TECHNICAL APPROACH: COLLABORATION WITH ENGINEERS <br />CITY OF SOUTH BEND: PINHOOK WTP IMPROVEMENTS PROJECT GUARANTEED SAVINGS CONTRACT <br />It deserves careful consideration. To eliminate risks related to the integrity of the existing underdrain blocks, we may <br />be able to use excess material recently obtained during other projects. More research is required to confirm this. If <br />we do not have compatible material, we will discuss the merits of procuring spare components from Xylem and <br />negotiate re-stocking fees for un-used material in advance of placing the base order. <br />VALVES <br />This project includes twenty-six valves that need to be replaced: <br />4 Reaction Basin Influent (RWI) <br />8 Filter Influent (RWI) <br />8 Back Wash Waste (BWE) <br />4 Filter Effluent Valves (FWE) <br />1 Filter to Waste (530) <br />1 Main Plant Effluent (400) <br /> <br />Our approach to this effort will be: <br />1) Field-verify specific dimensions of existing valves (remove insulation as <br />Typical valve <br />required) <br />2) Field-verify actuator required for each valve <br />3) Order replacement valves with corresponding TAG ID <br />4) Receive and immediately verify valves are correct <br />5) Verify electrical connections for new valve actuators <br />6) Prepare old valves for removal (pre-loosen bolts/nuts – 1 at a time) <br />7) Verify adjacent flange dimensions for pre-procurement of bolts <br />8) Stage chainfalls and roust-abouts for material handling/hoisting <br />9) Stage valves in/near installation location <br />10) Stage nuts/bolts/gaskets <br />11) Prepare operations plans for each valve replacement (tools, safety, access, QC, productivity goal, schedule) <br />12) Coordinate plant shut-down <br />13) Remove existing insulation as required <br />14) Shut down plant and proceed with removal/replacement of valves <br /> <br /> <br />Page | 31 <br /> <br />
