1 Introduction 1.1 Project Description EMS was commissioned by FDC Construction (NSW) Pty Ltd to provide a Construction Noise and Vibration Management Plan prior to the project development works at the University of Sydney, Camperdown NSW (the site). The project comprises the demolition of the existing tennis courts and the construction of a museum building equivalent to three levels above ground and four basement levels. The purpose of this plan is to provide procedures to prevent excessive noise and vibration being emitted from onsite demolition, excavation and construction works which may cause unreasonable loss of amenity to nearby receivers. This report will include noise impact predictions based on the sound power level of the proposed onsite equipment for the project and their distance to nearby noise receivers. The purpose of these predictions is to serve as a guideline in preparing the suitable noise and vibration controls needed for the project. The Noise criteria will be established under the guidance of the EPA’s publication ‘Interim Construction Noise guideline’ and the vibration criteria will be adopted from the EPA’s publication ‘Assessing Vibration: a technical guideline’. Other relevant noise and vibration standards will also be presented in this report. 1.2 Site Location and Noise Receivers The site is located within the grounds of the University of Sydney around the area of tennis courts formerly known as the Women’s Tennis Courts. The rectangular shaped site is bounded by University Avenue to the east and south, Parramatta Road to the north and University Place to the west The site has (UoS) educational receivers to the south and west. South east of the site is the recreational receiver Victoria Park Pool. To the north of the site, across Parramatta Road, along Arundel Street are residential receivers generally 1 to 2 storeys high and the Urban Nest accommodation being 3 storeys high. To the north-east of the site is the educational receiver Glebe Public School, a religious receiver and mixed-use developments, many having a commercial ground floor with residential above.

2 Noise Monitoring

2.1 Background Noise Measurement Unattended noise monitoring was conducted between the 1st of 7th of May 2018, using the ARL EL-215 Noise Logger, to establish the Rating Background Level (RBL) for the immediate area surrounding the site. The unit was field calibrated prior to and after monitoring, and no significant drift was found. The noise logger was set to record ‘A’ weighted statistical sound pressure levels (SPL) with 15-minute intervals using a ‘fast response’. The noise logger was installed at a residential address on the front porch facing and Arundel Street and Parramatta Road with the noise logger’s microphone approximately 1.3 metres from the porch. The LA90 15 minute will be used to determine the Rating Background Level for the site and for the establishment of a relevant noise criterion. This statistical measurement LA90 is the sound pressure level measurement that is exceeded for 90% of the measurement period. The noise logger also collected the LAeq; this represents the level of noise equivalent to the energy average of noise levels occurring over a measurement period. The LA10 was also obtained; this is the sound pressure level that is exceeded for 10% of the measurement period.

3 Monitoring Results 3.1 Background Noise Results Table 3.1 outlines the LA90 background noise measurement results collected from the front porch of 3 Arundel St. No rainfall fell during the monitoring period as determined by Bureau of Meteorology (BOM) – Observatory Hill weather station.

4 Relevant Criteria 4.1 Noise Criteria

The Development Consent (Application No. SSD 7894) gives the following construction noise criteria:




EPA’s Interim Construction Noise Guideline The Noise Criteria will be in compliance with the EPA’s Interim Construction Noise Guideline, regulated by the OEH and is aimed to manage noise from construction work. The main objectives of the guidelines are:

• To protect the majority of residences and other sensitive land uses from noise pollution most of the time;

• Identify and minimise noise from construction works;

• Applying ‘feasible’ and ‘reasonable’ work practices to minimise construction noise; and

• Encouraging construction to be undertaken only during least sensitive noise periods.

Table 4.1 outlines the internal and external noise criteria for sensitive land use properties. Table 4.2 on the following page outlines the noise criteria for commercial and industrial premises. Table 4.3, further down, outlines the external Noise Criteria for the residential properties near the construction site. This information is applied to the Rating Background Level gathered during the noise monitoring period. Table 4.1 – Noise Criteria at Sensitive Land Use

Land Use Noise Management Level

LAeq(15 minute)

Classrooms at schools and other educational institutions Internal Noise Level 45 dB(A)

External Noise Level 65 dB(A)*

Hospital wards and operating theatres Internal Noise Level 45 dB(A)


Place of Worship Internal Noise Level 45 dB(A)


Active recreation areas (characterised by sporting activities which generate their own noise or focus for participants, making them less sensitive to external noise intrusion)

External Noise Level 65dB (A)

Passive recreation area (characterised by contemplative activities that generate little noise and where benefits are compromised by external noise intrusion, for example, reading, meditation etc.)

External Noise Level 60dB (A)

* EMS assumes a noise reduction of 20 dB(A) across the closed façade for educational institutions, hospitals and religious receivers.

Commercial and industrial premises Due to the broad range of sensitivities that commercial or industrial land can have to noise from construction, the process of defining management levels is separated into three categories. The external noise levels should be assessed at the most-affected occupied point of the premises: Table 4.2 – Noise Criteria at Commercial Premises

Land Use Noise Management Level LAeq(15 minute)

Industrial premises External Noise Level 75dB (A)

Offices, retail outlets External Noise Level 70dB (A)

Other businesses that may be very sensitive to noise. Where the noise level is project specific the proponent should undertake a special investigation to determine suitable noise levels on a project-by-project basis; the recommended ‘maximum’ internal noise levels in AS 2107 Acoustics – Recommended design sound levels and reverberation times for building interiors may assist in determining relevant noise levels.




Table 4.3 – Applicable Noise Criteria – Residents surrounding work site

Residential Premises

Time of Day Management Level LAeq, 15 mins

How to Apply

Recommended Standard Hours:

Monday to Friday 7:00 am to 6:00 pm

Saturday 7:30 am to 3:30 pm

No work on Sundays or public holidays

Noise Affected

RBL + 10 dB

Based on monitored levels, project specific management level is

Day: 07:00 – 18:00

65 dB(A)

The noise affected level represents the point above which there may be some community reaction to noise.

1. Where the predicted or measured LAeq (15 min) is greater than the noise affected level, the proponent should apply all feasible and reasonable work practices to meet the noise affected level.

2. The proponent should also inform all potentially impacted residents of the nature of works to be carried out, the expected noise levels and duration, as well as contact details.

Highly Noise Affected

75 dB(A)

The highly noise affected level represents the point above which there may be strong community reaction to noise.

Where noise is above this level, the relevant authority (consent, determining or regulatory) may require respite periods by restricting the hours that the very noisy activities can occur, taking into account:

1. Times identified by the community when they are less sensitive to noise (such as before and after school for works near schools, or mid-morning or mid-afternoon for works near residences

2. If the community is prepared to accept a longer period of construction in exchange for restrictions on construction times.

Outside recommended

standard hours:

Noise Affected RBL + 5dB

Evening: 18:00 – 22:00 58 dB(A)

Night: 22:00 – 07:00

48 dB(A)

• A strong justification would typically be required for works outside the recommended standard hours

• The proponent should apply all feasible and reasonable work practices to meet the noise affected level.

• Where all feasible and reasonable practices have been applied and noise is more than 5dB (A) above the noise affected level, the proponent should negotiate with the community.




4.2 Vibration Criteria

The effects of vibration can be divided into concerns over structural damage and human annoyance. This section will outline the relevant vibration criteria for the two concerns as requested in the Development Consent (Application No. SSD 7894), below:

i) Structural Damage Criteria

A Geotechnical Investigation report was prepared for the site in October 2016 by Douglas Partners. The Geotechnical Investigation report (ref: 85385.01) states “Normally, it is suggested that vibrations be provisionally limited to a peak particle velocity (PPV) of 8 mm/s at the foundation level of the buildings to protect the architectural features of the building and to reduce discomfort for the occupants. As there are no significant buildings nearby, vibration control for buildings is not expected to be an issue for the site.” In accordance with the Development Consent, EMS implements the structural damage criteria as outlined in the German Standard DIN 4150-3 (Structural Vibration: Effects of Vibration on Structures) for the both the nearest residential receivers across Parramatta Road and for the surrounding on-campus buildings, namely the heritage-listed Quadrangle and Fisher Library. Table 4.4 below gives a guideline value for short term vibration velocity at the foundation. Short term vibration is classified as vibrations which do not occur often enough to cause structural fatigue.

Table 4.4 - Structural Damage – Short Term Vibration (mm/s)

Figure 4.1

ii) Human Comfort Criteria The human annoyance vibration assessment should be undertaken using the EPA’s publication ‘Assessing Vibration: a technical Guideline’, based on the BS 6472 Standard. This Guideline covers the appropriate methods and criteria for the assessment of the intrusive vibration on living and working space. The guideline describes the following:

• The characteristics of vibration and associated effects that can cause community disturbance and concern to people, in particular the occupants of buildings.

• Criteria defining values of vibration to protect amenity.

• Procedures for the measurement and evaluation of vibration values and other associated emissions. A summary of the VDV criteria for human comfort limits are adopted from the EPA’s publication ‘Assessing Vibration: a technical Guideline and are presented in Table 4.5 below.

5.2 Construction Noise Impact Prediction

These impact noise predictions are all conducted on the “worst case” assumption with all the noise sources from each construction phase occurring simultaneously over a 15-minute period and with the majority of source operating continuously over the 15-minute period (except for the dump truck noise emissions). The noise calculations were carried out in the Acoustic Software SoundPLAN (version 8.0) with the noise sources placed towards the centre of the site, except for the landscaping construction stage. As some of the site phases may overlap, there may be slightly elevated levels should the most intense works occur simultaneously. EMS notes that the average LAeq noise level, averaged over a standard construction day, would likely be lower than the levels seen in Tables 5.2 – 5.6 as works would not likely be continuous throughout the day. A façade correction of 2.5 dB(A) was applied to the residential receiver R3. An absorptive ground surface was applied for the surroundings of noise receivers R1 and R2 and a reflective ground surface was applied to the surroundings of the receivers R3 – R6.




The residential properties, across Parramatta Road, to the north of the site are likely to be affected by noise levels that are, at times, above the Noise Management Level of 65 dB(A) during the excavation stage and structure stage, as seen in Table 5.4 below. The construction phase with the highest noise prediction is the excavation stage with the assumption that excavator hammering will be undertaken. The noise predictions also showed exceedances during the excavation stage at the UoS Fisher Library educational receiver. In order to lower the site’s noise emissions, particularly during excavation and structure phases, an acoustic barrier may be installed along the northern and southern borders of the site. However, a barrier will only reduce the predicted noise levels at receiver locations where the barrier blocks the line of site between the noise source and receiver. Due to the height of the proposed development and the height of the southern Fisher Library noise receivers, a noise barrier won’t be feasible for all the surrounding receivers as it would have to be significantly tall to provide a significant insertion loss. Section 6.4 describes the noise reduction that can be expected by acoustic barriers. Mounds of earth can also work as a barrier when plant items are located directly behind them. Due to the different phases of works and the proximity of the site to the surrounding residential receivers, the high intensity work phases (excavation and structure) are expected at times to generate noise levels that exceed the Noise Management Level of 65 dB(A) for northern residential premises and further mitigation measures would need to be explored and employed if complaints arise. Therefore, it is recommended that noise controls be implemented, especially for the residential and educational (University of Sydney) receivers surrounding the site work area. Tables 5.2 to 5.7 outline the noise impact prediction corresponding to the measured distance of the nearby receiver locations as displayed in Figure 1.1. Section 6 provides noise mitigation strategies for this project.

6 Noise Control The following noise mitigation plan outlined in Sections 6.1 to 6.7 shall be implemented to reduce noise levels from the project.

6.1 Construction Hours

The construction hours outlined in the Development Consent (Application No. SSD 7894) are outline below:

6.2 Best Management Practice (BMP) Noise Control Best Management Practice (BMP) is the adoption of particular operational procedures that minimise noise while retaining productive efficiency. The majority of the proposed noise mitigation recommendations will be adopted from the Interim Construction Noise Guideline and the Australian Standard AS 2436:2010 - Guide to Noise Control on Construction, Maintenance and Demolition Sites. The excavation and the construction phase of work should implement the following noise mitigation strategies:

• Implementing quiet work practices – Using equipment in ways to minimise noise, this includes reducing throttle setting and turning off equipment when not being used, i.e. trucks and saws.

• Distance – Provide as much distance from the noise source to the receivers as possible. Stationary machinery, especially, should be located at the south-eastern border of the site.

• Maintain equipment – Regularly inspect and maintain equipment to ensure it is in good working order. Also check the conditions of mufflers and keep the cutting saw sharp.




• Scheduling – Sensitive residential and educational receivers surround the site, therefore further time restrictions for intense work such as the rock breaking, drop sawing and hammer drilling works etc. could be utilised. See Section 6.1 for the scheduling given by City of Sydney for noisy activities.

• Limiting – Reduce the amount of machines or tools operating simultaneously near the receivers’ location.

6.3 Best Available Technology Economically Achievable (BATEA) Noise Control BATEA is a noise mitigation strategy based on equipment, plant and machinery modification to minimise noise output. The following BATEA strategies are to be implemented:

• Substituting quieter equipment – examining different types of machinery that perform the same function and compare the noise level data to select the least noisy machine, examination includes tyre noise, exhaust and compressor/fan noise. For example, rubber wheeled tractors can be less noisy than steel tracked tractors.

• Adjusting reversing alarms on heavy equipment to make them ‘smarter’ by limiting the acoustic range to the immediate danger area or a broadband style alarm sometimes referred to as a ‘quacker’ alarm (See C10. from the Development Consent (Application No. SSD 7894)) .

• High Performance Exhaust Mufflers could be fitted to the 30 and 50-tonne excavators working within the site. Silencers/mufflers are likely to reduce noise emission from 5 to 15dB.

• Pneumatic equipment is traditionally a problem – select silenced damped bits where possible.

6.4 Acoustic Screens

Acoustic screens or barriers can be an effective way to reduce noise emissions from the site. Barriers can be installed at either the location of the noise source or the location of the noise receiver. The reduction provided by the acoustic screen is determined by how much of the line of sight between the source and receiver is blocked. If the noise source is fully shielded a noise reduction of up to 15 dB(A) can be achieved. When the line of sight is only partially blocked the noise reduction can be up to 5-8 dB(A). Acoustic screens are more effective for stationary plant. EMS recommends material such as plywood (radiata plywood) of thickness 10mm or 15mm

The barrier should have the following properties:

• Material having at least 10 kg/m2 surface density.

• There should be no gaps or openings at joints in the barrier material.




6.5 Vibration Mitigation Control

Works that are anticipated to cause elevated vibration levels are hydraulic hammering from the excavator and a small amount of compaction rolling. However, vibrations generated from the site will experience significant attenuation due to the distance between the site and nearest receiver buildings. Vibration controls will not be an issue concerning the structural damage to the Sydney University buildings to the south and west of the site and the residential buildings across Parramatta Road. It should be noted that vibrations that are below threshold levels for structural damage may be experienced by pedestrians walking nearby, causing annoyance. When the phases of works which cause higher vibration levels are underway, further mitigation measures may need to be explored and employed should levels increase to such a point that complaints arise due to annoyance. The following practices should be implemented to reduce any potential vibrations affecting the surrounding structures:

• Place as much distance as possible between the excavation work and the surrounding pedestrians/properties. Distance is one of the most effective mitigation measures against vibration.

• Organise high impacting operations so as not to occur in the same time period.

• Conduct lower impact methods wherever possible, including the following:

• Orientation of the rock hammer away from property boundaries and into open excavation; and

• Operate excavator hammering in short bursts only, to reduce amplification of vibrations and the rise of noise.

6.6 Noise and Vibration Monitoring Due to the nearby residential noise sensitive receivers, we recommend unattended noise monitoring be undertaken at a nearby residential receiver either continuously throughout the project or during the first week of the excavation, substructure and structure stages to ensure noise levels are not excessive. Attended short term noise measurements may also be taken during the various stages, to ensure noise levels are complying with the noise criterion. Noise monitoring during high construction activities and/or after a complaint should be undertaken to monitor the noise impact at the affected receiver. Vibration monitoring is not required at the University of Sydney buildings surrounding the site nor the residential buildings across Parramatta Road due to the distance between site and the aforementioned buildings. Vibration monitoring should be undertaken adjacent to the pedestrian walkways surrounding the site should complaints arise. 6.7 Noise Monitoring Report The noise monitoring report will state the methodology of monitoring and display the established noise criteria. The noise monitoring results will show the measured daily average and peak construction noise levels (LAeq) in table form. In the Appendix there will be a noise graph displaying the 15-minute LAeq noise measurements over the entire monitoring period and all of these will be compared against the noise criterion. The table and graph of the noise results will be similar to that shown below and the report will contain a discussion of the results.

6.8 Complaint Management It is also important to interact with the nearby receivers and the community to ensure a good working relationship between the proponent and the community receive feedback on the project’s performance and work cooperatively towards the outcomes of benefit to the project. Table 6.2 gives a guideline approach to community consultation, notification and complaint handling. This guide is adopted from the Interim Construction Noise guideline and only some items are suitable for this project and provide measures such as letter box drops, project specific respite offer, phone calls and specific notification. Communication shall be upheld between the surrounding residential receivers, particularly the immediate northern, southern and western properties.




Table 6.2 – Standard consultation and notification guideline adopted from the Interim Construction Noise Guideline

Consultation and Notification Notification before and during construction

• Provide, reasonably ahead of time, information such as total building time, what works are expected to be noisy, their duration, what is being done to minimise noise and when respite periods will occur. For works outside standard hours, inform affected residents and other sensitive land use occupants between five and 14 days before commencement.

• Provide information to neighbours before and during construction through media such as letterbox drops, meetings or individual contact. In some areas, the proponent will need to provide notification in languages other than English. A website could also be established for the project to provide information.

• Use a site information board at the front of the site with the name of the organisation responsible for the site and their contact details, hours of operation and regular information updates. This signage shall be clearly visible from the outside and include afterhours emergency contact details.

• Maintain good communication between the community and project staff.

• Appoint a community liaison officer where required.

• For larger projects consider a regular newsletter with site news, significant project events and timing of different activities.

• Provide a toll free contact phone number for enquiries during the works.

• Facilitate contact with people to ensure that everyone can see that the Site Manager understands potential issues, that a planned approach is in place and that there is an ongoing commitment to minimise noise.

Complaints handling

• Provide a readily accessible contact point, for example through 24 hour toll free information and complaint’s line.

• Give complaints a fair hearing.

• Have a documented complaints process, including an escalation procedure so that if a complainant is not satisfied there is a clear path to follow.

• Call back as soon as possible to keep people informed of action to be taken to address noise problems. Call back at night time only if requested by the complainant to avoid further disturbance.

• Provide a quick response to complaints, with complaints handling staff having both a good knowledge of the project and ready access to information.

• Keep a register of any complaints, including details such as date, time, person receiving complaint, complainant’s phone number, person referred to, description of the complaint, work area (for larger projects), time of verbal response and timeframe for written response where appropriate




7 Conclusions A Construction Noise and Vibration Management Plan was prepared to satisfy the relevant standards for the proposed excavation and construction works to occur at the University of Sydney, Camperdown – The Chau Chak Wing Museum. The purpose of this assessment is to provide methods to prevent noise and vibration from the construction site causing unreasonable loss of amenity to nearby receivers and prevent vibration emissions disturbing or damaging nearby structures. The report has been prepared in accordance with and satisfies DA Condition B20 from the Development Consent (Application No. SSD 7894). The construction noise predictions from the site are provided in Section 5 of the report and outline that the noise levels will at times likely be exceeding the relevant management levels at the residential (across Paramatta Rd) receivers and at the University of Sydney educational receivers during the project. Section 6 outlines noise and vibration mitigation controls to be implemented on site. Appendix A provides for a Noise/Vibration Complaint Form template which can be used as seen fit. Appendix B provides the background noise measurement results graphs from the 1st – 7th of May 2018.
