Noise and Vibration Impact Assessment – Crompton Way, Bolton

20.02.16

Acoustic Consultancy for Planning

REC supported a planning application for a proposed residential development in Bolton which included for the construction of 281 residential dwellings and 3 commercial units for B8 use (distribution and storage). Having been commissioned by Bellway Homes, REC provided a Noise and Vibration Impact Assessment in support of the development. The site was located close to existing commercial units including the Warburtons factory and a railway line.

Given the locality of the site to a large industrial and commercial area and a busy railway line, REC was presented with the significant challenge of calculating the impact of several different sources upon the proposed development.

Noise Impact Assessment

The Noise Impact Assessment identified that the key noise sources impacting upon the development Site were rail traffic using the Bromley Cross to Bolton Railway Line to the east, industrial noise from the Warburton’s Factory to the south and Oliver Kay to the south east and noise from emergency sirens associated with the Police Station to the north of the Site.

As a result, the only issues to arise were that of noise levels inside the proposed dwellings when windows were open. Alternative ventilation was recommended to the Client in order to meet the local planning authorities’ stringent noise criteria and REC undertook extensive consultation with the environmental health department to agree acceptable conditions for the developer whilst protecting amenity levels.
The Noise Impact Assessment also set Mechanical and Electrical Plant Noise Emission Limits for any proposed plant items which may form part of the commercial element of the development in the future.

Vibration Impact Assessment

The Vibration Impact Assessment identified that the key source of vibration impacting upon the development Site was from rail traffic and appropriate consideration was given towards any potential mitigation measures required to ensure a commensurate level of protection against noise and vibration for future residents.
