The world of construction is intrinsically linked with that of finance, from the procurement and tendering stage of projects right through to valuation of buildings. In addition to this, things like administrations, liquidations, mergers, take-overs, buy-outs and floatations affect construction firms as they do all other companies. This book is a rare explanation of common construction management activities from a financial point of view. While the practical side of the industry is illustrated here with case studies, the authors also take the time to build up an understanding of balance sheets and P&L accounts before explaining how common tasks like estimating or valuation work from this perspective. Readers of this book will not only learn how to carry out the tasks of a construction cost manager, quantity surveyor or estimator, they will also understand the financial logic behind them, and the motivations that drive senior management. This is an essential book for students of quantity surveying or construction management, and all ambitious practitioners.

The book provides suggestions on how to start using bionic optimization methods, including pseudo-code examples of each of the important approaches and outlines of how to improve them. The most efficient methods for accelerating the studies are discussed. These include the selection of size and generations of a study's parameters, modification of these driving parameters, switching to gradient methods when approaching local maxima, and the use of parallel working hardware. Bionic Optimization means finding the best solution to a problem using methods found in nature. As Evolutionary Strategies and Particle Swarm Optimization seem to be the most important methods for structural optimization, we primarily focus on them. Other methods such as neural nets or ant colonies are more suited to control or process studies, so their basic ideas are outlined in order to motivate readers to start using them. A set of sample applications shows how Bionic Optimization works in practice. From academic studies on simple frames made of rods to earthquake-resistant buildings, readers follow the lessons learned, difficulties encountered and effective strategies for overcoming them. For the problem of tuned mass dampers, which play an important role in dynamic control, changing the goal and restrictions paves the way for Multi-Objective-Optimization. As most structural designers today use commercial software such as FE-Codes or CAE systems with integrated simulation modules, ways of integrating Bionic Optimization into these software packages are outlined and examples of typical systems and typical optimization approaches are presented. The closing section focuses on an overview and outlook on reliable and robust as well as on Multi-Objective-Optimization, including discussions of current and upcoming research topics in the field concerning a unified theory for handling stochastic design processes.
Named after the 40th governor of Louisiana, the Huey P. Long Bridge, just outside of New Orleans in Jefferson Parish, is the longest railroad bridge in the United States. For 15 years after it opened in 1935, it was the longest railroad bridge in the world. Initially conceived in 1892, the "Huey P." was the first bridge to span the deep-draft navigation channel of the lower Mississippi River, opening the path for a southern transcontinental railroad. The highway and pedestrian portions of the bridge provided additional transport, which previously had only been available by ferry. New Orleans and its surrounding regions grew in population and economic importance as the publicly owned bridge connected the Port of New Orleans to the rest of the United States through six Class I railroads. The Huey P. continues to function in its original, now undersized, capacity. In April 2006, the state began a widening of the bridge to double its automobile lanes from 18 feet to 43 feet. In September 2012, the American Society of Civil Engineers dedicated the Huey P. Long Bridge as a Historic Civil Engineering Landmark.

This book provides a new, necessary and valuable approach to the consideration of risk in underground engineering projects constructed within rock masses. There are Chapters on uncertainty and risk, rock engineering systems, rock fractures and rock stress, the design of a repository for radioactive waste, plus two major case examples relating to the headrace tunnels and caverns for a hydroelectric project. These Chapters highlight in detail the authors' new rock engineering risk approach, especially how monitoring during construction can significantly reduce the construction risks. The book is particularly timely given the current increasing emphasis on geo-engineering safety, accountability and sustainability-which requires stricter attention to risk and greater reliability than ever before. Written by two eminent authors, the two most recent past-Presidents of the International Society for Rock Mechanics (ISRM), this modern and well-illustrated guide on Rock Engineering Risk complements the authors' previous 2011 book on Rock Engineering Design, also published by Taylor & Francis. The book will benefit engineers, contractors, clients, researchers, lecturers and advanced students who are concerned with rock engineering projects in civil, mining, geological and construction engineering worldwide.
A study on rock mechanics in salt mining, this work includes coverage of the exploration and opening of salt mining, deformation and failure of the salt, strata mechanics and control for different mining systems, and stability analyses of the mine structures.
This short monograph and timely practitioner guide offers a comprehensive theoretical background and a design procedure for hoop--wrapped, composite gas cylinders. It gives a fundamental insight into the effects of process variables and how they interact, allowing a predictive approach to design and enabling test results to be assessed in a more meaningful way. The theory described is also generally applicable to all kinds of internally pressurized cylindrical pressure vessels and pipes where hoop reinforcement is an integral part of the design. Designing high--pressure gas cylinders using composites is a relatively new and rapidly developing technology, exploiting recent advances in high--strength lightweight synthetic fibres. Traditionally, only metals have been used, but clearly weight is a major consideration in the efficiency of gas cylinders. Lightweight composite cylinders offer considerable advantages over heavier all--metal alternatives, provided concerns over safety can be allayed. Manufacture of composite gas cylinders has relied primarily on costly 'design by testing' to ensure that stringent safety standards are met. With new European and International Standards backed by recently introduced legislation Hoop--wrapped Composite Internally Pressurized Cylinders -- Development and Application of a Design Theory provides the industry with a much--needed, reliable, and transparent methodology for the design of hoop--wrapped, composite gas cylinders.
Throughout history, the need to cross the changing British landscape has always driven innovation. Natural valleys, rivers and mountainous features required the construction of bridges in ancient times to expand our horizons, transport goods and, ultimately, conquer all corners of our island nation. Since then, with the development of technology, bridges have become not only practical structures for people and their possessions, but also prominent icons of our railway network, our reliance on motor vehicles and a desire to connect the country's settlements and communities with one another. Today, Britain has bridges spanning not only many of its rivers, but much of its history. Each age brought new designs and engineering prowess, celebrated most proudly during the Industrial Revolution. This book admires some of the best, from the world-renowned to the minor and the modest.
Imagine you woke up one morning to find everything created by engineers had disappeared. What would you see?
No cars, no houses; no phones, bridges or roads. No tunnels under tidal rivers, no soaring skyscrapers. The impact that engineering has had on the human experience is undeniable, but it is also often invisible.
In BUILT, structural engineer Roma Agrawal takes a unique look at how construction has evolved from the mud huts of our ancestors to skyscrapers of steel that reach hundreds of metres into the sky. She unearths how engineers have tunnelled through kilometres of solid mountains; how they've bridged across the widest and deepest of rivers, and tamed Nature's precious - and elusive - water resources. She tells vivid tales of the visionaries who created the groundbreaking materials in the Pantheon's record-holding concrete dome and the frame of the record-breaking Eiffel Tower. Through the lens of an engineer, Roma examines tragedies like the collapse of the Quebec Bridge, highlighting the precarious task of ensuring people's safety they hold at every step.
With colourful stories of her life-long fascination with buildings - and her own hand-drawn illustrations - Roma reveals the extraordinary secret lives of structures.
This book enables the student to master the methods of analysis of isostatic and hyperstatic structures.

This procedure provides an insight into the methods of analysis of the structures.
Nonlinear Structural Dynamics Using FE Methods emphasises fundamental mechanics principles and outlines a modern approach to understanding structural dynamics. This will be useful to practising engineers but also students who will find advanced topics presented in an accessible manner. The book successfully presents the fundamentals of structural dynamics and infuses them with finite element (FE) methods. First, the author establishes and develops mechanics principles that are basic enough to form the foundations of FE methods. Second, the book presents specific computer procedures to implement FE methods so that general problems can be 'solved' - that is, responses can be produced given the loads, initial conditions and so on. Finally, the book introduces methods of analyses to leverage and expand the FE solutions.

Contributing to an area which is the subject of intensive research and development, this book offers both theoretical principles and feasibility studies for a number of SHM techniques. Key features: * Takes a multidisciplinary approach and provides a comprehensive review of main SHM techniques * Presents real case studies and practical application of techniques for damage detection in different types of structures * Presents a number of new/novel data processing algorithms * Demonstrates real operating prototypes Advanced Structural Damage Detection: From Theory to Engineering Applications is a comprehensive reference for researchers and engineers and is a useful source of information for graduate students in mechanical and civil engineering
The book introduces all the aspects needed for the safe and economic design and analysis of connections in modern steel structures. This is not treated according to any specific standard but making comparison among the different norms and methodologies used in the engineering practice, e.g. Eurocode, AISC, DIN, BS. Several examples are solved and illustrated in detail, giving the reader all the tools necessary to tackle also complex connection design problems. The book is introductory but also very helpful to advanced and specialist audiences because it covers a large variety of practice demands for connection design. Parts that are not taken to an advanced level are seismic design, welds, interaction with other materials (concrete, wood), and cold formed connections.
Your guide to the design and construction of foundations on expansive soils Foundation Engineering for Expansive Soils fills a significant gap in the current literature by presenting coverage of the design and construction of foundations for expansive soils. Written by an expert author team with nearly 70 years of combined industry experience, this important new work is the only modern guide to the subject, describing proven methods for identifying and analyzing expansive soils and developing foundation designs appropriate for specific locations. Expansive soils are found worldwide and are the leading cause of damage to structural roads. The primary problem that arises with regard to expansive soils is that deformations are significantly greater than in non-expansive soils and the size and direction of the deformations are difficult to predict. Now, Foundation Engineering for Expansive Soils gives engineers and contractors coverage of this subject from a design perspective, rather than a theoretical one. Plus, they'll have access to case studies covering the design and construction of foundations on expansive salts from both commercial and residential projects. * Provides a succinct introduction to the basics of expansive soils and their threats * Includes information on both shallow and deep foundation design * Profiles soil remediation techniques, backed-up with numerous case studies * Covers the most commonly used laboratory tests and site investigation techniques used for establishing the physical properties of expansive soils If you're a practicing civil engineer, geotechnical engineer or contractor, geologist, structural engineer, or an upper-level undergraduate or graduate student of one of these disciplines, Foundation Engineering for Expansive Soils is a must-have addition to your library of resources.
