Description

The Kansas Department of Transportation (KDOT) seeks a qualified consulting team to provide professional engineering and design services for the replacement of two I‑70 bridges (Lewis and Clark Viaduct – Eastbound) and associated geometric improvements in Wyandotte County, Kansas. The scope includes project management, environmental review, bridge and roadway design, right‑of‑way acquisition, traffic engineering, rail coordination, public outreach, and grant‑application support, all subject to rigorous pre‑qualification in multiple KDOT Blue‑Book categories and a mandatory Kansas‑licensed land surveyor for ROW services. The selected firm will deliver Phase B design documents, complete NEPA documentation, and be prepared to move forward to construction‑bid phases slated for the late 2020s. • Replace two deteriorated I‑70 bridges and improve roadway geometry (shoulders, alignment, safety). • Deliver comprehensive design packages: structural, geotechnical, hydraulic, traffic, environmental, and ROW plans. • Provide project‑management, quality‑control, NEPA compliance, and public‑outreach deliverables. • Meet stringent pre‑qualification categories (bridge analysis, highway design, geotechnical services, land survey, etc.) and supply a Kansas‑licensed land surveyor. • Submit a concise (≤ 6‑page) PDF proposal with required special attachments (Tax Clearance, Sexual Harassment Policy, Certification of No Current Procurement).

RFP-70-105 KA-2130-05 - I-70 Lewis and Clark Viaduct-Eastbound

Budget estimate

$20,000,000 – $50,000,000

The RFP’s total project cost is estimated at $426 million (inflated to 2035 dollars). Consulting firms typically earn between 5% and 10% of total project construction costs for full‑service engineering design and management. Applying that range yields an estimated contractor fee of roughly $20 million to $50 million, depending on the scope depth, firm size, and risk allocation. The budget will be spread over the design period (approximately three years) with milestone payments tied to deliverable approvals.
