The City of Muskegon Water Filtration Plant is seeking proposals from qualified mechanical contractors to replace the 18 discharge valve on its High Service Pump #2. If you have any questions regarding this RFP, please contact either of the following: Joe Buthker Water Plant Superintendent (231) 724-4104 joe.buthker@shorelinecity.com Josh Parmer Chief Water Plant Operator (231) 724-4105 joshua.parmer@shorelinecity.com o Removal and disposal of the existing Allis-Chalmers valve (Figure 1). o Installation of a Henry Pratt 18" rubber-seated ball valve (Figure 2) and an 18" chaindriven butterfly isolation valve. Both the butterfly valve and the ball valve have been procured by the City and are on site. o Installation of the Henry Pratt valve control system procured by the City. Installation must include pressure gauge and Y-strainer on the water supply line. The valve control system must be connected to the existing house water supply, and an additional water feed from the spool piece must also be installed. Each water supply source needs its own quarter-turn ball valve for shut off. See Figure 3 for a similar installation. The control system must exhaust into the floor drain. o The two valves have been purchased and are on site. The control system is scheduled to be delivered in March. If the control system is delayed, it would be acceptable to install the valves before the arrival of the control system and return to finish installation once the control system is on site. o Supply and install a flanged steel spool piece to connect the new valves to the existing header. The interior of the steel spool piece must be coated with a coating that complies with NSF/ANSI 61 standards. o Insulation will be installed where the old insulation was removed, covering any exposed pipe from the header to the top of the discharge valve. Insulation will also need to be completed on two other pumps from previous replacement projects. See Figure 4 for insulation details. o Electrical work will not be included as part of this bid and will be completed by a third party. o Vendor shall provide weekly progress reports of project status, including notification of any critical issues affecting progress. o Bid must include start-up with the contractor on site. o To minimize the downtime of the other high service pump on the common header, the 18" chain-driven butterfly isolation valve must be installed a soon as possible after the old valve has been removed
