A noise survey of the former sewage treatment works recorded ambient and background noise levels at the site and in proximity to the nearest residential properties. An assessment was reported on the potential noise impact on amenity and the likely effect on environmental noise levels in the surrounding area from the operation of the screening and crusher equipment.

Noise predictions from published and actual sound power levels of the main plant were calculated.

Recommendations for mitigating sound from site operations were produced including the design of earth bunds for controlling noise generated by fixed and mobile plant and machinery.

A nighttime noise survey was carried out to assess sound leakage from the basement of the building when recorded amplified music was being played.

A number of sound transmission paths, weaknesses in the external structure together with poorly fitted and non-acoustic fire doors were identified.

A scheme of building works was recommended and implemented.

In addition, a noise limiter was subsequently installed and a noise limit was set and agreed with the Licensing Authority.

The Licensing Authority were satisfied that its requirements were met.

Noise surveys on a weekday recorded noise emissions from car servicing and repairs and associated activity.

The survey on a Saturday morning obtained ambient and background noise levels in the absence of car servicing. Assessments were carried out in accordance with BS4142 and these showed that there would not be a significant likelihood of complaint arising from continued use of Intec House weekdays and from Saturday morning working.

A scheme of mitigation to reduce peak noise levels outside potential noise sensitive properties recommended that a noise barrier be positioned along the boundary to control noise emissions from the basement car park and vehicular movements on the frontage of the site.

Noise surveys were carried out around the peripheries of the site affected by road traffic and various industrial uses.

Full noise assessments were undertaken in relation to road traffic and industrial uses, a number of which have 24hrs working.

The assessments produced design guidance for the future development of up to 700 new dwellings.

The sites noise exposure to road traffic and industrial sources indicated that the existing residential development fall into noise exposure category B/C.

The form of construction of the new dwellings to the current Building Regulations part E incorporating mitigation measures would ensure that a good standard of internal amenity can be achieved. 

Planning consent was granted within 13 weeks.

The object of the site survey was to ensure that the developer has a baseline noise level of the site's exposure to road traffic noise. This was required prior to carrying out section 278 works which could be used as evidence in the event local residents seek to claim compensation for increased noise levels due to these highways works.

A noise survey was carried out with respect to the proposed redevelopment. The level of noise to which the site is exposed was assessed. A noise model of the site was created and calibrated to reflect the noise levels measured on site and this has been used to determine the noise levels incident upon all of the building facades.

The calculated incident noise levels were subsequently used to calculate the required facade acoustic performance to meet the internal noise criteria set out in BS8233 as advised as being suitable criteria by the Local Planning Authority.

The specific acoustic performance requirements for both glazing and ventilation in all facades of the building were calculated and reported to discharge conditions in the planning consent.
