5607.22.1 Demolition blasting.
FC § 5607.22.1
Whenever demolition blasting is conducted, such professional engineer shall, upon the completion of the blasting operations at the job site, conduct a structural survey of all of the buildings, structures and infrastructure previously surveyed and submit to the department a report documenting the elevations of the vertical control points and the absence of any observable changes in the pre-existing condition of such buildings, structures and infrastructure, or identifying any changes and the conclusions to be drawn therefrom. Elevations of the control points shall again be measured by such professional engineer at intervals of 1 and 6 months after the completion of the demolition work, and a report containing this data, and conclusions to be drawn therefrom, shall be promptly submitted to the department as an addendum to the original post-blasting survey.
