3D laser scanning from DGT Survey Group captures thousands of above-ground existing conditions data points within minutes, cutting field time costs from days to hours. With this technology, there’s no need to interrupt or delay normal construction activity.
Reduce Change Orders
3D laser scanning data is accurate and comprehensive — reducing costly change orders due to designs based on inaccurate or incomplete existing conditions data.
Stay on Track
No more project-stopping, time-wasting delays due to existing condition disputes. Accurate, readily accessible 3D laser scanning data provides quick, decisive resolution to disputed existing conditions.
When maintaining any type of industrial plant, a big challenge is understanding the existing conditions of their site. For a chiller plant in Salem, DGT performed 3D laser scanning and modeling for documentation of its MEP assets. With this data, the plant can now safely perform upgrades, renovations and other plant development.
For the Bay Path Regional Vocational Technical High School in Charlton, DGT performed 3D interior surveys to aid planning and design of modernization. Our team delivered highly detailed and dimensionally accurate building existing condition models in Revit and AutoCad formats, depicting room shapes, as well as above-ceiling mechanical/ utility systems and structural obstructions.
The Tosteson Medical Education Center at the historic Longwood Avenue Quadrangle dates back to the original construction of the Harvard campus. Drawing from a 1949 survey from William S. Crocker Engineering, a DGT legacy company, we updated façade maps using 3D laser scanning to support the current and ongoing modernization of the building.
The McLauthlin Elevator Company Building in Boston’s North End is a historic cast- iron façade – one of the few remaining in Boston. For this 19th century architectural technology, DGT used 21st century 3D laser scanning survey technology to produce point cloud models that served as the basis for machine-controlled fabrication of replacement components in the on-going maintenance.
The Prudential Center is an iconic Boston landmark that has undergone much transformation through the years, with layers of infrastructure dating back to the beginning of the 1900s. It was one of the largest, single site developments in the early sixties and transformed an old rail yard in to a multi-faceted icon location in the heart of Boston. DGT legacy documents date back to almost the begin of this landmark project, and our unique services are still required on a regular basis. In preparation for expansion, DGT was contracted to perform construction support with advanced 3D modeling, delivered in Revit, for design of the new Boylston Street Arcade.
DGT performed 3D laser scanning services for two bridges being reconstructed in Providence, Rhode Island. The LiDAR data was used to document the existing conditions and design of the new bridges. DGT used terrestrial and mobile LiDAR with GPS control with the least amount of impact on traffic and safety of the crew.
