The Navajo Nation Department of Water Resources - Technical, Construction, and Operations Branch (NNDWR-TCOB) is seeking qualified firms for design-build of the Hogback Canal Lining Rehabilitation Project in Shiprock, New Mexico. The purpose of the project is to replace/repair existing concrete canal lining. The contract will be awarded to the firm with the best proposal in terms of: 1) Qualifications / Credentials; 2) Products and Services; and 3) Installation plans and schedule (i.e., construction approach narrative). Adherence to the bid instructions is paramount, otherwise, Navajo Nation Business Regulatory Department will disqualify the bid for non-compliance. Hogback Canal has been designated for repair of its canal lining. Most of the canal lining damage has been caused by expansive soils, characteristics of the Mancos shale prevalent in the area: 1. Most of the concrete lining has minor cracking that needs to be sealed. 2. Overall, approximately 3 to 4 miles of canal lining requires partial or full replacement. 3. Most of the problematic areas are in the section of Hogback Canal right before it enters into Shiprock. In this area, the canal is located on the side of badlands that have soils with low plasticity. 4. Excessive seepage in some areas have begun to erode the sides of the canal lining.
