Introduction 5 1.2 Synthesis Objective This synthesis seeks to gather state-of-practice information regarding the current processes and strategies for effective use and transfer of DTMs from design into the construction phase of highway projects. DTMs have significant potential to improve the accuracy and efficiency of construction and inspection operations, yet little research exists to detail practices and performance.
