5607.2.3 Monitoring plan and vibration limits.
FC § 5607.2.3
A monitoring plan shall be prepared and submitted for department review and approval setting forth the manner in which blast impacts (ground vibrations and air overpressure) upon buildings, structures, and infrastructure will be monitored. The monitoring plan shall be based upon the blasting plan and the pre-blasting survey, including the findings of the engineer who conducted the survey of structural conditions. The monitoring plan shall include the following information and documentation and such other information and documentation as the department may require: 1. The location and elevation of vertical control points on such buildings, structures and infrastructure, and shall set forth the type and location of any monitoring devices to be used, including tell-tales. The department may require monitoring of water shock when submarine (underwater) blasting is conducted.
2.Notification procedures to be undertaken if and when limits for ground vibration and/or air overpressure are exceeded, including notifications required by FC 5607.19.4.1.
3.Actions to be taken in response to limits for ground vibration and/or air overpressure being exceeded, including building inspection procedures, staffing, and use of the global strain method.
4.Preparation and submission to the Department of Buildings such documentation as that agency may require with respect to the continuing structural stability of affected buildings and any actions that may need to be taken to protect public safety.
