Description

The City and County of Denver is seeking letters of interest from qualified firms to provide progressive design‑build services for a new Renewable Natural Gas (RNG) facility at the Denver Arapahoe Disposal Site. The project includes full design, construction, and commissioning of a plant that will process landfill gas and inject high‑BTU gas into a high‑pressure pipeline. Firms must submit a concise letter of interest by the deadline, outlining their capabilities, relevant RNG experience, and ability to meet the 2024 design and construction timeline. • Scope: Design, construction, and commissioning of an RNG plant (approx. $50M+ pre‑qualification threshold). • Submission: Letter of interest (max 4 pages) due May 10 2023, with contact details for follow‑up. • Pre‑qualification: Not required to submit the letter, but will be required later for the RFQ/RFP expected in July.

Budget estimate

$5,000,000 – $15,000,000

No contract value is disclosed, but the solicitation notes a $50 million+ pre‑qualification threshold, indicating a multi‑million‑dollar project. Based on comparable RNG plant design‑build contracts, a reasonable earnings range for the contractor’s scope (design, construction, commissioning) would be roughly 10‑30 % of the total project cost, suggesting a budget between $5 million and $15 million. Factors influencing this range include project complexity, equipment costs, and the use of a Guaranteed Maximum Price (GMP) contract.
