I don't understand the requirement to be within 0.001'.?ÿ Results with those tolerances are virtually impossible to repeat in the field and nothing will be built coming even close to those specs.?ÿ
I was seeing specs being sent out for max tolerance of 1/4". The buildings got built, but if someone forced me to bet, I bet there's a 95% chance they didn't meet that spec.
@mightymoe construction error versus survey error is not what this thread is about.?ÿThe client requested elevation data within the building accurate yo 0.01 ft.
Nothing to do with a building getting built and whether its construction by the contractor adhered to data provided by survey.?ÿ
Actually the specs I'm referring to required that the surveyor sign off on each main element of the building that they were within 1/4". So yeah, it's about survey error and construction "error". The project got held up for years for some reason, but the building is there now, almost no chance that the spec was met. So yes this is about the thread.?ÿ
