RFQ ATT.2 - LH TM DF Redacted.pdf

This is a Determinations and Findings (D&F) document issued by the 375th Contracting Squadron at Scott Air Force Base justifying the use of Time-and-Materials (T&M) and Labor-Hour (LH) contracts for fire suppression system maintenance services. The document outlines a requirement for semi-annual inspection and maintenance of 28 wet chemical fire extinguishing systems in 13 commercial cooking facilities and annual inspection of 17 wet chemical Guardian III Residential systems in 17 non-commercial facilities at Scott AFB.

The contract will have a base year and four option years, with a possible six-month extension. Market research was conducted on October 15, 2024, under NAICS 922160 (Fire Protection), receiving interest from 3 vendors. The CLIN structure includes both Firm Fixed Price (FFP) and T&M/LH components, with CLINs X003, X005-X007 being T&M/LH due to the unpredictable nature of fusible link replacements, reimbursable parts, additional labor hours, and nitrogen cylinder replacements. The previous contract (FA440721P0009) was awarded to Optimum Low Voltage under a different NAICS code (238220). The document provides detailed justification for why certain components cannot be accurately estimated and therefore require T&M/LH pricing arrangements rather than firm fixed pricing.
