The Willis Tower is the second tallest building in both North America and the Western Hemisphere and #8 in the world. According to the Council on Tall Buildings and Urban Habitat, a building’s height can be measured in several different ways. The Willis Tower qualifies as the tallest building in the nation in: Height to highest occupied floor (1,431 ft.) Height to the top of the roof (1,450 ft.) While the Willis Tower is no longer the tallest building in the world, it does have the one of the world’s longest elevator rides. You are whisked up 1,353 feet to the highest building observation deck in North America.

After decades of the American office building being dominate, in the last twelve years we have observed a gradual but major shift from office use to residential and mixed-use for Tall Buildings, and from North America to Asia. The turn of the millennium has also seen major changes in the use of buildings in cities having the longest experience with Tall Buildings. Chicago is witnessing a series of office buildings being transformed into residential or mixed-use buildings, a phenomenon also occurring on a large scale in New York. In midtown Manhattan of New York City we note the transformation of major hotels into residential projects. The transformation of landmark projects in midtown New York City is making an impact, but it is not at all comparable to the number of new projects being built in Asia. When conceiving new projects, we should perhaps bear in mind that, in due time, these will also experience major shifts in uses and we should plan for this in advance.

  • CHRYSLER BUILDING, 405 Lexington Avenue, Borough of Manhattan
    Landmarks Preservation Commission September 12. 1978~ Designation List 118 LP-0992 CHRYSLER BUILDING, 405 Lexington Avenue, Borough of Manhattan. Built 1928- 1930; architect William Van Alen. Landmark Site: Borough of Manhattan Tax Map Block 1297, Lot 23. On March 14, 1978, the Landmarks Preservation Commission held a_public hearing on the proposed designation as a Landmark of the Chrysler Building and the proposed designation of the related Landmark Site (Item No. 12). The item was again heard on May 9, 1978 (Item No. 3) and July 11, 1978 (Item No. 1). All hearings had been duly advertised in accordance with the provisions of law. Thirteen witnesses spoke in favor of designation. There were two speakers in opposition to designation. The Commission has received many letters and communications supporting designation. DESCRIPTION AND ANALYSIS The Chrysler Building, a stunning statement in the Art Deco style by architect William Van Alen, embodies the romantic essence of the New York City skyscraper. Built in 1928-30 for Walter P. Chrysler of the Chrysler Corporation, it was "dedicated to world commerce and industry."! The tallest building in the world when completed in 1930, it stood proudly on the New York skyline as a personal symbol of Walter Chrysler and the strength of his corporation. History of Construction The Chrysler Building had its beginnings in an office building project for William H. Reynolds, a real-estate developer and promoter and former New York State senator. Reynolds had acquired a long-term lease in 1921 on a parcel of property at Lexington Avenue and 42nd Street owned by the Cooper Union for the Advancement of Science and Art.

  • Streeterville Neighborhood Plan 2014 Update II August 18, 2014
    Streeterville Neighborhood Plan 2014 update II August 18, 2014 Dear Friends, The Streeterville Neighborhood Plan (“SNP”) was originally written in 2005 as a community plan written by a Chicago community group, SOAR, the Streeterville Organization of Active Resi- dents. SOAR was incorporated on May 28, 1975. Throughout our history, the organization has been a strong voice for conserving the historic character of the area and for development that enables divergent interests to live in harmony. SOAR’s mission is “To work on behalf of the residents of Streeterville by preserving, promoting and enhancing the quality of life and community.” SOAR’s vision is to see Streeterville as a unique, vibrant, beautiful neighborhood. In the past decade, since the initial SNP, there has been significant development throughout the neighborhood. Streeterville’s population has grown by 50% along with new hotels, restaurants, entertainment and institutional buildings creating a mix of uses no other neighborhood enjoys. The balance of all these uses is key to keeping the quality of life the highest possible. Each com- ponent is important and none should dominate the others. The impetus to revising the SNP is the City of Chicago’s many new initiatives, ideas and plans that SOAR wanted to incorporate into our planning document. From “The Pedestrian Plan for the City”, to “Chicago Forward”, to “Make Way for People” to “The Redevelopment of Lake Shore Drive” along with others, the City has changed its thinking of the downtown urban envi- ronment. If we support and include many of these plans into our SNP we feel that there is great- er potential for accomplishing them together.

This paper reviews the evolution of tall building’s structural systems and the technological driving force behind tall building developments. For the primary structural systems, a new classification – interior structures and exterior structures – is presented. While most representative structural systems for tall buildings are discussed, the emphasis in this review paper is on current trends such as outrigger systems and diagrid structures. Auxiliary damping systems controlling building motion are also discussed. Further, contemporary “out-of-the-box” architectural design trends, such as aerodynamic and twisted forms, which directly or indirectly affect the structural performance of tall buildings, are reviewed. Finally, the future of structural developments in tall buildings is envisioned briefly.

Ali2 1Urban Planning and Policy Department, University of Illinois, Chicago, IL 60607, USA 2School of Architecture, University of Illinois at Urbana-Champaign, Champaign, IL 61820, USA Abstract There is much architectural and engineering literature which discusses the virtues of exterior bracing and diagrid systems in regards to sustainability - two systems which generally reduce building materials, enhance structural performance, and decrease overall construction cost. By surveying past, present as well as possible future towers, this paper examines another attribute of these structural systems - the blend of structural functionality and aesthetics. Given the external nature of these structural systems, diagrids and exterior bracings can visually communicate the inherent structural logic of a building while also serving as a medium for artistic effect.
