PROGRAM BACKGROUND The Sentinel Operation and Maintenance Complex provides necessary command, maintenance, training, and missile handling facilities for the Sentinel (GBSD) Intercontinental Ballistic Missile (ICBM) to replace the current Minuteman III (MMIII) ICBM over the next two decades. The Sentinel (GBSD) Integrated Command Center (ICC) is necessary to provide centralized operations for: day-to-day mission control, status and security monitoring, weapons systems management, cyber defense, and completing the real-time, tailored leadership picture. The Consolidated Maintenance Facility (CMF) centralizes all Sentinel maintenance functions under one roof while the Integrated Training Center (ITC) is required to consolidate all Sentinel wing-level operational, maintenance, security forces, and cyber-defense training into one facility where airmen train together in a collaborative environment on Sentinel (GBSD) unique systems and devices. The Missile Handling Complex (MHC) is designed to accommodate the Sentinel (GBSD) ICBM system which uses different handling methods and security levels than the current MMIII system. These Sentinel (GBSD) facilities are necessary to improve interaction, collaboration, and efficiency in conducting day-to-day operations, maintenance, and training; they replace outdated, inadequately sized MMIII facilities; they improve working conditions and thus airmen retention; and they directly support the Nation's continued commitment to strategic deterrence. All projects listed below are anticipated to be incrementally funded. SUMMARY DESCRIPTION OF PROPOSED PROJECTS: Summary description of the separate firm-fixed price construction projects is provided below as well as in the individual attachments. Consolidated Maintenance Facility (CMF) Construct a Consolidated Maintenance Facility (CMF) of approximately 181,000 SF to support the Missile Maintenance Squadron and Sentinel mission requirements at Malmstrom AFB, MT. The CMF will provide administrative offices, maintenance shops, and drive-thru high bays with overhead cranes and vehicle exhaust systems to accommodate Transporter Erectors (TE), Payload Transporters (PT), and Missile Transporters (MT). Additional features include a vault, secure storage areas, a loading dock, and shipping/receiving areas with forklift maneuvering space. Construction will consist of a deep reinforced concrete foundation (pier and grade beam), structural slab, structural steel framing, insulated metal panel exterior walls, interior masonry or metal stud partitions, and a sloped standing seam metal roof. Building systems will include electrical, mechanical, water, sewer, fire and lightning protection, security, NIPR and SIPR communications, and emergency power via a diesel generator with fuel storage and secondary containment. Site development will include clearing, grading, drainage, utilities, communications connections, access paving, parking, walkways, and landscaping. The project scope also includes select demolition of existing facilities to support site development and utility tie-ins. Period of Performance is anticipated to be approximately 1,523 calendar days, with a construction award targeted fiscal year 2027. Missile Handling Complex (MHC) Construct a Missile Handling Complex (MHC) which includes two facilities consisting of a 2,193SM (23,605SF) 3-bay facility for transfer of Sentinel (GBSD) missiles via an embedded rails and a 2,490SM (26,802SF) 3-bay facility for positioning and storage of mission ready Sentinel (GBSD) unique transport/erectors (T/E) plus shop and administrative areas. Construction will consist of a deep reinforced concrete foundation (pier and grade beam), structural slab, structural steel framing, insulated metal panel exterior walls, interior masonry or metal stud partitions, and a sloped standing seam metal roof. Building systems will include electrical, mechanical, water, sewer, fire and lighting protection systems, security systems, and NIPR and SIPR communications systems. Overall site improvements include clearing, grubbing, grading, minor demolition, drainage, utility, and communications connections, plus access paving, parking, and walkways as applicable.
