FY23 Water and Sewer Infrastructure – Contract 1
This contract will provide for new water and sanitary sewer main construction throughout the Charlotte, NC water service area. The majority of this contract will be used to build projects for the Street Main Extension Program.
Sugar Creek Wastewater Treatment Plant Alkalinity Storage Replacement
This project includes the removal of two high-density polyethene chemical storage tanks and mixers, the construction of a new chemical storage tank containment area, the installation of three new chemical storage tanks (two in the existing containment area and one in the new containment area), installation of a chemical mixer at each tank, installation of a new chemical metering pump in the new containment area, construction of an enclosed pump room within the containment areas, installation of new and replacement of piping, and construction of a canopy over the new containment area.
Fire Station #36 HVAC Renovation
The mechanical demolition work consists of removing the five (5) existing split system gas furnaces and outdoor air-conditioning condensers, and the one (1) inline exhaust fan above the men’s locker room. All existing ceiling diffusers and grilles shall be demolished and replaced inplace in new work. Existing split system controls, bipolar ionization devices, furnace terminations, and ductwork are to be kept and reused in the new work. The new mechanical work consists of installing five (5) new split system heat pumps and gas furnaces in the same place as demolished split systems, and reusing controls, bipolar ionization, existing furnace intakes/vents and reconnecting to existing gas. Outside air dampers will be adjusted to reduce outside air flow. Existing controls will need to be reworked to account for the change from cooling-only coils to heat-pump coils. A new, smaller, inline fan will be installed in place of demolished fan above men’s locker. New diffusers and grilles will be installed in-place of demolished diffusers and grilles
Briar Creek and Paw Creek Sewer Rehabilitation
This project consists of the sanitary sewer rehabilitation of approximately 13,500 linear feet of sewer outfall with cured-in-place lining. This project will extend along the Briar Creek and Paw Creek outfalls. A 112 linear feet 24-inch diversion sewer will also be constructed under Briar Creek along with a 118 linear feet 8-inch linear feet collector sewer.
FY23 Large Diameter/Sewer Service Contract #1 (Re-bid)
This contract will incorporate the installation of water and/or sanitary sewer services at a single address, water and/or sanitary sewer service dismantlement at a single address or a water/sanitary sewer main line extension. There maybe more than one water and/or sanitary sewer service installation , water and/or sanitary sewer service dismantlement at the same address. Additionally, a single commercial site with water and/or sanitary sewer services to be installed or water and/or sanitary sewer services to be dismantled at different addresses is to be considered one project for the entire commercial site.
FY23 Small Diameter Water/Sewer Service Contract #2 (Re-bid)
This contract is for water and sanitary sewer service installations including connection to the existing public main, which extends a small diameter line to the property. Additionally, a water meter box or sanitary sewer cleanout is included.
