ADA & BUILDINGCODE


14

IDENTITY & CONTEXT• The first impression of the site and building is

the large parking loop which dominates the view

• The single story design is compatible with the surrounding residential neighborhood but does not establish an appropriate civic presence

• The building entrance lacks a sense of identity

• The configuration of the building does not create positive external spaces

• The site lacks adequate public space in front of the building which would make a welcoming approach to the school

EXISTINGDESIGN / LAYOUT


15



• The original building construction was completed in ~1970

• Approximately 54,178 square feet

• Single story structure

• Two main classroom wings

PUBLIC ZONEPRIVATE ZONE

17

• The 1968 as-built existing building drawings appear to accurately reflect the construction

24”-36” deep Glulam beams spaced 9-11 ft. o.c. spanning from exterior to corridor bearing walls. 3x6 T&G roof decking

Shallow spread footing foundations

• There was some water damage visible to the roof deck in the mechanical equipment room

• Overall the condition of the structure is sound

No major cracking or splitting of the wood members

Masonry appears sound

The exterior storage area site wall has multiple cracks and needs repairs

• The structure cannot support a second floor -additions can be adjacent to the building or demo a portion of the existing building to build a multi-story structure

• In general the mechanical systems serving the building are in fair to poor condition and at the end of their expected useful life

• The chiller is in fair condition – even with proper maintenance, the chiller is nearing the end of its expected useful life

• The boiler sections are original to the building and are in fair condition

• The existing domestic water heater is a storage tank type with a heating water heat exchanger

• The boilers provide heating water to the exchanger. The tank is in poor condition and in need of replacement

• The building dual temperature loop, domestic water and condenser water is served by a series of pumps – some pumps are original to the building and in poor condition

• Pumps replaced as part of the maintenance program are in fair condition

• An incoming water service enters the building at the main mechanical room

• The service splits to a domestic water service and fire sprinkler service

• The only space in the building protected by a fire sprinkler system is the main mechanical room

• Low pressure natural gas main enters the building at the main mechanical room

• Automatic Temperature Controls are served by a pneumatic control system located in the main mechanical room
