Amendment made in response to Noise Conclave report and evidence of Matthew Stead Notes 1 The noise affected level represents the point above which there may be some community reaction to noise. 2 The highly noise affected level represents the point above which there may be strong community reaction to noise. Amendment made in response to Noise Conclave report and evidence of Elkin NVP5 Blasting trials and assessment Construction Where blasting is proposed, a series of initial trials at reduced scale must be conducted prior to production blasting to determine site-specific blast response characteristics and to define allowable blast sizes to meet air blast overpressure and ground vibration limits. If blasting is required, an assessment of the potential noise and vibration impacts, and a strategy to minimise and manage those impacts must be prepared, including preparation of an appropriate community information program. Manage construction vibration NVP6 Construction vibration targets (amenity) Construction and regenerated noise Implement management actions if the following guideline target levels for continuous impacts to protect amenity vibration from construction activity to protect human comfort of occupied buildings (including heritage buildings) are not achieved (levels are calculated from the British Standard BS6472-1:2008). Notes 1 The Guideline Targets are non-mandatory; they are goals that should be sought to be achieved through the application of practicable mitigation measures. If exceeded then management actions would be required 2 The VDVs may be converted to PPVs within a noise and vibration construction management plan. NVP7 Construction vibration targets (structures) Construction vibration targets for structures are summarised in the tables below. Guideline values for the vibration velocity to be used when evaluating the effects of short term vibration on structures.
