BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
11.16 Part 2 of BS 5228 gives guidance on methods for measuring vibration and how to assess its
effects on the environment and people. The main vibration impacts are likely to arise from piling
activities or heavy construction vehicle movements near sensitive receptors. Annex B gives
guidance on the significance of vibration effects in terms of human response to vibration (see
Table 11.1) and structural response to vibration (see Table 11.2).
Vibration
Level
Table 11.1 Guidance on Effects of Vibration Levels Perceptible to Humans
Effect
0.14 mm/s Vibration might be just perceptible in the most sensitive situations for most
vibration frequencies associated with construction. At lower frequencies, people
are less sensitive to vibration.
0.3 mm/s Vibration might be just perceptible in residential environments.
1.0 mm/s It is likely that vibration of this level in residential environments will cause
complaint, but can be tolerated if prior warning and explanation has been given to
residents.
10 mm/s Vibration is likely to be intolerable for any more than a very brief exposure to this
level.

11.17 Annex D of Part 2 of BS 5228 provides some historical measured vibration levels for various piling
methods and Annex E gives empirical formulae for the prediction of the resultant peak particle
velocity vibration levels for various types of piling. The formulae found in Annex E can be used to
estimate the vibration levels when detailed information about the piling method is known. If only
general information is known about the piling activities then a range of levels can be obtained from
the historical data presented in Annex D.
Operational Activities
11.18 The guidance documents used for assessing the potential impacts of fixed and mobile noise
sources within the development, once it is operational, are described below.
Horizontal Guidance Note IPPC H3 Part 2 Noise Assessment and Control, 2002
11.19 The Horizontal Guidance Note IPPC H3 Part 2 outlines the noise and vibration impact assessment
requirements for new and existing industrial sites. The aim of the guidance is to assist in
determining noise related BAT for a given installation.
