Synthesis of Information Related to Highway Practices. Topic 52-01. State of Practice on Infrastructure Inspections for the Digital Age

Construction inspection is critical in any transportation project because it ensures conformance with plans, specifications, and material requirements, in addition to environmental, safety, and traffic control standards. Historically, departments of transportation (DOTs) have employed on-site workforces to execute infrastructure inspection using traditional inspection methods. Currently, better and more cost-effective technologies can potentially satisfy the need for efficient inspection and monitoring of critical infrastructure systems such as water delivery systems, wastewater mains, dams, levees, bridges, and roadways. With the latest technological advancements, the construction inspection landscape has been rapidly changing through incorporation of digital sensors, intelligent machines, mobile devices, and new software applications. The technology innovation program (TIP) at the National Institute of Standards and Technology (NIST) has identified advanced sensing technologies and advanced repair materials for infrastructure (e.g., water systems, dams, levees, bridges, roads and highways) as a critical national need area of civil infrastructure. Unmanned Aircraft Systems (UAS) technology has been used to inspect local infrastructure, monitor ongoing projects, and conduct environmental analysis. The objective of this synthesis is to document the various technologies used by DOTs to inspect infrastructure projects. Information to be gathered includes (but is not limited to): (1) The technologies used for infrastructure inspection; and (2) The different methods used to assess the viability, efficiencies, and return on investment (ROI) of such inspection technologies. Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
