Corridor Mapping

Every surveying project is unique and corridors mapping even more so. These are long, linear projects that run adjacent to public and private properties and right-of-way, have encroachments, and are often active infrastructure with specific safety concerns and MPT. This requires surveyors to use the latest technology and apply best practices for data collection and mapping.

Routes take many forms in our modern infrastructure and GdB has experience with them all:

  • Article VII Permitting
  • Roadways
  • Railways
  • Bike Paths
  • Pipelines
  • Transmission Lines

Funding for infrastructure renewals and the renewable energy transition in full swing make route mapping ever more important. Discover why GdB is the Trusted Advisor on these projects.
