Contract source

Description

This solicitation seeks a Construction Manager‑at‑Risk (CMAR) to deliver the Central Biosolids Capacity Expansion at the Metropolitan Water Services’ Central Water Reclamation Facility in Nashville. The CMAR will provide pre‑construction services (phasing, estimating, constructability reviews, GMP development) and act as the general contractor for the construction of new thickening, dewatering, drum‑drying infrastructure, digestion and force‑main upgrades, and refurbishment of existing drum‑dryers. The contract is issued under a competitive sealed‑proposal (RFP) process, with mandatory compliance to Tennessee contractor licensing, Metro background‑check requirements, extensive insurance and bonding, and Equal Business Opportunity (EBO) goals (4 % MBE, 3 % WBE, 16 % SBE/SDV). The solicitation includes several amendments that extended qualification history to 10 years, added online Q&A, and updated the cost spreadsheet. Key milestones run from a pre‑offer meeting on 5 May 2026 to an anticipated contract execution by late July 2026. • CMAR delivery method with Guaranteed Maximum Price (GMP) component. • Scope covers civil, mechanical, electrical, and process‑equipment upgrades for a biosolids treatment plant. • Strict EBO, SBE/SDV, licensing, background‑check, and insurance requirements. • Multiple amendment updates (three total) and a 150‑day offer‑validity period.

Contract value

$35,000,000

The solicitation does not disclose a ceiling or award amount. However, the scope involves a major expansion of a municipal biosolids facility, including new civil works, mechanical equipment upgrades, and a full CMAR service contract. Comparable CMAR projects for mid‑size water treatment expansions in the U.S. typically range from $25 million to $45 million, depending on site conditions, equipment size, and phased funding. Given the multiple work packages (thickening, dewatering, drum‑drying, force‑main, and equipment refurbishment) and the requirement for a Guaranteed Maximum Price, a reasonable ball‑park estimate is approximately **$35 million**. This accounts for design‑build integration, contingency, bonding, and insurance costs, while staying within the budgetary expectations of a mid‑sized metro government.
