This Project Manual supports a Spot Sewer Rehabilitation Unit Price Contract issued by Washington State for the repair and rehabilitation of existing sewer and drainage infrastructure. The project encompasses spot rehabilitation work on sewer and drainage pipes of varying depths and sizes, including Cured in Place Pipe (CIPP) rehabilitation. Scope of work includes surface removal, excavation, dewatering, bypass pumping, pipe replacement, pipe fittings, maintenance hole and channel work, bedding installation, jet cleaning, CCTV inspection, backfilling, pavement restoration, ADA-compliant curb ramp installation, CIPP installation, and debris removal. Work will be assigned through individual Work Packages, each specifying sewer repair scope between two sequential maintenance holes. The contract has a term of two years, with a minimum award value of $600,000.

The project operates on a unit price contract structure, with payment based on quantities of work completed within each assigned Work Package. Bidders must comply with all specifications outlined in the Project Manual and corresponding Work Package details for each sewer repair assignment. The contract structure allows for flexible work assignment over the two-year period, enabling the jurisdiction to address critical infrastructure rehabilitation needs systematically while maintaining continuity with a single qualified contractor throughout the contract term.
