B -- FEASIBILITY STUDY ON LIQUEFACTION EVALUATIONS BY STRAIN-ENERGY APPROACH SOL 52SBNB5C8640 DUE 042695 POC Marilyn Carter (301) 975-6335/Pauline E. Mallgrave (301) 975-6330 The National Institute of Standards and Technology (NIST) intends to negotiate on a sole source basis with Bechtel Corporation, P.O. Box 193965, San Francisco, CA for a feasibility study on seismic liquefaction potential evaluations by strain-energy approaches. The proposed tasks to be performed by the contractor require expert knowledge in the analysis of laboratory cyclic triaxial test data and seismic ground response. Bechtel Corporation has unique knowledge of and access to high quality cyclic triaxial data on Monterey No. 0 sand and soil from the Savannah River site. The proposed work shall be in collaboration with NIST and the Colorado School of Mines. Deliverable shall be a final report which shall summarize the laboratory and field data, evaluate procedures, and conclusions of the feasibility study with recommendations for subsequent phases of work. Delivery required by September 30, 1995--FOB Destination-Gaithersburg, MD--Statutory authority is 41USC 253(c)(1)--Only one Responsible source that can meet the requirements of the Government--See Note 22.
