Vibration Assessment

BS 5228-2 & BS 6472-1 construction and operational vibration screening

Source and Propagation

Vibration Source *

Distance to Receiver (metres) * Distance in metres from source to nearest sensitive receptor

Soil Type * Affects vibration attenuation and amplification

Existing Background PPV (mm/s) Optional, default 0.3 mm/s

Receiver Sensitivity

Receiver Type * BS 6472-1 receiver categories

Vibration Duration *

Building Type * BS 5228-2 building damage thresholds

Mitigation Measures

Select all applicable mitigation measures to reduce predicted vibration levels

Vibration isolation at source Isolation pads, springs, or mounts (40% reduction)

Alternative low-vibration method Replace with quieter technique (50% reduction)

Ground-borne vibration barrier/trench Cut-off trench or barrier walls (30% reduction)

Restricted working hours No work during sensitive periods (management measure)

Real-time vibration monitoring On-site monitoring with alert thresholds (management measure)

Phased construction programme Reduce source intensity per phase (15% reduction)

Pre-condition building survey Document baseline condition before works (management measure)

Resident communication plan Advance notice and liaison officer (management measure)

Recommended Planning Conditions

Note: This assessment is a screening tool based on BS 5228-2:2009 and BS 6472-1:2008. Detailed baseline vibration surveys and post-completion monitoring may be required. Conditions should be tailored to site-specific constraints and refined during detailed design phase.
