These standards provide frequency‐dependent vibrationlimits related to cosmetic damage, noting that cosmetic damage is very minor in nature, is readilyrepairable and does not affect the structural integrity of the building. The recommended vibration limitsfrom BS7385 for transient vibration for minimal risk of cosmetic damage to residential and industrialbuildings is shown in 6‐14.Table 6‐14 Transient Vibration Guide Values for Minimal Risk of Cosmetic Damage (BS7385)LineType of Building1 Reinforced or framed structuresIndustrial and heavy commercialbuildings2 Unreinforced or light framed structuresResidential or light commercial typebuildingsPeak component particle velocity in frequencyrange of predominant pulse4 Hz to 15 Hz 15 Hz and above50 mm/s at 4 Hz andabove15 mm/s at 4 Hzincreasing to 20 mm/s at15 Hz20 mm/s at 15 Hzincreasing to 50 mm/s at40 Hz and above6.4.3 Potential impacts – construction noise and vibrationThe LAeq(15minute) NMLs at the identified representative receiver locations were determined on thebasis of unattended background noise monitoring undertaken for the project and in accordance with theNSW EPA’s ICNG. The NMLs which are relevant to the proposed works are detailed in Table 6.5.Ref No: 2260812 42
