Shock and vibration impact from construction sites, manufacturing facilities and traffic can compromise the condition of buildings, be a hazard for workers well-being and productivity, and affect a residential neighbourhood. In an industrial context, excessive vibrations can also induce stress for the bearings and seals of expensive plant and therefore reduce the life of the equipment, cause fatigue and premature failure, or be an indicator of an upcoming problem.
We measure, monitor and asses vibration levels according to Standards and Guidelines. To obtain a deeper understanding, operational vibration measurements like pressure and noise may also be conducted on machinery and the affected areas, complemented by investigations of natural frequencies during outages.
Once the root-cause of a problem is identified (structural or acoustic resonance, imbalance, misalignment, poor design of isolation etc.), we develop targeted measures tailored to your company’s needs to minimise hazard potential, ensure legislative requirements are met, reduce downtime, and improve productivity and reliability.
Vibration, and the equipment that causes it, can be considered a hazard and therefore covered by OHS and the model WHS legislation. There are also general Regulations, Compliance Codes and Codes of Practice, which must be adhered to in various States and Territories.
In order to obtain a permit or approval you may require a Vibration Assessment (can also be known as a Noise and Vibration Study, a Noise Impact Statement or an Acoustic Assessment Report) and an Environmental Noise Assessment. We work with planners, developers, builders, property managers and owners to help them determine exactly what their regulatory requirements are.
If you’re about to plan and develop a new industrial plant, commercial facility, office building or a high rise residential apartment block, it makes financial sense to assess the potential sources of vibration and noise and address them early on.
Excessive vibrations and noise are often two sides of the same problem, as vibrating surfaces always emit airborne noise. To understand the sound path from source to receiver, different variables have to be taken into account. Structural vibration (structure-borne noise) and airborne noise as well as pulsations in gas and fluid (medium noise) are the most important measurements to get the full image of a noise and vibration problem. SafeWork Australia reports that there is evidence that workers who are exposed to vibration and noise at the same time are more likely to suffer hearing loss than workers exposed to the same level of noise alone.
