North System Air Valve Improvements - Phase III

The North Texas Municipal Water District (NTMWD) is soliciting bids for Phase III of the North System Air Valve Improvements project, which involves replacing and upgrading air valve vaults, associated appurtenances, and related infrastructure at 97 locations along transmission pipelines in Texas. The project encompasses work on a variety of pipeline systems including 90-inch RCCP, 12-inch PVC, and 84-inch AWWA C301 lines, requiring full installation, testing, and commissioning of all components. Contractors must ensure all new installations meet applicable standards such as ASTM C478, ASTM C76, ASTM C443, AWWA C301, and AWS D1.1/D1.2M, with materials and workmanship rigorously inspected and approved at the project site. Deliverables include fully operational, watertight systems with manhole covers rated for 300-pound loads, utilizing O-ring gaskets and non-shrink grout, with final acceptance contingent upon successful performance testing and owner approval. The estimated contract value ranges between $18 million and $20 million, with bids due by June 10, 2026, and submissions required electronically through the NTMWD Project Management Information System (PMIS) or via approved digital channels using specified file formats such as PDF, DWG, DOCX, XLSX, and ZIP. The evaluation process will consider proposed personnel qualifications, past project experience, contract administration capability, cost control measures, quality assurance protocols, safety performance, and MWBE participation, though the precise weighting and basis of award—whether LPTA or best-value trade-off—are not explicitly stated. Insurance requirements mandate that contractors and subcontractors carry commercial general liability and workers’ compensation coverage, with NTMWD named as an additional insured. While no federal FAR clauses apply, the contract is governed by project-specific construction terms, including supplementary conditions and AIA-style provisions. Performance occurs entirely at designated field locations across the NTMWD North System, with no formal FOB terms or federal accounting codes referenced. All work must be coordinated with the Owner’s engineer, and documentation must be submitted per strict format and delivery protocols without deviation.
