About this opportunity

Written by GovTribe AI ·

The Cobb County-Marietta Water Authority is procuring valve and actuator replacement work at the James E. Quarles Water Treatment Plant, with proposals due October 27, 2022. Reynolds Construction of Georgia, LLC was awarded the contract on November 21, 2022 at a verified low bid of $4.088 million.

The scope spans two facility locations: Quarles Plant 2 and the Quarles Raw Water Pump Station on the Chattahoochee River. At Plant 2, the contractor removes thirty-four electric actuators (thirty from filter valves, two from backwash rate-of-flow valves across Filters 1–3 and 7–8) and ships them to the valve manufacturer for installation on new valves, then installs a total of 112 valve-and-actuator assemblies (110 filter assemblies, two backwash assemblies). The contractor also reinstalls the existing electric actuator from Filter 4 onto Filter 8's effluent rate-of-flow valve to maintain plant operations while Filter 7 remains offline. At the Raw Water Pump Station, the contractor installs five actuators on raw water pump control valves across two pump buildings, removes and properly disposes of existing hydraulic oil actuators and accumulators and associated hydraulic systems, and rotates existing Pratt ball valves on Pump No. 4 and Pump No. 5 in Pump Station No. 2. The work also includes removal of all remaining pneumatic actuators, air piping, and appurtenances at Plant 2.

The award document does not identify contract term, renewal options, or funding source. Addendum 2 was issued during the solicitation period, clarifying project scope and operational continuity requirements.
