This book … adds to the impressive ‘legacy’ of learning which is still emerging from the successful delivery of the London 2012 construction programme. The authors combine the reforming zeal of a champion for change, who was there every step of the way, with academic rigour, and the result is delivered with impressive passion and commitment to the topic … All spenders and suppliers need to read this, to understand how conventional understandings of procurement fall so dramatically short when applied to high value-high risk acquisitions, which invariably is what large construction projects represent.’ Don Ward, Chief Executive, Constructing Excellence, UK Successful construction is often attributed to one or more aspects of the delivery process from good planning, design and clever engineering to efficient project management and quality construction. Before any of these disciplines can begin, they all require some form of procurement to select the team or supply chain to meet a client’s or a project’s specific requirements. The concept of PSE – Purchase and Supplier Engineering – originated in the procurement of the construction and infrastructure required to stage the 30th Olympiad in London during 2012. At the time of writing PSE has successfully delivered almost £25bn of public procurement meeting client and project requirements and without legal challenge. The construction of the venues and infrastructure needed to stage London 2012 was such a resounding success that it boosted not only the reputation of the UK construction industry but also the confidence of the UK population in the country’s ability to organise, build and run a major international event. Its success has been lauded as something from which clients and industry could learn. The ODA has established a comprehensive and informative body of evidence as part of a Learning Legacy. While the ODA is well aware of the many elements of the procurement and supply chain management, the complete end to end concept of how the Olympic supply chain procurements were managed has until now not been captured. For example, how does one buy the stage for an Olympic Games? How does one manage the details of thousands of contracts and the many firms of contractors, subcontractors and material suppliers and ensure that no one organisation adversely affects any other to the detriment of the programme? How are a client’s requirements beyond those of the capital asset realised as part of the investment? How does one measure programme exposure, or manage performance? How does one measure capacity and the ability of firms to cope with the work and manage the risks involved? Programme Procurement in Construction: Learning from London 2012 covers the planning and preparation of a programme’s procurement processes from understanding and developing the client’s requirements, to monitoring performance based on the benchmarks contractors set out in their own tender submissions. The emphasis is on a close attention to detail to avoid surprises, while keeping a focus on the total programme. Purchase and Supplier Engineering provides an overview of managing the interest of firms in participating and the resulting capacity and workloads of all suppliers, including the main contractors and the critical subcontractors and material suppliers. Offering techniques, tips and lessons learnt from the implementation of PSE on London 2012 and Crossrail, this book is aimed at public and private sector clien
Introduction to Computational Contact Mechanics. A Geometrical Approach
Introduction to Computational Contact Mechanics: A Geometrical Approach covers the fundamentals of computational contact mechanics and focuses on its practical implementation. Part one of this textbook focuses on the underlying theory and covers essential information about differential geometry and mathematical methods which are necessary to build the computational algorithm independently from other courses in mechanics. The geometrically exact theory for the computational contact mechanics is described in step-by-step manner, using examples of strict derivation from a mathematical point of view. The final goal of the theory is to construct in the independent approximation form /so-called covariant form, including application to high-order and isogeometric finite elements. The second part of a book is a practical guide for programming of contact elements and is written in such a way that makes it easy for a programmer to implement using any programming language. All programming examples are accompanied by a set of verification examples allowing the user to learn the research verification technique, essential for the computational contact analysis. Key features: Covers the fundamentals of computational contact mechanics Covers practical programming, verification and analysis of contact problems Presents the geometrically exact theory for computational contact mechanics Describes algorithms used in well-known finite element software packages Describes modeling of forces as an inverse contact algorithm Includes practical exercises Contains unique verification examples such as the generalized Euler formula for a rope on a surface, and the impact problem and verification of thå percussion center Accompanied by a website hosting software Introduction to Computational Contact Mechanics: A Geometrical Approach is an ideal textbook for graduates and senior undergraduates, and is also a useful reference for researchers and practitioners working in computational mechanics.
Constructing Futures. Industry leaders and futures thinking in construction
There is growing interest in future scenario planning of the construction industry but a disconnect between thinking about the future at the policy-making level and implementing real change. Constructing Futures: industry leaders and futures thinking in construction takes a thematic approach to the future of the UK construction industry by presenting the results of a series of in-depth interviews conducted with leading construction figures and structuring this material into chapters addressing the key contemporary issues in the industry. These high-profile figures are drawn from a wide range of stakeholder groups representing the realities of construction, including architects, client organisations (public-sector and private-sector), consultants, contractors, developers, lobby groups with special interests, policy makers, professional institutions, and trade unions. A total of 15 influential figures were interviewed for the book, from Sir Michael Latham and Bob White to Wayne Hemmingway and Kevin McCloud. Part One looks to the past by reviewing a series of foresight studies undertaken of the construction industry and re-presenting stories of our interviewees' lives to explain the development of leadership in the context of the construction industry. In Part Two, the authors look at the present and discuss two fundamental issues: sustainable development and governance of the construction industry. In Part Three the book concludes with an afterthought for the future, highlighting key lessons learnt putting forward a series of research questions derived from this scholarly reflection of 'futures thinking' in construction. Throughout, the authors juxtapose the views of the 15 influential figures interviewed with a review of the salient points found in the relevant and authoritative sources of theoretical literature, both in the mainstream literature and the field of construction management. This allows the reader to benefit from the practical insights of those interviews whilst gaining a rapid understanding of the key debates of the theoretical subject under scrutiny.

Steel Structures. Design using FEM
This book presents the design of steel structures using finite element methods (FEM) according to the current state of the art in Germany and the rest of Europe. After a short introduction on the basics of the design, this book illustrates the FEM with a focus on internal forces, displacements, critical loads and modal shapes. Next to finite element procedures for linear calculations considering the stress states of normal force, biaxial bending and warping torsion, non-linear calculations and the stability cases of flexural buckling, lateral torsional buckling and plate buckling are concentrated on significantly. In this context, design procedures for stability according to the standard Eurocode 3 is introduced and discussed. In addition, important fundamental issues are covered, such as the determination of cross-section properties as well as the elastic and plastic cross-section resistance. Complementary, finite element procedures for cross sections are dealt with, which will have an increasing importance in future. This book has evolved within the teaching activities of the authors in the lecture Computer-oriented Design of Steel Structures on the Master?s Program Computational Engineering at the University of Bochum. It covers the total variety of demands needed to be discussed for the safe, economic and modern design of steel structures.

Failed Bridges. Case Studies, Causes and Consequences
When bridges fail, often with loss of human life, those involved may be unwilling to speak openly about the cause. Yet it is possible to learn from mistakes. The lessons gained lead to greater safety and are a source of innovation. This book contains a systematic, unprecedented overview of more than 400 bridge failures assigned to the time of their occurrence in the bridges' life cycle and to the releasing events. Primary causes are identified. Many of the cases investigated are published here for the first time and previous interpretations are shown to be incomplete or incorrect. A catalogue of rules that can help to avoid future mistakes in design analysis, planning and erection is included. A lifetime's work brilliantly compiled and courageously presented – a wealth of knowledge and experience for every structural engineer.
Driving Simulation
Passive and active safety systems (ABS, ESP, safety belts, airbags, etc.) represent a major advance in terms of safety in motoring. They are increasingly developed and installed in cars and are beginning to appear in twowheelers. It is clear that these systems have proven efficient, although there is no information about their actual operation by current users. The authors of this book present a state of the art on safety systems and assistance to driving and their two-wheeled counterparts. The main components constituting a driving simulator are described, followed by a classification of robotic architectures. Then, a literature review on driving simulators and two-wheeled vehicles is presented. The aim of the book is to point out the differences of perspectives between motor vehicles and motorcycles to identify relevant indicators to help in choosing the mechanical architecture of the motorcycle simulator and appropriate controls. Contents 1. Driving Simulation. 2. Architecture of Driving Simulators. 3. Dynamics of Two-Wheeled Vehicles. 4. Two-Wheeled Riding Simulator: From Design to Control.
