Furnish and Deliver Mechanical Joint Fittings and Accessories

The Washington Suburban Sanitary Commission (WSSC) is soliciting bids for the furnishing and delivery of mechanical joint fittings and accessories to support its extensive network of freshwater and sewer pipelines spanning more than 11,000 miles across Montgomery and Prince George’s Counties in Maryland. These fittings, including elbows, sleeves, couplings, and tees in sizes ranging from 3 inches to 20 inches, are critical components used underground to connect pipe sections, valves, hydrants, and other appurtenances, ensuring watertight seals with limited flexibility. The contract operates as a requirements-based, indefinite delivery vehicle with estimated total values between $1 million and $2.4 million over the base term and optional periods, though no unit prices are listed in the solicitation. All deliveries must be made F.O.B. Destination to the Anacostia Warehouse in Hyattsville, Maryland, with a strict 30-day lead time from order placement. Compliance with stringent technical standards is mandatory, including ANSI/AWWA C110, C153/A21.53, ISO 8179 Type 1 for zinc coatings, NSF 61 and 372 for potable water safety, and ASTM standards for bolts and nuts. Fittings must be double cement-mortar lined, arc-sprayed with zinc coating, sealed with an asphaltic coating, and clearly marked with manufacturer details, WSSC stock numbers, country of origin, and compliance designations such as “zinc-1” or “arc.” Packaging must adhere to rigorous specifications: items must be palletized on 42” x 42” four-way entry bases, secured with stretch wrap or banding, separated with cardboard to prevent damage, and labeled with a minimum 1-inch font for WSSC stock numbers and ½-inch font for item descriptions. Inspection occurs at the manufacturing facility, while acceptance takes place upon delivery, and contractors must submit sworn affidavits validating compliance with all performance and testing requirements, including hydrostatic testing at 2.5 times the rated pressure. Bids will be awarded on a Lowest Price Technically Acceptable (LPTA) basis, with technical acceptability serving as a non-negotiable threshold. In addition, the solicitation enforces WSSC-specific socioeconomic requirements, mandating that bidders claiming MBE, WBE, or SLBE status demonstrate commercially useful functions, submit full subcontracting plans, and provide documentation of
