(a) Any works which do not cause noise emissions to be more than 5dBA higher than theRating Background Level (RBL) (background) noise levels at any nearby residentialproperty and/ or other noise sensitive receivers;(b) the delivery of plant, equipment and materials which is required outside these hours asrequested by police or other authorities for safety reasons and with five (5) daynotification to the community;(c) emergency work to avoid the loss of lives, property and/or to prevent environmental harm;All works outside those mentioned above must gain written approval from the Proponent andhave notified the community at least five days in advance, prior to commencing the works.4.4.2 High Noise Generating ActivitiesRock breaking or hammering, jack hammering, pile driving, vibratory rolling, cutting orpavement, concrete or steel and any other activity which results in impulse or tonal noisegeneration shall only be scheduled between the following hours unless there is no impact onresidential properties and/ or other noise sensitive receivers:(a) 8am to 12pm Monday to Saturday; and(b) 2pm to 5pm Monday to Friday.4.4.3 Construction Noise and VibrationA Construction noise and vibration management plan (CNVMP) must be included in theCEMP for the Project. The CNVMP must identify sensitive receivers and appropriate noisecriteria and provide details of specific noise and vibration control and management measuresthat will be implemented during construction. The CNVMP must address any noise mitigationmeasures identified in the Environmental Assessment and be implemented for the duration ofconstruction. The CNVMP will be made publically available upon request.4.4.4 Construction Airborne NoiseThe Proponent must implement all reasonable and feasible noise mitigation measures withthe aim of achieving the construction noise management levels as described in the InterimConstruction Noise Guidelines (DECCW, 2009).4.4.5 Construction VibrationVibration resulting from construction and received at any structure outside of the Project mustbe limited to:(a) For structural damage vibration - German Standard DIN 4150:Part 3 – 1999 “StructuralVibration in Buildings: Effects on Structures”; and(b) For human exposure to vibration the acceptable vibration values set out in theEnvironmental Noise Management Assessing Vibration: A Technical Guideline (DEC2006).These limits apply unless otherwise approved through the CEMP.Subject to landowner agreement, building condition surveys shall be completed on thefollowing buildings/structures prior to proximate piling, excavation or bulk fill or any vibratoryimpact works including jack hammering and compaction (“Designated Works”):a) all buildings/structures immediately adjacent and surrounding roads of the DesignatedWorks.Page 26
