510 Madison Avenue Tower in NYC Wins National Architecture and Engineering Award
September 19, 2011 from American Institute of Steel Construction
(Chicago, IL) – 510 Madison Avenue, a 30-story boutique office building in the Plaza district of New York City’s Midtown Manhattan, has earned national recognition in the 2011 Innovative Design in Engineering and Architecture with Structural Steel awards program (IDEAS2). In honor of this achievement, members of the project team will be presented with awards from the American Institute of Steel Construction (AISC) during a ceremony at 510 Madison Avenue at East 53rd Street on Wednesday, September 21 at 3:30 pm. Conducted annually by AISC, the IDEAS2 awards recognize outstanding achievement in engineering and architecture on structural steel projects around the country. The IDEAS2 award is the highest, most prestigious honor bestowed on building projects by the structural steel industry in the U.S.
The awards presentation will take place the week of SteelDay, September 23 – a national day of networking and learning related to the structural steel industry in the U.S. In celebration of SteelDay, AISC is hosting a special event in NYC at McGraw-Hill headquarters in Midtown Manhattan. It includes a networking lunch followed by a panel discussion on award-winning steel-framed buildings in NYC -- all recent recipients of AISC's prestigious IDEAS2 Award. Panelists will share their views on trends and issues shaping New York's building construction scene now and in the future. Afterwards, guests will take a site tour of the nearby International Gem Tower project currently under construction. Guests may register for this event at www.steelday.org/events. Select New York in the drop-down search menu. From there, select the event: "SteelDay Luncheon, Panel Presentation and Site Tour" and register.

(AISC Member), Wilmington, Del.; construction manager Tishman Corporation (AISC Member), New York.
510 Madison Avenue is a 429-ft-tall, 30-story boutique office building at East 53rd Street in the Plaza district of Midtown Manhattan. This modernist tower provides clean façade lines and flexible interior spaces for tenants. The project is pursuing LEED Gold certification. The building includes a fitness club with a 50-ft pool and a private restaurant, both reserved for tenants and their guests, along with a large landscaped terrace overlooking Madison Avenue. The upper office floors have views of Central Park.
The building is not a traditional economical structure where the lightest steel members were selected to reduce steel tonnage. Rather it is a modern structure that provides the most value for the owner by opening up the floor area, raising the ceiling and letting aesthetic requirements control the design. In looking at the structure, the structural steel virtually disappears, taking up less floor space and providing additional headroom.
“Value-driven steel design – what a concept!” commented Tom Klemens commented Tom Klemens, P.E., senior editor, Modern Steel Construction magazine, Chicago, and a judge in the competition.
510 Madison is engineered to allow open column-free floors. Trusses and transfer girders connect the tower – seventh floor and above – to the base, allowing the tower floors to cantilever over the adjacent building to the west. The upper floors have no interior columns, while the lower floors have only three.
The typical floor-to-floor height is 13 ft, 6 in. which allowed for 10-ft clear height to the finished ceiling. Floor slabs are constructed of 2.5-in. normal-weight concrete over 3-in., 18-gage metal deck. Floor framing members are designed to work compositely with the floor slab and typically span approximately 55 ft. These beams are limited to W18 series to allow maximum headroom with future flexibility.
The building core is compactly located on the south side of the tower. The core is surrounded by steel braced frames which were carefully coordinated with the design team to provide adequate door opening clearances and passages for ductwork from the mechanical room. All building columns are engaged in the lateral resisting load system.
The braced frames incorporate outrigger trusses at the 6th and 30th floors providing lateral stiffness in the north-south direction. Braced frames combined with moment frames along the north and south sides provide resistance in the east-west direction. The braces are wide-flange sections ranging from W14x53 to W14x500. The design was also assessed for multi-hazard, progressive collapse resistance.
The perimeter columns are disengaged from the glass; the façade is anchored into the slab edges. Spandrel beams are W30s with round openings through the web for sprinkler line access to the glass façade.
The truss at the 6th floor is supported by 6-ft, 9-in.-deep built-up plate transfer girders in the ceiling of the fifth floor to reduce the number of interior columns in the lower floors.
The site was studied in a wind tunnel. Using that data and the building properties, engineers at the Boundary Layer Wind Tunnel Laboratory at the University of Western Ontario performed desktop studies and determined the controlling design parameter was to limit torsion at the top-most corner office space.
The fitness club in the cellar is accessed by an architecturally exposed steel stair. The skylight over the pool and the glass footbridge leading from the elevators to private dining are also framed using steel.
The IDEAS2 award dates back over 70 years to the earliest years of AISC’s existence. Roger E. Ferch, P.E. president of AISC, said, “The entire 510 Madison Avenue project team has shown how structural steel can be used to create structures that combine beauty and practicality. The result is a modern office tower that serves its tenants extremely well, while providing an example of what can be achieved when designing and constructing projects with steel.”
