I heard a story years ago about a surveyor who staked a "rectangular" lot with actual interior angles of 86å¡ and 94å¡.
The architect called for the new house to be parallel with the lot lines at the required setbacks.
The foundation was laid, the framing put up, the stucco and all its basics applied, the drywall affixed and so on.
Not until the kitchen cupboards were about to be installed was the error noticed!
Just think of all the money they saved by not having a surveyor stake the house too.
Got a set of column grid plans in digital and PDF from an architect. As I went through comparing the dimensions I found discrepancies, informed the construction managers who went to the architect. Architect then sent me a "more precise CAD" which consisted the precisions set to 1/256 instead of the 1/16 of the original. I was then able to round those errors up a little better...
The last set of house plans that I was ask to stake out had dimensions set to 1/64th.
The structure had two dozen offsets and when I input them into my data collector, it was several feet from closing.
Had to rotate it from the direction it was drawn because the Architect had warped the boundaries to fit his design.
I located the two boundaries it was close to and set two points to represent the two closest corners of the structure for them to work from.
Let the builder know what I had found and what I had marked and he was experienced enough to adjust as he went and got er done.
