"This book provides valuable guidance on how to save time and therefore money by avoiding -- or at least coping -- with the factors that cause expensive delays, or disruption on construction and engineering projects. Certainly its sage advice on dispute resolution should prove indispensable to everyone from architects and construction lawyers to project managers and quantity surveyors." (Flickr.com, 7 August 2015)
