How Severud engineers are going to lift historic Palace Theater as part of $2B retail development

In a first in the United States, a theater will be permanently raised off the ground and tucked into the new $2.5 billion TSX Tower in Times Square.

“We are certainly no strangers to complex structural engineering projects, but this is one of the most complex assignments we have ever undertaken in our 90-year history,” said Cawsie Jijina, principal at Severud Associates, the consulting engineering firm entrusted with the complex assignment by developers L&L Holding Company and Maefield Development.

NYU Langone Health Science Building: Higher Education/Research Best Project 2018

The 365,000-sq-ft, 18-story NYU Langone Health Science Building was in the design phase when Hurricane Sandy deluged the campus, prompting the project owner to mandate that the team implement major overhauls in hardening the building and its infrastructure.

See the transformation of a NYC landmark into the Moynihan Train Hall

The James A. Farley Post Office building is one of Manhattan’s most storied structures: It was completed in 1913 by the office of McKim, Mead & White, intended to complement the firm’s grand Penn Station, which was located across the street. In 1966, after the demolition of the majestic old train hall, the Farley building became one of the first structures to gain protection under the city’s new Landmarks Law.

Rottet Studio and Studios Architecture Renovate the New York Stock Exchange

It was early afternoon, and the trading floor of that neoclassical temple of commerce, the New York Stock Exchange, was speckled with people quietly gazing at jagged lines rising and falling on screens. Not many years ago, the financial district site would have been marked by people shouting, scribbling traders, and ticker tape littered on the floor. Today, however, trading is conducted silently, around the clock, and largely beyond the physical premises of Wall Street. But at 226 years old, the NYSE is an institution of vast cultural importance, as well as a place where people continue to labor at desks, chew on steak, and hold board meetings. The legendary bell that signals the opening of the market at 9:30 AM continues to ring.

Ennead Architects: Bridge for Laboratory Sciences a Poughkeepsie

Ennead Architects’ project at Vassar College revolves around a wooded area along a stream, Fonteyn Kill, where nineteenth-century philanthropist Matthew Vassar founded the science university that bears his name. The stream was and still is famous for purity of its waters and the wealth of microinvertebrate species that inhabit it, and environmental projects have been implemented to protect it. Vassar College still pursues its mission of protecting Fonteyn Kill and its fauna, and has founded a new science laboratory featuring iconic, highly representative architecture, known as the Bridge for Laboratory Sciences building.

Mass Concreting

By J. Benjamin Alper, P.E., S.E., and Cawsie Jijina, P.E., SECB
 
There are many issues that arise when one places mass concrete, specifically as it relates to reinforced concrete elements in buildings.
These elements, which most typically include reinforced mat foundations, pile caps, footings, piers, and transfer elements, differ from other
reinforced structures such as dams and retaining walls due to high stresses, quantities of steel reinforcement, and the use of high strength concrete. Mass concrete element placement in buildings, therefore, presents unique challenges.

Times Square’s New Addition

By  Cawsie Jijina, P.E., SECB and Steve Reichwein, P.E., S.E., SECB

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.

GATEWAY TRANSIT VILLAGE, NEW BRUNSWICK, N.J

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.
