We have a project where GC will be doing all site work like for new equipment pad and POCO xfmr. so it will require quite a bit of trenchihg for primary and secondary service along with equipment to be installed. We would normally do this work ourselves or sub out. GC wants us onsite to help with site work survey and layout. They want us to tell them where to dig for pole lights, poco xfmrs, service equipment, etc. I know most of you guys wouldnt do proects like this but what concerns do you see in projects like this where now we are the GC seems like if we have to tell concrete guys how to layout site work?
