The Colorado Division of Reclamation, Mining and Safety issued a Documented Quote (Bid) solicitation for the Oro Shaft Maintenance Project located 1.5 miles east of Breckenridge in Summit County, Colorado. This procurement sought qualified contractors to replace an existing safety closure on the Oro shaft, which had deteriorated due to erosion of pre-cast concrete panels installed in 1994. The scope of work included removal of existing concrete panels, installation of a polyurethane foam closure with a 30-inch diameter HDPE access culvert and grated access door, grading and diversion channel construction to redirect runoff water away from the shaft, access route improvements, and site revegetation using Zone 5 seed mix. Bidders were required to attend a mandatory pre-bid meeting and site showing scheduled for August 9, 2018, at 10:00 a.m. at the French Gulch Water Treatment Plant, with attendance and sign-in required for bid responsiveness. Bids were due by 4:00 p.m. on August 28, 2018, submitted to the Colorado Division of Reclamation, Mining and Safety at 1313 Sherman Street, Suite 215, Denver, Colorado 80203, with a bid opening scheduled for August 29, 2018, at 10:00 a.m. The project construction schedule was tentatively set for September 24 through October 26, 2018, with a 33-calendar-day completion time after Notice to Proceed, including 10 days for mobilization.

Bidders were required to submit a bid bond equal to 5 percent of total bid price for projects over $50,000, with performance and payment bonds at 100 percent of the original contract price required if the bid exceeded $50,000. Retainage was withheld at 10 percent for bids between $50,000 and $149,999.99, or 5 percent for bids of $150,000 or greater. Liquidated damages were assessed at $400 per day for delays beyond the stipulated completion date.

The project was funded through federal grant money provided to the State of Colorado by the U.S. Department of Interior, Office of Surface Mining, Reclamation and Enforcement under Title IV of the Surface Mining Control and Reclamation Act. This solicitation was cancelled on August 10, 2018, due to insufficient attendance at the pre-bid meeting, with only one contractor present.
