The North Texas Municipal Water District (NTMWD) is establishing a service contract for the material supply and installation of carbon fiber reinforced polymer (CFRP) liners to internally repair large-diameter concrete and metallic water and wastewater pipes throughout North Texas. The scope of work includes mobilization, surface preparation, joint repairs, and the installation of CFRP/GFRP liners for pipe sizes ranging from 36 to 144 inches. Performance is event-driven, requiring the contractor to mobilize for site walks within 48 hours of a request and initiate emergency repairs within 72 hours of a notice to proceed, with work potentially conducted 12 hours per day, seven days a week. Award is based on a best-value trade-off methodology, with scoring weighted equally between prior experience (35 points) and price (35 points), and methodology and approach (30 points). Bidders must demonstrate significant expertise, including a list of 30 completed CFRP projects and a minimum of five years of applicator experience. Key technical requirements include a five-year warranty supported by a maintenance bond, adherence to AWWA C305 and ASTM standards, and strict quality assurance benchmarks, such as minimum bond strengths of 300 psi for concrete and 700 psi for steel. Administrative requirements include electronic submission via the Bonfire portal, compliance with prevailing wage rates, and the prohibition of certain technologies, such as DJI-branded drones. Contractors must provide proof of insurance within 10 business days of award and submit a Certificate of Interested Parties (Form 1295). As-read bid tabulations indicate competitive bidding, with submissions from Insituform Technologies LLC and Structural Preservation Systems LLC totaling approximately 27.2 million and 25.4 million dollars, respectively.
