93 -- NONMETALIC FABRICATED MATERIALS SOL 52SBNB5C8780 DUE 081695 POC Romena Moy (301) 975-4999/C.O. Pauline Mallgrave (301) 975-6330 The National Institute of Standards and Technology (NIST) intends to enter into a sole source contract with Dynamic Isolation Systems, 3470 Mt. Diablo Boulevard, Lafayette, California under the authority of 41 U.S.C. 253(c)(1) - Only one responsible source, to provide twenty-nine (29) elastomeric base isolation bearings. These bearings will be used in part of an experimental NIST program to evaluate test methods for seismic base isolation systems in the United States. Dynamic Isolation Systems is the only known domestic company which has the demonstrated capability and technical expertise to produce elastomeric bearings meeting the restrictive geometric and material property requirements. The rubber compound used in the bearings shall be a high damping rubber (HDR) formulation meeting specific criteria for damping, compression set, shear modulus, ozone resistance hardness. The equivalent viscous modal damping of the isolation bearings shall be at least 10% of critical damping, but not greater than 25% of critical damping at the maximum shear strain. Specific dimensional tolerances must also be met. The delivery of the required bearings is required one hundred and twenty (120) days after the date of contract award (FOB Destination - Gaithersburg, MD). This notice of intent is not a request for competitive proposals. Written responses shall contain sufficient documentation to establish a bonafide capability to fulfill the requirement. A solicitation is not available. See Note 22. (0174)
