LAND SURVEYING AND MAPPING PROJECTS

AMTRAK NORTHEAST CORRIDOR

Laser Scanning and Mapping

‚Äč

3-D laser scanning to produce base mapping for sections of the Northeast Corridor trackside wi-fi network.  Scanning enabled surveyors to set up away from the tracks and also pick up crucial design elements such as height and sag of catenary wires, location and height of catenary and signal supports and other ancillary equipment not easily surveyed by traditional methods.  The use of scanning technology also minimized time required on the right-of-way thus saving significantly on the deployment of Amtrak safety crews.  Approximately 50 sites have been surveyed to date.  Client: Maverick Construction

MASSDOT I-495 ANDOVER BRIDGES

Laser Scanning and Mapping

Andover - Lawrence, Massachusetts

3-D scanning was employed to determine pavement and bridge elevations for approximately one mile of I-495 and ramps. Scanning was performed from off the roadway, thus enhancing safety and avoiding the cost of lane and shoulder closures.  A 3-D model and base plan was prepared and merged with traditional survey data as the basis for the design of six bridge replacements by Chappell Engineering.  Client: MassDOT
