Project:  Repair Various Dry Well Lift Stations 1380, 709, & 730 

Solicitation Number:  FA4418-23-R-00**

The 628th Contracting Squadron at Joint Base Charleston, SC is seeking capabilities packages from potential sources for planning purposes for the Repair Various Dry Well Lift Stations 1380, 709, & 730  at Joint Base Charleston, SC - Naval Weapons Station, Goose Creek, SC 29445.

This project will consist of the design of the replacement of three (3) dry well lift stations with wet well lift stations. The components will include perimeter fencing, pre-cast concrete wells each with three submersible pumps, flowmeter, control panels and backup generator. The design of the new lift stations shall comply with industry standards (UFC, NFPA, etc.) and with State, County, and City regulations. Permits that may be required will be evaluated as part the design development.

Lift stations (LS) use mechanical equipment (pumps) and pressurized piping (force main) to lift fluid from a low elevation point to a higher elevation and transport flows to the gravity portions of the collection system. Lift stations can be categorized by their configuration as centrifugal pump lift stations (dry well) or submersible pump lift stations (wet well).

Lift Station (LS) 709 - Records from the lift station are not available to establish its exact age, but per JBC it was last renovated circa 1991. LS 709 is a dry well type lift station. The station consists of a reinforced concrete pump chamber with 2 suction pumps (7.3 HP and 460 V). On top of the pump chamber there is an electrical building with a roof structure housing control panels and electrical equipment. Outside the building there is a rectangular open top wet well divided in chambers which includes a grinder mounted at the inlet. A flow meter vault is also part of the lift station layout. The depth of the pump chamber and wet well are approximately 20 ft.

The demolition will include removal of the wet well, brick building and pump room, and small sections of force main and gravity sewer line. The lift station site has drywell pump control panels, diesel generator, generator automatic transfer switch, electrical panel boards, dry-type transformer, pump variable frequency drives, dry-well pumps and lighting fixtures that are operational and will be removed. Associated equipment conduit and conductors will be removed.

Lift Station 730 - Its exact age is unknown, but per JBC it was last renovated circa 1991. LS 730 is a dry well type lift station. The station consists of a reinforced concrete pump chamber with 2 suction pumps (30 HP and 460 V). On top of the pump chamber there is an electrical building with a roof structure housing control panels and electrical equipment. Outside the building there is a rectangular open top wet well divided in chambers which includes a grinder mounted at the inlet. A flow meter vault is also part of the lift station layout. The depth of the pump chamber and wet well are approximately 20 ft.

The demolition will include removal of the wet well, brick building and pump room, and small sections of force main and gravity sewer line. The lift station site has drywell pump control panels, generator automatic transfer switch, electrical panel boards, pump variable frequency drives, dry-well pumps and lighting fixtures that are operational and will be removed. Associated equipment conduit and conductors will be removed. The outdoor diesel generator with subbase tank is not operational and will require replacement.

Lift Station 1389 is Located on the north side of Pulaski Street across from Petrel Street. Its exact age is unknown, but per JBC it was built or last renovated circa 1983. LS 730 is a dry well type lift station. The station consists of a reinforced concrete pump chamber with 2 suction pumps (40 HP and 230 V). On top of the pump chamber there is an electrical building with a roof structure housing control panels and electrical equipment. Outside the building there is a rectangular open top wet well divided in chambers which includes a grinder mounted at the inlet. A flow meter vault is also part of the lift station layout. The depth of the pump chamber and wet well are approximately 20 ft. This lift station is not inside a Flood zone area.

The demolition will include removal of the wet well, brick building and pump room, and small sections of force main and gravity sewer line. The lift station site has drywell pump control panels, diesel generator, generator automatic transfer switch, electrical panel boards, pump variable frequency drives, dry-well pumps and lighting fixtures that are operational and will be removed. Associated equipment conduit and conductors will be removed.

The anticipated performance time is 563 calendar days.
