WALO Bertschinger AG maps 16 ha monthly with Wingtra for 1 cm accuracy

WALO Bertschinger AG, a major Swiss construction contractor, sought a drone survey solution to improve the efficiency and accuracy of its earthworks and progress tracking across projects of all sizes. Their challenge involved operating within tight weather windows and needing highly repeatable, reliable data to avoid costly planning errors and protect profit margins.

The vendor, Wingtra, implemented its WingtraRAY drone and SURVEY61 payload. This solution enabled fast data capture in intermittent fog, delivering consistent high accuracy with an absolute accuracy of 1 cm. As a result, WALO gained a dependable system for monthly surveys, which contributes to better planning, reduced field hours, and an overall return on investment.
