About this opportunity
The Washington Suburban Sanitary Commission Water, Maryland is soliciting sealed proposals for comprehensive trunk sewer inspection services, with responses due August 20, 2026 at 2:00 p.m. via WSSC's eProcurement Portal. A non-mandatory pre-bid meeting is scheduled for July 30, 2026, and questions are due August 4, 2026.
The scope encompasses engineering, labor, materials, equipment, and services for inspection of trunk sewers 15 inches in diameter and larger and associated manholes located in wooded rights-of-way and stream corridors throughout the bi-county service area. Work includes manhole location, marking, opening, inspection, and closure; exposed-pipe and stream-crossing evaluation; inflow and infiltration source detection; dye testing; GPS documentation of manholes and exposed sewers (including those under 15 inches); and GIS data integration. All work must comply with NASSCO Manhole Assessment and Certification Program (MACP) standards and OSHA requirements. WSSC maintains approximately 625 miles of trunk sewers, and work is generally clustered by basin, though the consultant must complete work at each site regardless of scattered geographic location without additional compensation.
This is a non-exclusive requirements contract with no guaranteed minimum volume. The base term is four years with a single one-year renewal option at WSSC's discretion. Evaluation weighs Key Personnel (25%), Firm Experience (30%), Technical Approach (20%), and Pricing (25%). Offerors must demonstrate at least five years in business and five similar projects, submit resumes for Project Principal, Project Manager, Project Engineer, Licensed Land Surveyor, Senior Field Technicians, and GIS/CADD Technician, and provide detailed technical approaches addressing inspection methodologies, environmental sensitivity, and data management. No mandatory MBE/SLBE subcontracting goal applies; however, offerors must address MBE/SLBE programs if subcontractors are utilized. Required insurance includes Workers' Compensation, Commercial General Liability ($1,000,000 per occurrence), Business Auto Liability ($1,000,000), Umbrella Liability ($1,000,000), and Pollution Liability ($1,000,000). Performance, payment, maintenance, and prevailing wage bonds equal to 100% of contract value are required. Pricing must remain firm throughout the initial contract period.
