About this file
This is a revised bid schedule for the PKAA Walsen Project in Colorado, presenting itemized pricing for mine closure and reclamation work. The project encompasses eight primary line items including mobilization/demobilization, project safety and environmental planning, sediment and erosion control (1,150 linear feet), installation of mine closures across eight identified features, installation of maintenance closures across three features, re-vegetation work (1 acre), and four additional non-guaranteed line items for supplemental sediment and erosion control, rip rap, imported fill, and machine time. Bidders must submit bids exclusively through the Colorado VSS (Vendor Self-Service) portal at http://www.colorado.gov/vss, with mail and fax submissions prohibited. The bid schedule was revised on June 16, 2026, and bidders must acknowledge receipt of any addenda and complete all pages and line items without amendments.
The bid schedule requires pricing for specific mine closure methods across identified features designated as either sink holes or subsidence features, with closure approaches including machine backfill, monolithic plug installation, and grading. All features identified are privately owned. Bidders must provide unit pricing for applicable items and complete bid amounts for closure features, then calculate grand totals across all sections. The document stipulates that the bid must be signed by an authorized representative of the offeror and that all pages must be returned with no line items left incomplete. The additional bid items for sediment and erosion control, rip rap, imported fill, and machine time hours are designated as non-guaranteed, indicating these costs will only be incurred if deemed necessary during project execution.
