Towill’s surveyors and photogrammetrists have worked on numerous rail projects, providing design and construction support including primary survey control, topographic mapping, utility investigations, right of way engineering for land appraisal and acquisition, earthquake safety and seismic retrofits, track and tunnel alignment verifications, and construction management for rail corridor and stations. We have surveyed and mapped many high-profile metro rail projects throughout the United States.
