Advanced Technology

Our rail and tunnel specialists bring years of expertise and the most technologically advanced survey equipment available to the unique rail and tunnel environment. Since safety in this setting dictates the manner in which all work is performed, it is paramount to deploy personnel who are highly trained and accustomed to working within the potentially dangerous rail environment. Our rail survey professionals carry current e-RAILSAFE and Roadway Worker Training certifications and have years of experience working on some of the highest profile rail projects in the country.

Our level of expertise enables us to employ standard and creative solutions for capturing comprehensive track and corridor data. This includes implementing robotic instruments and the AMBERG GRP trolley to meet precise transit authority specifications; mobile LiDAR systems to quickly and accurately collect miles of rail corridor data; GPS/GIS equipment for asset location mapping services and conventional instruments for topographic, rail alignment and right-of-way surveys.
