Construction inspection is one of the key tasks performed by the Construction Bureau staff of the Alabama Department of Transportation to verify that construction conforms to the project specifications established by the Department. Inspectors must provide proactive inspection to avoid nonconformance issues. The inspection of drilled shaft construction is both challenging and critical since an improperly performing drilled shaft can cause significant damage to the superstructure and become a serious hazard to driving motorists. The focus of this project was the development of a computer-based tool, a resource system, to provide significant resource material on drilled shaft construction inspection. The resource system includes text, visuals and electronic versions of the forms used to document construction. The system can be easily installed on a laptop and accessed on the web, and will be available on a CD/DVD disk. The project provided an important technology transfer tool for construction inspectors in city, county and state agencies charged with the responsibility of verifying that the construction of drilled shafts is in conformity with the specifications established by their respective agencies.
