Many industrial, urban and transportation operations result in ground borne vibration. Ground borne vibration is often perceptible to humans, disrupting to nearby sensitive equipment and can even be damaging to adjacent buildings and structures. As such it is important to evaluate the impact of such activities on the surrounding environment, or, where there is to be new development near existing vibration sources, establish what vibration levels can be expected at the new site.
Ground vibrations can be produced a wide variety of activities, noise from:
Roads - Motorways - Highways - Railway - Quarrying - Construction - Blasting
Xi can assist your project by monitoring these vibrations and offering advice is resolving mitigating and meeting the relevant standards. Xi use a variety of measuring equipment including Syscom, Guralp, and Vibrock seismometers ensuring all relevant vibration data is captured.
Consideration to vibration should be made when any industrial or heavy activity is to happen in the vicinity of any sensitive site such as:
Optical Instruments - Observatory equipment - Magnetic Resonance Imaging (MRI) - Scanning electron microscopes - Medical facilities
Of particular importance is how people percieve these vibrations. Human response to vibration, Whole Body Vibration (WBV) and Vibration Dose Value (VDV) are of utmost importnace and are regulated by a range of standards.
BS 6472:2008 Human Response to vibration in buildings
BS 4142:1997 Method for rating industrial noise affecting mixed residential and industrial areas
BS ISO 4866:2010 / BS 7385 Evaluation and measurement of vibration in buildings
BS 5228-2 2009 Code of practice for noise and vibration control on construction and open sites
