BN Seawall Assessment, Design, Installation, Repair, and Replacement Services

The City of Detroit Office of Contracting and Procurement is soliciting design-build proposals on behalf of its Human, Homeless, and Family Services Division (Bridging Neighborhoods) for seawall assessment, design, installation, repair, and replacement at privately owned residential properties in Jefferson-Chalmers, with a mandatory pre-proposal site walk on November 19, 2026 at 9:30 a.m. EST and proposals due December 10, 2026 at 12:00 p.m. EST. Detroit equalization credits are available for eligible businesses, and respondents must state whether they will sign a Priority Hire Agreement prioritizing Detroit residents.

The scope covers condition assessment, engineering design including site survey and geotechnical investigation, permitting support, and construction along Fox Creek, Phillip Street, and Lakewood Canals, with properties on Ashland, Klenk, Scripps, Harbor Island, Alter, Lakewood, and Manistique streets. The City cites 15 to 20 parcels, possibly more depending on pricing and available funding, and the cost workbook uses nine properties for evaluation only. Respondents need five years of experience on comparable projects and a Michigan-licensed Professional Engineer, either as a single firm or as prime with licensed subconsultants. Every seawall must reach a minimum top-of-wall elevation of 580.0 feet NAVD88. Imported backfill must meet Michigan Part 201 Residential Generic Cleanup Criteria, with sampling costs borne by the contractor. The contractor must warrant workmanship for two years from substantial completion and maintain performance and payment bonds equal to 100 percent of each task order's not-to-exceed amount. Construction is expected to finish in 2027, and proposals must state the maximum number of properties under active construction and the total completable during the 2027 season.

Pricing uses fixed fees per property for Categories A through C and unit prices for Category D construction by steel sheet pile grade, scope of work, and mobilization by site-access tier. Agency permit fees are reimbursed at cost and excluded from scored pricing, and the Canal Property Owner Discount is informational only. The contract term is two years, with work authorized through per-property task orders and one or more awards possible. Evaluation weights are firm qualifications and Detroit River/canal seawall experience at 30 points, key personnel including PE licensure at 15 points, technical approach at 15 points, schedule and capacity at 15 points, and pricing at 25 points.

Submissions require notarized affidavits, a Certificate of Authority, three years of audited financial statements, and a Statement of Political Contributions and Expenditures. Successful respondents must also provide evidence of a City Treasury Clearance application, which requires at least ten days of processing, and active SAM registration, which requires ten to fifteen days. An AI Factsheet is required if the proposed solution uses artificial intelligence. Questions are due December 7, 2026. Proposals must be submitted through the Bonfire/EUNA portal, and faxed or mailed proposals will not be accepted. Proposals remain firm for 120 days. Payment follows NET 30 terms under the Prompt Payment Ordinance, and no contract takes effect until City Council approval and signature by the Chief Procurement Officer.
