Figure 4.1 — Site location

The development site is bordered by mixed use/residential, commercial and industrial use buildings ranging between 4 and 5 storeys to the North, East and West of the site. Immediately to the south of the site across Stewart Street is the rail corridor servicing south and east suburbs. Richmond Station located approximately 50 meters to the west of the development site.

The rail corridor services Metro Electric Multiple Units (EMUS), V/Line locomotives and V/Line Diesel Multiple Units (DMUs). Freight trains also operate along the corridor. As the V/Line and freight trains operate only on the south-bound lines furthest from the development, greater peak noise levels are likely to originate from EMUS operating along the east-bound lines.

5 NOISE MEASUREMENTS

A noise logger was deployed at the development site for 24 hours over the 12th and 13th of April 2017 to assess the existing acoustic environment and perform background noise measurements in accordance with SEPP N-1 and SEPP-N2 during Day (0700 — 1800), Evening (1800 — 2200), and Night (2200 — 0700) periods. Weather conditions at the site during measurements were dry with light winds. A calibration check of the noise logger was performed before and after the measurement set, no significant drift was noted. As the rail corridor is raised approximately 3 meters above ground level, and roof access was not available, the logger was deployed in an open window of the second floor of the existing building with direct line of site to train lines and Richmond Station. The microphone was positioned in the centre of the window opening, flush with the window face. The room behind was of sufficient size to minimise reflected noise. The location of the logger is shown in Figure 5.1.

Figure 5.1 — Noise logger location

Noise levels were recorded in 1 second increments to capture train horn and wheel squeal events. Measured noise levels are given in Table 5.1. Background noise levels for evaluation of SEPP N-1 and N-2 noise limits were selected from the lowest LA90,30min values present within the Day, Evening and Night periods. Given the number of train movements, only the highest measured train event within each period is presented along with the highest LAeq,30mins value from each period. Values in bold font indicate the relevant metric from each measurement.

Onsite observations found that noise associated with the nearby commercial tenancy (east) was of significantly lower level than the rail corridor noise, and no noise from the industrial tenancy (north) was observed.

The noise levels L90 are used for the calculations of noise limits for EPA policies SEPP N-1, and Leq and Lmax levels are used for the design of facade glazing constructions. Instrumentation used for the noise measurements is presented in Appendix B.

Noise associated with the adjacent rail corridor and Richmond Station was consistently the dominant source. Observed noise sources associated with the rail corridor and Richmond Station included train horns, wheel squeal, pass-by noise, and amplified announcements from Richmond Station. Of these, train horns produced the greatest peak noise levels, wheel squeal the greatest sustained noise levels and station announcements were audible but lower than other sources. For glazing design, train pass-by events, wheel squeal and horn soundings were each considered in order to achieve the required interior noise amenity levels.

6 GROUND VIBRATION MEASUREMENTS

Measurements of ground vibration were performed on the 12th of April 2017 to capture the vibration levels present during rail pass-by events. Measurements were taken on the footpath immediately in front of the

development site, approximately 15 meters from the nearest track. A total of 15 train pass-by events were

recorded including several from EMUs operating from Platform 9 (close to development). The highest ground

vibration event recorded was used to predict internal structure-borne noise levels resulting from rail activity and evaluate human comfort due to whole-body vibration exposure.

Assuming no attenuation between measured ground vibration levels and those present on the penthouse level

of the development, the recorded ground vibration levels are predicted to produce 40dB(A) in bedrooms and

42dB(A) in living rooms. The measured ground vibration is also compared to human comfort criteria from AS 2670.2-1990. Results are shown in Figure 6.1.

Figure 6.1— Highest measured vibration acceleration 1/3 octave band spectrum compared to A2670.2 criteria.

For buildings of the planned development's size, a vibration transmission reduction of 5dB — 15dB can

reasonably be expected for values measured on the ground immediately outside of the building to those

measured inside the base of the building. Additionally, vibration is generally expected to be attenuated by

approximately 3dB from one floor to the next. Given the measured levels, ground vibration from railway activity is considered unlikely to disturb occupants within the development.

Ground vibration from V/Line and freight units is not considered to present greater risk than measured levels from EMUs as these units only operate along the southern link corridor (see Figure 4.1). Attenuation due to distance separation is considered sufficient to limit the ground vibration levels.

7 ACOUSTIC DESIGN CRITERIA

7.1 RECOMMENDED INTERIOR NOISE LEVELS

Australia and New Zealand standard AS/NZS 2107 recommends design criteria for conditions affecting the acoustic environment within occupied spaces. Design sound pressure levels (SPL) for residential, commercial, office and retail buildings are given in Table 7.1. The selected Design levels for this project are indicated in bold font. These are applicable to steady state or quasi-steady state sounds and are the reference criteria for selection and assessment of building components that exclude noise both external to the building (e.g. traffic noise, industrial noise), and within the building (e.g. building services noise). This standard is not intended for either the assessment or prescription of acceptable noise levels from transient or variable noise levels such as aircraft noise, construction noise, railway noise, crowd noise and emergency vehicle audible warning devices.

7.2 RAILWAY NOISE

The Australian & New Zealand standard AS/NZS 2107 is not intended for assessment of acceptable noise levels from variable noise sources such as railway noise. While there is no specific legislation of guidance for existing railway noise in Victoria, maximum acceptable internal noise levels for railway noise intrusion within residential occupancies can be referred to from VCAT decisions and the NSW EPA guidelines. As no particular limits are provided for non-residential uses, the criteria for living rooms is adopted for general office areas, open plan offices, and small retail stores. The maximum acceptable noise levels for railway noise intrusion adopted for in this report are summarised in Table 7.2.

7.4 NOISE EMISSION FROM THE DEVELOPMENT

7.4.1 PLANT NOISE AT RESIDENTIAL PROPERTIES

Mechanical plant noise associated with the development must be controlled at any affected residential properties in accordance with State Environmental Noise Policy SEPP N-1. According to the SEPP N-1 policy the environmental noise limits are determined based on a two part procedure — determination of the existing background noise levels (percentile sound pressure level LAN) and zoning levels (obtained from the town planning scheme map). The general background noise levels for Day, Evening and Night periods were measured at the site as shown in Figure 5.1 and the town planning scheme map is shown in. Table 7.3 presents the calculated SEPP N-1 limits. The background level for each period was taken from the lowest 490,30m in values present within each period.

Table 7.3 — SEPP N-1 limits for the development and surrounding residences (dB(A)]

Sunday & public holidays

0700hrs — 2200hrs

Night Monday — Sunday 2200hrs — 0700hrs 47 38 47

At this stage of the project, no details for mechanical plant servicing the development are available. Given the significant proportion of commercial tenancies planned for the development, and associated ventilation requirements for these tenancies, it is recommended that further acoustic assessment be performed at later stages of the project to ensure SEPP N-1 limits are not exceeded.

7.4.2 PLANT NOISE WITHIN ANY AFFECTED COMMERCIAL PROPERTIES

The noise emissions from plant into the nearby commercial buildings need to be assessed according to the requirements of the acoustic environment inside the affected buildings. The closest affected commercial properties span the ground floor to level 08 of the development, the industrial use premises to the north, and commercial premises to the east to the development. According to AS/NZS 2107, noise limits inside office buildings (open plan and general office areas) are 40 — 45 dB(A), and limits in inside small retail stores are 50 dB(A). Therefore the noise level from mechanical plant shall not exceed 55 dB(A) on the façade for an operable window and 65 dB(A) for fixed windows.

7.4.3 PLANT SERVICING INDIVIDUAL DWELLINGS

Noise emissions from any fixed domestic plant such air conditioners shall be controlled to comply with EPA Noise Control Guidelines 1254. Noise from any fixed domestic plant must not be audible within a habitable room of any other residence (regardless of whether any door or window giving access to the room is open) during prohibited hours prescribed by the Environment Protection (Residential Noise) Regulations 2008.

7.4.4 PLANT NOISE AT ANY AFFECTED PUBLIC ACCESS

There are no standards or policies for limitations of noise in a public access area and therefore the common noise requirement for public access is adopted in this project. The noise levels from plant shall not exceed 60 dB(A) in any public access areas, e.g., footpath, retail access, common areas, terrace areas or similar.

8 BUILDING FACADE GLAZING RECOMMENDATIONS

The impacts of external noise on the building façade window glazing were assessed according to the recommended internal noise design limits in Table 7.1 and Table 7.2. The constructions of window glazing were designed based on the various singular or combined existing noise sources impacting each façade. The current glazing designs do not include noise from plant within the proposed development.

As complete glazing area details were not available at this stage of the project, the following areas have been assumed:

• Ground Level Retail — 25 m2; • Level 01 Commercial — 24 m2 for existing façade, full height glazing all other areas; • Level 02 — Level 08 — Full height glazing throughout.

Room ceiling heights were assumed to be 3.8 meters for ground floor, 3 meters for Level 01 — Level 03, 2.7 meters for Level 04 — Level 08,.

Incident noise level spectra used for calculation of glazing requirements includes:

• Non-residential uses = greatest LAmax events for train horn and pass-by across all periods and highest 1—Aeq,30min from the Day period (07:00 — 18:00);

Glazing is selected to meet criteria specified in Table 7.1 and Table 7.2. The design criteria resulting in the stronger glazing specification is indicated in Table 8.1.

It is assumed that mechanical services will provide ventilation requirements within the retail and commercial tenancies of the development and operable windows will not be present, particularly given the sawtooth glazing design. Should any openings in the façade be present (e.g. ventilation duct openings), these should be located on the northern side of the development, shielded from direct rail noise exposure. Further assessment of such ducting is advised at later stages of the project to ensure internal amenity is not compromised due to noise ingress through façade openings.

Table 8.1 presents the configurations of all window glazing.

Acoustic Report

Given the sawtooth shape of the current glazing design, it is important to ensure that all glazing joins are properly sealed, as any acoustic weakness present at these joins may result in exceedance of the internal acoustic design criteria. Glazing requirements presented in Table 8.1 are based on assumed glazing areas presented above and room dimensions obtained from the drawings referenced in Table 3.1. Any changes to the room volumes or glazing areas will result in a requirement for reassessment of glazing configurations.

9 CONCLUSION

This report for the proposed development at 33 — 35 Stewart Street, Richmond, provides the acoustic criteria for the project in accordance with the relevant policies and standards. The construction of the fagade glazing was designed based on measurements of railway noise and noise coming from Richmond Station to achieve the appropriate levels of amenity.
