What exactly is this thing called commissioning? Answering this fundamental question is the objective of this book. Fifteen years after the first national commissioning conference, there still seems to be a need for a consolidated source of information on the basics of building commissioning. This book attempts to be that source, and to make the fundamentals of commissioning accessible to all interested parties—to building owners and operators, to architects and engineers about to embark on commissioning efforts, and to others (such as users or suppliers) who may be called on to join the commissioning teamfor a particular project. This book is intended for anyone looking for ‘‘Commissioning 101.’’ As demand for green, carbon-neutral, high-performance buildings increases, so should the numbers of people seeking to understand commissioning.
Principles of Building Commissioning attempts to clarify the underlying philosophy of commissioning: the why, what, when, and who of this process. It maps out the territory of commissioning, outlines its defining characteristics, explains its flow of processes, and demystifies its documentation. This book is very much shaped by the ASHRAE Guideline 0 view of the world of commissioning.

The book collects the latest research on both contractual and conceptual collaborative practices in construction. It identifies common problems faced by the industry and draws out practical implications.
Construction projects are increasingly run in ways that undermine the traditional boundary of the firm and sometimes also the definition of the project coalition. This poses challenges for construction firms whose clients demand ever increasing performance improvements as well as those firms who want to improve their strategies for greater collaboration to give themselves competitive advantage.
The editors identify three main themes: collaborative relationships, operating both in frameworks and within networks of contacts, e.g. relational contracting in partnering, supply chain management and other procurement-driven initiatives.
The second theme is frameworks, both contractual frameworks binding parties together over a series of contracts, and conceptual frameworks used to develop future performance improvement arising from the proactive strategies of firms.
The third theme is the network of relationships that supports individuals and firms within the project coalition in delivering services and adding value to improve performance. These networks define the investment and incentives supporting the inter-firm and intra-firm relationships, as well as the formal contractual conditions through which such incentives flow. Networks of information exchange define the structure of the activity and help predict organisational configurations for successful project outcomes.

Author: David Yung | Size: 2.17 MB | Format:PDF | Publisher: John Wiley & Sons | Year: 2008 | pages: 248 | ISBN: 0470854099
Yung, one of internationally recognised expert on the subject of fire risk assessment, introduces the basic principles and techniques that help the reader to understand the various methodologies that are currently in place or being proposed by different organisations. Through his illustration of basic principles and techniques he enables the reader to conduct their own fire risk assessments. He demonstrates how the probabilities of fire scenarios are assessed based on the probabilities of success and failure of fire protection measures that are in place. He also shows how the consequences of fire scenarios are assessed based on the intensity and speed of fire and smoke spread, the probability and speed of occupant response and evacuation, and the effectiveness and speed of fire department response and rescue efforts.

Predictive and Optimised Life Cycle Management: Buildings and Infrastructure
Author: Edited by Asko Sarja | Size: 6.5 MB | Format:PDF | Publisher: Routledge | Year: 2006 | pages: 688 | ISBN: 0415353939
Predictive and Optimised Life-Cycle Management sets out methodologies to meet the demands of the current trend towards sustainable civil engineering and building.
Encompassing all aspects of construction practice, from design through to demolition and the recycling of materials, Sarja provides tools for optimal property-value protection, including a description of an integrated and predictive Life-Cycle Maintenance and Management Planning System (LMS), which employs a wide range of techniques.
Clear and practical, this guide provides effective methodology required to change a reactive system of management to a predictive one, which will benefit practitioners and students involved in construction, from the architect to local and government authorities; from design engineers to facility managers.

Adhesive bonding is increasingly regarded as a cost effective and effectual way to join mechanical structures. This book reviews recent improvements in adhesive bonding and their wide-ranging potential in structural engineering. Part one discusses methods for selecting the correct adhesive. The second set of chapters discusses the various types of adherents. A third set of chapters analyses methods and techniques for joint design. The final chapters give useful and practical insight into the problems and solutions of adhesive bonding in a variety of hostile environments such as chemical, wet, and extreme temperatures.

Cumulative damage of welded joints >> By T R Gurney, formerly TWI, UK
Author: T R Gurney, formerly TWI, UK | Size: 3.3 MB | Format:PDF | Publisher: Woodhead Publishing Limited | Year: August 2006 | pages: 457 | ISBN: ISBN 1 85573 938 0 ISBN-13: 978 1 85573 938 3
- covers the wealth of research in the field of fatigue strength and its role in the design and manufacture of welded components
- invaluable reference source for welding engineers, supervisors, inspection personnel and designers
Fatigue is a mechanism of failure which involves the formation and growth of cracks under the action of repeated stresses. Ultimately, a crack may propagate to such an extent that total fracture of the member may occur. To avoid fatigue it is essential to design the structure with inherent fatigue strength. However, fatigue strength for variable amplitude loading is not a constant material property and any calculations are necessarily built on a number of assumptions. Cumulative damage of welded joints explores the wealth of research in this important field and its implications for the design and manufacture of welded components.
After an Introduction, chapter two introduces the constant amplitude database, which contains results obtained in test conditions and which forms the basis of the basic S-N curves for various types of joint. Chapter three discusses the influence of residual stresses which can have a marked effect on fatigue behaviour. Chapter four explores variable amplitude loading and the problem of how information from laboratory tests, obtained under constant amplitude conditions, can be applied to the design of structures for service conditions. This problem is further investigated in the next chapter which is devoted to two and three level load testing. Chapters six, seven and eight look at the influence that the variety of variable loading spectra can have on fatigue strength, whether narrow or wide band loading or cycles of small stress range. Taking all of this knowledge, chapter nine discusses structure designs.
Cumulative damage of welded joints is a comprehensive source of invaluable information for welding engineers, supervisors, inspection personnel and designers. It will also be of great interest for academics working in the fields of structural and mechanical engineering.
About the author
Dr Gurney worked at TWI (formerly the British Welding Research Association) for over thirty years, during which time his primary interest was in the fatigue of welded structures. He has written or co-authored over fifty papers throughout his career.
