Quality Management for 3D Model-Based Project Development and Delivery

The three-dimensional (3D) model-based approach for project development and delivery (herein called “3D Model”) is close to market saturation for highway roads and continues to gain market penetration for highway bridges. State departments of transportation (DOTs) have begun changing the medium of construction contract documents from paper or two-dimensional (2D) plans to 3D Model that is contractually binding. The drivers of this major change are the ability for contractors and inspectors to consume 3D Model directly to support project activities and communicate the design intent. However, changing the medium of construction contract documents has created challenges to the state DOTs, including a lack of robust review and documentation procedures, and automated quality control (QC) and quality assurance (QA) management processes for 3D Model. The procedures for review of 2D plans are well established but do not translate easily to 3D Model. There is a need to provide guidance to aid state DOTs with the review of 3D Model, including data validation as well as QC and QA, and provide opportunities to automate the review and documentation procedures. The objective of this research is to provide a guidebook to assist state DOTs with developing quality management processes for 3D model-based approach for project development and delivery.
