3 World Trade Center

The 3 World Trade Center is a Contemporary skyscraper designed between 2006 and 2006 by Rogers Stirk Harbour + Partners, with Richard Rogers as lead architect, in association with Adamson Associates Architects, and built between 2010 and 2018, for a reported $900 million dollars, in New York, NY.

3 World Trade Center is not the only name you might know this building by though. It is common for companies to want to attach their names to iconic buildings when they move in, or for the general public to come up with nicknames, and this one is no exception. The 3 World Trade Center is also known, or has been known as, 3 WTC, or 175 Greenwich Street.

Its precise street address is 175 Greenwich Street, New York, NY. You can also find it on the map here.

In 2019 the 3 World Trade Center was awarded with the The American Architecture Award.

The office building features five floors dedicated to retail stores, two of which are underground, and connections to subways and trains at the World Trade Center Transportation Hub.

The lower basement levels house loading docks for trucks, and parking for port buses, and cars, with the lowest is primarily designated for mechanical and support functions.

Rogers Stirk Harbour + Partners, with Richard Rogers as the lead architect, was the architecture firm in charge of the architectural design, in association with Adamson Associates Architects.

That being said, architecture is a complex discipline involving many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the 3 World Trade Center a reality:

• WSP Cantor Seinuk in charge of Structural Engineering
• Tishman Construction as the Main Contractor
• Permasteelisa Group in charge of Facade Consultancy
• Schindler as the company in charge of the elevators system
• Silverstein Properties as the Main Developer
• Jaros Baum & Bolles in charge of MEP Engineering

The 3 World Trade Center can be categorized as a Contemporary building.

The 3 World Trade Center uses a trussed-frame structure made of steel columns and poured concrete over metal decking slabs.

A trussed-frame structure uses a combination of beams and columns to sustain the building's weight, and diagonal elements to provide stability against horizontal forces such as wind or seismic activity by triangulating the structure. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade uses a non-load bearing curtain wall system. This means the curtain wall modules are anchored to the building's structural frame, typically by being attached to the edge of the floor slabs. The curtain wall system connects to the slabs using brackets, anchors, and mullions, which transfer the loads imposed by wind and temperature changes, to the building's primary structural elements.

This setup allows the curtain wall to accommodate differential movement between the facade and the structural frame, such as thermal expansion, floor deflection, or sway from wind forces. This system's integration with the slab edges also allows for continuous insulation and weatherproofing layers.

On the east and west facades, a diagonally arranged load-bearing steel exterior truss with stainless steel-clad beams for protection against the elements creates K-shaped bracing that eliminates the need for structural columns at the corners

From an aesthetic point of view, the facade features low-E double-glazed glass and stainless steel. The panels are made of annealed glass with a laminated interlayer for increased resistance to breakage and a coating to reflect the surrounding landscape.

Floors 17, 60, and 76 provide tenants with outdoor terraces.
