This file is a building code analysis and life safety design document for segregation facilities at Naval Weapons Station Yorktown, Virginia, prepared as part of Design-Bid-Build Project P171 Weapons Magazines. The document establishes applicable codes, standards, and design criteria for a single-story Type II-A construction facility with a building height of 24'-8" and total area of 9,244 square feet.

The facility must comply with UFC 1-200-01, UFC 3-600-01, ICC International Building Code 2018, NFPA 13 (sprinkler systems), NFPA 72 (fire alarm), and NFPA 70 (electrical code). Fire resistance ratings require 1-hour protection for structural frames, bearing walls, and floor/roof construction. The building houses high-hazard industrial use (Group H-1) segregation areas along with business use (Group B) office and collaboration spaces, requiring a 2-hour occupancy separation per UFC 3-600-01. The facility is designed for a calculated occupant load of 32 persons with maximum probable occupancy of 14 persons in high-hazard areas and 5 persons in business areas. Life safety egress analysis confirms eight exits with total capacity of 800 persons, exceeding required capacity. Travel distance requirements are satisfied with common path of travel at 59'-6" to 67'-0" (maximum allowable 100 feet) and total travel distances of 54'-0" to 71'-0" (maximum allowable 75 feet). The design incorporates sprinklered systems allowing reduced travel distances per Life Safety Code requirements. The document also references ammunition and explosives safety standards (NAVSEA OP-5 and DES REG 6055.09) and includes detailed specifications for concrete construction, reinforcement, and structural materials.
