The CONSULTING ENGINEER'S "Guidebook" is an excerpted and extended version of the new book The "Complete Guide" to CONSULTING ENGINEERING by John D. Gaskell, Retired Professional Engineer. It is the result of requests from many readers to narrow the focus to the goals of: Becoming an "outstanding" consulting engineer. Gaining a reputation as an "expert" in their specialty; and Obtaining the engineering "management skills" needed to advance their career and make the firm stand out from their competitors. This is both a detailed handbook for new engineers and a constant reference manual for seasoned professionals. It is likely that consulting engineering firms will present this guidebook to all of their engineers as a learning guide to influence their leadership and sharpen their management abilities. It is anticipated that companies which provide products or services to engineers will present this guidebook to engineers as a Premium-Gift to promote new business and to thank engineers for their past support. If purchased in substantial quantities, a Special Edition named in honor of the sponsor could be printed: (Sponsor's) CONSULTING ENGINEER'S "Guidebook." The book is divided into "three parts": Consulting Engineering; Your Image; and Engineering Management."
