7.8 EQUIPMENT LOCATION AND INSTALLATION
A. GENERAL:
Equipment shall be located to be accessible for
installation, operation and repair.
Mechanical spaces shall be of
suitable size to permit inspection and access for maintenance, and to
provide space for future equipment when required.
The effect that
equipment noise or vibration might have on areas adjacent to, above,
and below equipment shall be considered.
Location of equipment
remote from sound sensitive areas should be emphasized.
Design shall
comply with specified room sound ratings.
B. HVAC EQUIPMENT: Air handling units and similar equipment shall be
housed in a mechanical equipment room or in a mechanical penthouse
building.
Penthouse type of fully weatherized roof top units
constructed in standard sections of modules would be acceptable in
lieu of the mechanical equipment rooms or mechanical penthouses.
These units shall provide excess sections for walk through servicing,
maintenance, and shall ensure that the piping connections and
electrical conduits are fully enclosed within the units.
The
designer shall ensure close coordination with the architecture and
structural disciplines for issues, such as, aesthetics, operating
weight, shaft locations, etc., while selecting the roof top
units.
C. COORDINATION:
Coordinate and make provisions for all necessary
stairs, cat walks, platforms, steps over roof mounted piping and
ducts, etc., that will be required for access, operation and
maintenance. Access to roofs by portable ladder is not acceptable.
D. COOLING TOWERS: Select and locate cooling towers to avoid problems
with esthetics, noise, vibrations, air recirculations or drift.
