Activity Based Cotsting for Construction Companies provides guidelines on how overhead costs can be managed for using Activity Based Costing (ABC), providing gains in contractor competiveness. Illustrated with a range of case studies and examples it also presents a map that shows construction contractors how to implement ABC to calculate overhead costs accurately, identifying non or low-value added operations which can then be improved.

Yong-Woo Kim is Associate Professor of Construction Management in the Department of Construction Management at the University of Washington, Seattle, WA, USA. He teaches undergraduate and graduate courses in construction accounting, project delivery systems, lean construction and project cost analysis. His primary research interests are lean project delivery systems, sustainable construction and project cost management.
