Proposed System(s):
The building has an existing 6" fire service water entrance, downsized to a 4" fire service after entering the building, at the West
mechanical closet. All underground and all associated fire suppression piping and fire hose cabinets shall be demolished. The 4"
fire service shall be demolished within the West mechanical closet, back to the 6" fire service entrance. The 6" fire entrance
located at the West mechanical closet shall remain and additional zones shall be added to cover areas of new work and renovation
where fire sprinkler system does not currently exist. Existing sprinkler coverage of the existing building shall remain, and sprinkler
heads and branch piping shall be relocated as required to conform to new floor plans. The overall sprinkler system will consist of
the following components:
1. Existing exterior post indicator valve.
2. New double check detector assembly (DCDA) with flow switches and tamper/supervisory valves.
3. Existing exterior Siamese fire department connection (FDC).
4. New exterior alarm device in the event a flow switch is activated.
5. New individual zone valves with supervisory switches and drain valves.
The sprinkler main will be sized for light hazard occupancy. The maximum coverage area for any single sprinkler zone is 52,000
square feet. Due to the overall size of the building, the wet sprinkler system will be divided into three (3) wet sprinkler zones for
interior spaces. There are no dry sprinkler zones anticipated for this project.
A single-interlock preaction fire sprinkler system shall be provided to protect the SCC room. The preaction system shall be
supervised and arranged so that water is not introduced into the piping until both detection system activation and sprinkler head
operation occur in accordance with NFPA 13 and NFPA 72 requirements. Detection devices within the room shall initiate the
opening of the preaction valve upon confirmed fire conditions.
The sprinklers in the spaces with acoustical ceiling tile will be concealed type sprinkler heads, with ordinary temperature sprinkler
heads. All sprinkler heads in exposed areas will be upright type. Sprinklers shall be coordinated with architect based on ceiling type
and owner preference.
Wet sprinkler piping (2"and smaller) shall be Schedule 40 black steel with threaded fittings. Wet sprinkler piping (2-1/2" and
larger) shall be Schedule 10 black steel with flanged or grooved fittings.

Division 23 Mechanical
Proposed System(s):
Air Side Systems
Existing RTU-1
* The existing building is served by an existing Daikin multi-zone VAV rooftop unit (MZVAV RTU)
with direct expansion (DX) cooling and indirect gas-fired heating. This unit will remain in place. The
unit was installed in 2018 and is less than halfway through its expected life.
* All existing variable air volume (VAV) terminal units will be removed and replaced with new units to
accommodate the new building programming. The existing boiler plant equipment and heating water
piping will be removed. The new VAVs will be served by the new boiler plant located in the new
addition, and new heating water piping will be provided. The existing ductwork may be reused where
practical.
RTU-2
* A small new gas/DX MZVAV RTU will be provided to serve the workstations and offices in the
southeast corner of the existing building (existing board room location). Serving this area from a
dedicated unit will allow the existing unit to accommodate the increased occupant load of the new
building programming. The basis of design is a Daikin Rebel, which has double wall cabinet
construction.
AHU-1
* The seminar room at the northwest corner of the addition will be served by a dedicated single-zone
VAV air handling unit (SZVAV AHU). The AHU will be located in the mechanical mezzanine. The
AHU will have double wall cabinet construction, variable speed supply fan(s), variable speed exhaust
fan(s), economizer, hydronic cooling coils, and a hydronic heating coil. The basis of design is Daikin.
AHU-2
* The portion of the new addition west of the welcome center (except for the seminar room) will be
served by a MZVAV AHU. The AHU will be located in the mechanical mezzanine. The AHU will
have double wall cabinet construction, variable speed supply fan(s), variable speed return fan(s),
economizer, hydronic cooling coils, and a hydronic heating coil. The basis of design is Daikin.
AHU-3
* The portion of the new addition east of the welcome center will be served by a MZVAV AHU similar
to AHU-2. The AHU will be located in the mechanical room on the upper level.
Areas served by multi-zone units (RTU-2, AHU-2 and AHU-3) will be zoned to provide independent
temperature control for different spaces. Each zone will be served by a VAV terminal unit with a hydronic
reheat coil and a dedicated thermostat. The basis of design is Titus. Zoning and thermostat locations will follow
the diagram previously reviewed and approved by the district.
Rooftop exhaust fans will serve restrooms and kitchen areas. The basis of design is Greenheck.
Ductless split cooling/heating systems will serve electrical, data, and A/V rooms. Air-cooled condensing units
will be located on the roof. The basis of design is Daikin.
A ductless split cooling/heating system will provide backup conditioning for the Security Control Center in the
event of a power outage. The air-cooled condensing unit will be located on the roof. The basis of design is
Daikin. The system will be backed up by the generator and enabled/disabled by a wall switch.

is not planned. The chiller will be a packaged air-cooled scroll unit. The basis of design is Daikin.
* The system fluid will be 35% propylene glycol to provide burst protection for the outdoor piping
without the need for winterization. The chiller will not be required to run in the winter as all AHUs
will be capable of cooling with economizer at temperatures below 55 F.
