Sanitary CIPP Full Length Liners (Contracting)

The Corporation of the District of North Vancouver is soliciting tenders for ITT-060-26, focusing on the trenchless rehabilitation of fourteen sanitary sewers of varying diameters to address structural defects such as fractures, cracks, and spalling. The scope of work includes the installation of CIPP full length liners, T-Liners for mains 200mm or larger, and lateral connection interface grouting for 150mm mains. All work must adhere to MMCD 2009 Platinum Edition and specific ASTM standards, with key deliverables including 30cm CIPP samples for each pipe length, pressure testing of lateral interfaces, and post-installation CCTV inspection reports submitted within seven days of lining. The preferred completion date for substantial performance is December 31, 2026. Tenders must be submitted as a single PDF via the District's electronic bidding system by October 13, 2026. The award will be based on the best overall value rather than the lowest price, with evaluations considering the contractor's commitment to workplace safety. Required submission documents include a detailed description of proposed CIPP and grouting technologies, Material Safety Data Sheets for resins, a valid business license, and a bid security equal to 10% of the tendered price. Upon award, the successful contractor must provide a performance bond and a labour and material payment bond, each for 50% of the contract price, along with WCB compliance clearance. Payments are processed monthly based on work completed, with retentions of 200% of the estimated deficiency value as the project nears completion.
