Piling Vibration
Monitoring
Some piling methods, such as drilled auger, do not generate
significant vibration and are the method of choice for vibration
sensitive construction sites. The nature of the ground
in some areas, or the purpose of the piles, can mean that some
piling jobs have to be undertaken with impact or vibration driven
piling techniques as commonly used for sheet piling, and
this can give rise to ground vibration transmission.
Examples include where coffer walls are created to line temporary
pits or to form the retaining wall for residential developments
boarding canals, rivers, lakes and even sea defences. The
necessary operation of piling equipment close to houses carries
the risk of complaint from residents and, in some cases, damage
to properties.
Often carried out at the same time as noise evaluations, monitoring
of ground or building vibration produced by piling operations
can be required at the commencement of the site preparation
work on a construction site. Surveys
might be carried out during the first two hours of the first day
of piling. Results have to be written up quickly and often
delivered to the local planning authority later in the day to demonstrate
that the piling work is not causing damage.
Other projects include:
- Channel tunnel rail link for Morgan Vinci
- Hunstanton sea wall for Aarsleff Piling
- Blackpool promenade redevelopment for Birse Civils
- St Denys rail protection scheme, for Commercial and Marine Piling
- Brentford

Blackpool
Promenade Enlargement |
Blackpool, the UK resort, is upgrading
its sea defences and extending its famous Promenade as part
of major improvements to keep visitors and tourists coming
to the town. Spectrum was called in to monitor the
impact of vibration and noise from sheet piling. Part
of the piling is very close to the South Pier, and monitoring
was carried out to ensure vibration did not damage this famous
landmark.
