The work includes fabricating and installing two new service gates and two new emergency gates to fit current gate slots, repainting the inlet tunnel liner, gate slots, and marine door, replacing bonnet gaskets and O-ring seals on the main hydraulic gate hoist system, redesigning and fabricating low-flow gate hydraulic cylinders with shop testing, and replacing hydraulic oil piping. Work must occur during restricted windows: November 20–December 11, 2026 and November 20–December 11, 2027, with an optional January 24–February 5, 2028 window.

The contractor must be certified under the AISC Quality Certification Program (Major Bridge, Advanced, Intermediate, or Hydraulic with Fracture Critical endorsement), and the paint contractor must hold SSPC QP3 or AISC sophisticated paint endorsement with certified inspectors. Welders and inspectors must be qualified to SSPC standards. Evaluation applies a best-value tradeoff with Past Performance and Technical Approach weighted equally and significantly more important than Price. Offerors must submit three relevant past performance projects involving gate, bulkhead, or steel structure fabrication and installation completed within ten years, with narratives not exceeding two pages each. The technical approach narrative, limited to 20 pages, must include a detailed Project Management Plan and Gantt chart schedule.
