Warrawee Substation Page 1Operational Noise & Construction Noise & Vibration AssessmentReport No. 11332 Version B1 INTRODUCTIONRail Corporation NSW is proposing to build a new Traction Substation adjacent to the existingrail corridor along Brentwood Avenue, Warrawee. This report provides an operational noiseassessment and a construction noise and vibration assessment. It is understood the completedsubstation would be similar to the West Ryde Substation at the corner of Reserve Road andWest Parade, Denistone.This report deals with operational noise and then construction noise and vibration includingtraffic noise along Brentwood Avenue during construction.
Warrawee Substation Page 2Operational Noise & Construction Noise & Vibration AssessmentReport No. 11332 Version B2 SITE DESCRIPTIONThe proposed location for the new traction substation is along the rail corridor at BrentwoodAvenue. Figure 2-1 provides an illustration of the proposed site location.Figure 2-1Proposed Site Location for Warrawee Traction SubstationAttendedMonitoringLocationsProposedSubstationLocationNoise LoggerLocation2.1 Site DescriptionThe western extent of the substation will be 7m setback from the rail line with the footings atsimilar RL to Brentwood Avenue Most of the equipment (including rectifiers, switches,switchboards, reactors, DCCB etc) related to the substation would be housed in a 1.5 storeybuilding with louvres for air flow. The top of the building would be higher than the rail line. Theventilation fans would be located on the western façade of the building. The ventilation fansused will be the ‘IVR Turbo Ventilator’ which we understand uses a ‘Typhonic’ ball bearingsystem which enables the ventilator to operate with minimal noise emissions. The externalequipment includes two main transformers along with the auxiliary transformer which would belocated in bunded / walled yards on the north and south end of the building. A small domestictype air conditioner is provided. A solid brick wall at a height of 3.2m will be constructed alongthe eastern façade of the bunded yards extending around the southern façade by 2.5m andextending around the northern façade by 1.5m providing shielding to the nearest residences inBrentwood Avenue. The brick wall barrier will be positioned at a 1m setback and will stand0.5m higher than the transformers.
