Architectural Information
General: 901 New York Avenue (officially named "Eleven Story Office Building," according to Record Set) was a unique opportunity for the architects as it inhabited an entire traingular city block in Northwestern Washington, D.C. that intersects three of the five major business thoroughfares. Its exterior facade mostly consists of glass curtan walls and cast stone to create a classical style and approach to its design. This Class A office building is directly across the street from the city's Convention Center and just a few blocks away from the MCI Center Arena.
Major National Building Codes: BOCA 1996; Mixed Use (B, M, A3, S-1, S-2) Non Separated
Zoning and Historical: District of Columbia Title 11 - Zoning; 130’-0” maximum; 35% LSDBE participation
Building Envelope: Granite stone and architectural precast concrete make up most of the exterior facade of the building. Metal canopies and punch windows decorate the face to extend the linear look of the building. Decorative eyebrow-shaped metal canopies accent the main entrances to the building.
Structural Information
General: The construction of 901 New York Avenue brought up many unique factors. Divided into three vertical sections, the underground parking garage was made up of pre-cast concrete, the ground-floor lobby spans 3-stories high, and finishes off with 8 stories of 9-foot high floor-to-floor spaced office space. Constructed mainly out of concrete, the building features a unique post-tensioning system in order to reduce the amount of deflection in the slab. This was necessary due to the large 40' spans of the columns. The floor slab was designed as a flat two-way slab with drop panels at each column. No shear walls were designed: all lateral loads were assumed to be resisted by columns and moment-framing.
Building Systems I
Electrical: Powered by 4 4,000A 460/265V 3-phase 4-wire switchboards
Lighting: Complicated lighting systems adorn 901 NYA, since tenant spaces were individually lit by different designers. Custom fixtures for the staircase, hallways, and office rooms create unique lighting features.
Mechanical: Air distributed by Variable Air Distribution System through 23 units.
Building Systems II
Fire Protection: Wet pipe sprinkler system; dry sprinkler system in areas where freezing is a possibility (i.e. loading docks, overhangs, trash rooms, etc.); dry pre-action in elevator machine rooms.
Transportation: 13 passenger elevators, 2 service elevators; custom-built staircases as desired by tenants
Telecommunications: Advanced systems, in order to have a fully supporting technical staff, have been installed into the building according to the tenants' desires.
