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.

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…

Canstruction 2016

Architecture, design, and engineering firms from all over the city are once again flexing their creativity in Brookfield Place with the 24th annual Canstruction NY exhibition and competition. There are 25 teams this year, and their whimsical works use some 90,000 cans of food in total. After the exhibition is over, those will be donated to City Harvest, and then distributed to more than 500 food banks in the tri-state area.

7 of the Tallest Skyscrapers in the United States

When American construction reaches for the sky, it does so mainly in either New York City or Chicago. Those two cities dominate the U.S. skyline in terms of tallest buildings, easily capturing our national skyscraper landscape. And it has been so for decades. But while the locations seldom vary, their ages do, ranging from the 1930s to the 1970s to the past couple years. Here’s the list of the tallest skyscrapers in the United States.

Los Angeles Forum Achieves a Turnaround

February 25, 2014

Following years of disuse the venerable Los Angeles Forum has been given a new life with an upgraded roof structure and refinished interior. Its reopening was celebrated with a giant working turntable on its roof.

Built in 1967, the Forum in Los Angeles was famous as much for its innovative structural roof system as for the many unforgettable performers who dazzled the Los Angelinos beneath it. The “Showtime Lakers” of Magic Johnson won five NBA titles there during the 1980s, and legendary acts from Led Zeppelin to the Jackson 5 to Elvis Presley worked its stage.

“There’s no question, the building is iconic,” says Murray Beynon, a partner of BBB Architects in Toronto. “As we talked to people in L.A., it has almost a mythical status. They think it’s a great building from a visual point of view and many have very special memories there.”
