During review of the plans for the above noted project, it was found that the following information,
clarifications or changes are needed. Please provide written responses as to where the changes can
be found on the plans, and submit revised plans/documents to Marie Harrison, Senior Permit
Coordinator. Thank you.
1.Please provide a detail or description of the roof/ceiling construction in order to evaluate the
need for fire dampers. It appears that there needs to be fire dampers where ductwork
penetrates the ceiling of the fire-rated roof/ceiling assembly according to IBC 716.6.2.
2.Indicate a smoke damper in the return air duct in accordance with IMC 606.2.1 unless the
area is protected by area smoke detectors connected to a fire alarm system. If this exception
is taken, please note on the plans.
3.Indicate on the plans the efficiency ratings (COP and IPLV) for the new equipment. This
must comply with WSEC Table 14-1C.
4.Indicate the thickness of insulation for the chiller lines. WSEC Table 14-6
