TOTAL STATION

Total station technology captures points of interest in 3D space. A total station is a computer that measures the movements of a telescope and the timed reflection of a laser beam to provide dimensional data. As the telescope is rotated to focus on the points to be measured, the computer measures and records the horizontal and vertical angle of rotation. A laser beam is then projected to the point providing a distance measurement. The computer then calculates the point’s position in three-dimensional space.

When measuring geometric shapes such as piping, flanges, beams, columns, vessels, and supports, the entire element can be measured, located in three-dimensional space, and modeled in CAD by capturing a few selected points with the total station.

Strengths:

  • Highest precision +/- one millimeter

  • Superior range (1200 ft.)

  • Eliminates the need for field trim and rework

  • Provides comprehensive dimensional control for detail design, fabrication checks, trial fitting in model space and construction field support

Limitations:

  • The learning curve associated with data capture, data processing and modeling is steep

  • Points are captured one at the time making the field work more time consuming
