DD Construct four Type I modular hangars to contain maintenance hangar overhead space, crew (01) space, and administrative (02) space. The facilities will include overhead bridge crane support facilities, power operated doors, power operated draft curtain between OH areas, and wet sprinkler fire protection system. Work also includes concrete parking aprons, utilities connections, fire protection water storage vault, oil and water separator tanks, repair/replace existing deteriorated sanitary sewer lines including manholes and two new lift stations, repair/upgrade of storm drainage system, demolition of Hangars 2-5 (Buildings 112, 127, 218, and 225), demolition and relocation of displaced functions of the 1942 vintage buildings, 115, 128, 132, 213, 219, 222, 226, 229 and 240, and temporary environmental controls. The total area of the hangars and buildings to be demolished is 9,843 M2 (105,949 SF). Built-in equipment will consist of an aqueous film forming foam (AFFF) fire protection system for the OH space. Special costs include the costs associated with relocating functions out of buildings to be demolished. Special construction features include a stone pile foundation, soil mitigation, and engineered fill that will be required for the site. Temporary environmental controls involve a storm water pollution prevention plan and associated measures to comply with California environmental law. Anti-Terrorism/Force Protection has been addressed in accordance with Department of Defense minimum anti-terrorism standards for buildings. The project also includes technical operating manuals and seismic design features. Sustainable principles will be integrated into the design, development, and construction of the project in accordance with Executive Order 13123 and other laws and Executive Orders. This project will construct four Type I modular hangars and additional parking apron spaces. (Current Mission) REQUIREMENT: Adequate operations facilities are required to house and maintain transient squadron aircraft. The mission of NAF El Centro is to provide support to Navy training and Fleet squadrons, plus Marine Corps, Army, Air Force and foreign detachments. Training includes Air Combat, Low Level Navigation, and Field Carrier Landing Practice (FCLP). NAF El Centro has the unique ability to provide a training area with few encroachment issues, at a low cost per flight, due to the proximity of several ranges. The base has an average loading of seven transient squadrons that use hangars for maintenance, administration, training, and other operations. Generally, one hangar is needed per squadron. The mission of NAF El Centro cannot be effectively accomplished without adequate hangars and aprons. The current hangars were designed for propeller aircraft of the 1940's and are not large enough to accommodate today's jet aircraft, which do not fit completely into the hangars. A total of nine aircraft hangars currently exist at NAF El Centro. Seven are available for tenant and transient use, and one is used as a combined fire and rescue station. With the exception of Hangar 6, the hangars are old World War II vintage structures that have long since exceeded their useful life. They have been determined to be seismically unsafe and could sustain serious damage in a strong earthquake. fire protection systems do not meet current life and safety codes. The Crews must perform most required maintenance outside of the hangars on the apron, where temperatures in the summer often exceed 130 degrees F; temperatures on the tarmac as high as 198 degrees F have been recorded. When maintenance is performed in the hangars, hangar doors can rarely be closed due to placement of the aircraft, with tail sections sticking out or inoperability of the doors due to age and seismic activity. These cramped quarters and extreme conditions lower worker efficiency and morale. Presently, the siting of the hangars and support facilities on the flightline hinders efficient operations. For example, squadrons using Hangars 4 and 5 must go to facilities nearly one mile away to find adequate pilot briefing spaces. This project will correct the poor structural condition, outdated design and siting of four existing aircraft hangars. The proposed aprons will augment the existing apron areas. IMPACT IF NOT PROVIDED : The restrictive spaces will impair the overall training capability and effectiveness of NAF El Centro to meet mission requirements. Detachments will be forced to find adequate facilities at other activities that are already overcrowded and have encroachment issues. Maintenance personnel will continue to work in extreme conditions on the apron or in confined spaces that do not meet seismic or fire codes. 1 Dec 76 Submitted to Congress Page No. 43 B. Equipment associated with this project which will be provided from other appropriations: None JOINT USE CERTIFICATION: The Regional Commander certifies that this project has been considered for joint use potential. Unilateral Construction is recommended. This Facility can be used by other components on an as available basis; however, the scope of the project is based on Navy requirements.
