Whether your firm is driving piles to provide support for the installation of bridges or other structures, or blasting to remove a bedrock outcrop for a roadway, you must be concerned about the effects of vibration on nearby buildings and other structures. Before your project starts, you need to know the potential for damage so you can plan your work in a manner that will avoid causing damages. During and after the project, it is imperative to have data concerning vibration levels in case of litigation by property owners or occupants. Pre-blast surveys and vibration monitoring provides this information for you.
