amp,

277/480 volt, three phase, 4‐wire service. The

existing medium voltage transformer is located

near the Greenhouse at the rear of the building.

BGE provides primary electric service to the

site. The primary BGE feeder serves both

Westminster High School and the Career and

Technology Center. A maximum load of the

meter serving the School is 2852 kW, which

indicates that the existing switchboard cannot

serve the new loads. In order to serve the new

HVAC loads and future loads, as well as to

provide for capacity for the new classrooms, the

electrical service will be served from a new

switchboard and will back feed the existing

switchboard. The utility transformer will need

to be replaced with a larger transformer.

Emergency power is provided by a propane

generator located in a room next to the Main

Electric Room. The generator serves the

emergency incandescent lights in the stairs.

Lighting

Most of the existing corridors use 1' x 4'

surface‐mounted 1‐lamp fixtures. Key switches

are used to control the corridor lights. Exit

signs use green letters.

Fire Alarm System

The existing Fire Alarm System serving the

building is a combination of the original Simplex

Fire Alarm System and a recently‐installed

Edwards EST2 fire alarm panel, located in the

Main Electric Room. The Fire Alarm System

uses horns and strobes located throughout the

school to provide audible and visual alarms. A

Communicator Panel provides dialup

communications with the UL Monitoring

Service.

Security System

The existing Ademco Security System located in

the Health Suite protects the school using a

combination of door contacts and motion

detectors. The System uses keypads located

throughout the school to arm and disarm the

alarm. A Communicator Panel provides dial‐up

communications with the UL Monitoring

Service. The existing Security System is at its

maximum capacity and will need to be

expanded or replaced.

Closed Circuit Television (CCTV) Security

Camera System

Currently, the school uses fifteen (15) security

cameras connected to a time‐lapse VCR located

in the Principal’s Office in the Main Office.



Access Control System

Currently, the school uses a BEST Access

Control/ Card Reader System.

Video Network Cable Television System

A coaxial video cabling system is provided throughout the school. The video system is powered by a BIDA video amplifier, in the existing Media Retrieval System, located in the Main Office.

Master Clocks

Existing Master Clocks are connected to the

existing Master Clock / Bell System. A Rauland

Time Control unit located in the Main Office

provides control of the Master Clock System.

Voice Network – Telephone / Paging /

Intercom System

The incoming telephone service is a 50‐pair

cable terminating in the Generator Room, next

to the Main Electric Room. The existing Rauland

Telecenter Public Address Cabinet, located in

the Main Office, will be reused and expanded as

needed. The Telecenter System is in good

condition and has capacity to service the new

additions. The existing PA System uses ceiling‐

mounted speakers and call switch. The existing

Northern Telecom Norstar Meridian telephone

switch in the Storage Room will be re‐used.

Data Network

Currently, there exists one (1) MDF (Main

Office). The MDF contains multiple 48 port

patch panels. Category 5 data cabling, installed

around 1999, is provided throughout the

school. Five (5) IDF Rooms exist:

1. Computer Technology

2. Video/Graphic Production

3. Drafting B111

4. Tech Support & Networking

5. Collision Repair Classroom

Life Safety Code Issues:

Carroll County Career and Technology Center complied with the building codes enacted at the

time of original construction and the 1986 addition. However, the school is not compliant with

current codes. Renovation of the existing building will require the following items be addressed

to meet current code requirements.

Interior doors contain louvers which allow the passage of smoke. Note that this change

will require modifications to the HVAC system to bring the building into code

compliance.

Elevator located within stair tower which is not allowed by code

Stair towers are not fully enclosed with rated construction.

Storage for culinary program in egress corridor.

Code Analysis ǀ 06


Accessibility:

The school does not have the required number of accessible lockers.

Many doors do not have the required access space to approach the push or the pull side of the door.

PROPOSED DESIGN OPTIONS

Proposed Design Options ǀ 07


DESIGN GOALS

The Study Team refined four proposed design concepts to provide CCPS with a range of options that best serve Carroll County Public Schools, Carroll County Career and Technology Center faculty and staff, and the Community’s best interest. This section presents the four proposed plan options in order of increasing degree of architectural intervention. Key advantages and disadvantages are listed for each option along with a corresponding scope of work. The section concludes with a discussion of mechanical and electrical recommendations that are applicable to all four options. All of the options proposed herein have been taken into consideration in the development of the cost estimate presented in section 08.

Option A ‐ Partial Modernization

Addresses the wait list needs of the school with a building addition and renovates the existing building without additional expansion. Existing walls remain in place, limiting program accommodation. Existing relocatable classrooms remain.

Modernizes/replaces all major building systems to ensure compliance with all current building, life safety, energy, and accessibility code requirements.

Improves the interior environmental quality level and educational experience by providing improved comfort systems, and new finishes. Natural light is added in limited areas of the existing building where possible.

Option B ‐ Modernization

Renovates and expands the existing building with 5 additions to accommodate the proposed program with improved adjacencies between program elements. Existing walls are relocated as needed to accommodate the requirements of the program.

Provides a facility that addresses the requirements of the proposed educational program (including wait list) and will support 21st century learning environments.

Modernizes/replaces all major building systems to ensure compliance with all current building, life safety, energy, and accessibility code requirements.

Improves the interior environmental quality level and educational experience by providing natural light, improved comfort systems, and new finishes.



Option C ‐ Replacement on Existing Campus

Creates a replacement building on the existing campus to accommodate the proposed program (including wait list) with improved adjacencies between program elements.

Reduced scope of additions and renovations.

Provides new building systems to ensure compliance with all current building, life safety, energy, and accessibility code requirements.


Provides new play fields for Westminster High School on the site of the existing building.

Provides a new Community Media Center adjacent to the school for shared use.

Option D ‐ Replacement on an Undeveloped Site

Provides a facility that addresses the requirements of the proposed educational program and will support 21st century learning environments.

Provides new building systems to ensure compliance with all current building, life safety, energy, and accessibility code requirements.


Alternative Sites

As part of the design option review process, CCPS directed HCM to review the viability of locating portions of CCCTC programs at existing CCPS facilities. HCM reviewed potential spaces at Westminster High School, South Carroll High School, and North Carroll High School. In each case, space could be utilized to reduce the size of the required additions or size of a replacement facility. However, renovation costs would be required at similar $/SF capital renovation costs as required to renovate the existing facility to accommodate the relocation of the programs to these spaces. Operational costs (i.e. transportation costs, additional staffing, utility costs, etc.) also will need to be accounted for and will vary significantly between currently occupied facilities and buildings that are not currently in use. Refer to Appendix A for a cost breakdown of work typical for renovation at Westminster High School if some programs are relocated as an example. The proposed options do not take relocation of programs to other sites into account for purposes of this study.



Option A: Partial Modernization

Partial Modernization (Option A) includes constructing a 21,000 sf addition that contains spaces for the wait list programs indicated in the program inventory space summary. Proposed work also includes complete renovation of the existing building to bring the entire building into conformance with current building and life safety codes. Enlargement of program space within the existing building is not provided as part of this partial modernization, and life safety renovations may reduce the existing instruction space to accommodate the modifications. Relocatable classrooms will remain during and after completion of the partial modernization. Maintaining building occupancy and operation will require a multi‐phase construction process.

Advantages:

Disadvantages:

Building:

Full building program is not addressed, leaving programs with inadequate space by current design standards.

Shape, location, and quality of spaces to be renovated in place is limited by working within the existing building footprint.

Least energy efficient option.

Adjacencies of programs by cluster is not addressed.

Exterior of building is not updated, so there is limited opportunity to see where the money is being spent.



Several learning spaces are detached from school building as relocatable classrooms and detached collision repair building will remain.

Longest construction duration of four options due to renovation of spaces in place in small phases.

Higher phasing costs due to multiple phases required.

Longer impact on school operations.

Access to the loading dock for culinary and food service deliveries is not adequate (existing relocatable classroom blocks access).

Access to public retail spaces (cosmetology, culinary, textiles/fashion) is poor.

Dining commons is undersized to accommodate increased student population.

Potential for programs to be taken off‐line during construction period based on phasing, amount of time needed to renovate the particular space, and the difficulty of relocating programs to temporary space.

Building 35 Year Life Cycle Costs

MEP SYSTEMS

Addition/ Renovation Options (Options A and B):

Under the addition/ renovation building options, all existing mechanical systems will be replaced in their

entirety. The conventional 4‐pipe heating and cooling system includes a new central heating and cooling plant

served by boilers and air cooled chillers. An alternate approach is to provide a hybrid geothermal system which

utilizes the earth as its heat exchanger and requires a smaller central plant. The existing building and associated

building envelope will be less efficient as compared to a new building. Therefore, the mechanical systems will be

less efficient since these existing physical condition limitations will increase energy consumption by mechanical

equipment, thus lowering the energy efficiency of the renovation/ addition option when compared to the new

building option.

New Building Option (Options C and D):

Under the new building option, conventional 4‐pipe and geothermal are analyzed.

Mechanical Life Cycle Costs:

Annual energy costs were developed utilizing computer modeling for both the new building option and the

renovation/ addition options. The annual operating and maintenance costs were then multiplied by 35 years to

provide a cost analysis for a 35 year life span. In addition, a 5 percent assumed interest rate and mechanical

construction costs are included in the life cycle cost calculation. A conventional 4‐pipe heating and cooling

system was analyzed for all building options.

Building Maintenance Life Cycle Costs:

The building maintenance/ replacement costs are the costs to maintain and replace windows, roofs, floor tile,

paint, carpet, ceramic tile, casework, ceiling tile, doors, window blinds, kitchen equipment, etc. as required over

the 35 year period. This does not include mechanical costs that are included above. Some of these materials will

have a longer life span than others and that estimated useful life was factored into the calculation for

replacement.
