PROJECT OVERVIEW

Construction of new sewer service for the Edgar Mine site.

The State of Colorado, Colorado School of Mines (CSM) is soliciting bids from qualified contractors for the Edgar Mine Dry Building (Sewer Line) project.

Scope of Services

The Colorado School of Mines, Edgar Experimental and Teaching Mine is an extension of the Golden campus where students actively participate in mining operations, underground laboratory use by multiple disciplines and gain experience in real-world hands-on activities. With the Mine site in use by the University since the 1960’s, the site continues to grow and develop with new infrastructure. A new Office/Restroom and locker building is currently in construction with completion scheduled January 2026. With this new building coming online, the new sewer project is critical to occupancy and use of the entire facility.

This project will involve the installation of a new sewer line, approx. 1,250 LFT of HDPE down an existing road at the Idaho Springs Edgar Mine site for CSM.

Blasting may be required. However, mining staff at CSM may be able to perform blasting as a cost savings during negotiations. See Bid Alternate (SBP-6.131). Please provide alternate pricing for contractor to provide blasting services.

The scope of services will include full Construction Contracting Services for the project specified during the process of construction and warranty period to the State as per the Advertisement for Bid. Specific tasks to be performed by the Contractor include those generally performed by the construction community where the Contractor is the prime vendor to the State.

Per C.R.S. §38-26-106, if a contract amounts to $150,000 or more, the awarded contractor shall provide payment and performance bonds not less than 50% of the value of the contract. The costs associated with this bond are to be included in the contractor’s bid.
