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. The third filter evaluates the financial performance expressed in terms of Net Present Value of a skyscraper project over its life cycle as a function of system solutions being considered, and involves treatment of all major cash flow streams (revenues and expenditures), and their timing. Product and process models are developed to provide the cash flow model with the required scope and time information. The most preferred solution is recommended on the basis of filter two and three results. Efficacy of the developed framework and each filter were assessed through their application to many case studies and through interviews with construction professionals. Findings show that the framework addresses the deficiencies identified in the existing literature and can improve the quality of the decision-making process when selecting preferred solutions for building a specific skyscraper in a specific geographic area. ii Lay Summary The research goal is to develop an evaluation framework for assessing skyscraper engineering and construction technologies in order to recommend the most preferred solution(s) for a specific skyscraper in a specific geographic area to the decision maker. This framework involves the use of three filters and reflects the informal thought processes applied in practice by design and construction personnel. This thesis is a manuscript-based document and has five chapters. Chapter 1 includes an extensive thesis overview given adoption of manuscript thesis format and describes the background, problem statement, proposed solution, methodologies, research motivations, summary of literature review, and contributions of the research. Chapters 2 through 4 describe the findings of filters 1 through 3 of the research work, respectively. Chapter 5 concludes the thesis through summarizing the research work and contributions, and suggests future work for tackling challenges/limitations encountered in this research endeavor. iii Preface The research reported in this thesis consists of: identification of research problems and questions, formulation of research methodologies in pursuing answers to the research questions, comprehensive and critical review for related literature, analysis of design guidelines and development methods of an evaluation framework, and implementation of the framework and its three filters. Case studies related to an iconic skyscraper and interviews with construction practitioners are used for validating and verifying the framework and each filter. The lessons learned from these applications as well as the received feedbacks from these interviews are incorporated in the current version of the framework. The topic of dissertation was proposed by the author who had the passion of conducting research on skyscrapers primarily because of the previous experience in the Middle East in the context of high rise buildings; and agreed by PhD program supervisor Dr. Alan Russell. Process modeling that forms part of filter 3 made use of a linear planning software system (Repcon) developed by Dr. Alan Russell. With the guidance from Dr. Alan Russell, the author was solely responsible for all components of this research including collecting data of the case study project, Abraj el-Bait, Makkah, Saudia Arabia. The content of this dissertation is in the form of three manuscripts prepared for publication, namely Chapters 2 to 4. For each of these, the dissertation author was the primary manuscript author, while the co-author provided guidance on the development and application of various aspects of the research as well as manuscript review and editing.

  • 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.

  • NMB Bank Headquarters the Impressive Performance of a Green Building W ILLIAM B ROWNING
    Reprinted with pemission from the Urban Land Institute the Urban Land Institute www.uli.org In project design and construction, “green” means putting environmen- June June 1992 tal concerns first. 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.

Received: 26 July 2012; in revised form: 5 September 2012 / Accepted: 10 September 2012 / Published: 28 September 2012 Abstract: The tall building is the most dominating symbol of the cities and a human-made marvel that defies gravity by reaching to the clouds. It embodies unrelenting human aspirations to build even higher. It conjures a number of valid questions in our minds. The foremost and fundamental question that is often asked: Why tall buildings? This review paper seeks to answer the question by laying out arguments against and for tall buildings. Then, it provides a brief account of the historic and recent developments of tall buildings including their status during the current economic recession. The paper argues that as cities continue to expand horizontally, to safeguard against their reaching an eventual breaking point, the tall building as a building type is a possible solution by way of conquering vertical space through agglomeration and densification. Case studies of some recently built tall buildings are discussed to illustrate the nature of tall building development in their respective cities.

  • Burj Khalifa, the Shard, and Rivals by Eva Bogomil
    Burj Khalifa, The Shard, and Rivals by Eva Bogomil Introduction From the early days, we have invariably been interested in the world we live in, exploring, analysing, and altering it at our will. Humanity has gone a long way from caves to modern skyscrapers, aiming for ever greater heights. The power of human ingenuity has conquered the elements to reach the sky and beyond. Nowadays technologies allow us to build skyscrapers that totally change our idea of a modern world. Throughout the centuries brilliant engineers have been inventing more advanced and complex technologies, expanding our abilities. The Acropolis, St Paul’s Cathedral, the Eiffel Tower and the Sydney Opera House are all marvellous buildings that have remained objects of admiration for historians, architects, and artists, as well as a source of inspiration for many generations. Even to the general public the structures appear breathtaking. The 21st century saw the dawn of super-skyscraper construction. The Shard, Taipei 101, the Princess Tower, the Abraj Al-Bait Towers, and the Shanghai Tower are just some of the outstanding examples the modern world can be proud of. Burj Khalifa, currently the tallest building in the world, crowns this list of our achievements (Figure 1.0) which keep attracting people, making them wonder how such structures could have been built. Figure 1.0: Height comparison of some of the tallest buildings in the world This essay will focus mainly on London’s Shard and Dubai’s Burj Khalifa. Both of these skyscrapers are unique in their own way, yet similar. The Shard — currently the tallest building in the United Kingdom — dominates London skyline.

  • 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.
