Analysis of Design Changes on Navy Construction Projects.

摘要

The purpose of this research was to investigate design related changes on Navy construction contracts. With the results of this study, it is hoped that the Navy can improve on certain areas of design reviews in order to minimize the number and cost of design changes on future construction projects. This research included the study of design related contract modifications on 23 construction projects located in the Southeastern part of the United States. Southern Division, Naval Facilities Engineering Command, provided copies of the construction contract changes that were related to design which included an error or omission in the design and unforeseen conditions relating to design. These changes were then categorized by the engineering discipline responsible for design and then quantified by number and cost for each category. They were further categorized by the type of design deficiency, i.e. incorrect dimensions or sizes, incorrect details, interferences, omissions and revisions. The analysis then focused on how to improve design reviews by both the Architectural/Engineering (A/E) firm and Southern Division. Ideally, if the A/E conducted appropriate in-house reviews, additional reviews by the Southern Division should practically eliminate design changes that occur during construction.
