Dam Preservation Design Services

Delaware Department of Transportation (DelDOT) is soliciting proposals under RFP 2221F for dam preservation design services, with proposals due December 17, 2026, at 2:00 p.m. local time. The Disadvantaged Business Enterprise (DBE) participation goal is temporarily suspended under a U.S. Department of Transportation Interim Final Rule published September 30, 2025, so no DBE goal applies. The prime consultant must be registered with DelDOT, or have submitted an application for registration, before proposal submission.

The scope covers designing dam improvement and maintenance projects from scoping through Plans, Specifications, and Estimates (PS&E) level, plus construction support during implementation. Additional tasks may include field surveys, right-of-way verification, hydrologic and hydraulic analyses, dam breach modeling, incremental flooding assessments, design of water control structures such as tide gates and dikes, and operation and maintenance manual preparation. Required insurance includes Workers' Compensation, Commercial General Liability ($1,000,000 per occurrence / $3,000,000 aggregate), Errors and Omissions ($1,000,000 per occurrence / $3,000,000 aggregate), and Automotive Liability ($1,000,000 combined single limit). The agreement is subject to Federal Transit Administration requirements, including civil rights, environmental, and federal contracting regulations.

DelDOT anticipates awarding one indefinite-delivery/indefinite-quantity agreement with a four-year term and one possible one-year extension. The anticipated maximum contract value is $20 million per agreement, with no guaranteed minimum. Compensation is cost plus fixed fee, with payroll burden and overhead computed on direct salary costs only at the consultant's audited rate under Federal Acquisition Regulation Part 31. Funding comes from State and Federal sources.

Selection is single-phase, with potential discussions held with up to three most highly qualified firms, followed by ranking and negotiation in order of preference. Questions must be submitted ten business days before the proposal due date. Proposals must be submitted electronically through the Bonfire Procurement Portal.
