Analysis of Construction Design Estimation Practices of Public Works Center, Great Lakes

摘要

The purpose of this study was to develop a statistically validated predictive model for construction design man-hours to aid in the decision-making process for assigning projects to PWC engineers and Architect-Engineer firms. This study was performed at PWC, Great Lakes and consisted of personnel interviews and the compilation of a database from internal reports. Although a predictive model was not developed, it was discovered that the design man-hours estimation procedure is inaccurate and causes PWC to hold customer funds that could be used for other purposes. A decision-making model was developed to assist in assigning projects to in-house design resources or to Architect-Engineer firms. In addition, significant cost savings are already being realized through the use of the Computer Aided Design and Drafting System, with greater savings projected when the system is fully installed.
