EXPRESSION OF INTEREST (EOI)- for the Refurbishment of Concrete Coated Waste Transfer Pits

Washington River Protection Solutions LLC (WRPS) located in Richland; Washington at the Hanford Clean-Up Site has a requirement to comply with the requirements of Washington Administrative Code (WAC) 173.303.640. For the waste transfer piping system which transport dangerous waste between underground storage tanks, secondary containment concrete vaults are utilized at various piping termination points.

These concrete vaults which contain additional piping, valves, structural components, etc. are referred to as pits. To satisfy the regulatory requirements, WRPS installs and maintains special protective coatings with inspections performed by National Association of Corrosion Engineers (NACE) Coating Inspector Program (CIP) qualified inspectors in accordance with the WRPS procedures. WRPS currently has multiple waste transfer concrete pits that have not been in service for multiple decades.

To facilitate new projects, these pits will require extensive repair and refurbishment to reestablish secondary containment and pass a NACE inspection to demonstrate that they are fit for use. The refurbishment presents several challenges with existing pit obstructions, radiological contamination, and radiation exposure to workers.

Generally, long reach and/or remote tools are used to facilitate most of the work at these structures to mitigate a number of the hazards the workers would be exposed to if a manned entry was to be performed.

WRPS is issuing this Expression of Interest (EOI) to identify prospective Subcontractors who may have the capability to provide commercial and/or special tools and relevant industry experience to inform the execution of work to repair and refurbish these pits while maximizing worker safety and timely execution.
