Using 3D Digital Design Data in Highway Construction--A Case Study

completed

Select a representative highway project to showcase the successful utilization of three-dimensional (3D) digital design data and use the information gathered from that project to develop broader guidance that can be used by highway agencies. Through a comprehensive case study, a representative highway construction project that successfully transitioned digital data from design to construction, the objectives in the Key Project Objectives field will be accomplished. Goals: Fully document the process and policies that enabled the successful utilization of three-dimensional (3D) digital design data in construction. Develop generalized guidelines based on this case study that also includes information on known design model formats and/or extensible markup language (XML) schemas for highway agencies to properly generate accurate 3D models for downstream uses in construction and other phases of project delivery. Document differences and similarities of each design formats and/or XML and the associated design model challenges. With each model, address the areas of real-time verification, conduct quality assurance/quality check (QA/QC), and manage data. Document and make recommendations for further development and deployment of the design model standards as the technology moves forward. Document the types of costs and resources required by industry and agencies for implementation of these technologies.
