Solid Waste Authority Debris Volume Survey

The Solid Waste Authority (SWA) engaged WGI to compute the volume of numerous debris stockpiles at the SWA facility. Using unmanned aerial systems (UAS) technologies, WGI accomplished this task for a total volume of 9,584 cubic yards in a 3-hour flight time. This includes the establishment of on-ground control to collect and process the stockpile volumes accurately. Several of the piles were manually cross-sectioned to vet the UAS data accuracy. The difference between the manual cross-sections and UAS data collection was 1%. Conventional survey methods would have taken approximately two days of field and office processing. The UAS data collection and processing took 7 hours, providing the SWA with the benefit of time and cost savings for the project.
