The objective of this study is to develop a guide for construction inspectors that (1) describes what information construction inspectors need to utilize data from 3D models and how to best document construction activities, and (2) identifies and catalogs the business needs and core competencies of construction inspectors using data from 3D digital models. At a minimum, the research shall include consideration of the following questions: What inspection activities potentially require data originating from a 3D model? What constraints prevent inspectors’ use of 3D models or digital information? What data is needed for inspection compliance and what is a suitable format for inspectors’ use? How do state DOTs ensure the correct data is being extracted and how will this data be provided to the inspector? What 3D data are needed for inspectors to accurately document and verify field changes or design changes? What are the mechanisms for inspection staff to use data from 3D models to improve construction inspection processes? Accomplishment of the project objective will require at least the following tasks.
