Keys to a successful project
When vibration control is important to the success of a project, a qualified vibration engineer should be engaged to assist in the development and implementation of an effective mitigation strategy. The first step is to assess the performance of the structure. It is recommended to perform a measurement survey when possible, as data from the site is helpful to understanding the dynamic properties of the system and can be used to develop a computer model of the floor. Using this information, various control methods can be evaluated to determine the best option for the project. The vibration engineer can assist the team with implementing the solution in the project design documents and specifications, quality control (QC) testing, installation, and commissioning.
Conclusion
Successful management of floor vibrations in building reuse scenarios requires an understanding of existing vibration conditions, vibration criteria targets, and feasibility of mitigation options. A qualified vibration engineer can assist the team with assessment and development of solutions. As the results from such an assessment can have substantial impact on project costs and timelines, the floor vibration control strategy should be developed as early as possible for the project. Problematic vibrations are costly and difficult to fix once a facility is fit-out and occupied.
