    sports “ In terms of creativity … one should take an attitude not that architects and engineers sit on different mounds taking care of their respective problems, but rather that it is one complementary group working together in creating a building.” – Dr. Lev Zetlin sports On the cover: In 1958, Lev Zetlin – founder of the firm that became Thornton Tomasetti – developed a visionary design for “Tomorrow’s Arena” that was discussed in Engineering News Record, Time and This Week magazines and in the New York Herald Tribune. With a capacity of 200,000, the innovative concept features a suspension-tensioned translucent roof and multi-deck parking ramps integrated into the underside of a concrete stadium bowl, close to the stands. It minimizes the use of land and material while enhancing the spectator experience. In 2013, our computational designers used Rhino Grasshopper and Karamba to create an interactive parametric model of the design. Today, Thornton Tomasetti continues to design sports facilities in the creative spirit Contents of Lev Zetlin. We apply groundbreaking technological tools in innovative ways to help clients and project partners make the future of sports design a reality.

  • New York Building Congress Task Force on Innovation and Best Practices Message from the Chairman
    A REPORT BY THE New York Building Congress Task Force on Innovation and Best Practices Message from the Chairman When I was asked to serve as Chairman of the New York Building Congress, I wholeheartedly agreed, on one condition — that the Building Congress address the issue of innovation and best practices in our industry as part of its agenda. With the City in the midst of another building boom, now is the perfect — and most important — time to devote our attention to building smarter, faster, more safely, and more economically. To accomplish these goals, we must be willing to challenge the status quo, embrace best practices, and implement new ideas and technologies. Over the past two years, the Building Congress Task Force on Innovation and Best Practices has been fully engaged in that process of self-evaluation, thoughtfully considering what we can do as an industry to make us better in everything from procurement reform to building technology and processes, site management, and workforce development. We have found that innovation is all around us, but unfortunately, it hasn’t been as widely distributed and replicated as it needs to be. While many other industries see innovation as a fact of doing business, the building industry has been slow to adopt innovative tools and methods on a broad scale. We continue to build fundamentally the same way we did 50 years ago and arguably even earlier. Yet, imagine going out today and buying a car that was built the same way as the 1965 Studebaker or a computer with 141k of RAM (what a 1965 Univac offered).

Introduction The Petronas Towers were designed to be the centrepiece of a larger complex called the Kuala Lumpur City Centre (KLCC), a mixed-use development with a site area of 14.15 acres, which includes the towers, two other office towers, underground parking and service facilities. The project site is well located in the heart of the commercial district of the city, the ‘Golden Triangle’. Each of the twin towers is eighty-eight storeys high and contains 218,000 square metres of floor space. Rising 452 metres, the towers were certified the world’s tallest buildings by the Council of Tall Buildings and Urban Habitat in 1996. The two towers are connected by a sky bridge at the forty-first and forty-second floors – the sky lobby levels – to facilitate inter-tower communication and traffic. A multi-storey shopping and entertainment galleria connects the office towers at their bases, integrating the entire complex. Other public functions within the complex include the Petroleum Discovery Centre, an art gallery, an 865- seat concert hall and a multimedia conference centre. II. Contextual Information A. Historical background In early 1981 the Malaysian Government decided to move the Selangor Turf Club and its horse-racing track from the heart of the city to the periphery and to redevelop the site to meet the demands of urban and economic growth. The site, occupying 100 acres of land in a burgeoning economic catchment area with access to the city‘s main ring road, offered an ideal location for the development of a new city centre that would reinforce Kuala Lumpur‘s emerging status as an international city in the twenty-first century.
