39 Summary of Findings The primary objective of this synthesis study was to document current processes and strategies for the effective use and transfer of DTMs from design into the construction phase of highway projects. Secondary objectives were to identify DOTs that have experience using DTMs in construction and to provide an overview of implementation to date and lessons learned that identify success factors and challenges.

Summary of Findings 41 In the case examples, the DOTs noted the time savings and accuracies achieved for quantity measurement as meaningful benefits, along with the ability to support their contractors' use of AMG. • DOTs were more strongly aligned with their vision of long-term benefits from DTM use.

42 Practices for Construction-Ready Digital Terrain Models The findings from this synthesis project demonstrate some inconsistencies in the use of DTMs in construction. DOTs have a wide range of experience in both the number of projects and the years of experience with DTMs.
