About this file
This is an amendment to an Invitation for Bid (IFB) issued by the Colorado Department of Natural Resources (DRMS) for the Mineral Mountain Mine Closure Project. Amendment No. 1, dated January 30, 2026, modifies the original bid document IFB1 PKAA 2026*0104 and clarifies specific project requirements and scope changes. The amendment removes the prequalification requirement previously listed in Item 0, changes the closure method for Feature ID MM14 from Contractor's Choice to Corrugated Steel Pipe with Bat Ladder per specified standards, and removes Feature IDs CM01 and CM02 from the Safeguarding Additional Mine Openings work item. A revised bid sheet and bid schedule are provided as attachments to this amendment, and all bidders must acknowledge receipt and acceptance of the amendment on the bid sheet and by submitting the revised bid schedule. A pre-bid attendance form is also available.
The amendment does not establish independent pricing terms or funding sources; rather, it clarifies and modifies the technical specifications and administrative requirements of the original invitation for bid. All other terms and conditions of the original IFB remain in effect unless specifically changed by this amendment. Bidders are expected to incorporate these clarifications into their proposals and acknowledge compliance with the revised requirements as a condition of bid submission.
