Construction Support

Donald J. Smith, Inc., offers construction support services to clients who utilize GPS Machine Control and Automated Machine Guidance (AMG) systems. Unlike most 3D cad service companies, we have over 20 years of experience building models for our survey department and know how to create accurate electronic 3D grade files from design plans. We can prepare 3D models for any type of project including highways, mass grading, commercial developments and residential subdivisions.

Accuracy and reliability of AMG systems have improved in recent years but require accurate site calibration and routine checks for good results. As professional surveyors, we can verify site control, set check points, assist with site calibration and perform surveys for quality control and assurance.

Some of our services include:

  • 3D Models for GPS and AMG Systems
  • Project Site Control (horizontal and vertical)
  • As-built surveys
  • Earthwork volume surveys and calculations
  • Monitor Machine control for quality control and assurance
  • Supplemental layout and staking (when survey grade is required)
