The building occupies Lot 59 of Square 288, a site of 73,929 square feet bounded by 12th Street, 13th Street, G Street and a public alley. The site consists of the air rights above the existing Macy’s Department store and ground rights for 60 feet behind the existing building, interrupted by the existing Macy’s Loading Dock. The public alley behind the building serves the parking garage and two loading docks (east and west) for One Metro Center and one loading dock for Macy’s Department store.
The structural system of One Metro Center is a cast-in-place flat slab concrete frame with mild steel reinforcement on the interior bays and post–tensioned flat slab at the perimeter bays. The majority of the building is built over and supported by the structure of the existing Macy’s Department store below. The existing structure, built in 1985, was designed to carry the load of a future addition above. The northern 60 feet of the building behind the existing department store is a cast-in-place flat slab concrete structure supported on steel piles.
The roof is protected by a hot fluid applied rubberized asphalt system. This system is covered with polystyrene insulation, beneath a filter fabric, and smooth stone ballast. A paved terrace is located on the central southern portion of the main roof. The paving system is a pressed, pre-cast paver pattern mounted on pedestal supports. There are two mechanical penthouses – one over each of the east and west core areas below. The cooling towers and pump room are located in a screened enclosure north of the central atrium.
The exterior windows of the building are primarily custom-designed preglazed unitized ribbon windows with Clear Low-E insulated glass in light silver colored coated aluminum frames.
Access is controlled and monitored by an electronic access control system, installed and monitored off site by Kastle Systems. Additionally, the building has contracted security officers 24 hours a day, 7 days a week and cameras for surveillance around the building at the major service, parking and pedestrian entrances.
The building’s HVAC equipment is provided water by a closed loop condenser water system. The system is composed of two BAC cooling towers for chilled water, three plate heat exchangers and two Trane air handlers located on each floor. Air is distributed on each floor through variable air volume (VAV) units. VAV boxes serving the building perimeter are equipped with electric resistant elements for seasonal heat. Fresh air is provided by two Trane air handlers located in the penthouse mechanical equipment room.
These units have gas fired pre-heat capability and provides outside air to the mechanical equipment room located on each floor. The fresh air units are adequately sized for the building. A Trane Energy Management system is installed for control of all HVAC equipment.

The power throughout the building is distributed from three (3) 4000 amp 277/480V switchboards located in the below grade switchboard room at the northwest corner of the building. A 640 KW emergency generator is located on the roof. The generator is fed from a 1000-gallon tank located below ground under the northeast parking slab and is equipped with a level monitoring system located on the northwest façade of the building.
The existing fire alarm system consists of pull stations on each stair egress at each floor, smoke detectors in corridors and returnair ductwork, standard audible devices, flashing lights and horns. The building’s fire pump is located on the lower level mezzanine of the existing Macy’s Department store. The pump is rated at 750 gpm. The building is fully sprinklered with a wet recessed sprinkler system located throughout the tenant spaces and common areas, and a surface mounted dry sprinkler system at the loading docks and below-grade parking level.
