EXPRESSION OF INTEREST (EOI) FOR CONSTRUCTION OF SALTSTONE DISPOSAL UNITS (SDU) 10-12 AT THE SAVANNAH RIVER SITE - LOCATED NEAR AIKEN, SOUTH CAROLINA

PURPOSE The purpose of this inquiry is to determine your interest and qualifications as a potential Offeror build three Saltstone Disposal Units (SDUs) identified by SRR as SDU 10, SDU 11 and SDU 12. These units will be built in pre-determined, site prepared locations by SRR. A tailored Construction Specifications Institute (CSI) Specification and related design drawings. Salient features for each tank are as outlined in the SDU 10-12 attributes section below. The mission of the Saltstone Facility at SRS is to process and dispose of low-level radioactive salt solution from the liquid waste processing facilities. The Saltstone Facility immobilizes low level radioactive salt solution waste by mixing it with a dry material mixture of fly ash, slag, and cement to produce a flowable grout mixture. This grout is poured into large concrete disposal units where it cures to become Saltstone, a non-hazardous material, for permanent disposal. This potential construction subcontract will be performed with labor whose wages are subject to the Davis-Bacon Act. Expected construction duration is sixteen (16) months from start to Mechanical Completion on a 5 X 10 work week. Saltstone Disposal Unit 10-12 is expected to have the following attributes: The tanks are designed to the American Concrete Institute (ACI) 350 Standard and built to the American Water Works Association (AWWA) D110 Type 1 Standard. The concrete mix uses a Class 3 Concrete (Type V cement) that has been tested and approved for use of the SDU application The tanks overall dimensions are 375-ft diameter by 43- ft in height Foundation thickness is 24-inches 25 tapered walls 43-ft in height. Wall thickness is 24-inches at the bottom and 12-inches at the top Roof is sloped (1.5%) and thickness is 12-inches. Roof integrates embeds and penetrations for installation of Balance of Plant (BOP) systems Roof is supported by 208 columns Volume for each tank is approximately 32 million gallons Each tank will be lined and leak tested for tightness by SRR The Scope of Work Includes: Reinforced concrete integral base slab/wall footing construction; Flexible base slab to wall joint including water-stop and bearing and filler pads; Erection of cast-in-place tank core walls including water stop installation between wall segments, lateral cables and vertical post tensioning system; Roof support columns with column capitals; Concrete roof slab construction; External horizontal pre-stressing wrapping of core wall including shotcrete layers and cover using automated equipment; and Epoxy injection of any leaks in walls through cracks, voids or joints, requiring return to site as Leak Tightness testing will be performed by others after installation of an interior liner system The Scope Excludes: Leak Tightness Testing, which will be conducted following installation of an interior liner system; Design; Site Preparation, inclusive of installation of mudmats and HDPE/GCL Liner beneath the floor slab; Balance of Plant infrastructure; and Installation of Interior Liner System The work will be performed to the Liquid Waste Contractor's quality program, compliant with ASME NQA-1. Work will be performed in a greenfield environment and not require construction activities inside a Radiological Buffer Area (RBA).
