Drawings and Measurements: Any available drawings, floor plans, door dimensions, or measurements relevant to the project. The SOW provides the following dimensions for both openings: Door 101: 3-foot by 7-foot by 1¾-inch hollow-metal leaf in a 6-foot-4-inch-wide hollow-metal frame. Door 101A: 3-foot by 7-foot by 1¾-inch hollow-metal leaf in a 6-foot-4-inch-wide hollow-metal frame. The contractor must verify all measurements before construction and coordinate the final layout with refuge staff. Existing Door Conditions: Details regarding the current door types, configurations, hardware, and any anticipated modifications. Doors 101 and 101A are paired hollow-metal door assemblies in hollow-metal frames. The supporting photographs show existing surface-mounted closers and manual hardware. The available files do not identify required door repairs, frame repairs, reinforcement, latch modifications, or replacement of the existing doors. Electrical Requirements: Information on existing power sources, electrical connections, and any electrical work required for the automatic door operators. The contractor is responsible for extending 120VAC, 5-amp power to each automatic door operator. The available files do not identify the source panel, circuit numbers, spare breaker capacity, routing distances, or whether dedicated circuits are required. Offerors should verify those conditions at the site before submitting a quote. Power: Is there an existing 120VAC circuit with spare capacity near each of the four doors (101, 101A, 127, 128), or should offerors price new circuits from the electrical panel? If from the panel, where is the panel located relative to the doors? The available project files do not confirm that a nearby 120VAC circuit has spare capacity for Doors 101 or 101A, nor do they document the location of the electrical panel relative to the doors. The SOW requires extension of 120VAC, 5-amp power but leaves existing conditions to contractor verification. Operator type: Should the operators be low-energy (ANSI/BHMA A156.19) or full-power (ANSI/BHMA A156.10)? The SOW calls for presence sensors on both swing and approach sides, which is typical of full-power units.
