I've seen those well spaced dig holes at another construction site. I am NOT saying this for sure about this site. The one I am familiar with was to determine the possibility the site maybe on top an ancient Indian burial ground. There was a requirement for how far the holes where to be separated in a grid pattern and how deep each hole had to be. The soil then had to be sifted through a specific size screen. Nice video.
