Vibration based condition monitoring is an invaluable way of assessing possible damage to existing buildings and infrastructure as a result of unwanted vibrations caused by programmed construction, demolition, blasting or other activities. Pre- and post-vibration surveys of properties adjacent to a client-controlled site can help property owners by detecting, documenting and monitoring pre-existing damage, where the condition monitoring and vibration analysis prior to large vibrations can identify conditions that may not previously have been apparent. Vibration condition monitoring and services therefore limits a contractor’s liability in their projects.
Vibration monitoring in construction can be instrumental in limiting liability for many types of clients undertaking a wide variety of projects involving a range of assets. Pipeline infrastructure, bridges, government buildings, hospitals, historic buildings and monuments and individual homes can all be monitored for potentially harmful vibrations.
Many public authorities require the vibration monitoring for certain types of construction, demolition or blasting projects. Vibration condition monitoring should begin prior to any substantial vibration-inducing activity so that a baseline of vibrations is recorded at the site. For instance, subway traffic may create a larger vibration signature than the construction’s pile-driving at the site in question.
Applus+ can also perform blast vibration monitoring for a single day at a construction site or over the longer term, for example during the demolition of a large building.
