Noise & Vibration case study

Wigan & Leigh College site remodelling s61

Background

Willmott Dixon Construction were appointed to remodel the existing Wigan & Leigh College site, off Parsons Walk, in Wigan. This involved the phased demolition of the existing college buildings, followed by the reconstruction of new college buildings and a car park.

The Construction Environment Management Plan (CEMP), produced to satisfy Wigan Council’s requirements, committed to preparing S61 (Control of Pollution Act 1974) Applications to seek prior consent in advance of the works and to demonstrate Willmott Dixon’s commitment to controlling and managing noise levels as a result of the works.

SRL were appointed to prepare these S61 Applications.

Challenge

This scheme posed several challenges with regard to potential environmental impacts. With multiple residences and schools in close proximity to the work site, controlling noise and vibration from the site, particularly during the demolition phases, was a significant concern.

Solution

SRL assisted the project by preparing S61 Applications in advance of each stage of the work, seeking prior consent from Wigan Council.

The Applications were informed by a baseline noise survey, undertaken to gather an understanding of the existing acoustic climate in the area, and therefore facilitate the determination of appropriate demolition/construction noise thresholds.

A commitment to employ Best Practicable Means was central to achieving the desired consents, including: proposals to take advantage of natural screening afforded by existing buildings (prior to demolition); to liaise closely with surrounding receptors regarding the works and durations; and to continually monitor noise and vibration levels during the works.
