Preface
As with a well-cut diamond, project success has many facets that work in unison to create a brilliant result; and as with a well-cut diamond, some facets contribute far more to the overall impression than others. This book is focused on a major facet of project success, effective project time management, which underpins the cost-effective use of resources and contributes to achieving a time- and cost-efficient project without compromising quality, safety or risk management objectives.
This book is the second edition (retitled to better reflect its objective) of CIOB's highly successful Guide to Good Practice in the Management of Time in Complex Projects,1 first published in 2011. Since 2011, leading authorities globally have increasingly recognised ‘schedule is king’2 and have placed increased emphasis on the proactive management of time, using dynamic modelling, as a precursor to project success. In keeping with this theme, the USA Government Accountability Office (GAO) published its Schedule Assessment Guide: Best Practices for Project Schedules in 20153 to complement its well-regarded Cost Estimating and Assessment Guide.4 The CIOB has also updated its Complex Projects Contract, 20135 as the Time and Cost Management Contract suite 2015,6 including back-to-back Consultancy Appointment and Subcontract, and many other standards and guides requiring effective project time management have also been updated or published since the first edition of the Guide was released.
This Guide to Good Practice in the Management of Time in Major Projects – Dynamic Time Modelling does not seek to duplicate these standards; rather it provides the practical and rigorous framework needed to guide scheduling practice to achieve the objectives defined by these standards. Applying the guidance contained in this book will offer any project team the best way to achieve the effective management of the time available to complete their project, conform to recognised good practices, and consequently create the best opportunity for a successful project outcome.
Introduction to Second Edition
The Guide to Time Management in Major Projects – Dynamic Time Modelling (the Guide) is a revised edition of what was previously the CIOB's Guide to Good Practice in the Management of Time in Complex Projects, published in 2011.1 The name has been changed to reflect more clearly the core strengths of the Guide and its application to the management of major projects; however, whilst the Guide is focused on construction and engineering projects, the concepts and procedures can be adapted for use in any type of project.
The Guide is a practical treatise on the processes to be followed and standards to be achieved in the effective management of time. Subject to the amendment of existing forms of contract to remove inconsistencies, the Guide can be used in any jurisdiction, under any form of contract, with any type of project.
The Guide promotes competence in critical path network modelling, resource allocation and productivity analysis by the use of a dynamic time model (DTM).2 The Guide does not recommend a single density,3 static baseline target programme, but requires a dynamic critical path network, in differing densities, updated and revised on the rolling wave principle which constantly predicts the currently attainable completion date, sectional completion dates and key dates as a result of the current sequencing.
Although the Guide is not based upon any contractual regime or procurement process, the CIOB's ‘Time and Cost Management Contract’ suite (2015)4 has been written for use with the Guide to provide a uniform approach to cost and time risk management from initiation to completion of major building and engineering projects in accordance with the Guide's recommendations.
