The City of Covington (City) is seeking Proposals from qualified firms interested in providing Construction Manager at Risk (CMAR) services for a project at the Covington Wastewater Reclamation Facility (the Project). The Project is divided into two separate sub-scopes, Scope A and Scope B. The City of Covington (Owner) will select a Proposer to award, or enter into negotiations for award of, the CMAR Contract. Scope A Work includes modifications to the existing headworks, demolition of the existing aeration basin and construction of a new aeration basin, construction of a new final clarifier, construction of a new RAS/WAS pump station for existing clarifier #3 and proposed clarifier #4, rehabilitation of existing clarifiers #1 and #2, rehabilitation of the existing RAS/WAS pump station, installation of a new sludge press with modifications to the existing sludge press building, expansion of the operations building, and replacement of the surface-mounted mixers in digester #2. Scope B Work includes tertiary filtration and conveyance of treated effluent to the future Alcovy River Reuse Facility, consisting of a cast-in-place concrete splitter box (approximately 14 ft. x 16 ft.) with two stainless steel (SS) weirs, two SS slide gates, aluminum handrail, and aluminum grating; a cast-in-place concrete tertiary filtration structure with two (1 duty + 1 standby) cloth media disc filters, each rated for 2.5 MGD, complete with disks, drive motors, valves, control panel, backwash systems, and equipment hoist, housed beneath an open steel frame structure with a standing seam metal roof; and an effluent pump station with two vertical turbine pumps (each 2.5 MGD), column pipe, discharge head, motors, and control panel, enclosed within a pre-engineered metal building (approximately 30 ft. x 60 ft.) with a cast-in-place concrete floor slab over a concrete wet well. The building will include an interior electrical room, monorail and equipment hoist, personnel and roll-up doors, HVAC, lighting, insulation, finish hardware, and all necessary appurtenances for a complete installation. Work also includes installation of a bulk chemical storage tank for liquid sodium hypochlorite, secondary containment walls, a duplex chemical metering pump skid, yard piping, valves, fittings, interior force main piping and valves, magnetic flow meter, pipe supports, and SCADA control panel. Additional site improvements include dewatering, tree removal, access drive modifications, asphalt paving, demolition of an existing metal building, landscaping, final stabilization, and all other work, equipment, and appurtenances necessary to provide a complete and fully operational system.
