Long time lurker first post. No license just a 25 year button pusher who has been with same company the entire time. I've learned many things from this forum and honestly some of the technical GPS discussions get way over my head. I've read so many different takes on this I figured it was time to ask and see what people a lot smarter than me say. For example we are the consulting engineers for a new sewage treatment plant. The entire job site is probably only 600' X 300'. What I typically do on any new job is use Trimble VRS to establish SPC on the point I will set base up on. After initial VRS everything is done base Rover. On this job and every construction job the contractor will set 4 points boxing the job site in and then we will use base Rover and shoot contractors points for Horizontal then run levels for vertical. We give these coords to contractor and they localize to these 4 points. So on small job sites what is the proper way to do things. Use one point every time like I do or localize to 4 points.

The one in the middle really only does you any good if it's more than 1500' between your perimeter control.
