D -- UPDATE OF NIST DATABASE 46: NIST CRITICALLY SELECTED STABILITY CONSTANTS OF METAL COMPLEXES DATABASE SOL 52SBNB9C1054 DUE 062499 POC Anita K. Tolliver, Contract Specialist, (301) 975-6308, Sandra L. Febach, Contracting Officer, (301) 975-6326, Fax (301) 963-7732 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to enter into a sole source contract with the Texas A&M Research Foundation under the statutory authority of 41 USC 253(c)(1) -- Only one responsible source. This acquisition is for the update of the NIST Standard Reference Database 46 -- NIST Critically Selected Stability Constants of Metal Complexes Database, which shall include the search, evaluation, and addition of new stability constant data to the Database. The data includes non-critical and critical compilations of stability constants. The database will be modified and tuned as necessary to optimize data search, presentation, and printing of hard copy including upgrading to Windows as the primary platform. The completed database will include over 80,000 critically evaluated constants together with conditions of equilibrium measurements for each metal ligand complex and protonated species in aqueous solution found in the literature through 2000. In addition to the stability constant data, the database will provide the chemical and structural formulas for each ligand, the measured critical thermodynamic constants, the experimental conditions of temperature and ionic strength, the equilibria involved for the constants together with the literature citations which will be used in the critical compilation, as well as those discarded as not measuring up to the criteria for critical selection. Texas A&M Research Foundation is uniquely qualified to perform these tasks because they originally collected and selected the data for this database and developed the program. The Government anticipates the award of a firm-fixed price contract. The period of performance for this requirement is a base year with one option year. This notice of intent is not a request for competitive proposals. Written responses to this synopsis shall contain sufficient documentation to establish a bonafide capability to fulfill the requirement. A solicitation is not available. See Numbered Notes 22 and 26.
