  • The Design of Akhmat Tower
    E3S Web of Conferences 33, 01022 (2018) https://doi.org/10.1051/e3sconf/20183301022 HRC 2017 The Design of Akhmat Tower Sara Beardsley1, Alejandro Stochetti1, and Marc Cerone1 1Adrian Smith + Gordon Gill Architecture, 111 West Monroe, Suite 2300, Chicago, Illinois 60603, USA Abstract. Akhmat Tower is a 435m supertall building designed by Adrian Smith + Gordon Gill Architecture. It is currently under construction in the city of Grozny, in the Chechen Republic, in the North Caucasus region of Russia. The design of the tower was done during a collaborative process by a multi-disciplinary architectural and engineering team, based primarily in the United States and Russia. During this process, the designers considered many factors including, most primarily, the cultural and historical context, the structural requirements given the high seismicity of the region, and the client’s programmatic needs. The resulting crystalline-shaped tower is both an aesthetic statement and a performative architectural solution which will be a new landmark for Chechnya. “The Design of Akhmat Tower” describes in detail the design process including structural considerations, exterior wall design, building program, interior design, the tuned mass damper, and the use of building information modeling. 1 Introduction In 2014, Adrian Smith + Gordon Gill Architecture (AS+GG) was commissioned to design a signature tower adjacent to the Suzha river in Grozny, Chechnya - a Republic of Russia located in the north Caucasus region near the Caspian Sea. This tower is to be a new icon specifically for the region – and is named after the first President of Chechen Republic, Akh- mat Haji Kadyrov [1]. The design was done by a team of over one hundred people, based primarily in the United States and Russia, and utilized expertise from architects and engineers with vast experience in super-tall building design.

  • In Sight but out of Mind: the Construction of Memory at Three Once Stigmatized Sites in Berlin and Poznań
    IN SIGHT BUT OUT OF MIND: THE CONSTRUCTION OF MEMORY AT THREE ONCE STIGMATIZED SITES IN BERLIN AND POZNAŃ By Stephen Paul Naumann A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy German Studies 2012 ABSTRACT IN SIGHT BUT OUT OF MIND: THE CONSTRUCTION OF MEMORY AT THREE ONCE STIGMATIZED SITES IN BERLIN AND POZNAŃ By Stephen Paul Naumann This study explores cultural identity reflected in the urban landscape at three structures formerly identified with National Socialism: Berlin’s Olympiastadion (Olympic Stadium) and Siegessäule (Victory Column), and Poznań’s Zamek cesarski (formerly Kaiserschloss – or Imperial Castle). My analysis is based on local and state archival work, as well as the examination of literary, visual and media sources in both Germany and Poland. I conclude that after the structures were first used to project meaning from Cold War tropes, both tourism and the enhancement of local identity in the face of European and global influences eventually contributed to the shift in meaning at these spaces in both cities. Poznań’s Zamek cesarski, a palace first commissioned by German Kaiser Wilhelm II, became, with its dedication in 1910, a monument to Prussian-German imperialism in this multi- ethnic Polish-German-Jewish city. Rededicated by the new Polish republic after World War I, the structure was later remodeled by the Nazis for Hitler’s use. One of their most prominent additions is still visible today: the Führerbalkon, a balcony extending off the front of the building for Hitler to watch military parades.

    Journal of Built Environment, Technology and Engineering, Vol. 3 (September) 2017 ISSN 0128-1003 ASSET MANAGEMENT REVIEW OF TALL RESIDENTIAL BUILDINGS IN MAJOR CITIES: CHICAGO, HONG KONG AND SINGAPORE Raymond Cheng Email: [email protected] Reader, Industrial Doctorate (IndD) Programme, Asia e University, Kuala Lumpur, MALAYSIA Ivan Ng Email: [email protected] Executive Director, Russia Capital Investment Corporation Limited, HONG KONG ABSTRACT There is only one residential skyscraper within China’s top 100 tallest buildings in the crowded 24-million- population city of Shanghai, China (and eleven residential skyscrapers among the 134 tallest buildings, i.e. those taller than 150 metres), whereas there are comparatively a lot more skyscrapers used for residential purposes in equally densely populated cities like Hong Kong, Singapore, Kuala Lumpur and, of course, Chicago and New York. This paper, hence, looked, from a historical perspective, how the development of tall buildings in Chicago, Hong Kong and Singapore have evolved to become what we see today. How does the tall building development history of a city help forge the people’s view in terms of living in skyscrapers? Would such help provide explanations and hints as to the future development of skyscrapers in the other cities like Shanghai? Keywords: Tall building, skyscraper, high-rise, development history Learning from the American experience The mythical story of the Tower of Babel tells us that how height, in itself, since the beginning of known history, means power to human beings. But before Elisha Otis revolutionized and refined the safety of the elevator by inventing the elevator brakes1 in 1852, both the Greek mathematician Archimedes of Syracuse and King Louis XV of France could only have envisioned their great ideas through primitive, man-powered, inefficient mechanical lifting devices back in their days.

  • A Review of Design Approaches of Tall Buildings
    buildings Review Sustainability and the 21st Century Vertical City: A Review of Design Approaches of Tall Buildings Kheir Al-Kodmany Department of Urban Planning and Policy, College of Urban Planning and Public Affairs, University of Illinois at Chicago, Chicago, IL 60607, USA; [email protected] Received: 19 June 2018; Accepted: 31 July 2018; Published: 3 August 2018 Abstract: As cities cope with rapid population growth—adding 2.5 billion dwellers by 2050—and grapple with destructive sprawl, politicians, planners, and architects have become increasingly interested in the vertical city paradigm. Given the large-scale problems of skyscrapers, any improvements in their planning, design, and construction would be significant. This paper examines a new crop of skyscrapers that employs green design elements, including aerodynamic forms, greeneries, energy-saving systems, innovative renewable energy techniques, water-saving technologies, rainwater catchment systems, and the like. The examined projects illustrate foremost sustainable design features, strategies, and techniques that help to meet the functional requirements while resulting in attractive forms. They include towers that are completed, under-construction, on-hold, proposed and on the drawing boards. In an attempt to capture a wide-range of innovative ideas and concepts, this paper examines 30 major projects representing major world’s regions that have been active in constructing tall buildings including Southeast Asia and the Far East, the Middle East, Europe, and North America. The discussion section also engages the reader with additional buildings that have employed similar sustainable design. The paper concludes by identifying design approaches that could twin sustainability with iconicity, and highlights some of the shortfalls of intended sustainable design.
