- R11PS80381-COMBINED SYNOPSIS/SOLICITATION: TRIAXIAL SOIL TEST EQUIPMENT (i) This is a combined synopsis/solicitation for triaxial soil test equipment prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotations are being requested and a written solicitation will not be issued. (ii) The solicitation number is R11PS80381, and the solicitation is issued as a request for quotation (RFQ). (iii) The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular FAC 2005-48. (iv) The set-aside is Total Small Business, the associated NAICS code is 334519, and the small business size standard is 500 employees. (v) The following is a list of contract line item numbers (CLINs) and items, quantities and units of measure. The geotechnical laboratory at the Materials Engineering and Research Laboratory is in need of new triaxial soil testing equipment. The existing equipment, built in-house in the 1960s and 1970s, is aging and becoming unreliable and obsolete. The existing equipment does not take advantage of modern automation capabilities and is cumbersome to use. A new automated system, the Geotac Sigma-1 System, was purchased in 2003 to test its capabilities and evaluate it as a replacement for the obsolete equipment. It has proven accurate and easy to use. Additional systems are needed for the lab to maintain full triaxial soil testing functionality. Triaxial soil testing equipment to be composed of the following components: (CLIN 0001) One (1) each triaxial testing system including automated pore water and chamber pressure pumps with minimum 300 psi capacity, and a 5,000 pound capacity loading frame; (CLIN 0002) One (1) each triaxial testing system including automated pore water and chamber pressure pumps with minimum 300 psi capacity and a 10,000 pound capacity loading frame; (CLIN 0003) Two (2) each 3 inch triaxial cell with acrylic chamber with a minimum 120 psi capacity; (CLIN 0004) Three (3) each high pressure chamber for 3 inch cells with a minimum of 300 psi capacity; and (CLIN 0005) One (1) each 6 inch triaxial cell with chamber with minimum capacity of 500 psi. (vi) The description of requirements for the items to be acquired is in following information.The following are detailed specifications for CLINs 0001-0005.
