Description

Des Moines Water Works seeks labor and equipment to inspect 12 gate valves in its raw-water gallery system. The work includes mobilization and demobilization, required permits, approximately one day of dive-crew work per valve, and a written report and video for each valve documenting whether it is operable. For operable valves, the contractor must address leakage; remove sediment, grit, and marine growth; lubricate moving parts with suitable underwater lubricant; replace worn gaskets and seals; repair minor surface corrosion; and reinforce anchoring-system connections as needed. If a valve is inoperable and repair is infeasible, replacement may be contracted separately.
