Coal Creek Sewer Rehabilitation - 2025 Collection Systems Improvement Project

City of Lafayette, Colorado is soliciting sealed bids for the Coal Creek Sewer Rehabilitation (2025 Collection System Improvements Project), with a mandatory pre-bid conference on November 5, 2026 at 10:00 a.m. at Lafayette City Hall and sealed proposals due by 5:00 p.m. on November 18, 2026. The contract is subject to Colorado's Keep Jobs in Colorado Act preference requirements. The opportunity is also tagged to Boulder County and Lakewood City.

The work runs along the Coal Creek Trail from Adonis Court through Erin Way, parallel to the trail, and ties in near the end of Hera Court. It includes approximately 1,920 linear feet of 12-inch C900 sanitary sewer; 320 linear feet of 12-inch cured-in-place pipe (CIPP) liner; 180 linear feet of 8-inch CIPP liner; 150 linear feet of 6-inch CIPP liner; installation of 10 sanitary sewer manholes; lining of 4 existing manholes; and bypass pumping. Associated work covers traffic control, asphalt and concrete removal and replacement, trail replacement, tree removal, abandonment of existing sewer and manholes, and tree, shrub, and seed restoration.

Bidders must submit a bid guarantee bond or certified check equal to 5 percent of the bid amount. The awarded contractor must furnish performance and payment bonds, each equal to 100 percent of the contract price, within five business days of award.

The bid schedule includes 34 line items with unit prices and quantities. Item 10, service connection installation, is pre-priced at $20,000. The City has appropriated funds equal to or exceeding the contract price, and the contract is subject to annual appropriation by the City Council. Progress payments are made monthly at 95 percent of work completed, with 5 percent retainage until substantial completion. Lien rights are unavailable because this is a public works project governed by Colorado Revised Statutes 38-26-105 through 107. Liquidated damages for delay will be specified in the executed agreement.

Contract award is anticipated on or about December 1, 2026. The City anticipates issuing the Notice to Proceed within 30 calendar days of the Notice of Award, and the contract term is 120 calendar days from the Notice to Proceed.
