Construction is going on close to the neighborhood. And I saw geologists and engineers working together as a team. I found out these Geologists work for Geo forward and one of their services includes methane inspection services. I didn't get this clearly so someone explained it better.
According to the little I grabbed, the inspection service involves checking the level of the methane around the construction site to prevent future explosion for the owner. I don't have a full understanding of this but you can check out the meaning here for clear comprehension.
