Ground Movement Monitoring Program
The safety of nearby buildings and structures is paramount, as in deep open cut installations.
The safety of nearby structures can be compromised if the structures are subject to greater
ground movements or vibration than they can withstand. For extremely challenging pipe bursting
operations (class C), a preconstruction survey and monitoring of the ground movement is advisable
if there are nearby structures. A preconstruction survey of all nearby buildings and structures
that documents all existing cracks, cosmetic problems, and structural deficiencies is recommended
prior to any work on site. The elevations of carefully planned settlement points (on nearby
buildings and on the ground surface) around the insertion and pulling shafts should be
surveyed prior to bursting, during bursting, and after bursting. These preconstruction
surveys and elevations monitoring can significantly reduce the risk of unmerited law
suits to the contractor and the owner.
