The use of GPS survey equipment allows for rapid and accurate surveys during establishment of controls and project execution.  We upload the data collected from robotic total stations directly into the computer, and quickly develop alternative design solutions during feasibility studies and preliminary engineering phases. EDA has embraced the use of CADD software for road design that allows us to refine the design, estimate quantities, and finalize the plan sheets in a relatively short period of time. ​

Adapting to Changes in Technology
Roadway Design
