Old Skyscraper Renderings and Construction

In this forum I’d like to discuss buildings proposed or are in prep of how they will be constructed by what materials a specific building will be built.

To set an example if you’re confused, I think One Vanderbilt will be built with a reinforced concrete core with steel, just by looking at the buildings structure and a shot in a video.

Willis Tower (formerly Sears Tower) consists of a structural steel frame that was pre-assembled in sections and then bolted in place on the site. The lightweight building skin — a black aluminum and bronze-tinted glare-reducing glass curtain wall — serves as an insulator between the interior and exterior structure to maintain a relatively constant temperature, in turn minimizing the expansion and contraction of the frame.

Structurally, the building pioneered the use of bundled tube construction. The tower is composed of nine bundled structural tubes resting on reinforced concrete caissons that go down to bedrock. The caissons are tied together by a reinforced concrete mat.

The iconic setback design of the structure was conceived as a direct result of the client’s space requirements. The designers were required to develop a building that incorporated not only very large office floors, which were necessary for the company’s operations, but also a variety of smaller floors for tenants requiring less floor area. The basic structure developed for this program of the tower consists of nine 75-foot-by-75-foot column-free square tubes at the base, forming a cellular-tube frame. Floor sizes were reduced by eliminating 75-foot-by-75-foot increments at varying levels.

What is this for a construction sketch?

That is sketches for 2 Liberty Place in Philadelphia right before it was built. Those were drawn just weeks before One Liberty had reached it’s top floor, but it shows that they wanted to increase floorspace specifically by the request of 2 LP’s anchor tenant Cigna


This is the original design, when the whole Liberty Place was first revealed in April 1984. 2 Liberty was going to be smaller and around 700 feet tall. Now 848 feet tall

Your welcome! I always wondered why 2 Liberty looked so off from One Liberty, now I know why

Aon Center in Chicago a Tube in a Tube construction.

Architects of record Perkins & Will used a relatively new structural form for the Tower. Elevators and other services are bundled together in the core, while the perimeter columns define an outher core. The inner and outer tubes are linked by trusses that support the large open floor plates, and the entire arrangement provides the structure that keeps the building standing.

Design for the 900 North Michigan Avenue by Perkins and Will 1987-89

The Building consist of a concrete frame built on top a steel skeleton. Since the buildings material switshes midway up, the first cranes had to be taken down for two weeks while new cranes for concrete were installed.
