• that the proponent should also inform all potentially affected residents of the nature of worksto be carried out, the expected noise levels and duration, and contact details; and• that for works above the highly affected noise criteria respite periods may be required, andfor works outside standard hours there needs to be a strong justification and negotiationwith the community (DECC 2009).Noise is likely to be created by construction trucks and machinery. These activities will be of ashort duration.Construction is expected to take six weeks and all work will be undertaken during standardworking hours. Given this, background noise monitoring and the establishment of noisemanagement levels for residential receivers is not proposed. The ICNG does, however,prescribe a highly noise affected criteria of 75 dBA L Aeq, 15min, which is the point at which theremay be strong community reaction to noise. Given the offset distance and the limitedconstruction activities proposed at the site, it is unlikely that dwellings, commercial premises orschools will experience a noise level above the highly affected level of 75 dBA L Aeq, 15min duringthe noisiest works.A range of standard construction noise mitigation measures is proposed to minimise noise (referTable 2), and the community will be provided with details of the works before constructionbegins.Construction VibrationVibration effects from the operation of heavy machinery, such as vibratory rollers or large earthmoving equipment have the potential to cause structural disturbance or discomfort. Theproposed work will not require the use of vibration-causing heavy machinery.Discomfort effects are not expected given the types of machinery required for constructionworks. Similarly, structural damage to buildings is not expected as the nearest buildings areadjacent to the railway and already experience vibration from trains on a regular basis.Operational Noise and VibrationNo operational impacts are expected.Possible Control MeasuresConstruction works will adopt Best Management Practice (BMP) and Best Available TechnologyEconomically Achievable (BATEA) practices as described in the Interim Construction NoiseGuideline (ICNG) (DECC 2009).In addition to the control measures listed in Table 2, the community will be notified of the works,duration and provided with contact details before work begins. Any noise complaints receivedwill be addressed by the Project Manager as soon as possible.Page 33 of 64
