About this file
This is a Scope of Work document for a National Park Service construction project at Lowell National Historical Park involving the replacement of cooling tower and mechanical equipment at Boott Cotton Mill #6 in downtown Lowell, Massachusetts.
The base scope (PMIS 337427A & C) requires removal of the existing rooftop cooling tower from the fifth floor via crane and installation of a new low-rise cooling tower on vibration rails with roof-level piping connections. The project includes replacing one 384 gpm 90-foot head condenser pump and one 500 gpm 70-foot head circulatory pump in the basement mechanical room, with variable frequency drives added to both pumps. Additional work encompasses replacing four two-way control valves, sixteen ball valves, one automatic control valve, four butterfly valves, approximately 16 linear feet of pipe and connections, three sets of vibration springs with concrete pad mounting, and programming the cooling tower and pumps to the Trane Building Management System. Electrical work shall include new conduit and wiring as necessary.
Option #1 provides for replacement of one circulatory pump in an adjacent building's basement mechanical room with a variable frequency drive, including replacement of two two-way control valves, eight ball valves, one automatic control valve, two butterfly valves, approximately 8 linear feet of pipe and connections, one set of vibration springs with existing concrete pad mounting, and programming to the Trane Building Management System. Complete specifications and detailed plans are referenced in the contract documents.

Replace Cooling Tower #1, Condenser and Circulator Pumps, and
Associated Valves at Boott Cotton Mill #6
Scope of Work
This work is for a cooling tower replacement (PMIS 337427A) on the roof of the fifth floor of the Boott Cotton Mill #6, in downtown Lowell, MA. The project involves removing the existing rooftop cooling tower by crane (placed at the adjacent Bridge
Street) and installing a new low-rise cooling tower on new vibration rails. Piping connections are to be made at the roof level and replace degraded valves. This is one of two cooling towers for the building.
Work also includes (PMIS 337427C) replacing one 384 gpm 90’ head condenser pump and one 500 gpm 70’ head circulatory pump (that connects the chiller #1 (PMIS
337240C- Not in contract) to the cooling tower #1 in the basement mechanical room.
Work will include adding variable frequency drives to the pumps. Work includes replacing degraded 4 two-way control valves, 16 ball valves, 1 automatic control valve, 4 butterfly valves, approximately 16 lf of pipe and connections necessary to complete the system, 3 sets of vibration springs and mounting to concrete pads; and program the cooling tower and the pumps to the Trane Building Management System. Electrical work shall include any new conduit and wiring. Please refer to the Contract Specifications and
Plans for complete Scope.
Option #1 is to replace one circulatory pump in the adjacent building basement mechanical room. Work will include adding variable frequency drive to the pump. Work includes replacing degraded 2 two-way control valves, 8 ball valves, 1 automatic control valve, 2 butterfly valves, approximately 8 lf of pipe and connections necessary to complete the system, 1 set of vibration springs and mounting to existing concrete pad;
and program the cooling tower and the pump to the Trane Building Management System.
Electrical work shall include any new conduit and wiring. Please refer to the Contract
