New York Times Building in New York, New York. © Bernstein Associates Photographers/Ray Jackson.



The New York Times building is a 52-story high-rise office tower of lightness and transparency topped by a mast that disappears into the sky. Contributing to this vision is an elegant structural steel exoskeleton that is integrated into the architectural design and a glass and ceramic curtain wall design that admits abundant natural light to the building on all floors.

The exposed structural steel provided several challenges for the design team, such as complying with the city’s fire and building codes, detailing the steel to achieve the aesthetic elegance, and designing for forces and movements caused by temperature differentials.

Adding to the building’s appealing façade are thin, horizontal ceramic rods placed on a steel framework 18 inches in front of the low-emissivity glass. The first of its kind in the United States, this curtain-wall design acts as “sunscreen” and helps to reduce the heating and cooling usage while the rods reflect the changing colors of the sky.

Project Delivery Methods

Our structural engineers have experience in the full spectrum of delivery methods, from traditional design-bid-build, to fast-track, construction manager-at-risk (CMR), design-build, Integrated Project Delivery (IPD), Lean Project Delivery (LPD) and hybrids of all of these.

Our collaborative approach is well suited to newer delivery methods that are designed to foster greater cooperation, and we strategically apply the benefits and best practices of these methods to enhance traditional design-bid-build projects.

Vibration Analysis

Successfully engineered buildings both resist anticipated loads and maintain comfortable and functional conditions for occupants. Vibrations from walking, dancing, exercising, synchronous cheering, operating mechanical equipment, construction activities and wind gusts can generate motion that disturbs building occupants or disrupts sensitive operations. We use analysis and monitoring to identify vibration sources and determine methods to reduce or eliminate undesirable effects. We have performed vibration analyses in commercial and residential high-rise buildings, laboratories and industrial buildings, stadium grandstands, operable roofs and more.
