Introduction 5 A survey was created to capture the state of practice of delivering 3D digital models to contractors within DOTs. Under the guidance of the topic panel, the survey was divided into the following categories: demographic information for respondents, demographic information for 3D digital models, agencies not using 3D digital models in construction, agencies using 3D digital models for information purposes only, and agencies using 3D digital models for information purposes and as contract documents.
