II. Scope of Services

The City of Durango’s primary raw water supply is conveyed from the Florida River to the College Mesa Water Treatment Plant through approximately nine (9) miles of twelve-inch (12-inch), fourteen-inch (14-inch), and twenty-inch (20-inch) buried pipeline. The pipeline has exceeded its anticipated service life and is in need of rehabilitation.

The City anticipates rehabilitating the pipeline in multiple annual phases. The specific limits, schedule, and rehabilitation method for each phase will be determined as pipeline segments are inspected and evaluated.

Fused continuous HDPE lining is currently the preferred rehabilitation method where appropriate; however, existing conditions may require other trenchless or conventional methods.

The anticipated work may include:

1. Pipeline cleaning, inspection, and condition assessment.

2. Rehabilitation using HDPE lining, cured-in-place pipe lining, pipe bursting, conventional removal and replacement, or other appropriate methods.

3. Installation or replacement of fittings, valves, air-release valves, service connections, and other pipeline appurtenances.

4. Pipeline testing, commissioning, site restoration, and coordination of access and shutdowns.

Through this prequalification process, the City seeks to identify contractors with demonstrated experience, qualified personnel, specialized equipment, and the overall capability to successfully perform large-diameter municipal water pipeline rehabilitation. The final project limits, technical specifications, phasing, schedule, and contract requirements will be established in the subsequent project solicitation.

III. INSTRUCTIONS TO BIDDERS

For purposes of this solicitation, a Bidder or Respondent is a contractor submitting materials for prequalification.
