Pre-construction Surveys can be a very powerful tool to limit risk and liability when performed prior to construction activities.
By recording pre-existing conditions, contractors have a record of adjacent structures in the event that claims are made for damages caused by construction activities. Post-construction surveys are a helpful visual confirmation to have if damage is alleged. The Pre and Post surveys can be compared side by side to confirm if claimed damages have occurred. Typically representative high-definition photos are taken along with a detailed narrated high definition video. The pre-construction survey is typically complemented with the installation of optical crack gages on existing cracks and further complemented with vibration monitoring during construction.
