between ceilings and the structure above. This
condition occurred on the first floor above Autopsy
Room 122 and Office Room 108, and on the second floor
above Drug Lab Room 210, Instrument Lab Room 226,
Corridor 202 , and Corridor 206 . Drawings were issued
by the design consultants revising the size and
location of the mechanical ductwork to eliminate this
problem.

B.' The Uniform Mechanical Code requires that boiler rooms
be provided with ventilation for combustion air, low
near the floor and high near the ceiling. The original
working drawings show louvers in the exterior wall for
the "low" ventilation but do not provide for "high"
ventilation. Consequently, a combustion air shaft must
be added to provide the required ventilation.
