  • Evaluating Skyscraper Design and Construction Technologies on an International Basis
    EVALUATING SKYSCRAPER DESIGN AND CONSTRUCTION TECHNOLOGIES ON AN INTERNATIONAL BASIS by Saad Allah Fathy Abo Moslim B.Sc., Mansoura University, Egypt, 1984 M.Eng., The University of British Columbia, Canada, 2000 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Civil Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) November 2017 © Saad Allah Fathy Abo Moslim, 2017 Abstract Design and construction functions of skyscrapers tend to draw from the best practices and technologies available worldwide in order to meet their development, design, construction, and performance challenges. Given the availability of many alternative solutions for different facets of a building’s design and construction systems, the need exists for an evaluation framework that is comprehensive in scope, transparent as to the basis for decisions made, reliable in result, and practical in application. Findings from the literature reviewed combined with a deep understanding of the evaluation process of skyscraper systems were used to identify the components and their properties of such a framework, with emphasis on selection of categories, perspectives, criteria, and sub-criteria, completeness of these categories and perspectives, and clarity in the language, expression and level of detail used. The developed framework divided the evaluation process for candidate solutions into the application of three integrated filters. The first filter screens alternative solutions using two-comprehensive checklists of stakeholder acceptance and local feasibility criteria/sub-criteria on a pass-fail basis to eliminate the solutions that do not fit with local cultural norms, delivery capabilities, etc. The second filter treats criteria related to design, quality, production, logistics, installation, and in-use perspectives for assessing the technical performance of the first filter survivors in order to rank them.

  • No Longer Just a Hole in the Ground the Adaptive Re-Use of Derelict Quarries
    1 NO LONGER JUST A HOLE IN THE GROUND The Adaptive Re-Use of Resource Depleted Quarries Catherine McCandless Urban Nature and City Design Professor Anne Whiston Spirn MIT 4.213J/11.308J Fall 2013 2 Table of Contents ABSTRACT 3 Introduction 4 Quarrying Activity 5 Cases 6 1. Brownstone Park 7 2. Quarry Falls 9 3. Bellwood Quarry 11 4. Butchart Gardens 13 5. Groundscraper Hotel 15 Conclusion from Cases 17 Looking Forward 18 REFERENCES 19 3 Abstract A quarry is an area from which rocks such as marble, limestone, and granite are extracted for industrial use. Once depleted of their desired resources, quarries are frequently abandoned. The resulting gaping holes can fill with water and form dangerous quarry lakes while others are turned into unsightly landfills. When quarries are in close proximity to urban environments, inhabitants are subjected to pollution and noise, and the undeniable eyesore of an abandoned quarry remains long after excavation is completed. Sustainable redevelopment has become a shining solution for these abandoned, resource-depleted quarries. Dozens of cities in America and abroad have undertaken adaptive re-use projects to transform quarries into a variety of public and private spaces. The potential new uses for these expanses of land include sites for research and education, aquaculture, recreational activities, storage, industry and housing. The goal of my research is to encourage the rehabilitation of land disturbed by quarrying by making the areas suitable for new sustainable land uses. I will examine cases that successfully transformed resource-depleted quarries into commercial and residential communities, and will discuss how further to improve future redevelopment of quarries with greater consideration to environmental impact and biodiversity.

Doing so ENVIRONMENT can mean big pay offs, as this Amsterdam office building proves. NMB Bank Headquarters The Impressive Performance of A Green Building W ILLIAM B ROWNING hen Nederlandsche Middenstandsbank (NMB), then the number four bank in the Netherlands, felt the need, in 1978, for a W new image and a new headquarters, its board of directors set out some unusual criteria. The board asked for an organic building that would integrate art, natural materials, sunlight, green plants, energy conservation, low noise levels, and water, reports Tie Liebe, head of Maatschappij voor Bedrijfsobjecten (MBO), NMB’s real estate develop- ment subsidiary. Per vote of the bank’s employees, the new headquarters would be built in a growing area south of Amsterdam. An integrated team instructed to work across disciplines–an architect, a construction engineer, a landscape architect, an energy expert, and artists– worked for three years designing the building. Construction began in 1983 and was completed in 1987. The NMB building is no monolithic tower. To the contrary, its 538,000 square feet (50,000 square meters) of office space housing 2,400 employees is broken up into a series of 10 slanting towers arranged in an irregular S-curve with gardens and courtyards interspersed. Portions of the complex are supported by a 301,280-square-foot structure (28,000 square meters) containing parking and service areas. Restaurants and meeting rooms line the internal “street” that connects the towers on the mezzanine level.

  • Teacher Background
    Teacher Background Inquiry Description In many parts of the world today, notably in Asia, societies are rapidly transforming. A major part of this transformation is urbanization, the flocking of people from the countryside to cities. A sign of this transformation is the construction of tall buildings. Since the Lincoln Cathedral surpassed the Pyramids of Egypt in 1300 CE, all of the tallest buildings in the world were in Europe and North America. Then, in 1998, the Petronas Towers opened in Kuala Lumpur, Malaysia. Today the five tallest buildings are in Asia (One World Trade Center in New York City is #6) These areas are being transformed because of their integration into the world economic system that itself was the result of the Industrial Revolution in the 19th century in Western societies and the subsequent growth and expansion of those western societies. Interestingly, tall buildings, known as skyscrapers, were a sign of urbanization and industrial growth in Europe and North America at that time. This unit explores the connections between industrialization, urbanization, and skyscrapers, and how it was that skyscrapers were able to be built when and how they were. Key areas of attention will be building materials and related technologies that allowed for taller structures. Teachers are encouraged to use the following notes as they prepare for this unit, and additional secondary resources are listed at the end of this document. Historical Background Agriculture and Monumental Architecture In the long arc of human history, there are two interesting phenomena that might seem separate, but in hindsight are closely related. On the one hand, people have continually intensified their food production, leading to the ability to sustain larger populations on the same amount of land with fewer direct food producers.

  • Hibernia Offshore Oil Platform St
    Hibernia Offshore Oil Platform St. John's, Newfoundland, Canada Structural: Bridges & Marine Location: St. John’s, Newfoundland, Canada Contractor: Kiewit with joint venture partner Norwegian Contractors Owner: ExxonMobil Canada (33.125%), Chevron Canada Resources (26.875%), Petro-Canada (20%), Canada Hibernia Holding Corporation (8.5%), Murphy Oil (6.5%) and Norsk Hydro (5%). The Hibernia Oil Field lies approximately 200 miles (315 km) east-southeast of St. John’s, Newfoundland, Canada. When an offshore platform was deemed necessary to tap this rich petroleum resource, engineers and developers faced serious challenges. The project had to meet a tight construction schedule while overcoming the problems of working in extremely cold weather conditions. The structure had to withstand the most severe environmental stresses of freezing and thawing, ice abrasion, wind and wave action, and chemical attack. In addition, the giant structure was required to float, be towed to the site, and after placement withstand the impact of 5.5 million ton iceberg. To satisfy the tough requirements, a reinforced Gravity Base Structure (GBS) was designed. Weighing more than 1.2 million tons, the Hibernia offshore platform is the largest floating structure ever built in North America. The base raft portion of the GBS was built in an earthen “dry dock.” By flooding the dock, the base raft was floated, towed to a deep-water harbor area, anchored, and construction continued. Once completed, this floating giant was towed to the oil field site and set in place on the ocean floor in about 240 ft. (80m) of water. The GBS was designed to be maintenance free for its 30-year life.

    FFY-2021 through FFY-2028 Construction Work Plan Volume XVIII Table of Contents SECTION I FOREWORD - Letter from the Director SECTION II BUDGETARY PROJECTIONS SECTION III BALANCING PROCESS SECTION IV SUMMARY REPORT CONSTRUCTION WORK PLAN SECTION V Sorted by Federal Fiscal Year and by County Presented for Transportation Commission Consideration December 7, 2020 FOREWORD BUDGETARY PROJECTIONS Budgetary Projections CONSTRUCTION WORK PLAN - FFY 2021 through FFY 2028 The budgetary projections utilized for the basis of the fiscally responsible and financially balanced Construction Work Plan were established through a systematic evaluation of the Department’s anticipated State-Aid and Federal-Aid revenues and expenditures. Projections were performed for Federal Fiscal Years 2021 – 2028 with the Federal Fiscal Year defined as beginning October 1st and ending on September 30th. The budgetary projections only address funding that has been historically and/or categorically committed to State, Federal and Interstate highway system improvements and does not address Department initiated set asides or other mandated programs. For the purposes of the initial projections, an estimated baseline State-Aid amount of $282.03 million and an estimated Federal-Aid amount of $401.88 million was utilized as the Fiscal Year 2021 benchmark. The Federal-Aid amount includes a 7.5% projection overstatement to avoid any potential loss of future Federal-Aid funds due to under programming. Of particular note, the annual baseline State-Aid amount available for Construction Work Plan projects is expected to grow to over $384.56 million during the next eight years. As the Federal-Aid benchmark amount will vary based upon the results of the annual Congressional budgeting process, the estimated projections will require further adjustment and we will adapt our Construction Work Plan accordingly.

  • The Ten Best Buildings of 2017 from the Sublime to the Surreal — Jonathan Morrison Picks the Year’S Most Awe-Inspiring Architectural Projects
    Version: 1 Source URL: http://www.thetimes.co.uk/article/2d71b4da-e648-11e7-b046-23180179278b TIMES2 The ten best buildings of 2017 From the sublime to the surreal — Jonathan Morrison picks the year’s most awe-inspiring architectural projects Jonathan Morrison 22 Dec 2017 00:01:00 It has probably been the most tumultuous year for architecture in a decade. In June the Grenfell Tower fire focused attention on the desperate state of housing in the UK and raised fresh questions over exactly what the profession was doing about it — apart from cladding old tower blocks to improve the neighbours’ view. At the other end of the construction dichotomy the number of billion-pound projects continued to mount, with the glass doughnut of Apple’s headquarters in Cupertino, California (£3.7 billion) being joined by the Bloomberg groundscraper in the City (£1 billion) and countless projects to the east and Middle East. To add to the impression that architects seem to be living on a different planet, their picks for the biggest baubles generated plenty of controversy too. The Stirling Prize, for the UK’s best new building, went to Hastings Pier, built in 1872, while the Royal Institute of British Architects (Riba) gong for the best new house went to a one-off château the size of 13 normal three- bedroom homes and the colour of Donald Trump. On the positive side, some astonishing engineering projects were completed to little fanfare — not least the new €1.5 billion sarcophagus installed at Chernobyl, largely based on a British design, which was slid into place over the collapsing reactor No 4 in October.
