Granite’s never used a drone on the type of project like this to come up with quantities, so wanted to see the cost-benefit and time benefit of utilizing the PPK versus using ground control points.
Say it takes four flights for me to fly the entire site at 400, it’s going to take me eight flights to fly it at 200, so it’s only worth doing when we really need that increased accuracy.
Without that, it would have been really tough because we were always chasing this impacted soil, and as we chased it, we had to take more over dirt, and we had to prove that to the owners that we’re taking out this much over dirt, and show this impacted material that’s on T&M’s is not included.
For job progress, it’s an easy way to show owners and upper management where we’re at and what’s going on on the site.
