SCOPE
BIDS DUE 4/9, OPEN 4/10. Work under this contract includes: removal of the existing Backwash Supply, Backwash Waste, and Settled Water isolation butterfly valves in Filter Nos. 1-12 at the Pecos Surface Water Treatment Plant (Pecos SWTP). These valves will be replaced with new double eccentric butterfly valves, their associated electric actuators, power and control wiring, and supports. For this work each filter (12 filters total) includes 18-inch Backwash Supply valves, 24-inch Backwash Waste valves, and 36-inch Settled Water valves. The work also includes replacement of existing electrical panelboards with the installation of new Owner provided panelboards for Filter Nos. 1-8, and replacement of the existing mounted high pressure sodium pendent lights with Owner provided LED retrofit kits in the area of Filter Nos. 1-8. In addition to the work in the filter area, this project includes the demolition of the existing baffle walls in Finished Water Reservoirs No. 1 and No. 2 and the installation of new baffle walls in each reservoir. The existing baffle walls are constructed of redwood boards and aluminum panels respectively. The new baffle walls will both be constructed of FRP material and include new supports anchored to the existing roof support columns and column foundations. The new baffle walls will match the existing baffle wall locations, height, and length. Extensive coordination with the Owner is required for this project, and the work must be planned and performed to not impact plant operations as per the contract documents. purchasing@chandleraz.gov Sandy Story - 480-782-3586. sandra.story@chandleraz.gov
