Paragraph 21 Construction noiseI1

For normal daytime construction and demolition works carried out on weekdays between 07:30 and 19:00 and on Saturdays between 08:00 and 13:00, the noise level measured at a noise sensitive receptor (as defined in Table 9.24 and Figure B1 of Chapter 9 of the environmental statement (Document 5.2)) must not exceed L_{eq, 12hour} 65 dB(A) wherever practicable. Where this is not practicable prior approval under section 61 (prior consent for work on construction sites) of the Control of Pollution Act 1974^f1 must be obtained.

An assessment of construction and demolition noise must be undertaken in accordance with British Standard 5228:2009 – “Code of Practice for Noise and vibration control on construction and open sites” (Part 1 – Noise) at a noise sensitive receptor. Noise levels must be measured weekly during the stages of construction including ground works, piling and road and rail construction stages unless complaints are received in which case the procedures in requirement 23 (monitoring of complaints) must be followed.

Subject to health and safety requirements, broadband reversing alarms must be employed on mobile plant.
