Control Surveys

Horizontal and vertical control are developed to create a framework around which other surveys can be adjusted. These control surveys are used for accurate mapping projects in the construction of underground utility systems, roadways, power lines, tunnels, and many other high precision projects. These surveys tie a project into defined coordinate systems and elevation datums. TEC Land Surveying utilizes GPS and high accuracy total stations to perform precise control surveys. Our technicians use meticulous field procedures and our survey technicians thoroughly analyze and adjust field data to produce highly accurate control surveys and reports.
