The Way It was Done for Last 20 years, is No Longer Good Enough! Is your project SHOVEL-READY?

3-D Models are the Future of Surveying in Major Construction - WHY?

  • Horizontal & Vertical Alignments are Created Simultaneously - Visual Impacts are Now Apparent
  • 3-D Models Provide Virtual Rendition of a Project
  • 3-D Model Allows Clearance Checks from All Directions
  • Eliminates Stakes as Obstacles
  • More Accurate & Higher Quality Results

Accurate 3-D models (DTM/TIN) created from your CADD (2-D/3-D) or paper plans.


Our tools provide the quality assurance to identify areas of concern, such as drainage, design conflicts, etc.


Final surface file prepared in most Automated Machine Guidance interfaces.

Why have a Professional Surveyor Prepare Your Model?

  • Surveyors Interpolate Between 2-D Paper Plans and the 3-D Construction World
  • Surveyors Provide Quality Control of 3-D Virtual Engineering Data
  • Surveyors Interpret the Design to Fit on the Ground
Welcome to the New World of Construction Surveying
  • Contractor's Demand More Accurate Terrain Data
  • Contractor's Need for Creation or Refinement of 3-D Models for Construction Purposes
  • Contractor's Need for Accessible Project Control
  • Contractor's Need for Verification of Tying 3-D Model to Project Control and Ground Features
