Delayed completion affects IT, process plant, oil and gas, civil engineering, shipbuilding and marine work contracts. In fact it affects all industries in all countries and the bigger the project, the more damage delayed completion causes to costs, to reputation and sometimes, even to the survival of the contracting parties themselves.

In simple projects, time can be managed intuitively by any reasonably competent person, but complex projects cannot and a more analytical approach is necessary if the project is to succeed. Although much has been written about how to apportion liability for delay after a project has gone wrong there was, until recently, no guidance on how to manage time pro-actively and effectively on complex projects.

In 2008, the CIOB embarked upon a 5-year strategy to provide standards, education, training and accreditation in time management. The first stage, this Guide to Good Practice in Managing Time in Complex Projects, sets down the process and standards to be achieved in preparing and managing the time model.

As a handbook for practitioners it uses logical step by step procedures and examples from inception and risk appraisal, through design and construction to testing and commissioning, to show how an effective and dynamic time model can be used to manage the risk of delay to completion of construction projects.

Glossary of terms.


"The Guide will benefit not only the construction industry, but also other sectors such as the oil services, process and energy Industries." (Project Manager Today, 1 January 2011)

"A new guide to help construction professionals keep control of timescales on complex projects has been published by the Chartered Institute of Building and Wiley Blackwell." (Self Build & Design, 1 March 2011)

"The guide will be beneficial to academics and students learning the basics of time management, but it could also become a reference document for all parties involved in the delivery of complex projects, including senior managers and clients". (Construction Manager, 1 January 2011)

"This new handbook uses a logical step by step approach to show how an effective time model can be used to manage the risk of delay to completion on construction projects. It demonstrates procedures and examples from inception and risk appraisal, through design and construction, to testing and commissioning that show practitioners the logical procedures to use". (Construction Now Daily, 4 January 2011)

  • provides guidance for the scheduling of increasingly complex construction projects, ensuring systematic documentation and quality control
  • each stage of project scheduling is discussed, with examples of specimen forms, checklists and typical documentation provided
  • written by the CIOB, whose other guides have become industry standard documents
