3 EXECUTIVE SUMMARY is proposing to develop the former Supreme Court site, located at 00-0 George Street, Brisbane QLD 000. The local authority is the Brisbane City Council (BCC). This report presents an assessment of the noise impacts on the proposed development and nearby noise sensitive locations, and establishes the required attenuation measures to control noise emissions and intrusion to acceptable levels. The noise assessment has been assessed in accordance with the requirements of Brisbane City Council s oise Impact Assessment Planning Scheme Policy (IAPSP) as well as the Department of Transport and Main Roads. Based upon the analysis presented in this report, the following conclusions have been drawn: Traffic noise from George Street, Ann Street, Adelaide Street and Riverside Expressway has the potential to adversely affect the development. Mechanical plant noise from nearby buildings also has the potential to adversely affect the development. To control the traffic noise and mechanical plant noise intrusion, the façade walls would need to be acoustically rated no less than R w. We would recommend that the glazing performances achieve the acoustic ratings specified in Section. and Appendix G of this report. The proposed development will install mechanical plant which may have the potential to adversely affect the nearby buildings. It will be necessary for the noise emissions to comply with the requirements of the IAPSP. At this stage of the development the actual plant types and sizes have not yet been selected. In these circumstances, it is recommended that a separate assessment of the noise impact of mechanical plant to be installed for the proposed development be undertaken at a later stage (e.g. Detailed Design Stage), when the mechanical specifications and noise data is available. oise predictions from mechanical plant should be assessed against the noise limits set out in Section. of this report. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

6 ITRODUCTIO is proposing to develop the former Supreme Court site, located at 00-0 George Street, Brisbane QLD 000. The site location is shown in Figure. The local authority is the Brisbane City Council (BCC). Renzo Tonin Ron Rumble has been commissioned by Bao Jia Development to undertake a noise impact study of the proposed development. This report presents an assessment of the noise impacts on the proposed development and nearby noise sensitive locations, and establishes the required attenuation measures to control noise emissions and intrusion to acceptable levels. The noise assessment has been assessed in accordance with the requirements of Brisbane City Council s oise Impact Assessment Planning Scheme Policy (IAPSP) and the Department of Transport and Main Roads (DTMR). SURROUDIG AREA AD PROPOD DEVELOPMET SITE An aerial photograph of the site and surrounding area is presented in Figure. The site is located within the Central Business District (CBD) which is primarily commercial in nature. The site is bounded by George Street to the north-east, Adelaide Street to the south-east, Ann Street to the north-west, and orth Quay to the south-west. It is noted that the site would also be exposed to the Riverside Expressway to the south-west and the Brisbane River beyond. Across Ann Street from the site is the Mercure Hotel Brisbane and the Grosvenor on George Hotel and other licensed premises. Commercial buildings are noted to surround the site on the remaining sides. The site is currently vacant and disused. Bao Jia Development proposes to demolish the existing building and develop the site into a new mixed-use development, comprising of: A -level hotel tower (anticipated to be a -star hotel); A 0-level commercial tower; An 8-level residential (apartment) tower; -level retail and commercial podium, which also houses the lobbies to the three towers, restaurant and function facilities for the Hotel, offices and the residential outdoor terraces and pool; and Associated utilities and car parks in the -level basement. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

7 The finished floor levels for the various components of the development are provided in Appendix A. IDETIFIED OI ISSUES Following an inspection of the site, a review of the proposed development and inspections of the adjoining land uses, the following noise issues have been determined as being of concern: oise intrusion from traffic along George Street, Adelaide Street, orth Quay, Riverside Expressway and Ann Street. It should be noted that George Street, Adelaide Street, orth Quay and Ann Street are Council-controlled roads, whilst the Riverside Expressway is a State-controlled road; oise intrusion from adjacent building plant noise; oise intrusion from the existing Grosvenor on George Hotel; and oise emissions from mechanical plant. oise Criteria. Internal noise levels.. Brisbane City Council IAPSP In order to assess the noise impacts of surrounding Council-controlled roads and existing mechanical plant impacting on the proposed development, the requirements of the Brisbane City Council (BCC) oise Impact Assessment Planning Scheme Policy (IAPSP) were considered. The IAPSP stipulates that intruding traffic and existing mechanical plant noise within the development should comply with the design sound levels recommended in AS/ZS07:000. Relevant design sound levels for the proposed development are summarized in Table.... Recommended Internal oise Levels as per Australian Standard AS/ZS07:000 The Australian Standard AS/ZS provides recommended internal noise levels and reverberation times based on the type and use of a space. The recommended internal noise levels are provided in terms of equivalent continuous A-weighted sound pressure level, L Aeq, and are intended as a guide for the design of occupied spaces due to constant / steady-state and continuous noise such as road traffic, nearby industrial noise and building services noise.

Department of Transport and Main Roads (DTMR) Policy for Development on Land Affected by Environmental Emissions from Transport and Transport Infrastructure (v) As the proposed development would be exposed to the Riverside Expressway, which is a Statecontrolled road, the development would be required to satisfy the requirements of DTMR. DTMR has recently released a new document in March 0, entitled The DTMR Policy for Development on Land Affected by Environmental Emissions from Transport and Transport 00 George Street Mixed Use Development oise Impact Assessment Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page 8

9 Infrastructure, which outlines internal and external noise criteria for new developments that could be affected by transportation noise. Version of The Policy was released in May 0, and is currently referenced in Module : Community Amenity within the Queensland Government Department of State Development, Infrastructure and Planning (DSDIP) State Development Assessment Provisions (SDAP), for matters relating to the assessment of the noise impact from a state-controlled road on nearby noise-sensitive developments. The Policy specifies the following internal noise criteria for sensitive spaces (note: the following noise limits are also cited in Module : Community Amenity of the SDAP): Habitable rooms at all times o The maximum -hour average equivalent continuous A-weighted sound pressure level over a period of -hours (L Aeq ( hr) (maximum hour over hours) shall not exceed dba. Offices: o The maximum -hour average equivalent continuous A-weighted sound pressure level over the normal operating hours (L Aeq ( hr) (operating hours) shall not exceed dba. External noise levels due to a State-controlled road at accommodation or residential developments shall not exceed: All façades: o Either 0dBA L 0 (8hr) façade corrected, if the measured L 90 (8hr) free field between 0pm and am is less than or equal to 0dBA; o Or dba L 0 (8hr) façade corrected, if the measured L 90 (8hr) free field between 0pm and am is more than 0dBA. Private open spaces: o Either 7dBA L 0 (8hr) free field, if the measured L 90 (8hr) free field between am and midnight is less than or equal to dba; o Or 0dBA L 0 (8hr) free field, if the measured L 90 (8hr) free field between am and midnight is more than dba. Passive recreation areas: o dba L 0 (hr) free field (between am and pm). External noise levels due to a State-controlled road at office developments shall not exceed: All façades: o 8dBA L 0 (hr) façade corrected (maximum hour during normal operating hours). Passive recreation areas: o dba L 0 (hr) free field (between am and pm). 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page 9 oise Impact Assessment

10 It is noted that the DTMR Policy internal noise limit of dba for habitable spaces over a period of -hours is more stringent compared to the noise limits outlined in the DTMR Road Traffic oise Management Code of Practice. The DTMR Code of Practice previously had nominated indoor noise limits in line with the recommended noise levels stipulated Australian Standard AS/ZS 07:000. On an additional note, the Brisbane City Council (BCC) had, and is currently, nominating the recommended noise levels in AS/ZS 07:000 in their oise Impact Assessment Planning Scheme Policy (IAPSP) please refer to Section... AS/ZS 07:000 recommends an indoor L Aeq noise level range of 0 to 0dBA for bedrooms within residences near major roads, and noise levels of to dba for living rooms within residences near major roads please refer to Section... A comparison of the Policy dba noise limit for all habitable areas (at all times) and the AS/ZS 07:000 recommended noise levels for bedrooms and living rooms show that the Policy noise limit is -points above the maximum recommended noise level for bedrooms (i.e. dba compared to 0dBA), and 0-points above the maximum recommended noise level for living areas (i.e. dba compared to dba) in AS/ZS 07:000. However, page 9 of the DTMR Policy states that the Queensland Development Code Mandatory Part. Buildings in Transport oise Corridors should ensure that the secondary noise criteria in the policy are achieved. Compliance with the secondary noise criteria should not be assessed at the development assessment stage... Sleep Disturbance It should be noted that the internal noise criteria provided in the previous sections are applicable to steady-state and constant noise. The previous noise criteria do not address the impact of transient noise sources, such as vehicles manoeuvring around the street corners, car horns, emergency warning sirens, rowdy patrons, etc. These events were observed to occur frequently at the site, and would have an impact on the hotel and residential components of the development. The most appropriate noise descriptor for quantifying transient events would be the average maximum noise level L Amax. Statutory documents such as the Environmental Protection Act 99 or the Environmental Protection Regulation 008 do not present any noise criteria for transient noise events. In the absence of specific criteria, appropriate limits have been derived which take into account the recommendations contained in the Environmental Protection (oise) Policy 008 (EPP oise). The aim of the EPP oise is to protect or enhance the qualities of the acoustic environment that are conducive to: Protecting the health and biodiversity of ecosystems; 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page 0 oise Impact Assessment

11 Human health and wellbeing, including by ensuring a suitable acoustic environment for sleeping, studying / learning, and / or recreation (including relaxation and conversation); and Protecting the amenity of the community. Of the above objectives, sleep preservation or creating a suitable acoustic environment for sleeping is generally considered to be the most important and most demanding requirement. Research has determined that the maximum noise level inside a bedroom or sleeping area due to short duration transient events should not exceed dba L Amax for nil sleep disturbances. This value corresponds to the World Health Organization (WHO) guideline internal L Amax noise level of dba for transient noise events in order to prevent sleep disturbance. By historical convention, the sleep criteria are applied only during the normal sleep period which extends from 0pm to 7am... Queensland Development Code MP. As the proposed development would be exposed to the Riverside Expressway, which is a Statecontrolled road, consideration would need to be given with regards to the Queensland Development Code MP.. The purpose of the Queensland Development Code (QDC) MP. Buildings in a Transport oise Corridor is to ensure any habitable rooms of Class,, and buildings located in a transport noise corridor are designed and constructed to reduce transport noise. The Code requires that each external façade of a habitable room be assigned a noise category which is dependent upon the future L A0 8hr traffic noise exposure at the façade. A summary of the noise categories is presented in Table..

12 Depending on the assigned noise category, the external facades is to then achieve a minimum R W requirement as specified in Schedule of the Code... -Star Hotel Brief It is understood that the hotel tower would be developed into a -star hotel. In this instance, the requirements for the indoor acoustic environment of the hotel may be more stringent, in order to reflect the quality of the hotel establishment. The Mandarin Oriental Hotel Group Product Standards and Guidelines (Mandarin Oriental Guidelines) was utilised in this assessment as a guide for the design of the indoor acoustic environment of the hotel tower. The Mandarin Oriental Guidelines generally provides internal noise criteria for various hotel spaces, in terms of C ratings, with the exception of restaurant spaces, which are provided in terms of a dba rating. These ratings are applied for steady-state noise such as building services noise. A summary of the internal noise level criteria stipulated in the Mandarin Oriental Guidelines is shown in Table.. In order to facilitate the comparison of the Mandarin Oriental Guidelines and the recommended levels in AS/ZS 07:000, the criteria are also shown in terms of dba noise levels.

13 ..7 Green Star Commercial Buildings It is understood that the commercial tower is to be developed to achieve - or -star Greenstar rating. IEQ- of the Green Star Office Design Version Technical Manual states that up to two points are awarded where it is demonstrated that for 9% of the building s et Lettable Area (LA), the design does not exceed the Satisfactory ambient internal noise levels provided in Table of AS/ZS 07:000, as follows: Building services design: One point is awarded where, within the entire base building general office space, noise from the building services does not exceed 0dBA L eq ; Overall building: One point is awarded where within the base building office space, the sound level does not exceed 0dBA L eq (assuming open plan offices).. oise Emissions from the Proposed Development It is understood that the proposed development would install mechanical plant which may have the potential to adversely affect the nearby buildings. Relevant criteria for the assessment of noise emissions from the proposed development are detailed as follows:.. Brisbane City Council IAPSP According to IAPSP, plant noise emissions will need to satisfy two requirements: Compliance with AS/ZS 07 inside any affected residence, and Avoidance of background creep. The derivation of noise limits consistent with these requirements is presented in Table.. Table.: Limits for Proposed Development Plant oise Emissions based on IAPSP (a) Compliance with AS07 Area Category (from AS 0 ) = R Internal noise limits (from AS/ZS 07) = 0dBA (L Aeq day) for private offices dba (L Aeq day) for open offices 0dBA (L Aeq day, L Aeq night) for hotel sleeping areas Attenuation of building facade (from IAPSP) = 0dBA (air-conditioned) External noise limits = 0dBA (L Aeq day) for private offices dba (L Aeq day) for open offices 0dBA (L Aeq day, L Aeq night) for hotel sleeping areas AS0-989 Acoustics - Description and Measurement of Environmental oise. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

14 (b) Avoidance of Background Creep Area Category = R Ideal background noise levels (from AS 0) = 0dBA (L A90 7am-pm) dba (L A90 pm-0pm) 0dBA (L A90 0pm-7am) Measured background noise levels (refer to Section ) = 7dBA (L A90 7am-pm) dba (L A90 pm-0pm) 8dBA (L A90 0pm-7am) The measured levels are higher than the desirable levels from the Code and therefore the desirable levels become the component noise limits for plant noise emissions. (c) IAPSP Component oise Limits = 0dBA (L A90 7am-pm) dba (L A90 pm-0pm) 0dBA (L A90 pm-0pm).. Environmental Protection Act 99 For air-conditioning equipment, Section 0U of the Act states that an occupier of a premises (at or for which there is air-conditioning equipment) must not use, or permit the use of, equipment on any day: a) Before 7am, if it makes a noise of more than dba above the background level; or b) From 7am to 0pm, if it makes a noise of more than dba above the background level; or c) After 0pm, if it makes a noise of more than dba above the background level. The above limits apply to air-conditioning equipment that would be installed for the proposed development. However, it is noted that the criteria determined in accordance to the BCC IAPSP are more stringent compared to the limits imposed in the Environmental Protection Act. AMBIET OI LOGGIG In order to determine the typical ambient noise levels in the area, environmental noise logging was carried out between Thursday 9 th August 0 and Friday th September 0. Two environmental noise loggers were deployed Logger was situated on the rooftop of the Former Supreme Court building with clear line of sight to the Riverside Expressway, whilst Logger was situated at the side of George Street with clear line of sight of the traffic along George Street. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

15 The locations of the loggers are indicated in Figure. The logger locations were chosen in order to obtain existing traffic and ambient noise levels, whilst still physically secure from any pedestrians walking past the site. The test instrumentation consisted of: Precision sound level meter Ti XL (S/ AA-07-E0, FW.), Precision sound level meter Ti XL (S/ AA-07-D, FW.), oise logger, Ti XL (S/ AA-0-D0); oise logger, Ti XL (S/ So. AA-0909-D, FW.); Rion C-7 sound-level calibrator: serial # 0889 The results for the noise logger are presented in Appendix B and Appendix C. It was noted that the instances of extraneous detected by the loggers were excluded in the results. The existing ambient results include values for the L A0, L A0, L Aeq, L 7 Amax and L 8 A90 averages for each of the day, evening and night periods. The results for Logger and Logger are summarized in Table. and Table. respectively.

Traffic noise from the Riverside Expressway was noted to be constant during the day and evening periods; Vehicle manoeuvring noise (e.g. vehicles slowing down, vehicles taking off, vehicles accelerating, car / bus horns, etc.) was significant at the corners of George Street, Ann Street and Adelaide Street; The occurrence of emergency vehicle sirens impacting on the site was significant (almost once a day, with up to times a day recorded during the logging period); Rowdy pedestrians along George Street this was noted to occur in the late nights and early mornings of Friday to Sunday; Road sweeping vehicles and refuse collection vehicles operating during the early hours of the morning. It was noted that the Grosvenor on George Hotel is located across Ann Street from the site. However, it was observed during the site inspections that noise from the bar is not audible due to traffic on Ann Street. During periods of traffic lulls on Ann Street, it was also noted that noise from the bar was only just audible. It is considered that noise from the bar would not significantly impact the proposed development. Averages are presented as the arithmetic means of the measured parameters over consecutive minute intervals throughout each period of the day, evening and night, apart from L Aeq data which is calculated as a logarithmic average and L A90, which is the average of the data set below the median in accordance with instructions from the QLD EPA. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

17 Traffic oise Intrusion. Traffic noise modelling and assessment methodology Continuous noise logging was undertaken at the site in order to determine the existing traffic noise levels please refer to Section for details of the logging. Traffic volumes and composition of the Council-controlled roads surrounding the site have been obtained from the BCC. The traffic volume for the Riverside Expressway was obtained from the Queensland Government Metropolitan Traffic Census website ( Census.aspx). The traffic composition for the Riverside Expressway was obtained from the Queensland Government Department of Housing and Public Works Transport oise Corridor mapping website ( Based on discussions with the Traffic Consultant for the project (TTM), it is noted that the traffic volumes for the Riverside Expressway would not significantly change in the next 0 years. Therefore it is assumed that the traffic volumes provided in the Queensland Government Metropolitan Traffic Census would be applicable for the modelling of the ultimate traffic scenario. A summary of the current and future traffic volumes for the roads surrounding the site is shown in Table.. Table.: Traffic data as provided by BCC and obtained from Queensland Government websites Road Traffic Volume AADT Existing Ultimate % Commercial Vehicles Speed, km/h Ann Street,000, George Street,000 7, Adelaide Street 8,000, orth Quay 0,000, Riverside Expressway adjacent Herschel St west-bound Riverside Expressway adjacent Herschel St east-bound Riverside Expressway adjacent Victoria Br west-bound Riverside Expressway adjacent Victoria Br east-bound,0,0,, 0, 0,,87,87 Turbot Street off ramp,7,7 0 Ann Street on ramp west-bound 0,77 0,77 0 Ann Street on ramp east-bound 0,00 0,00 0 As traffic composition data was not available, it was assumed that the % commercial vehicles on the Riverside Expressway exit ramps are the same as for the % commercial vehicles for the Riverside Expressway.

18 Road Traffic Volume AADT Existing Ultimate % Commercial Vehicles Speed, km/h Elizabeth Street off ramp,9,9 0 The road elevations and layout of both roads and the surrounding area contours have been obtained from the BCC website. Aerial photographs and observations during the site visits have been used to determine the placement of surrounding physical features. The CadnaA computer program has been used to model traffic noise. This computer program uses the CoRT 88 algorithm which is endorsed by DTMR. The model has been verified for this site by comparing the computer prediction from current traffic flows with the results of noise measurements conducted at the site. Future traffic noise exposures have been predicted at the facades of the proposed development buildings. Point receivers have been placed at m from the facades at a height of.m above the proposed floor RL s, which was provided by Zenx Architects. 7 Verification Of Computer Model The CadnaA computer model was verified by comparing the predicted noise level with the result at the measurement locations. The parameters used in the model verification are presented in Table 7.. Table 7.: Parameters used in the CadnaA model for current traffic volumes Parameters Riverside Expressway next to Herschel Street (Both Directions) George Street (Both Directions) 8 hour count 78,79,80 Percentage commercial vehicles (%) 7 Traffic speed (km/h) (Zone) 0 Microphone height RL (m).. Road surface correction (dba) 0 0 The predicted and measured values of the loggers are compared in Table 7.. It can be seen in this table that the differences between these values are within the ±dba tolerance. We therefore consider the road traffic acoustic model to be verified. CadnaA is an integrated software package for noise pollution evaluation developed in Germany by DataKustik. It has been configured to predict the extent of (i) road traffic noise intrusion by application of the CRT 88 algorithms and (ii) industrial noise emission using the ISO 9 algorithms. It is in use in more than 0 countries and has had widespread application throughout Australia.

As the existing 8- hour background noise level (L A90 8hr ) in Table 8. is greater than dba, the DTMR noise level criterion for passive recreational areas is dba L A0 hr (free-field). Using the offsets presented in Table 8., the facade noise levels have been predicted at the façades of the towers and podium buildings. The locations at which noise predictions were undertaken are attached in Appendix D. The highest noise exposure experienced at each receiver location is shown in Appendix E. Based on the traffic noise exposure levels shown in Appendix E, it is noted that the DTMR Policy L A0,8hour noise limit of dba at the façades of residential and accommodation developments is exceeded at the Residential and Hotel Towers of the 00 George development particularly where the façade faces the Riverside Expressway. However, the façade of the development will be designed to achieve the relevant internal noise limits suitable for the functionality of the internal spaces of the development please refer to Section. Taking into account the traffic noise exposure at the façades of the Hotel and Residential Towers, we note that the Hotel Tower and Residential Tower façades facing the Riverside Expressway (to the west, south-west and south of the site) generally fall under Category in accordance with the QDC MP.. The remaining façades typically fall under Categories and. 8. Private Open Spaces and External Recreational Areas We note a majority of the apartment balconies would be enclosed (i.e. like a wintergarden configuration). In this instance, the DTMR Policy criteria for private open spaces of dba L 0 (8 hour) façade-corrected would be achieved. However, we noted that the few apartment open balconies would exceed the limit for private open spaces. However, these residents would still have access to recreational areas (i.e. pool, residential outdoor terrace) that would comply with the DTMR Policy noise limit please refer to the paragraph below. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page 0 oise Impact Assessment

21 The predicted L A0 (hr free field) noise levels at Recreational Area and Recreational Area (please refer to Figure D. ) range from 0dBA to dba. Therefore the apartment residents and hotel patrons will have access to recreational spaces that comply with the DTMR Policy L 0,hour free-field noise limit of dba for passive recreation areas. 9 EXISTIG MECHAICAL PLAT OI ITRUSIO 9. Existing mechanical plant noise modelling and assessment methodology oise emissions from the adjacent building mechanical plant equipment were determined by modelling the noise sources, receiver locations, intervening structures and topographical features of the area using the CadnaA computer program. The program calculates the contribution of each noise source at each specified receptor point and allows for the prediction of the total noise from all nearby sources. The noise prediction takes into account: All noise sources occurring concurrently; Location of noise sources and receiver locations; Height of sources and receivers; and Separation distances between sources and receivers It was not possible to obtain noise data for all the mechanical plant equipment at the nearby buildings. Measurements have been conducted of large chiller units at a commercial building on Ann Street for a previous project (i.e. the Mincom Building). In addition, noise data of the cooling towers utilised for a similar-scale commercial development at Ann Street was utilised. The plant equipment used on the other nearby buildings is assumed to be of similar size to the chillers and cooling towers above, and therefore the measured levels and noise data have been used throughout the model. The locations of the plant equipment have been assumed using D maps and site inspections.

22 0 MECHAICAL PLAT OI EXPOSURE Using the CadnaA computer model, the mechanical plant exposures from the nearby surrounding buildings been predicted at the facades of the buildings within the proposed site. The façade noise levels have been predicted at several locations as shown in Appendix D. The highest L Aeq noise levels experienced at each receiver location are shown in Appendix F. EXTERAL BUILDIG EVELOPE DESIG Based on the various noise limits outlined in Section., it is noted that the most stringent noise limits affecting the façade design for the development are as follows: Residential Tower the DTMR Policy (please refer to Section..) maximum L Aeq,hr inside all habitable rooms at all times shall not exceed dba, Hotel Bedrooms the DTMR Policy (please refer to Section..) maximum L Aeq,hr inside all habitable rooms at all times shall not exceed dba. It is noted that the DTMR limit is the same as for the -Star hotel brief, Commercial Tower the Greenstar requirements (please refer to Section..7) the internal L Aeq sound level does not exceed 0dBA (assuming open plan offices), and Hotel public spaces and hotel facilities the -Star Hotel Brief (refer to Section..) the L Aeq noise levels inside the Lobby / Entry, Function Rooms, Pre-function Rooms, lounges, Business Centre and Executive Offices shall not exceed 0dBA. Using the noise exposures presented in Appendix E and Appendix F, the required attenuation performances of the building envelopes have been determined to meet the internal noise limits. For the acoustic design of the building envelope for this project, the approach adopted involves a review of the acoustic requirements from all relevant assessment parties (i.e. BCC, SARA, etc.). Where the requirements are impractical due on-site and current construction limitations, an alternative design is provided. ote that the recommended façade construction in the following sections does not take into account the impact of noise from mechanical plant installed within the development site. Some of the façade (especially the glazing) may need to be upgraded due to noise from mechanical plant located within the same tower or at the adjacent tower (detailed study to be undertaken during detailed design stage). 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

23 . Façade wall construction Taking into account the combined effect of traffic noise and mechanical plant noise impacting on the proposed development (i.e. due to existing surrounding mechanical plant), we recommend that the façade walls of sensitive buildings (i.e. Hotel Tower, Commercial Tower and Residential Tower) be constructed, such that the acoustic rating of the walls is no less than R w. Indicative wall constructions that may be acceptable are as follows: Minimum 0mm thick pre-cast concrete panels, or Drywall construction of minimum layers of 9mm fibre-cement (FC) sheeting externally of separate studs on minimum 0mm deep track, with layers of mm fire-rated plasterboard internally, and cavity insulation of 7mm, kg/m glasswool. Please note that the above constructions are recommended solely based on the tested performance in laboratory conditions, and do not take into consideration of penetrations, joints and interfaces with other elements (e.g. glazing, doors, etc. which would normally occur on site).. Glazing Specifications The required glazing performances for the various buildings within the site are presented in Table G. to Table G.. For the purposes of protecting the health and amenity of occupants of the Residential and Hotel Tower from excessive steady-state background noise levels (e.g. in the context of road traffic noise, industrial noise, etc.), and based on the statement in the DTMR Policy where the QDC MP. should ensure that the secondary noise criteria in the policy are achieved, a recognized industry practice is to design for building façades and configurations, as well as mechanical services plant, to achieve the recommended internal noise levels outlined in Australian Standard AS/ZS 07:000. It is noted that the Brisbane City Council (BCC) has cited the use of AS/ZS 07:000 in their IAPSP document, for the assessment of noise impacts of developments. In addition, it is noted that the DTMR Road Traffic oise Management Code of Practice (which was previously referenced for the assessment of road traffic noise impacts from state-controlled roads on nearby noise-sensitive developments, prior to the release of the current DTMR Policy) also recommended compliance with the design sound levels stipulated in AS/ZS 07:000. Given the limitations of glazing construction and acoustic performance on-site, alternative glazing specifications for the façade of the 00 George Street residential tower have been provided using the maximum recommended design noise levels provided in AS/ZS 07:000 as the target internal design limits. These alternative glazing specifications are shown in Table G. attached in Appendix G. It should be noted that the glazing acoustic requirements for the residential tower façades that are most exposed to traffic noise from the Riverside Expressway exceed the recommended acoustic performance ratings in the QDC MP.. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

24 As a general note, a performance rating of R W for the glazing can be achieved using laminated glazing systems (typically in an acoustically-rated framing system). Examples of glazing configurations that may achieve R W are: Option : IGU of mm float glass mm air gap mm float glass Option :.8mm laminated glass Examples of glazing assemblies that may achieve R W are: Option : IGU of.8mm laminated glass mm air gap mm float glass Option : 0.8mm laminated glass ote that the above glazing would typically need to be fixed (i.e. non-operable), with heavy frame construction (e.g. minimum mm thick aluminium wall thickness all around for hollow window frame profiles) and incorporating airtight seals for all framing profile components to prevent degradation of acoustic performance. Glazing assemblies with R W ratings of 7 to 9 would require fixed double-glazing assembly, with air gaps of mm to 0mm (for R W rating less than ). ote that double-glazing with air gap in excess of 00mm is typically required to achieve R W ratings of to 9. Examples of glazing configuration types are: 0.7mm laminated glass 00mm air gap.7mm laminated glass (R W 8).8mm laminated glass 00mm air gap 0.7mm laminated glass (R W 8).7mm laminated glass mm air gap mm float glass (R W ) 0.8mm laminated glass 0mm air gap mm float glass (R W ) Viridian VLAM TM Hush.8mm laminated glass (R W 9) ote that the above glazing would typically need to be fixed, with heavy frame construction (e.g. minimum mm thick aluminium wall thickness all around for hollow window frame profiles) and incorporating airtight seals for all framing profile components. In addition, the framing may need to be internally packed with acoustic insulation (e.g. polyester) to prevent degradation of acoustic performance. ote that the above glazing examples do not take into account any weaknesses with regards to the window assembly installation mechanisms or seals. It should be noted that the overall performance of a glazing system depends on the framing and building-in details as well as the glass configuration. When acquiring the glazing, a certificate should be obtained from the glass supplier which states that the glass and framing systems satisfies the R W ratings given in the above tables. It should be noted that the calculations for the internal noise levels within the development are based on standard acoustic theory, and has a tolerance of dba. The predicted noise levels do 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

25 not take into account any imperfections and acoustic weaknesses that may arise during the manufacturing, assembly, construction and installation of the façade, which may result in higher internal noise levels on-site. Please refer to the risk analysis table attached in Appendix H.. Residential and Hotel Towers Façade Construction based on QDC MP. The minimum R w ratings provided within the QDC MP. are as shown in Table..

26 It should be noted that the R w ratings in Sections. and., were higher than the recommended R w ratings provided in MP.. The QDC MP. typically considers noise exposure o of up to approximately 7dBA, with typical window sizes for the residential buildings (i.e. up to m glazed area). However it is noted that the traffic noise exposure for the proposed development is in the order of 7dBA (i.e. higher than the noise exposure considered in the QDC MP. document). In addition, it was noted that the proposed hotel and residential buildings incorporate large glazing areas, compared to typical residential buildings. We advise that the building façade construction should be designed to achieve the R w ratings provided in Sections. and., in order to sufficiently attenuate noise from road traffic, taking into account the site exposure to traffic noise, the layouts of the various habitable spaces relative to the Riverside Expressway and the size of the glazing to the habitable spaces. MECHAICAL PLAT OI EMISSIOS FROM DEVELOPMET oise from mechanical plant to be installed for the proposed development has the potential to impact upon nearby noise sensitive premises, such as the Mercure Hotel and the surrounding commercial buildings. ominal plant rooms and plant levels are shown in the Architectural Drawings. However, as the make and type of air conditioning equipment to be installed for the proposed has not yet been determined at this stage, it is not yet possible to recommend any specific noise control measures for mechanical plant. It is recommended that a separate assessment of the noise impact of mechanical plant to be installed for the proposed development be undertaken at a later stage (e.g. Detailed Design Stage), when the data is available. oise predictions from mechanical plant should be assessed against the noise limits set out in Section.. COCLUSIOS Based upon the analysis presented in this report, the following conclusions have been drawn: Traffic noise from George Street, Ann Street, Adelaide Street and Riverside Expressway has the potential to adversely affect the development. Mechanical plant noise from nearby buildings also has the potential to adversely affect the development. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page oise Impact Assessment

27 To control the traffic noise and mechanical plant noise intrusion, the façade walls would need to be acoustically rated no less than R w. We recommend that the glazing performances achieve the acoustic ratings specified in Section. and Appendix G of this report. The proposed development will install mechanical plant which may have the potential to adversely affect the nearby buildings. It will be necessary for the noise emissions to comply with the requirements of the IAPSP. At this stage of the development the actual plant types and sizes have not yet been selected. In these circumstances, it is recommended that a separate assessment of the noise impact of mechanical plant to be installed for the proposed development be undertaken at a later stage (e.g. Detailed Design Stage), when the data is available. oise predictions from mechanical plant should be assessed against the noise limits set out in Section. of this report. 00 George Street Mixed Use Development Q9-0F0 (Rev ) 00 George - oise Impact Assessment 0 October 0 Page 7 oise Impact Assessment
