Pre-Construction Surveys
A pre-construction survey serves to document pre-existing cracks that could become the subject of concern or a claim after construction begins. The survey serves as a baseline for monitoring any potential construction impacts on the structure and to identify potential structural conditions that might make the structure more sensitive to vibration effects.

Vibration & Sound Monitoring
Ground vibrations and air overpressures from blasting and other heavy construction sources are the cause for concern on many projects that take place in congested areas. These effects must be monitored and controlled to mitigate the risk of causing impacts to adjacent structures and equipment. Vibration and sound monitoring can be invaluable in addressing neighbor concerns from perceptible vibrations that are well within established safe structural standards. Read more
