Description

The City of Cincinnati is seeking a qualified design‑build contractor to remediate two recurring landslide‑prone sections along US 50 Columbia Parkway and US 52 Riverside Drive. The contract covers full‑service engineering, permitting, construction, traffic management, testing, documentation, and close‑out of geotechnical stabilization works, including retaining structures, rock‑fall protection, and site restoration. The prime contractor must be pre‑qualified by ODOT, provide licensed Ohio professional engineers, and perform at least 30 % of the contract value with its own workforce. The anticipated contract term is roughly 12 months, with a submission deadline of 23 Oct 2026. • Scope includes geotechnical investigation, design of permanent landslide mitigation (retaining walls, soil nails, drainage, rock‑fall barriers), permitting, and construction of the stabilization measures. • Must provide traffic‑control plans, coordinate with ODOT, utilities, and local agencies, and maintain compliance with federal, state, and city regulations. • Required deliverables: calculations, plans, specifications, cost estimates, permit documents, record drawings, warranties, and final close‑out package. • Minimum qualifications: ODOT pre‑qualification, Ohio‑licensed engineers, proven experience on comparable slope‑stabilization and design‑build projects, and a 30 % self‑performance threshold. • Evaluation emphasizes experience (10 pts), technical solution (20 pts), schedule (5 pts), and cost/budget (65 pts). • Small Business Enterprise goal of 5 % applies; SBE participation must be documented. • Submissions are electronic only via the City’s Bonfire portal; a non‑mandatory virtual pre‑submission meeting is scheduled for 1 Oct 2026.

Budget estimate

$5,000,000 – $10,000,000

Based on similar municipal landslide mitigation design‑build contracts in the Midwest, the total contract value is typically between $5 million and $10 million. The estimate considers the need for extensive geotechnical investigation, design of retaining structures, road grading, traffic control, permitting, and construction of two separate stabilization sites. Costs are driven by labor (engineers and skilled construction crews), materials (concrete, steel reinforcement, rock‑fill), equipment, and the requirement to self‑perform at least 30 % of the work. Inflation in construction material prices and the inclusion of a small SBE participation goal may push the upper bound toward $10 M.
