NCHRP Synthesis 20-05 Topic 54-04: Mobile Devices as a Tool for Digitalized Project Documentation and Inspection

ABSTRACT NCHRP Synthesis 20-05 Topic 54-04: Mobile Devices as a Tool for Digitalized Project Documentation and Inspection Consumer-grade mobile devices, including smartphones, tablets, peripheral devices, and Rovers, are increasingly used as innovative tools in construction project delivery, documentation, and inspection. Advancements in camera technology combined with increased accuracy in geolocation, graphical displays, and LiDAR abilities provide a very powerful engineering/construction technology that is also widely accessible and used by most construction professionals on jobsites. A sample of mobile device applications that can be utilitized by construction professionals include: digitalized documents; geolocation of data; augmented reality with engineering precession; capturing 3D images of as-built conditions through built-in LiDAR cameras; object recognition through AI; viewing of 3-D models; access to inspection history; connecting QA results to the model; data storage, object recognition, and feature extraction methods; and, improved communications. The objective of this synthesis is to document state DOT practices for using mobile devices to support digitized project documentation and inspection.
