About the Author
Dan Atcheson (1945-2020) learned construction at the side of his father, a Texas architect. Dan started working construction projects as a teen: framing, plumbing, electrical, every trade from earthwork to roofing. After a rewarding career on job sites, he joined the engineering faculty at Texas Tech University to teach construction estimating. Later he toured the country, conducting seminars for construction estimators. Dan is the author of seven estimating manuals and dozens of articles published in construction trade magazines. His references have been adopted for use in state-sanctioned construction trade and licensing programs.
