2 months into the site strip out works, the originally instructed acoustic consultants had advised that it would not be possible to provide acceptable acoustic conditions for residential use which left the client severely exposed.
The site was affected by ground borne noise and vibration levels due to underground train movements along the Jubilee Line between Green Park and Bond Street stations. The options available for treating the building were severely restricted by the Listed/Conservation Area status of the building. Furthermore, the site lay directly above one of the tunnels and so there were major concerns about the potential for excessive additional loading associated with any works being transferred to the tunnels themselves. The high value nature of the proposed properties also meant that it was essential to maximise floor space.
Using a range of techniques, we managed to lower the train noise by over 15dB and achieve full compliance with the client’s stringent requirements.
RBA Acoustics were thrilled to have been awarded the ANC Award 2016 for Vibration for our originality in approach to the challenge.
