Description

Specifications include, but are not limited to: The University of Texas Health Science Center at Houston (“UTHealth”) is soliciting proposals in response to this Request for Proposal for Selection of a Vendor to provide services related to the decommission of an existing cyclotron, RFP No. 744-R1815 (this “RFP”), from qualified vendors to provide construction services (the “Services”). This is a turn-key project to remove, remediate, and appropriately dispose of materials to meet requirements for license termination as outline in 25 Texas Administrative Code §289.202(ddd)(1)(D)(2). The cyclotron vault has a footprint of approximately 1,080 Square Feet. The floor, walls and ceiling are constructed of rebar reinforced concrete. The north and east walls are 6-feet thick and the south and west walls are 8-feet thick. Access to the vault is through a movable door at the southeast corner. As discussed in Comparison of Recent Characterization Results with Guidelines, approximately four square meters of surface area surrounding location F51 may require remediation to meet the release criterion. Based on the results from the 15-30 cm sample and the 30-40 cm sample at location F51, the depth of remediation for this location is estimated at 50 cm. The area surrounding location F51 appears to be the only area that would require remediation to meet the release criterion, but this assumption should be verified following removal of the cyclotron and other activated components. There may be a need for some additional spot remediation in other areas that could not be properly characterized because of interference with scans and static readings from the cyclotron and other components still in the room. The bid tab is requiring a cost per square foot for concrete removal for this purpose (unit cost). The Winning Contractor will comply with the Multi- Agency Radiation Survey and Site Investigation Manual (MARSSIM) requirements. This area surrounding location F51 would result in approximately 70 Cubic Feet (in place volume) or 10,500 lbs. of activated concrete waste. The bid should include proper disposal of this waste. Waste Manifests to be provided to UTHealth. In addition, the cyclotron and other components will also need to be disposed of as radioactive waste. The MC-40 cyclotron is estimated to weigh approximately 130,000 lbs. (~255 Cubic Feet). The cyclotron beam lines, target array, and various other components are estimated at approximately 1,080 Cubic Feet. These are estimates only and should be verified/determined prior to shipment and disposal. The bid should include proper disposal of this waste. Waste Manifests to be provided to UTHealth.
