Delay and disruption often impacts entire projects and is prevalent throughout the entire construction and engineering industries - no project or construction professional is immune to the effects. This book is aimed at any construction professional anywhere in the world who is involved in preparing, assessing, managing and/or deciding issues concerning the assessment of additional time to complete the work, and also additional payment for delay and/or disruption to the progress of a construction or engineering project. Delay and disruption is endemic in the construction industry and leads to time and cost overruns. It is therefore essential that delays and/or disruptions are identified early so that corrective action can be taken. However, when delay and/or disruption actually occurs, the issue of quantifying the period of any delay, the effects of disruption, and the quantification of the resulting loss during, and especially at the end, of a project is complicated.

Now in its sixth edition, Delay and Disruption in Construction Contracts retains its position as foremost guide to the complex issues arising in the course of construction, with robustly-updated content throughout and the addition of several new chapters with focus on such topics as standard form provisions for recovery of loss or expense, and Chinese and Peruvian construction law. Expertly covering the manner in which delay and disruption should be considered at each stage of a construction project, from inception to completion and beyond, this book includes: Insight from an international team of specialist advisory editors Comparative analysis of the law in this field in Australia, Canada, England and Wales, Hong Kong, Ireland, New Zealand, the United States and in civil law jurisdictions Commentary upon, and comparison of, standard forms from Australia, Ireland, New Zealand, the United Kingdom, USA and elsewhere, including two major new forms Chapters on adjudication, dispute boards and the civil law dynamic Extensive coverage of Building Information Modelling New chapters on Chinese, Nordic, Peruvian, Singaporean and Malaysian construction law New in-depth discussion of the JCT 2016 suite Updated case law, linked directly to the principles explained in the text. This book is an essential reference for any lawyer, dispute resolver, project manager, architect, engineer, contractor, or academic involved in the construction industry.

The most significant unanticipated costs on many construction projects are the financial impacts associated with delay and disruption to the works. Assessing these, and establishing a causal link from each delay event to its effect, contractual liability and the damages experienced as a direct result of each event, can be difficult and complex. This book is a practical guide to the process of delay analysis and includes an in-depth review of the primary methods of delay analysis, together with the assumptions that underlie the precise calculations required in any quantitative delay analysis. The techniques discussed can be used on projects of any size, under all forms of construction contract, both domestic and international. The authors discuss not only delay analysis techniques, but also their appropriateness under given circumstances, demonstrating how combined approaches may be applied where necessary. They also consider problematic issues including ‘who owns the float’, concurrent delay, early completion programmes, and disruption. The book has been brought fully up to date, including references to the latest publications from the CIOB, AACEI and SCL, as well as current case law. Broad in scope, the book discusses the different delay analysis approaches likely to be encountered on national and international projects, and features practical worked examples and case studies demonstrating the techniques commonly used by experienced practitioners. This is an invaluable resource to programmers and schedulers, delay analysts, contractors, architects, engineers and surveyors. It will also be of interest to clients’ professional advisors managing extension of time or delay claims, as well as construction lawyers who require a better understanding of the underlying assumptions on which many quantitative delay analyses are based. Reviews of First Edition "John Keane and Anthony Caletka are pukka analysts in that tricky area of delays, programming and extension of time. I highly recommend their book Delay Analysis in Construction Contracts. Buy the book." (Building Magazine, February 2009) "The book′s stated purpose is to provide a practical guide for those interested in schedule delay analysis. It provides a good in–depth review of the most common delay analysis techniques.... An excellent book, full of practical tips for the reader and very timely in its publication. It is well worth the cost and a good read for anyone involved in schedule delay analysis." (Cost Engineering, February 2009) It achieves in spades its stated aim of being a practical guide for contractors, contract administrators, programmers and delay analysts, as well as construction lawyers who require a better understanding of the underlying assumptions on which many quantitative delay analyses are based. (Construction Law Journal, 2009)

Standard ANSI/ASCE/CI 67-17 presents 35 guiding principles that can be used on construction projects to assess responsibility for delays and to calculate associated damages.

Cumulative impacts on construction projects remain largely an ill-defined concept. A more thorough understanding of cumulative impacts as defined by the construction industry and courts and boards will aid the contractor in preparing its damages and proving causation. The information herein provides a blueprint for the contractor seeking to recover costs that result from disruption and the cumulative impact of changes. Conversely, information is also provided that can be used by the owner to identify weaknesses in the contractor's claim submittal to better defend against a cumulative impact claim.
