Now there's an opportunity for a startup. Make the process paperless. Go out with drones, phone apps, and ground-penetrating radar, tie all the info to location. Hook this up to AR goggles, so the people involved can see all the data when on-site. Much of the environmental paperwork could be generated automatically.
Drone-based ground penetrating radar is now available.[1] It's a lot cheaper than finding pipes and cables during construction.
