NCHRP Web-Only Document 428: Quality Management for Digital Model–Based Project Development and Delivery, from TRB’s National Cooperative Highway Research Program, addresses two key challenges for state departments of transportation and other highway agencies: the use of 3D models as a new way to review construction designs and the review of the 3D models themselves.

The document is supplemental to NCHRP Research Report 1153: Digital Model–Based Project Development and Delivery: A Guide for Quality Management.
