Upgrade Ventilation System - SSR - Division 01 - General Work

This project involves the replacement of existing ventilation system located in the penthouse mechanical room of Building 951 located at 809 S Damen Ave, Chicago, IL 60612 with a new ventilation system. The existing ventilation system comprises of (2) supply air units, (2) kitchen exhaust fans, (2) toilet exhaust fans, and an associated heat recovery system. We’ll be replacing the existing ventilation system with (1) supply air unit, (1) kitchen exhaust fan, (1) toilet exhaust fan and a heat pipe energy recovery system. The supply air provides corridor make-up for the north and south tower while the exhaust fans serve 251 resident units in both the towers. The scope of the project involves replacement of all the existing mechanical piping risers in the penthouse mechanical room with new and relocation of some of the other existing utilities in the mechanical room to accommodate the new work. The penthouse mechanical room floor is not structurally suitable to house the new ventilation system and for this reason, we’ll be mounting all the new equipment on a structural beam tied to the columns of this building. Refer to the structural drawings for the nature of the scope. This project also involves the replacement of existing change over valves, as well as other valves associated with the two-pipe system in the lower-level mechanical room with new valves as indicated on the mechanical drawings.
