Description

The City of Mandan is seeking qualified consulting‑engineering firms to develop alternatives, design, and oversee construction of upgrades to its existing wastewater treatment facility under a Construction Manager at Risk (CMAR) delivery method. The scope includes treatment‑process analysis, integration with solids‑handling and odor‑control systems, instrumentation & control upgrades, permitting, financing assistance, community outreach, and optional owner‑advisor services. Firms must demonstrate deep WWTF knowledge, CMAR experience, and the ability to secure grant or loan financing. • Conduct alternatives analysis (conventional & advanced) and design the selected WWTF upgrade. • Provide I&C system review and modernization, plus construction‑administration support during CMAR execution. • Manage permitting, regulatory compliance, financing strategy (grant/loan identification), and public engagement. • Submit a 15‑page SOQ (cover letter excluded) with experience, team qualifications, and references; appendices not counted toward page limit.

Budget estimate

$500,000 – $3,000,000

The WWTF upgrade is likely a multi‑million‑dollar capital project (estimated $10‑30 M). Consulting engineering fees for similar municipal wastewater projects typically range from 5‑10 % of construction cost, plus additional fees for financing and community‑outreach work. Assuming a mid‑range project value of $15 M, the consulting contract could be roughly $750 k to $2 M. Including optional owner‑advisor services could push the high end toward $3 M. Therefore, a reasonable earnings estimate for the winning firm is $0.5 M – $3 M.
