Noise generated by construction activities can be significant and, for
large projects, may last for lengthy periods. This can therefore lead
to considerable impacts on adjacent residential properties or other noise
sensitive developments. The impacts may be greater still if the works
must be carried out during ‘out of hours’ during the evening
or night-time, when people are generally more sensitive to noise.
Construction noise calculations can be undertaken using our powerful in-house
acoustic software modeling capabilities. This allows possible mitigation
options to be assessed prior to commencement on-site and the effects of
using different plant/techniques or reprogramming to be assessed.
We have an extensive database of noise levels for various types of plant
and activities, based on measurements that we have undertaken during numerous
site visits. We are familiar with construction techniques and can advise
on alternative plant and techniques that may be used to control noise,
to reduce the environmental implications of a noisy work environment.
In the United Kingdom, construction noise is governed by the Control of
Pollution Act (CoPA) (1974). Section 60 of CoPA allows Local Authorities
to take action where they consider that noise from construction is, or
is likely to, constitute a statutory nuisance. Section 61 of CoPA allows
a person to apply for "Prior Consent for Works on Construction Sites"
and that person must demonstrate he will operate Best Practicable Means
(BPM). Once a Local Authority has given Consent to the works under Section
61, it cannot then serve a notice under Section 60. Follow the link for
comprehensive guidance on CoPA.
Building Acoustics Planning Software
Our software undertakes the calculation of airborne and impact sound transmission
in buildings and of airborne sound transmission of outdoor sound. The
calculation of sound transmission is worked out by the software which
takes into account all sound transmitting elements and systems into consideration
which are relevant for the individual room-to-room situation. In addition
to the separating and the four flanking elements, doors and windows can
be inserted into the separating construction. Further, flanking elements
or even airborne sound transmitting systems, such as ventilation and cable
ducts, can be added.
All calculation results for airborne sound transmission between rooms
and from the outside can be rendered audible with for various interior
and exterior sound sources and for different kinds of receiving rooms.
We are experienced in the production and submittal of applications for
the "Prior Consent for Works on Construction Sites" under Section
61 of the Control of Pollution Act and can provide guidance on the steps
which must be taken to ensure that Best Practicable Means (BPM) is being
Noise and/or vibration monitoring is often required for construction activities,
for example to demonstrate compliance with noise or vibration limits.
We can provide a broad range of monitoring solutions, which can be tailored
to meet the requirements of clients and the local authority. These may
include long-term unattended noise and vibration monitoring and attended
