This standard facility prototype design was developed to assist Air Force programmers in preparing and validating DD Form 1391 requirements and to assist architect-engineer (A-E) design professionals with approved project-specific design requirements. It is a source of basic programming and functional information for Level 1 confinement facilities. This standard is consistent with the Air Force Corporate Facilities Standards (AFCFS), Unified Facilities Criteria (UFC), and existing design guides. This standard, in conjunction with the AFCFS, defines Air Force expectations for project programming and A-E design decisions. The standard facility prototype design program defines consistent facility requirements across the Air Force enterprise to expedite delivery of a facility. This FC was designed in compliance with AFMAN 32-1084. The objective is to deliver right-sized, flexible, cost-optimized, durable, quality-designed facilities on a life cycle basis to support the Air Force mission.
