This work has long been the foundational Primer for attorneys, forensics consultants, owners, construction managers, contractors and design professionals who are dealing with construction claims. It broadly covers delay (by both owner and contractor), disruption, acceleration, differing site conditions, scope change, termination, claims against professionals, equipment costs, overhead including Eichleay, and lost profits. Other books dig deep into any one of these topics (William Schwartzkopf on calculating productivity, for example) but this one offers the basics on all of them; well researched, annotated with plenty of quotations from case cites.
I've taught over 300 public one-day classes on these topics and have recommended this book to every one of the 5,000+ attendees. Every construction-related office should have a copy. As long as we do Design-Bid-Build projects, this work will have a place on our reference shelves. And when we've finally moved fully to Design-Build, Lean and Integrated Project Delivery, we'll keep a copy around to remind ourselves of how complicated our construction lives once were.
Cushman, who passed recently, edited 36 books still sold on Amazon, every one an authoritative, but very readable treatment of its subject. His name on a legal tome is a green light to the lay reader that s/he can access and understand the material and be a better client; knowing their attorneys are likely consulting Cushman works as well.
