The City of Cheyenne, Wyoming is seeking bids for Invitation for Bid (IFB) #S-6-26, which involves hazardous material abatement and demolition at the High Plains Arboretum, specifically targeting the Greenhouse and Lath House structures located at 8408 Hildreth Road.

Contractors must follow EPA Renovation, Repair, and Painting (RRP) program guidelines and utilize safe work practices during deconstruction and abatement. A mandatory pre-bid meeting is scheduled for October 31, 2025, at 10:00 am at the project site, with electronic bid submissions required via the City's eProcurement Portal by November 12, 2025, at 2:00 pm. Bidders must submit a 5% bid guarantee and provide detailed documentation of worker qualifications, environmental remediation strategies, and compliance with state and federal regulations. The project timeline indicates phased abatement work for the Greenhouse from 4/15/2026 to 5/15/2026 and the Lath House from 5/15/2026 to 6/15/2026, with an estimated Notice to Proceed date of December 17, 2025.

Wyoming state preferences will be applied to labor, materials, and resident contractors, potentially providing advantages to local businesses. The contract includes a $25,000 force account allocation and will withhold 5% retainage throughout the contract term. Successful bidders must provide performance and payment bonds, maintain specific insurance coverages including $1,000,000 commercial general liability and business automobile liability, and comply with workers' compensation requirements. The project requires a two-year warranty period where the contractor remains responsible for addressing any defects or issues arising after project completion. Contractors must also adhere to nondiscrimination guidelines, drug-free workplace policies, and safety program standards. While no specific incumbent vendors are mentioned, the project involves careful deconstruction and preparation of historic structures for potential future renovation, with some components potentially being salvaged for reuse by a subsequent general contractor. The comprehensive nature of the project suggests a detailed and technical approach to environmental remediation and historic structure preservation.
