Professional Design Services-CTH E-Oconomowoc River Tributary Structure

Waukesha County, Wisconsin is seeking professional design services for the CTH E-Oconomowoc River Tributary Structure project through Request for Proposal (RFP) No. 2025039. The Department of Public Works is specifically looking for an engineering consulting firm to design and prepare preliminary and final plans, PS&E documents, and related reports for replacing or rehabilitating an existing 60-foot-long concrete box culvert located in the Town of Merton. Proposing firms must be on the current WDOT Roster of Eligible Engineering Consultants and registered to do business in Wisconsin. The project involves evaluating short-term and long-term solutions for a structurally deteriorated culvert, with construction anticipated in 2027. Proposals are due on September 9, 2025, at 2:00 p.m. CST, with potential interviews for selected finalists scheduled for September 17, 2025. The evaluation criteria will consider firm and project team qualifications (15%), workload (5%), project approach (45%), consultant effort (10%), and cost (25%). Key project milestones include 30% plans due in December 2025, 60% plans in March 2026, and 90% final roads and structure plans in May 2026.

Subconsultants are permitted but must be licensed in Wisconsin and have been in business for at least five years. The contract will be funded entirely by Waukesha County, with the project manager being Ethan Moser. While no specific set-aside designations for disadvantaged enterprises were mentioned, the RFP emphasizes that it is not a traditional bid process and the county is not obligated to accept the lowest cost proposal. The proposed contract includes a payment structure with a lump sum for facilities development process work, with additional compensation for soil borings and potential extra services. The total contract cost will be negotiated, with future amendments based on hourly rates for different staff classifications, an overhead rate, and a fixed fee. The consultant will be required to carry various insurance policies, including professional liability, commercial general liability, and workers' compensation, with Waukesha County named as an additional insured. The project timeline spans from October 2025 to March 2027, with the contract expected to be executed by October 1, 2025, and desirable project completion by December 31, 2027.
