This requirement will include the following scope of work:a. Repair Fire Suppression System, Hangars 3 and 4, Building J00003.Background: Building J00003 includes Hangar #3 and Hangar #4. Hangar #3 consists of approximately 16,742 square feet of first floor support spaces, 973 square feet of second floor support spaces, 73,459 square feet of Hangar Area that also includes 4,531 square feet of mechanical spaces above the center support areas yielding a total square footage of 95,705 square feet. Hangar #4 consists of approximately 16,376 square feet of first floor support spaces, 12,030 square feet of second floor support spaces, 75,010 square feet of Hangar Area that also includes 6,128 square feet of mechanical spaces above the center support areas yielding a total square footage of 109,544 square feet.Scope: Project will repair the failing fire suppression system in Hangars 3 and 4 (Building J00003). Work will include demolishing and repair by replacement of the high expansion foam system with an automatic sprinkler system, the wet-pipe automatic sprinkler system throughout the administrative support areas, and the fire alarm system with a fully addressable system that incorporates the fire alarm system control panel, remote power supply, initiation devices, and notification appliances. Work will also include repairing components of the ventilation and electrical systems and remediating asbestos contaminated material based on the assumption that there is underground asbestos-cement piping. Repair of the fire alarm system circuits and cabling shall be in accordance with the Unified Facilities Criteria (UFC). The fire suppression system will comply with UFC 4-211-01 Aircraft Maintenance Hangars, Chapter 5 (Air Force Specific Criteria), and Headquarters Air Force/A4 Memorandum Aircraft Hangar Fire Suppression System Modernization (3 June 2021).b. Repair Fire Pump House and Pumps, Building J00024.Background: The Fire Pump House (Building J00024) is 2,240 square feet and was built in 1968. The building is constructed of concrete and CMU with a 14-foot-high wall measured at the parapet. The building is built on a concrete slab that has multiple housekeeping pads, cut outs and anchors.Scope: The two (2) existing Fairbanks Morse diesel driven fire pumps at the East end of the Fire Pump House and the single Fairbanks Morse diesel driven foam fire pump at the east end of the Fire Pump House and their related equipment and piping, the existing foam storage tank, and concrete pads will be demolished and removed from the site. The remaining three (3) diesel fire pumps at the west end of the pump house will remain and continue to serve Hangar #1 and Hangar #2. The single exterior man door located in the South wall shall be replaced with a double wide exterior man door to allow work at the East end of the Fire pump house to occur. New fire pump work will include the installation of two (2) electrically driven fire pumps. Each of the two (2) electrically driven fire pumps shall be horizontal split case fire pumps that have an output rating of approximately 75 p.s.i. at 750 g.p.m. with a churn pressure of 88 p.s.i., a 150% rated capacity of 65 p.s.i., and a horsepower rating of approximately 65. The sprinkler, alarm and other support systems will also be replaced during the building repair.c. Repair Waterlines between Buildings J00003 and J00024.Scope: All existing 24-in. diameter underground mains serving Hangars 3 and 4 shall be demolished and removed from site. A new 8-in. Class 52 Ductile Iron Piping (DIP) will be installed from the Pump House (Building J00024) to serve Hangar #3 and Hangar #4. Each dedicated lead-in shall be brought into a new open trench with a metal grate wed walking surface allowing the piping to be visually seen and not be placed under the slab of either building. Replacement of the lines will require patching of the existing parking areas.d. Relocate Office Equipment to Support Repair Efforts.Scope: Existing Hangars 3 and 4 (Building J00003) are occupied. Prior to starting repair work, the contractor will need to relocate a significant amount of office furniture, equipment and specialty tools between hangars. Some furniture disassembly/reassembly will be required. The process will be reversed, moving staff equipment back into the hangars at the end of the project.The construction cost of this project is subject to the disclosure of the magnitude of construction projects in accordance with Defense Federal Acquisition Regulation Supplement (DFARS) 236.204 and is estimated to be between $10,000,000.00 and $25,000,000.00.
