Hodgson
& Hodgson Consultancy Division Resolves Noise Problems for Denne Construction
Hodgson
& Hodgson Group has provided acoustic consultancy to Denne Construction
on a new build project in Wandsworth - one of London's busiest boroughs.
The four-storey residential and commercial building is located on Garratt
Lane, in a bustling area for shopping and leisure.
The
Group's consultancy division was commissioned early in the project to
carry out an environmental noise assessment to evaluate the 'Noise Exposure
Category' of the building site and to determine whether the indoor ambient
noise levels would meet the criteria set by the Local Authority. Traffic
flow along the busy Garratt Lane causes high external noise levels, which
presented Hodgson & Hodgson with a considerable challenge: to provide
a building envelope specification which ensured that the required indoor
ambient noise levels were met.
Hodgson
& Hodgson's expertise in environmental and architectural acoustics
enabled its consultants to come up with an answer for the combination
of residential and commercial units. A mix of specialised double- and
triple-glazed units, along with acoustic through-wall and mechanical ventilators
with standard brick-block cavity external walls was recommended. This
solution ensured the appropriate noise criteria were met without any further
noise control measures being required. Pre-Completion Testing showed the
airborne and impact test results to be around 8dB better than the criteria
set out in Approved Document E (2003) for Purpose-Built Dwellings.
"This
was a challenging project," confirms Derek Butler, Senior Surveyor
at Denne Construction, "But Hodgson & Hodgson's consultants were
in constant communication with us and showed an excellent understanding
of the issues we were trying to resolve. This meant there was a smooth
flow of information at all times, allowing our timescales to be met."
