This document provides an overview of intelligent construction technologies. It discusses technologies that can collect, analyze, and use information to make decisions during construction. These include computer-aided construction modeling, high precision surveying using GPS and LIDAR, smart material production using automated monitoring and control, machine guidance using 3D models and GPS, quality monitoring through intelligent compaction and smoothness testing, and construction/data management with 3D/4D modeling and automated data linking between field and office. The benefits of these intelligent construction systems technologies include improved quality, reduced schedules, more effective inspections, and integrated construction and materials data.
