Geosystems

Major names in surveying equipment bid for attention in Hall A3 at Bauma: Pentax, Leica, Trimble, Topcon, Futura, Laser Alignment, Quante, Ammann Lasertechnik, BMI and Nestle were all just about in line of sight from each other.

Two of these got together in January this year when Leica Geosystems acquired Laser Alignment. Leica's expertise in land surveying fits well with Laser Alignment's tools for controlling construction equipment. And on Leica's stand was an impressively equipped quad bike designed to take the leg-work out of jobs such as surveying large scale siteslike airfields.

A high resolution global positioning system fitted on the quad gives a continuous read-out and record of x, y and z coordinates of the ground surface while a laptop mounted on the handlebars enables the surveyor to key in any required information from observations.

Output can be applied directly throughout the design and construction process. Traditional setting out involving pegs and profiles can be eliminated, says Leica, with its Gradestar GPS control system for dozers and graders. The operator simply follows instructions on a screen in the cab which has a highly visual display guiding the blade setting required to reach the necessary profile for each operation.
