STATEMENT OF WORK

DES-FD705-7J

Repair Vehicle Exhaust Ventilation System Bldg. 4390 Fire Station #2

31 Aug 2018

1. GENERAL: The project is to remove existing fire apparatus vehicle exhaust filtration system and provide a fire apparatus vehicle exhaust removal system (FAVERS). This will eliminate the occurrence of air contaminants to all areas of the building caused by operation of the fire apparatus vehicles inside apparatus bay in lieu of ‘filtering’ the contaminates. Since the standard operating procedure for vehicle start-up is to open the bay doors before operating the vehicles, this work will not have any impact to the existing HVAC system.
