This thesis identifies the causes and costs of changes to military construction contracts and discusses how excessive project cost growth can be reduced by thorough constructibility, using service and technical design reviews. 25 military construction projects, administered by the Corps of Engineers, were identified for study. Project files were reviewed to determine the reasons for and costs of 778 items of change contained in 268 modifications. Project cost growth was correlated by reviews conducted, project size, project type, and design agency. The study found the major causes of mods to be design deficiencies, user requested changes, and unknown site conditions. Most design deficiencies were found to occur in architectural aspects of design, followed by the mechanical, then electrical design disciplines. The study further found that projects receiving technical, constructibility, and using service reviews had significantly lower overall cost growth than projects not receiving all three reviews. However, the lack of any one review could lead to cost growth increases regardless of the detail in which the remaining reviews were conducted.
