Carlson Construction is an integrated cut/fill takeoff and 3D surface modeling software solution designed for site and road construction. It offers powerful inspection and 3D viewing tools for elevating 2D designs to 3D model files.  Carlson Construction includes powerful tools for designing and modeling different aspects of road design, from new construction to road widening and repaving.

Key Abilities:

  • Cut/Fill Estimating
  • Output 3D Machine Control Files (Carlson Grade, Trimble, CAT-Accugrade, Leica, and Topcon)
  • Output Construction Staking files for Site, Roadway, and Building Columns and Offsets



Carlson GeoTech provides the ability to import borehole data for analyzing subsurface conditions and materials.

“GeoTech will model all core samples and produce a detailed, easy-to-read report  for drill logs, cross sections, and plan view,” says Dave Carlson, V.P. of Development for Carlson Software.

In addition, this information is fully integrated with Carlson Civil, for determining site stability and suitability, and also Carlson Construction, for accurate strata takeoff estimation.

Carlson GeoTech supports AutoCAD® and comes with IntelliCAD® built-in. This is in addition to working on legacy AutoCAD versions.
