St Marylebone Bridge Special School

We were appointed to provide detailed design advice for BB93 and BREEAM. We were also appointed to provide Section 61 (S61) advice and Noise Vibration and Dust monitoring for the scheme.

The scheme is within a constrained residential area and our client was required to submit a Section 61 agreement to the council prior to commencement of works. We assisted Galliford Try in this work with a Noise and Vibration assessment following the guidance of British Standard 5228 Parts 1 and 2 (BS 5228:2009-1, BS 5228:2009-2, British Standard 7385 (BS 7385), British Standard 6472 (BS 6472).

The timescales for this work were tight and to speed the process up we actively engaged with the council to ensure their requirements were met, agreed changes of standard conditions where appropriate and agreed BPM where necessary.

We also agreed monitoring locations in advance reducing the original number of positions from four NVD (Noise, Vibration and Dust)on all boundaries of the site, to 1 NVD well placed and suited location. This resulted in a considerable saving on monitoring costs to our client along with ensuring all residences were well protected from NVD with a well managed and agreed monitoring strategy.

Further work included determining transfer functions to allow a considerable uplift from the monitor positions to the dwellings, and still meet the onerous Westminster vibration requirements.

The project is progressing well on site and due for completion in 2022.
