About this opportunity
The Air Force Sustainment Center's Tinker AFB contracting office (FA8137 AFSC PZIOC) seeks proposals for a Multiple Award Construction Contract for general construction services at Tinker Air Force Base, Oklahoma, with proposals due November 16, 2026 at 1:00 PM local time under Amendment 0006. This is a partial small business set-aside: task orders under $10 million are reserved for the small business pool, and orders of $10 million or more compete full and open, with offerors submitting separate proposals to compete in one or both pools. NAICS is 236210, with a $45 million size standard.
The ceiling is $950 million aggregate across all awarded contracts, with a 5-year ordering period (March 26, 2027 through March 25, 2032) and one optional 5-year period through March 25, 2037. Each awardee receives a $500 minimum guarantee after a mandatory post-award conference. Work covers sustainment, maintenance, repair, alteration/renovation, and minor construction of real property facilities, executed under Design-Build, Progressive Design-Build, Accelerated Design-Build, Construction with Limited Design, or Construction Only methods defined per task order. Design-Build projects start from Government documents equivalent to 15% or greater design, and Construction with Limited Design projects start from 35% to 65% design. Design work must be developed by Oklahoma-licensed credentialed professionals, and design documents require signature and seal by an Oklahoma-licensed Registered Architect.
Work samples must be awarded on or after May 1, 2021, at least 80 percent complete, and limited to ten total samples. Key staffing requires a Contract Program Manager with 10 years of combined experience and two years as Project or Program Manager, plus a Quality Control Manager, a Site Safety and Health Officer, and Superintendents with five years of construction and two years of superintendent experience. Performance bonds are due within 10 days of award. Performance must begin within 10 calendar days of notice to proceed and finish within 365 calendar days. CMMC Level 1 certification is required for initial award, per the September 16, 2026 Q&A.
Evaluation uses a Highest Technically Rated Offerors with Minimum Technical Threshold Rating approach, with no cost or price evaluation at the IDIQ level. Scoring covers seven technical categories: four construction experience categories, design experience, certifications (PMP, LEED, safety, quality), and staffing. Minimum thresholds are 8,190 points for the small business pool (Appendix C) and 7,140 points for the full and open pool (Appendix D). Offerors bear the burden of substantiating claimed points.
Amendment 0006 superseded the October 28 due date and extended it to November 16. Offerors must acknowledge Amendments 0001 through 0006.
