1.0 Introduction
An Environmental Assessment Report (EAR) for Project Application MP10_0023
for bulk excavation and basement car parking was publicly exhibited for a period of four weeks between 7 July 2010 and 5 August 2010. In total 29 (10 agency) submissions were received in response to the public exhibition of the Project Application. The following key issues were identified with the proposal:
� the adequacy of the exhibited Noise and Vibration Assessment and predicted
noise levels;
� the adequacy of the exhibited Air Quality Impact Assessment and potential air quality and odour impacts;
� proposed construction traffic management arrangements;
� proposed hours of construction;
� water management and water quality impacts;
� contamination and remediation;
� waste management;
� urban design and public domain impacts; and
� relationship with, and potential impacts on, the Metro corridor.
The proponent Lend Lease (Millers Point) Pty Ltd (Lend Lease), and its specialist consultant team have reviewed and considered the Department’s comments, the agencies submissions, the City of Sydney’s submission and the public submissions and, in accordance with clause 75H(6) of the Environmental Planning and
Assessment Act 1979 (EP&A Act), has responded to the issues raised. This Preferred Project Report (PPR) should be read in conjunction with the Project Application EAR prepared by JBA Urban Planning Consultants Pty Ltd dated June 2010 and presents:
� further information and analysis with respect to a range of issues raised
in submissions that relate specifically to the development proposed by the Bulk Excavation and Basement Car Park Project Application;
� details the final Project Application, including a number of revisions to the
proposed scope of works; and
� a revised Statement of Commitments.
Key revisions to the Project Application include:
� inclusion of the southern retention wall down to rock level, which had been
inadvertently shown on the exhibited plans as a conventional wall;
� deletion of basement level CP6 to reduce the depth of excavation required by 3 metres from RL-27.000 to RL-24.000;
� re-allocation of car parking spaces across all levels of the basement parking
areas to ensure a maximum of 880 cars is shown;
� removal of some plant areas as a result of the car parking reconfiguration and
accordingly deferral of the final design of those areas to a future Project
Application (for built form), noting that the allocation of plant areas has always been proposed to be confirmed with future applications for buildings;
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
2 JBA Urban Planning Consultants Pty Ltd � 10051
� inclusion of spatial allocation of the Metro station/services box, resulting in a
marginal reduction in the size of the basement (station/service building box to be constructed by others);
� identification of deep soil zones and tree pits; and
� revision to the exhibited hours of construction.
In addition the updated reports appended to this PPR and the revised Statement of Commitments further detail the scope of amendments and ongoing commitments proposed by Lend Lease in the carrying out of this Project Application.
The following revised and supplementary plans and supporting documentation are
provided for clarification and are further discussed in Section 2.0:

Adjoining Landowners and General Public
As outlined in the exhibited EAR, Lend Lease has established a Stakeholder Engagement Strategy and is consulting with local residents and other relevant stakeholders as part of its ongoing community engagement program. The opportunity to participate has been provided through a number of direct and indirect mediums:
� the Barangaroo Display at Hickson Road attracted 3,000 visitors and 250
written comments;
� the Barangaroo Online Forum has attracted 1,400 unique visitors;
� some 6,500 have visited the Online Information Display;
� 400 people attended a series of four community forum events in Sydney’s
CBD, Parramatta and Caringbah;
� 9,000 people have visited the dedicated Barangaroo South Website since it
was launched on 16 June 2010 barangaroosouth.com.au; and
� Barangaroo South Information events and attendance at community meetings
have engaged with over 500 community members to date.
The extensive program of community engagement undertaken to date is aimed at
providing direct public feedback into the ongoing design process for Barangaroo South and enabling the community to develop a sense of ownership over the project. In relation to the Bulk Excavation and Basement Car Park Project Application specifically, Lend Lease has:
� issued the Barangaroo South newsletter in August 2010 to over 3,000 local
residents advising that the Project Application had been submitted to the
Department of Planning and detailing how the links could be accessed via the Barangaroo South website;
� notified an additional 85 individuals who have elected to be on the Barangaroo
South mailing list and 45 individuals from government departments and surrounding commercial properties and businesses;
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
4 JBA Urban Planning Consultants Pty Ltd � 10051
� engaged in face to face consultation with 14 building managers and tenants
from commercial properties and businesses surrounding the site to discuss the
upcoming works and potential impacts. All received a follow up communication
summarising the meeting and if necessary, any specific concerns relating to that property were addressed; and
� continued facilitating over 20 Community Forums and Information Sessions
with 500 + attendees throughout the duration of the project to discuss and
address issues arising from the proposed construction activities including dust, vibration, noise and traffic management.
Concept Plan Modification
Lend Lease submitted an EAR relating to the Barangaroo South Concept Plan Modification and Major Development SEPP Amendment to the Department of Planning on 6 August 2010. The Concept Plan Modification and Major Development SEPP Amendment EAR was on public exhibition until 10 September 2010. Lend Lease, and its specialist team, is currently reviewing and responding to the submissions received from
State authorities and agencies and the general public. As outlined in Section 6.1 of the exhibited EAR for the Bulk Excavation and Basement Car Park Project Application, the excavation and construction of the proposed basement levels is consistent with the approved Concept Plan (as modified). The current Project Application is a direct response to the combined effect of Conditions B3 and C1 of the approved Concept Plan and accordingly complies with the terms of the Concept Plan approval. The Project Application therefore does not rely on Lend Lease’s application to modify the approved Concept Plan and existing Major Development SEPP provisions. It should also be noted that the proposed bulk earthworks and basement car park construction works are also generally consistent with the Concept Plan Modification submitted to DoP and currently under assessment

Lend Lease’s detailed response to issues raised specifically in relation to the Project Application is provided at Appendix A (City of Sydney Council and State authorities and agencies) and Appendix B (public submissions). The following section provides a detailed response to the key issues raised in submissions. The Preferred Project – Stage 1 Project Application, including revised
Statement of Commitments is detailed at Sections 4 and 5 respectively.
3.1 Noise and Vibration
Issue
The extent and tenure of construction noise impacts due to the proposed
construction activities has been raised as a matter of concern by Sydney Ports,
DECCW, NSW Housing, Leichhardt Council, and in public submissions. The basis for concern includes:
� the background noise levels have not been derived appropriately;
� the predicted noise assessment criteria have not been derived appropriately and
accordingly the proposed noise management levels, particularly for residential premises, have not been estimated correctly;
� the proposed hours of construction have not been appropriately justified,
particularly as the appropriate assessment criteria have not been adopted;
� alternative construction methodologies that may result in lower construction noise impacts have not been adequately explored; and
� the omission of noise impacts from the proposed works on the temporary
Cruise Passenger Terminal.

Proponent’s Response
A supplementary Excavation and Construction Noise and Vibration Assessment and Environmental Construction and Site Management Report have been prepared (Appendix D and Appendix F respectively).
The supplementary stand alone Excavation and Construction Noise and Vibration Assessment has been prepared by Wilkinson Murray to determine the potential noise and vibration impacts at surrounding receivers (Appendix D). Noise objectives for construction have been established based on DECCW procedures and will be adopted by Lend Lease as targets to work towards in minimising noise impacts at surrounding residences and other identified sensitive receivers. Table 1 presents the surveyed noise levels for daytime, evening and night periods as defined in DECCW’s Construction Noise Guidelines. The locations of the surveyed noise logging sites are illustrated in Figure 1. Consistent with DECCW’s Interim Construction Noise Guideline, the daytime construction noise goal should not exceed the LAeq15min level by more than 10 dbA during standard construction hours, and 5dBA outside of standard construction hours. Tables 2 –
4 present the applicable noise criteria at residential, commercial (including the temporary Cruise Passenger Terminal) and pre-school receivers in the vicinity of Barangaroo South, predicted noise levels and identifies the expected exceedances.

Having regard to Tables 2 – 4, key observations are as follows:
Residential Receivers
� all construction noise levels are well below the highest construction noise level
of 75 dBA;
� the greatest potential exceedance at residences is likely to occur during
extended hours of construction on Saturdays; and
� Although within acceptable limits, the most potentially affected residences are:
- Hickson Road and other residences overlooking residences immediately to the east of the site particularly on Saturday afternoons;
- High Street and Dawes Street residences during periods when haulage of excavated materials to the Headland Park occurs;
- residences to the west of the site, represented by the Darling Island receivers.
- It is predicted that the noise from stationary plant such as the Bentonite plant will result in an exceedance of night criteria.
Commercial Receivers
� General compliance with the 70 dBA noise objective is expected, with
exceptions being, properties at Shelley Street where exceedances up to 7 dBA
are predicted which is within acceptable limits during standard construction hours.
� At restaurants and cafes at the northern end of Lime Street and the Shelley
Street precinct, construction noise levels up to 65 dBA are predicted.
Pre Schools
� Construction noise levels in play areas are predicted to comply with the 65
dBA noise objective for active recreation area.
� In the case of internal areas an exceedance of internal noise objectives by up to
6 dBA when windows are open is expected.
Temporary Cruise Passenger Terminal
� Maximum noise levels of up to 65 dBA are predicted. At these noise levels
effective communication will be achieved in the terminal at distance of up to 1m between persons in the terminal using a normal voice effort.
It has been determined that noise from construction activities during the day period will potentially exceed established construction noise management goals. The planning and management of construction activities must take into account the sensitivities of surrounding residents so as to minimise the impact of construction activities at these receivers. Subject to the implementation of the following management and mitigation measures noise impacts will be reduced to within acceptable levels through:
� installation of barriers between the construction site and the temporary Cruise Passenger Terminal;
� localized treatments of fixed plant such as the bentonite plant and installation
of barriers on the western (water) side of the site;
� installation of noise barriers on the southern and western boundaries of the
site;
� use of rocksaws and rippers, and smaller rockbreakers with quiet
“cityhammers”, where feasible;
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
18 JBA Urban Planning Consultants Pty Ltd � 10051
� provision of respite from noise producing activities during extended hours of
operation, where practicable;
� selection and maintenance of “quiet” equipment and plant with noise control
kits installed where practicable;
� auditing of plant to select equipment that generates the lowest commercially
available noise levels;
� appropriate planning of construction activities to provide respite to residences
from noise activities; and
� effective community consultation and complaints management.
Other issues such as cumulative noise impact and OH&S issues have also been reviewed and assessed and have been determined as being manageable. Furthermore, the impact from traffic along the road network is not considered to be acoustically significant due to the fact the majority of the truck will haul spoil
within the boundaries of the site rather than using the public road network. A revised Noise and Vibration Management Plan has also been prepared to assist Lend Lease in managing the environmental issues associated with this project. Further, the Environmental Construction and Site Management Plan has been updated to adopt the findings and the recommendations of the supplementary Excavation and Construction Noise and Vibration Assessment and to specifically detail the reasonable and feasible management measures and community consultation that will be employed by Lend Lease during construction works. In addition, Lend Lease has further considered alternative excavation construction techniques and these have been adopted as part of the supplementary Construction Noise Impact Assessment. While some limited percussive piling may be required as part of the works, it is envisaged that the majority of basement perimeter retention systems are now proposed to be constructed utilising cast in
ground/displacement concrete piling techniques such as reinforced concrete diaphragm and augured reinforced concrete piled wall systems. The elimination or significant reduction of percussive piling to the basement perimeter retention systems and its replacement with cast in situ concrete piling and wall techniques will significantly reduce the noise impacts arising from basement excavation works. The initial Construction Noise Impact Assessment was undertaken on the basis of extensive excavation of rock using heavy rockbreakers at the surface level across the majority of the proposed basement. Recently completed geotechnical investigative works have now determined that the extent rock at the existing surface is minimal and that the forecast construction noise levels arising from rockbreakers can be significantly reduced. Vibration associated with excavation activities is predicted to comply with
established human comfort criteria and not result in damage to surrounding structures.
3.2 Air Quality and Odour Impacts
Issue
The concerns raised by Sydney Ports, DECCW, Leichhardt Council and in public submissions in relation to air quality and odour have been categorised into four key issues: � the appropriateness of the baseline assumptions and criteria adopted to model
and predict air quality and odour impacts;
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 19
� the adequacy and range of the recommended control measures and any proposed contingencies;
� greater clarification regarding the number and location of exceedances predicted for each sensitive receptor; and
� the need to include additional properties into the area captured by the Air
Quality Impact Assessment (AQIA), and any subsequent air quality monitoring program, such as: - KPMG and ground floor tenancies;
- Macquarie Bank;
- King Street Wharf retail precinct;
- temporary Cruise Passenger Terminal; and
- Harbour Control Tower and Moores Wharf site.
Response
An updated AQIA has been prepared by AECOM in accordance with DECCW’s requirements and now provides a detailed modelling scenario whereby proposed controls are demonstrated to effectively control emissions, predicting no additional exceedances of the relevant assessment criteria (Appendix E). Modifications to the methodology and assumptions have been made to make the assessment better reflect site practices and conditions. Details of the original assumptions/parameters and the changes made in the revised assessment are summarised in Table 5 below.

Source: AECOM Revised Air Quality Assessment, 10 September 2010
In the context of the amendments to the AQIA, AECOM concludes “Dispersion
modelling using CALPUFF and meteorological data generated for the site using
TAPM (based on local meteorological data) was used to estimate ground level
concentrations of particulates (TSP and PM10), NO2, odour and contaminants
(primarily heavy metals, VOCs and PAHs) at sensitive receptor locations. No
exceedances of NO2, odour or contaminants were predicted”. In addition, the AQIA states that “Provided the on-site activities are implemented
in a manner consistent with the assumptions made by this modelling report (in
accordance with proven and industry standard dust and odour management
techniques) exceedances of DECCW criteria are not predicted to occur.”
Notwithstanding the above, Lend Lease’s detailed response to air quality and odour impact issues raised specifically in relation to the Project Application is provided at Appendix A (City of Sydney Council and State authorities and agencies) and Appendix B (public submissions). In response to the specific concerns raised by authorities and in public submissions: � Lend Lease’s revised AQIA has been updated to address the cumulative
impacts on Sydney Ports’ landholding and port operational facilities at Barangaroo South and concludes that no exceedances of accepted criteria are anticipated at the Passenger Terminal subject to the implementation of the industry standard management and mitigative measures.
� Whilst Lend Lease agrees that any air quality monitoring program should be expanded to include the Harbour Control Tower and Moores Wharf, air quality impacts at these receptors are likely to be predominantly derived from the works under MP 10_0047 Headland Park Early Works. Accordingly, air quality monitoring should be undertaken by the Barangaroo Delivery Authority as the proponent of the Headland Park Early Works.
� The AQIA has also been updated to more comprehensively address the cumulative impacts arising from the Headland Park works under MP 10_0047. The AQIA concludes that “On the basis of the cumulative pollutant
concentrations predicted by AECOM, which include emissions from both the
bulk excavation and emplacement activities, particulate emissions from the
bulk excavation works are not considered likely to substantially affect
particulate concentrations at Headland Park“. � The updated AQIA directly responds to DECCW’s technical specification and
has:
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 21
- provided a detailed modelling scenario whereby proposed controls are
demonstrated to effectively control emissions, predicting no additional exceedances of the relevant assessment criteria;
- been updated to specify the number of exceedances that are predicted for each sensitive receptor as required by DECCW;
- rechecked emission calculations, model configuration and model output files as required by DECCW. No errors have been found;
- adopted criteria specified in Table 7.2a of the Approved Methods for the Modelling and the Assessment of Air Pollutants in NSW;
- a Benzo(a)pyrene criteria of 0.0004 mg/m3 has been adopted in accordance with DECCW’s request;
- modified the CALMET meteorological data file to remove the perceived
over-reliance on TAPM data. The CALMET file was re-run using surface
observations only and TAPM upper air files. Only TAPM surface data
parameters not able to be sourced from surface stations have been used in the CALMET data e.g. cloud cover data;
- been updated to provide detail on baseline control measures to be
implemented which correspond to measures assumed by the dispersion modelling;
- been revised to include additional air quality management contingencies;
- modified the emissions inventory to ensure no double counting of PM10 emissions;
- added additional text to the AQIA to further justify the methodology used by AECOM to predict odour impacts; and
- added additional Volatile Organic Compounds (VOC’s) to the list of VOC’s
initially identified for the odour predictions (i.e. “all known substances”) as required by DECCW.
� The Lend Lease Remedial Action Plan proposes a number of odour control,
suppression and management strategies during the excavation of odorous material, where practicable.
� The AQIA commits Lend Lease to the treatment of contaminated material on
site (where required) within negative pressure temporary structures (fitted with appropriate controls).
� The AQIA has demonstrated that it is not necessary in all cases to undertake
excavation of odorous materials within negative pressure temporary structures
(fitted with appropriate controls) and that other odour mitigation techniques
may be more appropriate. Such alternate techniques are discussed in the updated AQIA.
� Financial compensation to adjoining properties for possible future maintenance
and cleaning is beyond the scope of the Project Application, particularly given
the demonstration of acceptable impacts arising from the Project Application, described above.
The Statement of Commitments has been revised to require Lend Lease to manage odour and air quality issues in accordance with the strategies identified in both the RAP and the updated AQIA. Further discussion of the human health impacts is also considered below.
3.3 Health Impacts
Issue
Submissions received from Sydney Ports, DECCW, Housing NSW and the public have raised the following health impacts as matters for concern:
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
22 JBA Urban Planning Consultants Pty Ltd � 10051
� confirmation required that the proposed bulk excavation works and basement
car park construction activities, and particularly the remediation works, do not pose a health risk to Sydney Ports operational staff;
� the protection of all site personnel, neighbouring communities and cruise
terminal passengers needs to be ensured, particularly where prolonged exposure to noise and dust emissions and contaminant vapours may occur; and
� general health impacts that may arise from air quality and dust impacts.
Proponent’s Response
The exhibited Health Impact Assessment prepared by AECOM has been updated to address the various authority and public submissions (Appendix I). In addition, updated Construction Noise and Air Quality assessments have been prepared as part of the PPR (Appendix D and Appendix E respectively). Refer to Sections 3.1 and 3.2 above for further detail. The updated Human Health Impact Assessment indicates that the main potential for human health impacts is considered to be through the inhalation of dust originating from contaminated soil. Dermal contact and oral ingestion of deposited dust are considered to pose insignificant risk of health impacts. Construction
workers, nearby residents and children staying at the childcare facility at 30 The Bond on Hickson Road may potentially encounter site derived dust or odours. To ensure that potential human health impacts on nearby sensitive receptors are minimised, the pollutant management measures listed in Table 4 of the updated Human Health Impact Assessment will be implemented. With the implementation of effective control measures, it is expected that the risk of exposure to harmful pollutant concentrations would be low and within acceptable limits. The updated Human Health Impact, Air Quality Impact and supplementary Construction Noise Impact Assessments set out appropriate management measures and mitigation controls to be implemented (where required) where prolonged exposure of site personnel, neighbouring communities and the temporary Cruise Passenger Terminal to construction noise, dust emissions and contaminant vapours, is anticipated. Further protection will be achieved through:
� most workers along Hickson Road and south of the site are indoors, reducing exposure duration and intensity through buildings;
� covering of trucks hauling soil within and from the site;
� on-site water-spraying of exposed soil areas for dust control;
� minimising the stockpiling of soil within the site;
� volatile emissions minimisation using, where practicable, vapour tents over relevant areas;
� placement of tarpaulins over stockpiles; and
� utilisation of perimeter hoardings and barriers
In addition, for workers on and adjacent to the site, health risks are considered moderate but manageable through:
� on-site dust control measures;
� contaminated soil work area zoning;
� use of appropriate personal protective equipment (mandated by works undertaken);
� dust migration off-site site being controlled; and
� further dilution of dust occurring prior to reaching receptors.
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 23
The Statement of Commitments has been amended to require Lend Lease to manage potential long term exposure of noise and dust emissions and contaminant vapours in accordance with the updated Human Health Impact, Air Quality Impact and supplementary Construction Noise Impact Assessments provided with the
PPR.
3.4 Water Quality Monitoring
Issue
Key issues raised by DECCW and City of Sydney Council in relation to water quality impacts include: � water management options have not been proposed; � criteria have not been provided to determine water treatment and discharge; � additional information is required in relation to water quality:
- water volume management;
- anticipated volumes of water generated on-site including potential volumes of groundwater and stormwater discharges;
- volumes of wastewater to be treated on-site;
- volumes for recycling/reuse; and
- volumes to be discharged to sewer; and
� the need for Lend Lease to demonstrate that best practice urban stormwater
management including WSUD principles will be implemented.
DECCW has requested that the following additional information be provided in relation to water monitoring:
� criteria for nominating areas/sources of site water as clean or contaminated;
� protocols and decision criteria for whether site water will be directed to
stormwater, a water treatment plant, to sewer or to a liquid waste facility;
� water discharge criteria and monitoring frequencies;
� details of a more intensive monitoring program for sediment basins, stormwater
discharges; reuse water and ambient waters;
� details of specific discharge and monitoring points for onsite waters including
collected groundwater seepage into excavations, sediment basins for clean or
contaminated areas, discharge points to stormwater drains, and ambient monitoring locations in Darling Harbour and Johnstons Bay;
� suitability of Johnstons Bay as a reference for turbidity data or a monitoring plan to determine its suitability;
� consideration of tidal currents, circulation patterns in Darling Harbour and the
position of stormwater discharge points with regard to monitoring location(s) outside the turbidity curtain; and
� potential criteria for wastewater discharges.
In addition, DECCW has requested Lend Lease provide the following additional information in relation to stormwater and sediment controls and operational procedures:
� better description of stormwater and sediment control measures for specific
locations on the site;
� sediment control systems to be implemented on site.
� an operational plan for contaminated water and sediment control systems;
� a fuller description of the water management measures;
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
24 JBA Urban Planning Consultants Pty Ltd � 10051
� proposed controls to prevent contaminated water being discharged to Darling
Harbour, including alternatives.
Proponent’s Response
The exhibited Water Quality Monitoring Requirements Report prepared by Worley Parsons has been updated to address DECCW’s and City of Sydney’s issues (Appendix H). The revised report nominates criteria for the future Water
Monitoring Plan. Lend Lease has also committed to the preparation of a detailed “Water and Stormwater Management Plan” which will be produced for the approval of DECCW to address:
� water volume management;
� anticipated volumes of water generated on-site including potential volumes of groundwater and stormwater discharges;
� volumes of wastewater to be treated on site;
� volumes of recycling/reuse; and
� volumes to be discharged to sewer.
The Water and Stormwater Management Plan will also detail;
� criteria for nominating areas and different sources of site water as clean or
contaminated;
� water monitoring protocols and decision criteria for whether site water will be
directed to stormwater, a water treatment plant, to sewer or to a liquid waste facility;
� water discharge criteria and monitoring frequency for parameters listed in the
“Water Quality Monitoring Requirements” document prepared as part of the exhibited EAR;
� details of an initial more intensive monitoring program for sediment basins,
stormwater discharges; reuse water and ambient waters to help determine potential water quality impacts and ongoing monitoring protocols;
� details of specific discharge and monitoring points for onsite waters including
for collected groundwater seepage into excavations, sediment basing for clean
or contaminated areas, discharge points to stormwater drains, and confirmation of ambient monitoring locations in Darling Harbour and Johnstons Bay;
� suitability of chosen reference site(s) based on turbidity data from a proposed
monitoring program;
� consideration of tidal currents, circulation patterns in Darling Harbour and the
position of stormwater discharge points with regard to the positioning of monitoring location(s) outside the turbidity (silt) curtain; and
� criteria development for wastewater discharges that would trigger a review of
water management systems.
In response to the City of Sydney Council’s WSUD related comments, and as stated in the exhibited EAR, Lend Lease is aiming to exceed national best practice in regard to reduction of suspended solids and nutrients. Gross pollutant traps, swales and bio-retention systems will be considered for the design of the treatment process (under future Project Applications). The Statement of Commitments has been revised to reiterate Lend Lease’s WSUD targets. Further, additional Commitments have been drafted to reaffirm Lend Lease’s commitment to implementing the recommendations of the revised Water Quality Monitoring Requirements Report.

3.5 Access and Construction Traffic Impacts
3.5.1 Issue
The City of Sydney noted that there are potential pedestrian movement issues associated with the landing of the Barangaroo Pedestrian Link as a result of the
reduction in footpath area adjacent to KPMG. The key issues raised in relation to construction traffic impacts include:
� the need to manage conflicts between construction traffic and traffic and
pedestrian movements when a large ship(s) has docked at the temporary Cruise Passenger Terminal at Wharf 5;
� a requirement for further details in relation to the intersection layout,
manoeuvring, queuing and operating arrangements proposed at the intersection of the on-site haulage route and the Wharf 5 access road;
� the cumulative impacts of surrounding construction works and particularly the
proposed Headland Park and Northern Cove development;
� the potential disruption to CBD vehicular, pedestrian and cyclist traffic during
peak periods, and particularly to public transport services and the need for Lend
Lease to provide greater detail of the proposed controls to be implemented during construction works.
3.5.2 Response
Lend Lease recognises the importance of the Barangaroo Pedestrian Link and is
facilitating its integration into the overall scheme for Barangaroo South. However, it should be noted that Transport NSW is responsible for the design and delivery of the Barangaroo Pedestrian Link. Notwithstanding this, Lend Lease has considered two design options that could potentially be further investigated in consultation and coordination with Transport NSW. Figures X and X demonstrate that Barangaroo Pedestrian Link will not be compromised by the project application works.

Figure 3 – Option 2- Sussex Street Bridge
In terms of construction traffic impacts, the exhibited Construction Traffic Management Report has been updated to address the various authority and public submissions (Appendix D). Following discussions with Sydney Ports Authority, the
Construction Traffic Management Plan has been updated to specifically address the key impacts on the temporary Cruise Passenger Terminal and Harbour Control Tower. The updated Construction Traffic Management Plan also describes in more detail the proposed temporary traffic management arrangements to be implemented to address traffic impacts during Sydney Ports’ operation of the temporary Cruise Passenger Terminal. Additional vehicular and pedestrian traffic surveys were undertaken during two large ship berthing days to determine the potential movement patterns to, from and around the site during typical berthing days. The surveys indicate that approximately 2,300 to 3,000 vehicles (buses, taxis and coaches) access the temporary Cruise Passenger Terminal over a 10 hour period, with peak traffic activity generally occurring between 9.00 am and 3.00pm. The temporary Cruise Passenger Terminal generates between 1,300 and 2,000
pedestrian movements on larger ship berthing days. Departing passenger movements generally occur during the morning period and arriving passengers occur during the afternoon period.
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
28 JBA Urban Planning Consultants Pty Ltd � 10051
To effectively manage the potential conflicts between construction vehicles and vehicle and pedestrian traffic on ship berthing days, Arup has recommended:
� the installation of signage to redirect passengers along Hickson Road to the
new temporary Cruise Passenger Terminal access point;
� maintaining of an existing access via Gate 4 to service the passenger terminal
cargo hall and the Sydney Ports Control Tower (HCT);
� installation of traffic signal controls that manage the conflict between
construction vehicles and Cruise Passenger vehicular and pedestrian traffic on
berthing days. A manual override function will be available to control personnel to manage any unusual peaks in activity.
In addition to the above, Lend Lease has committed to further consultation with Sydney Ports in relation to the preparation of an “Operational Protocol” regarding the traffic management arrangements where the haul route between the Stage 1 excavation site and the site of the Headland Park interfaces with the pedestrian and vehicular traffic servicing the temporary Cruise Passenger Terminal at Gates 4 and 5 (The Crossings). The “Operational Protocol” will be prepared prior to operation of The Crossings and will establish an agreed framework for their management on ship days during:
� unforseen events that lead to significant congestion of traffic either within
exiting or entering the terminal;
� a major breach of security within the passenger terminal requiring the closure
of the terminal;
� a major Health and Safety incident; and
� a major environmental incident.
Since exhibition of the Project Application, Arup has undertaken further analysis of
the proposed access and manoeuvring arrangements associated with the on-site
haulage route and the Wharf 5 access road to determine traffic flows and any
potential impacts on Sydney Ports operations, particularly during berthing days (Figures 4 and 5).
Figure 4 – Gate 5 access road construction traffic arrangements
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 29
Figure 5 – Gate 4 access road construction traffic arrangements
The analysis indicates that subject to the following measures and controls being
implemented, the proposed construction traffic management works will have minimal impact on Sydney Ports facilities and operations providing:
� relocation of the security fence line arrangements are implemented (to Sydney Ports’ satisfaction);
� provision of alternate temporary accommodation arrangements and facilities for
Sydney Ports staff upon the demolition of the Gate 5 gatehouse structure are provided;
� reconfiguration of the internal vehicle crossing at Gate 4 (refer Figure X) as a
priority control intersection with stop signs on the haul route and priority given to vehicles servicing ships;
� a double left turn lane within Hickson Road has been proposed for times when
taxis are queuing to enter the site;
� a right turn bay to accommodate up to 4 vehicles is proposed to allow
southbound through traffic to continue.
A number of the above arrangements will be required to be implemented within the City of Sydney Council’s Hickson Road road reserve. Lend Lease will obtain the required approval(s) under the Roads Act, 1993 from the City of Sydney prior to commencing the proposed road works. It should be noted that any required approval under Section 138 of the Roads Act, 1993 cannot be refused if it is necessary for carrying out the project and is required to be substantially consistent with the Project Application approval (refer Section 75V(1) of the EP& A Act). Arup has verified that the only other major construction project within the vicinity of Barangaroo South is the Headland Park and Basement construction works. Accordingly, the cumulative impacts of both Lend Lease’s Bulk Excavation and Basement Car Parking works and the Barangaroo Delivery Authority’s Headland Park Early Works have been assessed. At peak, there will be 104 peak hour car/utility/van driver trips, however the majority of these will occur outside the peak AM and PM periods. Modelling and intersection analysis indicates that traffic
flow and intersection operation will experience minimal disturbance, compared to existing conditions. A number of post construction and operational traffic matters have been raised by Transport NSW, Transport and Infrastructure, City of Sydney and in public
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
30 JBA Urban Planning Consultants Pty Ltd � 10051
submissions. Lend Lease’s detailed response to issues raised specifically in relation to the Project Application traffic matters is provided at Appendix A (City of Sydney Council and State authorities and agencies) and Appendix B (public submissions). The Statement of Commitments have been revised to reiterate Lend Lease’s commitment to undertaking the development in accordance with the
recommendations of the updated Construction Traffic Management Plan.
3.6 Waste Management
Issue
The DECCW considered the exhibited Waste Management Plan (Appendix R of the exhibited EAR) lacked sufficient detail. DECCW consequently recommended a condition of approval be imposed by the Minister for Planning on any Project Approval requiring Lend Lease to prepare a revised Waste Management Plan that addresses:
� the management of stockpiles, contamination and sediment;
� the in-situ classification of waste material, including the proposed sampling
locations and methodology that will be used to classify waste, and in particular contamination hotspots;
� the concrete crushing and screening plant proposed to be installed on site
during construction, and in particular:
- the location and dimensions of the concrete crushing plant;
- estimated quantities of concrete to be crushed per day;
- measures that will be employed to prevent or minimise dust emissions associated from concrete crushing; and
- measures that will be employed to prevent or minimise noise impacts arising from concrete crushing activities;
� the means and frequency of transporting waste within, and from, the site;
� the proposed de-watering process, including details of any on-site water
treatment plant; and
� any contingencies that will be implemented to manage and mitigate excavation
activities and contaminated soil treatment operations, particularly in relation to the expected volumes of materials excavated at the site.
In addition, DECCW requested Lend Lease comply with DECCW”s Classification Guidelines and commit to retaining all collected sampling and classification data for the life of the project.
Proponent’s Response
A revised Waste Management Plan has been prepared by Lend Lease’s consultant Arup to rectify and update minor anomalies in the exhibited waste management plan (Appendix J). The Statement of Commitments has been revised to require Lend Lease to preparea detailed waste management plan addressing all of the matters identified by DECCW in its submission, including compliance with DECCW’s Classification Guidelines (Section 4).

3.7 Relationship to Metro
Issue
Transport NSW expressed concern that the scope of bulk excavation activities and construction of the basement car park did not adequately address structural and engineering issues associated with the approved CBD Metro infrastructure (MP 09_0036).
Proponent’s Response
Coffey Geotechnics has prepared a short report that considers the implications of the Bulk Excavation and Basement Car Park Project Application on the approved CBD Metro (Appendix K). The report also addresses Transport NSW’s Sydney
Metro Network Line 1 Guidelines which aim to protect the structural integrity of CBD Metro related infrastructure by providing guidance for future development
along the approved corridor. The retention system required to support Lend Lease’s basement car park coincides with, and crosses over, the CBD Metro corridor’s “protection zone” – an area that must not be encroached upon by development unless it can be demonstrated that any proposed encroachment would not have unacceptable structural impacts to the CDB Metro corridor. In addition, the retention system is located immediately west of Hickson Road and is expected to coincide with the CBD Metro station box. The Margaret Street West entry and exit ramp also passes over the Metro corridor. The areas of overlap are illustrated in Figures 6 and 7.
Figure 6 – Extent of overlap between basement and Metro Corridor (ground plan)
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
32 JBA Urban Planning Consultants Pty Ltd � 10051
Figure 7 – Extent of overlap between basement and Metro Corridor (longitudinal section)
Coffey Geotechnics has concluded that bulk excavation and construction of
retention systems for the basement car park will not compromise the structural integrity of the Metro corridor and station box subject to appropriate structural options, such as temporary ground anchors and tie backs, being implemented during construction. In addition, Coffey Geotechnics has advised:
� vertical structural elements can be designed above and/or within the protection
zone without encroaching on the actual tunnels, and accordingly significant stress distribution within the protection zone or adjoining areas is not expected;
� groundwater levels are not predicted to change as a result of the Project Application works;
� no additional loads on the CBD Metro corridor are expected;
� no deformation of the CBD Metro corridor support structures are expected; and
� the construction methodology proposed for the vertical elements is not
anticipated to affect the CBD Metro corridor.
The Margaret Street West entry and exit ramp is proposed to be supported by piled foundations or other suitable footings on either side of the Metro corridor. Coffey Geotechnics has determined that vertical structural elements associated with the ramp will pose a low structural risk to the Metro corridor. Transport NSW has reviewed Lend Lease’s revised report and indicated general satisfaction with Lend Lease’s responses to the concerns raised during exhibition of the Bulk Earthworks and Basement Car Park Project Application. Notwithstanding, we note that recent Part 3A approvals within or adjacent to the CBD Metro Corridor have been conditioned to require proponents to enter into appropriate arrangements with Transport NSW to ensure that potential impacts of any approved development on the Metro Line 1 corridor are satisfactorily
addressed. Lend Lease would accept a similar condition of approval and accordingly a new Statement of Commitment has been drafted to reiterate Lend Lease’s commitment to working with Transport NSW to resolve any Barangaroo South related matter.
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010

The Statement of Commitments has also been revised to reiterate Lend Lease’s commitment to undertaking the Project Application in accordance with the recommendations of Coffey Geotechnics’ report.
3.8 Tree Pruning
Issue
The City of Sydney has raised concern that the proposed level of pruning will have a significant impact on the health, condition and form of the retained trees within the City’s Hickson Road road reserve. Notwithstanding the above, Council has recommended that the Tree Management Plan committed to by Lend Lease should be submitted to Council for approval to ensure all trees recommended for retention are protected in accordance with AS 4970 Protection of Trees on Development Sites.
Proponent’s Response
As outlined in Section 6.15 of the exhibited EAR, the Tree Health and Assessment Report (Appendix L of the exhibited EAR) has confirmed that there are no ecological impacts associated with the proposed removal and pruning of the identified trees and other vegetation on the site, and particularly those where limbs
and roots cross the site boundary and encroach into the Barangaroo site. Whilst the City of Sydney Council’s Tree Preservation Order (TPO) applies to all trees in the City of Sydney LGA and provides that:
� a person must not cut down, remove, wilfully destroy, transplant, lop, prune,
ring bark, injure or poison any tree above or below ground, without the written consent of Council; and
� a person must not wilfully or deliberately fail to plant, protect or care for a tree,
which is required to be planted, protected or cared for as a condition of
consent under the TPO, or fail to carry out any other activities required as a condition of consent under the TPO,
the level of pruning required to facilitate the proposed construction works is wholly within the Barangaroo site for which the Minister for Planning is the approval authority, under the provisions of Schedule 3 of the Major Development SEPP. Accordingly the TPO does not apply to works within the bounds of the
Barangaroo site. Although the TPO does not apply to the Barangaroo site, the environmental impacts of the proposed pruning can be supported as the trees within the Hickson Road and Sussex Street road reserves that overhang the site boundaries are:
� known for their ability to survive in hostile growing conditions, severe pruning
and in difficult environments;
� not representative of remnant vegetation found at Millers Point;
� not rare or an endangered species; and
� able to be readily purchased in advanced size from 75 litre bag size.
The exhibited EAR commits Lend Lease to the preparation of a Tree Management Plan to outline the proposed range of tree protection measures that will be implemented during works to minimise any impacts on the trees proposed to be retained. Lend Lease has committed to the preparation of the Tree Management Plan to DoP’s satisfaction (as the agency acting on behalf of the Minister for Planning) and generally in accordance with City of Sydney’s Tree Management Policy. Lend Lease’s proposes to submit the Tree Management Plan to DoP prior to the commencement of any tree related works. The scope of tree pruning therefore does not raise any adverse unmanageable impacts.

� suitability of chosen reference site(s) based on turbidity data from a proposed
monitoring program;
� consideration of tidal currents, circulation patterns in Darling Harbour and the
position ofstormwater discharge points with regard to the positioning of
monitoring location(s) outside the turbidity (silt) curtain. Note that the location
may not be a fixed point so that it can account for potential plume movement
under different conditions. Alternatively, more than one location may be
needed; and
� Criteria development for wastewater discharges that would trigger a review of
water management systems. These criteria will trigger operational responses
that help in ensuring licence conditions are not exceeded.
The Water and Stormwater Management Plan will also detail:
� Stormwater and Sediment Controls
- A detailed description of measures for stormwater and sediment control for
specific locations on the site.
- Silt curtain arrangements for the protection of Darling Harbour as a

incrementally increased should future research, change in Government policy or
actual events suggest that sea level rise will be greater than current projections.
5.10 Heritage
5.10.1 Non-Indigenous Archaeology LL Lend Lease makes the following commitments in relation to non-indigenous archaeology:
� Undertake a program of archaeological investigation with an excavation
director appointed to manage the program.
� Testing of areas of impact within the study area should be carried out to
determine the nature and depth of archaeological remains and to assist the development of an archaeological management strategy.
� Based on the archaeological integrity of the remains, a program of
archaeological salvage and recording will be required. Salvage would include sampling sections of the site, such as:
- Recording a number of sections of the later 19th century wharfage, notably the Grafton wharf.
- The maritime infrastructure, stores and reclamation in Portion 20, Block 2.
- If possible the remains of Henry Bass’ early shipyard and associated
reclamation and expansion of the site, but dependent on contamination issues.
- The nature of the area’s reclamation fills should be investigated – these will be present throughout the study area.
- Evidence for the early topography and natural landform and how this was modified through time.
� Develop a strategy for recording as much of the gasworks as possible within
the constraints of the contamination to human health and safety.
� The archaeological sampling and recording need to be undertaken according to
Heritage Branch guidelines and best practice archaeological methodologies.
This will then feed into the future interpretation and produce a detailed record of the site.
� The proponent or the Barangaroo Delivery Authority will need to provide a repository for the artefacts recovered from the site.
5.10.2 Indigenous Archaeology � A program of Aboriginal archaeological sub-surface testing will be undertaken
prior to the redevelopment of Barangaroo Stage 1.
� The program of sub-surface testing will be undertaken in partnership with the
Metropolitan Local Aboriginal Land Council.
� If any Aboriginal “objects” (as defined under the National Parks and Wildlife
Act 1974) are located during the course of the testing program, the
Metropolitan Local Aboriginal Land Council should apply for a Care Agreement with the DECCW to enable them to keep the objects.
� If, during the course of the redevelopment, any previously undetected
Aboriginal “objects”, artefacts or sites are uncovered, work must cease in the
vicinity of that object, artefact or site and further advice sought from the archaeologist who undertook the program of sub-surface testing.
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 43
� Interpretation of the Aboriginal history of the site will be included in the
redevelopment proposals.
5.10.3 Interpretation Strategy An Outline Interpretation Plan has been prepared by Tanner Architects and is located at Appendix FF. The Plan, which was prepared for the entire Barangaroo Stage 1 area:
� identifies the themes and messages considered significant to the Stage 1 area;
� develops a conceptual approach to interpretation of the Stage 1 area, using a
variety of means;
� proposes locations for specific interpretation to enhance the understanding of the heritage significance of the Stage 1 area; and
� recommends methods and media appropriate to the interpretation of the Stage
1 area.
Where appropriate interpretation options recommended in the Strategy will be implemented through the basement areas. During the excavation works any archaeological relics or other cultural artefacts identified will, where appropriate, be incorporated into future public displays.
The exhibited Interpretation Strategy prepared by Tanner Architects and dated
June 2010 included as Appendix FF in the Bulk Excavation and Basement Car
Parking PA1 Environmental Assessment Report Barangaroo Stage 1 (JBA Urban
Planning Consultants Pty Ltd, June 2010) may be amended from time to time.
5.11 Tree Removal Public Domain and
Landscaping
� A Tree Management Plan will be prepared to the Department of Planning’s
satisfaction with the relevant tree protection measures to minimise any
potential impacts on the trees proposed to be retained. The Tree Management
Plan will be prepared prior to commencement of any works that impact upon
trees.
The City of Sydney Council’s standards for the design and construction of
public domain elements over basement slabs will be considered where
appropriate during the ongoing design documentation process, particularly in
relation to:
- minimum soil depths between top of slab and finished levels of public
domain and soft landscaping;
- the ongoing management and maintenance of any waterproof membranes
to the basement slabs; and
- the need for drainage easements and covenants to cover public domain
stormwater infrastructure and other service infrastructure.
� The ongoing design documentation process will consider where relevant the
following City of Sydney Council policies as relevant to the scope of the
Project Application:
- Sydney Streets Design Code;
- Public Domain Manual;
- Exterior Lighting Strategy;

Hoardings will be treated with graphics and other designs consistent with an
overall coordinated high quality Barangaroo communications strategy to be
endorsed by the Barangaroo Delivery Authority.
5.12 Fire Engineering The fire safety of the basement will be developed to meet the Performance Requirements of the Building Codes Australia. This will be achieved either through meeting the Deemed to Satisfy Provisions noted in the BCA; or, where the design of the building falls outside of the prescriptive nature of the codes, through performance based fire engineering design. A Fire Safety Strategy will be prepared in consultation with the NSW Fire Brigade,
building certifiers, building insurers and relevant stakeholders to address:
� Safe egress provisions for all basement occupants. Fire engineered solutions
may be required to allow extended travel distances in order to address the
functional requirements of the site and constraints of the above ground urban landscape;
� The individual fire risks associated with loading docks, substations, data
centres, storage areas and fuel stores, whilst maintaining the functional requirements of the spaces; and
� Require wherever possible the central and coordinated placement of fire safety
measures having regard to the future above ground buildings’ fire systems. This will include:
- water storage for fire safety systems;
- sprinkler pumps; and
- hydrant pumps.
Stakeholder consultation will be undertaken early in the design process to provide
Lend Lease with the opportunity to appropriately resolve all fire safety engineering matters and proposed evacuation strategy(ies).
5.13 BCA The proposed development will comply with the BCA and where there are areas that do not comply with the deemed to satisfy provisions, an alternate solution prepared by a suitable qualified person will be prepared to ensure compliance with
the Performance Requirements of the BCA. Where items for which an alternate solution is prepared relate to Category 2 items under the Environmental Planning & Assessment Regulation 2000, approval will be required by the NSW Fire Brigade as part of the Construction Certificate process.
5.14 Access � The proposed design will utilize the Federal Disability Discrimination Act (DDA),
AS 1428 series, AS2890.6, BCA part D3 to develop appropriate design
documentation, to provide adequate access provisions for people with disabilities.
� Bovis Lend Lease and Morris Goding Accessibility Consulting will examine key
physical elements, to identify physical barriers, and incorporate solutions as a suitable response to disability statutory regulations.
� The design will be developed to ensure the principles of the DDA are upheld.
Under the Disability Discrimination Act (DDA), it is unlawful to discriminate
against people with disabilities in the provision of appropriate access, where
the approach or access to and within a premises, makes it impossible or
Bulk Excavation and Basement Car Parking � Preferred Project Report | September 2010
JBA Urban Planning Consultants Pty Ltd � 10051 45
unreasonably difficult for people with disabilities to make use of a particular service.
� The car parking design will comply with the requirements of AS2890.6 and
include requirements for accessible paths of travel and seamless integration within the basement car parking under the draft DDA Premises Standards.
� The developed design of the basement car parking will provide a consistent
accessible environment through detailed design and planning of integrated
accessible network of paths of travel to the precinct and associated ferries and
public transport. This will include the provision of appropriate continuous
accessible paths of travel, circulation areas, signage, lighting, handrails, stairs,
ramps, lifts, accessible car parking layout and positioning, accessible pedestrian and transport linkages.
� The statutory & regulatory guidelines to be encompassed in the developed
design to ensure effective appropriate and safe use by all people including those with disability will be in accordance with:
- Federal Disability Discrimination Act (DDA)
- Draft DDA Premises Standards
- Building Code of Australia (BCA) Part D3
- AS 1428.1 - 2009 (General Requirements for Access)
- AS 1428.4.1 - (Tactile Ground Surface Indicators)
- AS 1735.12 - (Lift facilities for persons with disabilities)
- AS 2890.6 - (Car Parking)
5.15 Future Project Applications
� Lend Lease commits to the following matters in future project applications (as
relevant) application of the NSW Industrial Noise Policy (INP) in the formulation
of noise objectives for static plant and equipment associated with the future
development of the site.
