1 INTRODUCTION

Vipac Engineers & Scientists Ltd (Vipac) was commissioned by Mirvac Pacific Pty Ltd to carry out a rail noise

impact assessment for Stage 7.3 of the proposed Gainsborough Greens residential development located on

Gainsborough Drive/Kosciuszko Circuit, Pimpama (Lot 3001 on SP291537). This rail noise assessment

includes the following:

Description of the development;

Discussion of the applicable noise criteria;

Prediction of rail noise levels for the lots in the proposed development;

Assessment of predicted rail noise levels against applicable noise criteria;

Discussion of noise mitigation if required; and

Recommendations and conclusion.

2 PROPOSED DEVELOPMENT AND SURROUNDING AREA

The proposed residential development is located on Gainsborough Drive/Kosciuszko Circuit, Pimpama in an

area zoned Medium Density Residential under the City of Gold Coast City Plan. The surrounding land uses

are as follows:

North – Existing detached residential dwellings

East – Vacant Land;

South – Existing detached residential dwellings

West – 1.8m acoustic barrier along the top half the site boundary, the Brisbane-Gold Coast Railway

line and the Old Pacific Highway.

The location of the proposed development is presented in Figure 2-1. Architectural drawings are presented in

Appendix A.

The proposed development comprises of 194 lots and the site layout is presented in Figure 2-2.

3 EXISTING NOISE ENVIRONMENT

Attended and unattended noise measurements were conducted at the development site between 19th

November 2018 and 22nd November 2018 using 4 environmental noise loggers and a sound level meter. The

noise loggers were used to record noise levels at 15 minute intervals with the microphone set up in free field at

1.5m above ground level. All monitors were calibrated before and after the measurements and no significant

drift was noted (<0.5 dB). A list of the equipment used is presented in Table 3-1.

The measurements were conducted in general accordance with Australian Standard AS 1055:1997 –

“Acoustics – Description and measurement of environmental noise”. Further information on the

instrumentation, measurement details, measurement results and weather data for the monitoring period are

presented in Appendix B. Weather conditions were fine during the noise monitoring, with some rainfall on the

last day upon the noise logger retrieval. This data has been excluded from our monitoring results.

The environmental noise loggers were installed near the site boundary to the west of the site as shown in

Figure 3-1.

Figure 3-1: Noise Monitoring Locations

The terrain of the development site is higher than that of the train line, and as a result, the trains were only

partially visible when passing through. The day time noise environmental noise during the site visit on 19 th

November was bird and insect noises, and the occasional train and traffic.

3.1 ATTENDED MEASUREMENTS

Attended measurements were conducted in close proximity to Location 3 for rail noise whilst on site on the

19th of November 2018. Two passenger trains passed by between 2:30pm and 2:45pm and the measurement

results were recorded. The attended and unattended measurements for that time period for the train passbys

are presented in Table 3-2.

As expected, the results from the attended and unattended results for that time period generally agree with

each other, with a difference of less than 2dB.

3.2 UNATTENDED MEASUREMENTS

The single event maximum (SEM) LAmax was calculated based on the arithmetic average of maximum levels of

the highest 15 events over the entire noise monitoring period for Location 3 and Location 4. The Location 1

and Location 2 noise data was not used due to the presence of the acoustic barrier. The LAeq,24hr was derived

from the entire noise monitoring period as well and the results are presented in Table 3-3 below.

residences in a transport corridor as it is located adjacent to the Gold Coast line to the west of the

development. Noise limits from the relevant sections of SDAP’s State Code 2 are presented in Table 4-1.

timetable. Table 5-2 presents the summary of the estimated daily train movements that passed by the site

during the week from 19th November 2018 and 22nd November 2018. Appendix D contains the QR timetable

with the train movement information used in this assessment.

5.2 NOISE MODEL CALIBRATION

The measured SEM LAmax noise levels at Location 3 and Location 4 as presented in Table 3-3 were used to

calibrate the noise model prior to modelling the rail noise impacts to the development. The model calibration

results are presented in Table 5-3.

5.3 PREDICTED NOISE LEVELS

5.3.1 PREDICTED OUTDOOR SPACE NOISE LEVELS WITH EXISTING ACOUSTIC BARRIER

The predicted noise levels for the outdoor space areas are tabulated in Appendix E. Noise modelling results

show the free-field rail noise levels for lots in the development range between LAeq,24hr 33 dB(A) and 48 dB(A).

For LAmax, free-field rail noise levels for lots in the development range between 51 dB(A) and 70 dB(A). Both

free-field LAeq,24hr and LAmax rail noise levels are predicted to comply with the SDAP private open space criteria.

Noise contour maps are presented in Appendix G.

5.3.2 PREDICTED FAÇADE-CORRECTED NOISE LEVELS WITH EXISTING ACOUSTIC BARRIER

The predicted external noise levels at the building façades are tabulated in Appendix E. Noise modelling

results show the façade-corrected LAeq,24hr noise levels range between 35 dB(A) and 50 dB(A). The façade

corrected LAmax noise levels range between 54 dB(A) and 73 dB(A). Both façade-corrected LAeq,24hr and LAmax

rail noise levels are predicted to comply with the SDAP external noise criteria at all building façades. Noise

contour maps are presented in Appendix G.

6 BUILDING CONSTRUCTION ACOUSTIC REQUIREMENTS

The predicted façade-corrected corrected noise levels and corresponding MP4.4 Rail Noise Categories are

tabulated in Appendix F. The rail noise categories range from 0 to 1 for the ground floor and 0 to 2 for the first

floor. The noise contour maps are presented in Appendix G.

Consequently, building construction should be designed to achieve the ratings specified in the MP4.4

document, as presented in Table 4-2. Glazing, external wall, ceiling/roof and ventilation requirements are

specified in Sections 6.1 to 6.4.

6.1 GLAZING REQUIREMENTS

Glazing requirements were determined to achieve acceptable indoor rail noise levels, as per MP4.4. Glazing

requirements are specified in Table 6-1.

It is required that the Rw performance ratings of the glazing systems (windows and frames) be certified by the

supplier prior to installation. Glazing and frame certificates will be required for building certification. Where

glazing system requirements are considered high, the design or glazed surface area can be reduced to

minimise the acoustic rating required.

6.2 EXTERNAL WALL REQUIREMENTS

The external wall construction options shown in Table 6-3 are example forms of construction to achieve

acceptable indoor rail noise levels. Alternative external wall constructions that achieve the specified acoustic

ratings may be adopted.

6.4 VENTILATION REQUIREMENTS

Acceptable indoor noise levels according to MP4.4 can be achieved: however, for the habitable rooms of

future residences on Lots where the MP4.4 rail noise categories are 1 or greater, doors and windows must be

closed. Alternative ventilation may include air-conditioning, borrowed ventilation, mechanical assisted

ventilation or other suitable methods.

7 CONCLUSION AND RECOMMENDATIONS

Vipac Engineers & Scientists Ltd (Vipac) has completed a rail noise impact assessment for Stage 7.3 of the

proposed Gainsborough Greens residential development located on Gainsborough Drive/Kosciuszko Circuit,

Pimpama (Lot 3001 on SP291537).

Rail noise levels have been predicted to comply with the State Development Assessment Noise Provisions

(SDAP) State Code 2 noise limits for all lots within the proposed development.

The rail noise QDC MP4.4 categories range from 0 to 1 for the ground floor and 0 to 2 for the first floor. As a

result, the building construction requirements to achieve compliance are as follows:

Selection of glazing as presented in Table 6-1;

Construction of external walls as presented in Table 6-3; and

Construction of ceilings and roofs as presented in Table 6-4.

For habitable rooms of future residences on Lots where the MP4.4 Rail Noise Category is 1 or greater, doors

and windows must be closed to achieve acceptable indoor noise levels. Under these conditions, alternative

ventilation will be required in affected rooms. Alternative ventilation may include air-conditioning, borrowed

ventilation, mechanically assisted ventilation or other suitable methods.
