Specialist Noise Control Solutions Supports a Major Sewer Replacement Project

Case Study Overview

The Clancy Group were tasked by their client to carry out major sewer replacement works in the city centre of Edinburgh, near to Haymarket Station. The area features a number of hotels, guest houses, as well as residential properties immediately adjacent to, and over looking the site, as well as pedestrians walking past regularly.

The full scope of the project was to replace a 60m stretch of sewer pipes, working in 12m sections at a time. Equipment being used throughout the project was going to create significant noise pollution.

Challenge

The Clancy Group identified noise control was imperative to the job due to the excessive noise levels being created. Protecting the hearing of the workers, hotels guests, residents and pedestrians was imperative throughout the project.

Activities included hydraulic breaker and vacuum excavation. Hydraulic breakers are high performing mechanical devices used to demolish concrete. When in use they can create noise pollution reaching between 120-130dB. Following the use of the hydraulic breaker, a vacuum excavation was used to safely excavate around the underground utilities, this was going to create substantial noise, causing disruption.

Solution

RVT Group carried out a free site survey to truly understand the challenges Clancy Group were facing. Our experienced consultants were then able to provide a bespoke, effective noise control solution suitable for the project.

We installed equipment from our SOUNDEX® range including our Breaker Shroud for the hydraulic breaker activities, and SOUNDEX® Acoustic Quilts to reduce the noisy activities created from vacuum excavation.

The final solution RVT Group provided was the MONITEX® Environmental Noise Monitor. This unit measures a considerable sound in a range between 30dB to 120dB with a highly accurate response.

Following the implementation of RVT Group’s solutions, The Clancy Group successfully reduced the noise levels that workers, hotels guests, residents and pedestrians were exposed to.
