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. -

The building topped out at 360 m (1,180 ft) in 2008, becoming the third-tallest building in Dubai, after Emirates Park Towers and Burj Khalifa. Almas Tower has 74 floors, 70 of which are commercial alongside four service floors. The tower is located on its own artificial island in the centre of the Jumeirah Lakes Towers Free Zone scheme, the tallest of all the buildings on the development when completed. It was designed by Atkins Middle East, who designed most of the JLT Free Zone complex. The tower is being constructed by the Taisei Corporation of Japan in a joint venture with ACC (Arabian Construction Co.) who were awarded the contract by Nakheel Properties on 16 July 2005.[2] Dubai Multi Commodities Centre (DMCC), the owner of the tower, was the first to move in. -

The QST process enables the cost-effective production of high-strength steels. HISTAR steels are delivered in accordance with the European Technical Approval ETA-10/156. They are in full compliance with European and other national standards. Hot rolled H-beams in HISTAR grades enable the construction of innovative and competitive structures. Engineers take full advantage of the excellent HISTAR properties when designing gravity columns of high-rise buildings, long- span trusses and offshore structures. Furthermore, the new steels are recommended in case of stress governed as well as seismic design. -

The Impact of Increasing Tall Tower Construction in the Middle East MARSH REPORT February 2017
MARSH REPORT February 2017 Sky-high Risk: The Impact of Increasing Tall Tower Construction in the Middle East MARSH REPORT February 2017 CONTENTS 3 Introduction 6 Rising Heights, Rising Risks 8 Heightened Risk Mitigation 12 Mitigating And Transferring Tall Building Risks 13 Conclusion 14 About Marsh 14 About This report 2 Marsh MARSH REPORT February 2017 INTRODUCTION Skylines across the globe have been rising considerably over the past decade. One region where this trend towards taller construction has been particularly visible is in the Middle East. In recent years, the region has become the home to some of the tallest buildings in the world, and recently announced projects show that this trend is not stopping in the near future. With tall building projects skyrocketing, the monumental risks involved in constructing these projects must be considered carefully. Tall building projects are complex and represent a huge concentration of assets, and, if something does go wrong, it could lead to high costs for project developers. Sky-high Risk: The Impact of Increasing Tall Tower Construction in the Middle East 3 MARSH REPORT February 2016 FIGURE 1 The Middle East’s tallest buildings (completed and planned) Source: Skyscraper Center The graphic below (FIGURE 1) shows a selection of the tallest completed, under construction, and proposed buildings in the Middle East. Out of these buildings, 12 are proposed or under construction, demonstrating how skylines in these countries are set to reach new heights over the next decade, maintaining the growing trend towards tall tower construction. The region remained largely unchanged during the 1980s and 1990s, with only the Burj Al Arab (UAE), the Baynunah Hilton Tower (UAE), and the Al Attar Business Tower (UAE) being completed at a height of more than 150 meters. -

GAP YEAR Pine Island Misses a Beat for the First Time in 118 Years
belgrade lakes, maine february 2021 GAP YEAR PINE ISLAND MISSES A BEAT FOR THE FIRST TIME IN 118 YEARS Pine Islanders have long been known for their ability to make do with less. The expression “less is more” has been a hallmark of life at Pine Island since the very beginning, when traveling by train and dirt roads brought camp- ers and staff to a remote island. Since 1902 Great Pond and Pine Island have become less remote, but the camp has consciously maintained a facility that feels remote and where making do with less is providing an even more valuable experience as boys and staff are given the opportunity to unplug and lose the myriad distractions of the modern world. Making do with less is one thing, but this past spring the 90 or so boys and nearly 40 staff who were planning to make do with less learned that they would have to make do with… nothing. After weeks of careful research and communication with Maine Summer Camps, the professional association to which Pine Island belongs; the Maine CDC; and infectious disease experts Pine Island awaits the arrival of PIC 2021. and prospective parents, the Pine Island board of directors decided, out of an article on page 16) of would-have-been Sumner, along with Communications wonderful things that being part of the abundance of caution, not to operate for counselors who lived and worked on Director Sarah Hunter and a generous effort provides. And alumni and friends the 2020 season. Director Sumner Ford, Pine Island for six weeks, completing and energetic board of directors and the world over missed the comforting instead of preparing for his first season many projects and providing on-line Shortfall Task Force, was instrumental knowledge that whatever else was go- at the helm, spent countless hours doing “content” for those boys who wanted to in rallying the PIC troops to provide ing on, the Pine Island adventure was research, having long conversations, and maintain contact with PIC during the crucial financial support to make up for underway.
