Preserving Benchmarks during Repaving

Most counties I believe have a standard spec or procedure on how the Contractor should preserve, protect, or replace a survey monument in case it is disturbed or damaged during repaving procedures. Typical street monuments are embedded into the ground 3+' so it will be difficult to disturb the actual location of the pin. What about mag nails or "y" cuts on the roadway surface. We are repaving a roadway and some of the bench marks are in the form of mag nails and "y" cuts that are going to be disturbed. Not sure why an actual street monument was not installed for these areas. Thanks for your help!

RE: Preserving Benchmarks during Repaving

If the monuments are disturbed or destroyed they will need to reset by a licensed land surveyor. If you know they are going to be destroyed, be certain to hire the surveyor prior to construction, so he can accurately locate original monuments location.
