When a sensitive building is to be constructed near a source of vibration such as overground / underground railway or construction sites, the groundborne transmission of vibration must be considered. There are standards such as BS8233 which provide vibration guidelines for residential, educational and commercial buildings. In some cases, this is invoked in local authority planning policy.
By conducting vibration surveys using accelerometers and analysing data using noise prediction methods it is possible to determine the necessary level of vibration isolation required. This data is needed to ensure that noise level on sites built close to sources of vibration meet the required standards. Solutions are often found using resilient constructions such as isolated buildings, sprung concrete slabs or resilient wall/ceiling linings.
If necessary, we carry out an auralisation at our 3D studio in Brixton to allow clients to subjectively appreciate the incoming noise from vibration. That allows a confirmation of the brief before a sign off on large design elements such as structure isolation of a whole building.
