dc.description.abstractMilitary construction, like the private industry, needs improved methods by which: (1) quality can be assured throughout the construction process, (2) the degree of construction progress can be assessed and documented, and (3) the performance of systems and materials can be assessed over time to aid in maintenance decision-making. Although these aspects of construction processes have traditionally been addressed through an empirical approach, recent advances in computer technology have provided new opportunities for improving upon the traditional methods. The U.S. Army Construction Engineering Research Laboratory (USA-CERL) is exploring the use of a sequential construction analyzer (SCA) to improve quality assurance, allow for more effective tracking of construction progress, and provide data for making decisions about maintenance. The SCA is a computer-based system that uses images obtained via various types of cameras to enhance the image data into useful information. This study was conducted to identify potential applications of the SCA in three areas of construction: buildings, construction sites, and paving. Many possibilities exist for applying this technology to the construction industry. The SCA concept is being optimized at USA-CERL, and a prototype is under development. When the prototype has been field-tested successfully, it will be used to develop specific applications for the Army and private industry.-
