Gransberg, Richard C. Ryan (both: construction science, U. of Oklahoma) and Texas-based engineer Calin M. Poescu offer a guide to project managers and other construction, architecture, and engineering professionals who need to estimate the cost of equipment on a given project and do not have the necessary data at their fingertips because their routine business does not involved a lot of equipment-related construction. They especially appeal to public agency equipment managers, whose need is to minimize equipment costs rather than maximize the profit earned by the equipment.
