The work consists of reinforcement of the interior concrete frames at the filter control building; reinforcement of the clerestory at the roof line; reinforcement of filter deck; constructing new concrete shear walls at the sump area at the bottom of the filters; removal and replacement of two drop gates; removal and replacement of handrails; and all appurtenant work as specified and shown on the drawings. The work also includes replacement of the high-performance butterfly surface wash filter valves, and AWWA rubber lined valves (Butterfly Backwash, Inlet, Outlet, and Drain Filter). These valves will be provided as Metropolitan-Furnished Equipment and will require integration with the existing actuators, including actuator refurbishment. The actuator work will also include piping and electrical modifications within the filter gallery to accommodate dimensional differences and revised actuator locations of the new valves.
