Meeting new standards

Staying in the top position as a Swiss contractor means a constant focus on quality and the bottom line as standards around these advance: more precise planning; less wasted resources; tighter volumes based on better accuracy, and faster, more frequent surveys empower all this and are a baseline requirement today.

Keeping an innovative edge

For both existing small and large-scale surveys and future projects, Wingtra provides the efficient, cost-effective solution that can tackle complex terrain, enabling surveys in tight weather windows and delivering consistent, reliable accuracy. This improves project flow for more competitive operations.

Seeking a drone survey solution that would take their operations across small, medium and large projects to the next level, WALO tested WingtraRAY and the SURVEY61 payload on an earthworks site for the Sportwelt Gossau complex—a center that will host a variety of sport activities in St. Gallen, Switzerland.
WALO captures surveys over the 50 acre site every month to plan earthworks based on high-accuracy volumetrics and topographical analysis. The site features tight weather windows with fog, so an efficient platform that can quickly get the data is essential.

Challenge and solution headlines

U Challenge

Weather can't be scheduled

Flight windows between storms, fog banks, tides can be fleeting and cause a day or more delay with slower systems. 

m Solution

Fast capture matters

No matter the size of the project, faster is better. WALO witnessed WingtraRAY  prove this during intermittent fog on testing days.

U Challenge

Mixed results

Lower quality optics, less automated planning and different pilot approaches can mean data quality variance across surveys.

m Solution

Dependable quality

High-quality optics, easy-to-repeat exact logistics across pilots and proven reliability ensure data quality stability over time.
U Challenge

Costly planning errors

Infrequent survey information introduces uncertainty into decision-making and plans based on guessing vs. real measurements.
m Solution

Better margins

High-quality optics, easy-to-repeat exact logistics across pilots and proven reliability ensure data quality stability over time.
