Site work for a civil project in Marietta, Georgia. Completed plans call for site work for a water / sewer project.

The Owner of the project is Cobb County-Marietta Water Authority. The Engineer for the project is Hazen and Sawyer. The Project includes, but is not limited to, the following major elements: 1. Project Overview a. Removal and off-site disposal of +/-30,000 cubic yards of accumulated sediment deposits from interior of ~6-acre reservoir. Repair damaged clay blanket and fabric-formed concrete slope protection inside reservoir. b. Construct permanent reservoir access ramp with concrete pavement and install new fabric-formed concrete slope protection inside reservoir. c. Construct raw water bypass and reservoir drain at Splitter Box. Perform structural, electrical, bridge, and gate repairs, replacements, and/or upgrades to reservoir Inlet, Outlet, and Splitter Box structures, as required. d. All work shall be performed in accordance with the approved Georgia Safe Dams Program plans and specifications and coordinated with CCMWA for plant and reservoir operation. The existing Quarles Plant 2 facility will only be taken out of service during installation of new bypass line. Quarles Plant 2 shall remain in service during construction of the remaining Project. Quarles Plant 1 shall remain in service at all times during construction of the Project. e. Work may require a phased approach based on availability and schedule of products requiring extended lead times. To minimize potential impacts to the water treatment plant operation, Owner may elect to refill and return the reservoir to full operation following completion of Phase I work, requiring Contractor to perform two reservoir draining and dewatering operations. The water treatment plant will only be taken out of service during installation of new bypass line and will be limited to 72 hours to facilitate new bypass connections. The water treatment plant shall remain in service during the construction of the remaining Project. Contractor will provide temporary facilities as necessary to maintain water production. The contract time allowed for Substantial Completion is 450 consecutive calendar days. Due to anticipated extended lead times for manufacture and delivery of materials associated with sluice gates, prefabricated bridges, and pipe fittings and valves, the contract time has been predicated on two separate phases of construction (two potential episodes of reservoir draining/dewatering) and includes up to 365 calendar days for an Administrative Period to run concurrently with Phase I to allow for delivery of materials. At the Owner's privilege, Owner may elect to refill and return the reservoir to full operation during the Administrative Period once Phase I work is complete. Final Completion and readiness for final payment is 480 consecutive calendar days from the date of commencement. THE WORK will be awarded in one Contract.
