The degree of danger in the atmosphere of a hazardous location needs to be determined prior to selecting an acceptable electrical equipment installation. If maximum safety is the predominant factor in determining the type of electrical installations, the cost of electrical equipment will be extremely high. If low cost of electrical installation is the predominant factor, safety to personnel and equipment may be unacceptably low. It is, therefore, necessary to find a point of balance at which the cost and safety requirements are both satisfied and acceptable.

The intent of this book is to provide an in-depth understanding of the factors that influence the classification of a hazardous location. One factor, in combination with one or more other factors, will have an impact on the level of danger and its hazardous boundaries. These factors and their influences are explained in detail, and once their impact is understood, the classification of a hazardous location becomes a straightforward procedure.

The intent of the classification of a hazardous location is to provide safety for personnel and equipment. The intent is also to achieve an economical electrical installation which will provide an acceptable level of safety for personnel and equipment at the lowest possible cost. To accomplish this, it is necessary to analyze in detail the environmental conditions of the location and the characteristics of the source of hazard. The engineer who is involved in preparing the area classification must understand all of the details which will have an impact on his decision to classify the area Division 1, Division 2, or Non-hazardous. Without the knowledge of the environmental conditions,and the characteristics of the source of hazard, he most certainly will give the location a safety level much too high, which is not economically justified, or a level too low, which is unsafe. This approach must be avoided.

In nine out of ten cases, a hazardous location is classified much too conservatively. The reason for this conservative approach is a lack of knowledge and a misunderstanding of the actual concept of safety and danger.

The application of the information in this book is mainly for flammable liquids, vapors, and gases that are processed, handled, stored, and/or transferred.

In 1999, a suite of three new conditions of contract was published by FIDIC, following the basic structure and wording harmonised and updated around the previous FIDIC Design-Build and Turnkey Contract (the 1992 ''Orange Book''). These conditions, known as the ''FIDIC rainbow, were the Conditions of C- tract for: l Construction, the so-called Red Book, for works designed by the Employer l Plant and Design-Build, the so-called Yellow Book, for works designed by the Contractor l EPC/Turnkey Projects, the so-called Silver Book, for works designed by the Contractor The ?rst is intended for construction works where the Employer is responsible for the design, as for per the previous so-called Red Book 4th Edition (1987), with an important role for the Engineer. The other two conditions of contract are intended for situations when the Contractor is responsible for the design. The Plant and Design-Build Contract has the traditional Engineer while the EPC/Turnkey Contract has a two-party arran- ment, generally with an Employer's Representative as one of the parties.

Improved geospatial instrumentation and technology such as in laser scanning has now resulted in millions of data being collected, e.g., point clouds. It is in realization that such huge amount of data requires efficient and robust mathematical solutions that this third edition of the book extends the second edition by introducing three new chapters: Robust parameter estimation, Multiobjective optimization and Symbolic regression. Furthermore, the linear homotopy chapter is expanded to include nonlinear homotopy. These disciplines are discussed first in the theoretical part of the book before illustrating their geospatial applications in the applications chapters where numerous numerical examples are presented. The renewed electronic supplement contains these new theoretical and practical topics, with the corresponding Mathematica statements and functions supporting their computations introduced and applied. This third edition is renamed in light of these technological advancements.

The Finite Element Method, shortly FEM, is a widely used computational tool in structural engineering. For basic design purposes it usually suf ces to apply a linear-elastic analysis. Only for special structures and for forensic investigations the analyst need to apply more advanced features like plasticity and cracking to account for material nonlinearities, or nonlinear relations between strains and displacements for geometrical nonlinearity to account for buckling. Advanced analysis techniques may also be necessary if we have to judge the remaining structural capacity of aging structures. In this book we will abstain from such special cases and focus on everyday jobs. Our goal is the worldwide everyday use of linear-elastic analysis, and dimensioning on basis of these elastic computations. We cover steel and concrete structures, though attention to structural concrete prevails. Structural engineers have access to powerful FEM packages and apply them intensively. Experience makes clear that often they do not understand the software that they are using. This book aims to be a bridge between the software world and structural engineering. Many problems are related to the correct input data and the proper interpretation and handling of output. The book is neither a text on the Finite Element Method, nor a user manual for the software packages. Rather it aims to be a guide to understanding and handling the results gained by such software. We purposely restrict ourselves to structure types which frequently occur in practise.

The book presents the development of the Construction Quality Assessment System (CONQUAS), Singapore's de facto quality performance measurement system, explains the application of the Quality Management System (QMS) to manage CONQUAS and identifies 33 critical success factors (CSFs) for achieving high CONQUAS scores. Through CONQUAS, the reader benefits from understanding how the Singapore government developed and implemented the first objective system for measuring what many building professionals have perceived to be elusive quality standards in the construction industry. The book presents both the theoretical concepts as well as the practical aspects to achieving strategic Project Quality Management that is anchored on the CSFs to building best practices. To realistically reflect the practical aspects and challenging issues faced by stakeholders in the construction industry, questionnaire surveys were conducted with building professionals to distinguish the importance level and extent of adoption of the 33 CSFs (identified from a comprehensive review of the extant literature) in influencing and affecting the achievement of high CONQUAS scores. These were further anchored by in-depth interviews with quality experts in the Singapore construction industry to provide a better understanding of issues relating to strategic Project Quality Management. Collectively, the empirical findings collated from the building professionals suggest that while the CSFs identified are known tenets of quality, these were still not being followed in their totality. A further case study was conducted through a formal set of in-depth interviews with the quality assurance team of a construction company who has direct involvement before, during and after their tremendous improvements in the CONQUAS scores attained. The strength of this book therefore represents a true account and reflections of real-life practices and experiences in the construction industry for contractors, quality managers and policy-makers to learn from. Although the context of this book relates to the Singapore experience, the lessons and recommendations are equally relevant and applicable to the global construction industry in both the developing and developed countries whose stakeholders (in both the public and private sectors) wish to understand how CONQUAS works, and how the CSFs identified can likewise be implemented for strategic Project Quality Management to building best practices. The book is therefore of interests to researchers, academia and practitioners in the construction industry as well as in other sectors of the economy (in Singapore and other countries) where learning points may be used for enhancing project quality management for buildings.

Throughout the past few years, there has been extensive research done on structural design in terms of optimization methods or problem formulation. But, much of this attention has been on the linear elastic structural behavior, under static loading condition. Such a focus has left researchers scratching their heads as it has led to vulnerable structural configurations. What researchers have left out of the equation is the element of seismic loading. It is essential for researchers to take this into account in order to develop earthquake resistant real-world structures. Structural Seismic Design Optimization and Earthquake Engineering: Formulations and Applications focuses on the research around earthquake engineering, in particular, the field of implementation of optimization algorithms in earthquake engineering problems. Topics discussed within this book include, but are not limited to, simulation issues for the accurate prediction of the seismic response of structures, design optimization procedures, soft computing applications, and other important advancements in seismic analysis and design where optimization algorithms can be implemented. Readers will discover that this book provides relevant theoretical frameworks in order to enhance their learning on earthquake engineering as it deals with the latest research findings and their practical implementations, as well as new formulations and solutions.

The construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources. Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new "green" design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined. Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.
