Noise and vibration trigger values	PW17	1 Noise and vibration trigger values 1.1 This requirement sets out the noise and vibration trigger values for the provision of off-site noise mitigation under the Non-statutory off-site mitigation and compensation policy (Application document number— APP210.01). References in this document to trigger values are to be construed as references to the trigger values in this requirement. 2 Residential property (airborne noise) 2.1 Subject to paragraphs 2.2 and 2.3 the airborne noise trigger values for noise insulation and temporary rehousing for residential property are as set out in Table 1. All construction noise levels will be predicted or measured at a distance of 1m from any affected eligible façade, which must have windows to bedrooms or living habitable rooms. In this requirement “habitable room” has the same meaning as in the Building Regulations 2000 Approved Document F (2010 edition). 2.2 The trigger values shown in Table 1 do not apply where the ambient noise level is greater than the noise insulation trigger value. In such cases, where the ambient noise level (in the absence of construction noise) exceeds the relevant noise insulation trigger value shown above, then— 2.2.1 the ambient noise level shall be used as the construction noise level required to trigger insulation; and 2.2.2 the ambient noise level +10dB shall be used as the temporary rehousing trigger value. 2.3 The trigger values shown in Table 1 apply if— 2.3.1 the predicted or measured noise level exceeds the noise trigger value for noise insulation or temporary rehousing at the property for at least ten days out of any period of 15 consecutive days; or 2.3.2 the predicted or measured noise level exceeds the noise trigger value for noise insulation or temporary rehousing at the property for 40 days in any six-month period; or 2.3.3 where a significant effect is identified using the assessment methodology defined in the Environmental Statement and forecast noise level exceeds assessment category C defined in the Environmental Statement even if the duration trigger values in paragraphs 2.3.1 and 2.3.2 are not exceeded; and (a) noise insulation does not already exist that is of an equivalent standard to that which would be allowed for under the Noise Insulation (Railways and other Guided Systems) Regulations 1996 (the ‘1996 Regulations’); or (b) grants for noise insulation works in accordance with the Land Compensation Act 1973 have not already been paid. 3 Residential property (ground borne noise and vibration) 3.1 The following ground borne noise and vibration trigger values apply for off-site mitigation— 3.1.1 ground borne noise measured near, but not at, the centre of any room in a property— 45 dB LASmax. 3.1.2 ground borne vibration measured at the centre of any floor in a property— (a) daytime (7am to 11pm)— a vibration dose value (VDVb) of 0.8m/s1.75; and (b) night-time (11pm to 7am)— a vibration dose value (VDVb) of 0.4m/s1.75. 3.2 Temporary respite accommodation will be triggered if the predicted or measured vibration exceeds the trigger levels in the property for more than one day. 3.3 At any residential property where noise insulation cannot reasonably be installed the trigger value for temporary rehousing shall be the same as the trigger value for noise insulation as set out in Table 1. 4 Special cases— Residential 4.1 Night shift worker— the night-time trigger values in paragraphs 4.2.1 and 4.2.2 shall apply during the day and evening. 4.2 Vulnerable persons (as defined in the Non-statutory off-site mitigation and compensation policy (application document number— APP210.01))— 4.2.1 for airborne and ground borne noise the trigger levels at 2 and 3.1.1 minus 10 dB shall apply; 4.2.2 for ground borne vibration the trigger values at paragraph 3.1.2 divided by 2 shall apply. 5 Special cases - houseboats 5.1 Development shall not commence at Putney Embankment Foreshore, Kirtling Street, Heathwall Pumping Station or Chambers Wharf until trigger values for noise insulation and temporary rehousing in relation to noise and vibration impacts on houseboats in the vicinity of those work sites have been submitted to and approved by the relevant planning authority. 5.2 Trigger values for temporary rehousing where noise insulation in relation to houseboats cannot reasonably be installed shall be the same as the trigger values for noise insulation agreed under paragraph 5.1. 5.3 Thereafter the approved values shall be applied as the trigger values for houseboats as a special case. 6 Special cases— community facilities 6.1 Airborne noise trigger levels are set 5 dB above the prevailing ambient noise level (indoors or outdoors) or the guidelines / limits set in the following whichever is the higher— (a) BS8233 (1999) Sound Insulation and Noise Reduction for Buildings. Code of Practice. British Standards Institution; (b) Education Funding Agency (2012). Acoustics Performance Standards for the Priority Schools Building Programme. Department for Education. The Stationery Office Limited; (c) Department for Health (2011). Acoustics— Technical Design Manual 4032—0.3. The Stationery Office Limited; and (d) British Council for Offices (2009). Guide to Specification.
Notice of maintenance works	PW18	The undertaker shall give notice to the relevant planning authority not less than 28 days in advance of carrying out ten yearly maintenance operations for any works at any of the sites in the area of the relevant planning authority. Such notice will provide a description of the works to be undertaken, the location and extent of the works, estimated duration and means of access to the site and necessary arrangements for maintenance/provision of associated services to be provided to the sites.
Baseline monitoring	PW19	Development at any work site shall not commence until ambient noise monitoring has been carried out at sensitive receptors in the vicinity of that work site and the following conditions have been met- (a) locations for ambient baseline noise monitoring have been submitted to and approved by the relevant planning authority. (b) a method statement for noise monitoring, to include the duration of monitoring, has been submitted to and approved by the relevant planning authority. (c) noise monitoring has been carried out at the approved locations in accordance with the approved method statement. (d) the results of the noise monitoring have been submitted to the relevant planning authority.
