East canal efficiency improvements

The Department of the Interior Bureau of Reclamation intends to solicit construction services for East Canal Efficiency Improvements near Olathe, Colorado, with a sources-sought response deadline of August 31, 2026. The Bureau is evaluating whether to set aside the procurement as a total small business set-aside under NAICS 237110 (Water and Sewer Line and Related Structures Construction); responses to the sources-sought notice will inform that decision.

Work spans four locations along the East Canal on the Uncompahgre Project in Delta County, Colorado. The scope includes furnishing and installing approximately 4,200 feet of 36-inch HDPE pipe for the West Loutsenhizer Arroyo Diversion Pipeline, two parallel 54-inch HDPE pipes for a double barrel siphon, polypropylene profile wall pipe (65 feet of 48-inch and 100 feet of 42-inch diameter) for a side channel spillway, inlet and outlet concrete structures, hydraulic structures including a ramp flume and GK check structure, miscellaneous metalwork, valve installation, and site clearing and grubbing.

The estimated project magnitude is $5 million to $10 million. Substantial completion is required by April 1, 2028, with final seeding and demobilization by November 1, 2028. Critical scheduling restrictions require completion of all canal-located components between November 1 and April 1 annually to avoid irrigation season interruptions. The contractor must coordinate with the Uncompahgre Valley Water Users Association and maintain landowner agricultural operations.

Interested firms must submit company information, bonding capability documentation, experience with similar projects, and three to five past performance references to Tyler Spencer, Contracting Officer, at tyler_spencer@ios.doi.gov by August 31, 2026 at 12:00 PM MDT.
