101 The objective of this synthesis is to provide state DOTs with information about specific emerging technologies that are in varying stages of implementation for highway construc- tion. Specifically, the synthesis will (1) identify and document technologies currently in use by DOTs to deliver construction projects, (2) document benefits and drawbacks of using emerg- ing technologies, (3) identify opportunities to improve construction delivery, (4) identify barriers that DOTs have experienced in applying specific technologies to construction deliv- ery, and (5) document lessons learned in the application of specific emerging technologies and their use by DOTs for highway construction. The synthesis will focus on the following technologies: ⢠Visualization and modeling technologies for constructability, communication, and docu- mentation during construction; ⢠Interconnected technologies for construction vehicles, equipment, and tools at construction project sites; ⢠Safety technologies used during construction for DOT and contractor workers and the traveling public; ⢠Instrumentation and sensors during construction to evaluate short-term or locked-in boundary conditions (e.g., the support conditions of structural elements) or member forces in specialty projects; ⢠Uses of unmanned aircraft systems (UAS) for construction monitoring, documentation, survey and inventory; and ⢠Any other promising technologies currently in use by DOTs.
