High Definition Surveying

Extensive construction and survey knowledge coupled with top quality equipment and software, allows us to produce, process, and deliver the highest quality project deliverables. Every scanning project is supported and constrained with a complete survey file. Leveraging best survey practices to quantify scanning data, ensures survey grade level of accuracy and precision for deliverables derived from the point cloud during post processing.

  • Bridges, Antennas and Towers

  • MEP Networks

  • Steel Sizing

  • Cloud Rendering


3D Surveying & Existing Conditions Model

Working with the industry’s most well-known design software, Sebago is able to create the solid 3D models you need to further improve your facilities or make your design.  From facilities and layout plans all the way to full record models we provide accuracy by utilizing our High Definition Surveying team to provide accurate and up to date information.  Using the cloud data, we are even able to accurately depict detailed facades to maintain model accuracy for historical projects. 

  • As-Built/Record Drawings

  • Architectural Details and Facades

  • Building Interior and Structures

  • Floor Plans and Layouts

Terrestrial Laser Scanning & Surveying

Utilizing laser scanning for larger terrestrial Surveys allows for an extensive acquisition of field data as compared to a more labor intensive traditional land survey. Using millions of data points to create an existing surface profile for a roadway or topo site allows the deliverable to reflect the exact conditions of the project site. Significant reductions of time on-site reducing overall field work and project cost. Data is quickly acquired in vast quantities and easily assembled with a smaller set of survey data.

  • Topography & Grading Plans

  • Streetscapes and Roadways

  • Volumes & Quantities

  • Existing Conditions



Whether it’s surveying a roadway, analyzing bridge components, documenting a historic building, quantifying material volumes or retrofitting an existing structure, High Definition 3D Laser Scanning is a highly efficient solution. Sebago Technics has been scanning since 2013 and has successfully completed a multitude of projects over a wide array of project disciplines. With a scan rate of 1,000,000 points per second, Sebago Technics can supply the highly-accurate and cost-effective dataset required to fully utilize today’s 3D design software. Once point cloud data is processed, surfaces and 3D objects can be created through Leica Cyclone, Cloudworx and Revit software. The resulting deliverable can be viewed in AutoCAD, Revit, MicroStation, Sketchup & Solidworks. We can even create 3 dimensional views and videos for use in presentations and marketing.

Founded in 1981, Sebago Technics is one of Maine’s leading land development consulting firms offering civil engineering, survey, landscape architecture, GIS, traffic/transportation engineering and environmental services. For more information please visit
