1 project-2 coordinate systems
I??m about to start a new construction staking project that we did not do the original design survey??
I??ve only been out and calibrated to the control at this time, but after doing so, it seems to be on our city system (essentially state plane) not moved to ground or anything. That being said, the site is relatively large so I do see a little difference between my grid and ground distances (about 0.2?? across the site). For most of the project, it??s negligible and I??ll roll with the calibration as is for all the civil work, however, there is a large building with a lot of structural steel and a pool inside that will require certification. I??m thinking of setting some additional points to create a scale factor only system for just the building layout after a majority of the site work is done since I have some tolerances that are pretty tight on the building and pool.
anyone had experiences like this with projects?
