20 Times Square, or 701 Seventh Avenue, is located on the northeast corner where 47th Street and Seventh Avenue intersect.  When finished, 20 Times Square will host a variety of functions, including nearly 75,000 square feet of premium retail space, 30,000 square feet of multi-function entertainment spaces (including a premier nightclub and a 7,000 square foot rooftop terrace that overlooks the heart of Times Square), a 150,000 square foot high-end hotel with 452 guest rooms (to be branded as a Marriott Edition, the collaboration between Ian Schrager and Marriott Hotels), and an 18,000 square foot hi-definition LED sign, rising 120 feet above the bustling streets below and wrapping around both the 47th Street and Seventh Avenue facades.

L&L Holding Tops Out Manhattan Office Tower

L&L Holding Co. has added the final beam of steel to 390 Madison Ave., topping out the former 291-foot tall, 24-story office building to its new height of 32 stories and 373 feet.

The re-massed mid-20th century building now has eight additional floors and offers more than 860,000 square feet of space, according to Yardi Matrix. It is being further transformed into a sleek, light-filled tower featuring massive column-free spans, high ceilings, modern infrastructure, a new façade of transparent, floor-to-ceiling glass, and 13 outdoor terraces.

Ascent Fall 2017


In an unconventional interpretation of mixed-use, the New Brunswick Development Corporation (Devco) completed Gateway Transit Village, consisting of a 24-story building with a connection to the New Jersey Transit/Amtrak station. Located in the heart of downtown New Brunswick, N.J., across from the Rutgers University campus, the new $150-million, 632,000- ft2 structure is the tallest building in the city and has become the epicenter for transit in the area. Its disparate demands were met by an equally diverse set of structural systems.

Cold and Hot Weather Concrete

Discussions of cold and hot weather concrete procedures do not occur until the five-day forecast calls for extreme weather. At that point, everything becomes a rush.

Special concrete mixes, as required, need to be submitted for approval at the beginning of a project. Time is required to test and practice with different temperatures and dosages and to adjust the cocktail of admixtures that form the basis of high-performance concrete today.

But It’s Farley From Over

Moynihan Station today, 10:45 a.m. – Dramatic stage lighting in New York colors illuminates bare steel trusses, a backdrop to the podium where the governor will talk up the new train hall, any minute now. Tables in the far back of the room, behind a crowd of hundreds of construction workers and sweaty guys in suits, are loaded with Penn-Farley coasters and free cider donuts. It’s humid, dark, and a little dusty, but despite the large gathering, there was just a little news at the former post office today: The project’s about to start full-on construction.

Steel Shots: Reimagining Retro

At 390 Madison Avenue in New York City, a 1950s era office building is being reconceived from the inside out — in steel — with new column-free spans and a new facade. The building is essentially being torn down to its steel core and built back up, but this time with higher ceilings and functional outdoor space. Owen Steel Company (an AISC member and certified fabricator) is the steel fabricator for the project.

2017 Making New York History Award

On June 21, 2017, The Skyscraper Museum saluted, for the first time in its twenty-year history, the profession of structural engineering by honoring five firms with a long and proud legacy in creating New York City’s skyline. Before a convivial crowd of more that 150, the Museum presented the 2017 Making New York History Award to leaders of the outstanding engineering companies

$1.6 billion Penn Station expansion plan is a done deal

The Cuomo administration announced Friday afternoon it has completed a $1.6 billion deal with a group of private developers to transform the Farley Building into a western annex of Penn Station. It will house train halls for Amtrak and Long Island Railroad along with retail and commercial space.

Will One of New York’s Future Tallest Also Be Its Greenest?

The $3.1-billion One Vanderbilt commercial office tower that will rise to an expected 1,401 ft across the street from Grand Central Terminal will be unmistakable on the map of midtown Manhattan—and likely far beyond. But the project, set for completion by the end of 2020, aims to be as distinctive within its 1.7 million sq ft as it is on the outside.

Times Square Alteration Opened Up a Can of Worms

Compared with some of its Manhattan neighbors, a high-rise on the corner of Seventh Avenue and West 47th Street looks standard. Like many buildings in Times Square, the 41-story retail-entertainment-hotel development, nearly topped out, has a tower springing from a boxy base that will sport a flashy billboard…
