1.0 Introduction

1.1 Purpose

This risk assessment has been prepared to address initial site establishment works for

Sydney Metro City & Southwest Tunnel and Stations Excavation Works at the Sydney Metro

City & Southwest Project (TSE Works). These works are proposed to be undertaken by

John Holland CPB Contractors Ghella (JHCPBG) from 3 October 2017 until the Construction

Environmental Management Plan (CEMP) (SMCTSE-JCG-TPW-EM-PLN-002010) is

approved (scheduled to be no later than 4 December 2017).

The purpose of this risk assessment is to confirm that these works are of low environmental

impact and fall outside the definition of Construction under the Critical State Significant

Infrastructure Sydney Metro & Southwest Chatswood to Sydenham Infrastructure Approval

dated 9 January 2017 (Application no. SSI 15_7400) (Project Planning Approval).

1.2 Scope

This risk assessment covers the initial site establishment works at the following worksites:

• Chatswood Dive

• Crows Nest

• Barangaroo

• Martin Place (South & Bligh Street)

• Waterloo

• Marrickville Dive and Precast

• Victoria Cross North

The commencement of pre-construction site establishment activities from 3 October 2017 is

required to facilitate to the launch of tunnelling activities on schedule in 2018. Specifically site

establishment works are required at each of these sites to prepare and install site access

points, facilities and environmental mitigation measures that will enable Construction

activities to commence following DP&I approval of the Construction Environmental

Management Plan and Aspect Specific Management Plans. The completion of station boxes

and shafts in advance of TBM tunnelling works has significant environmental benefits,

particularly in terms of material input reduction.

Additional enabling works are required at the Marrickville Precast site to realise the

significant environmental and community benefits associated with the local production of the

tunnel lining segments (lowered carbon footprint, reduced traffic volumes and high local

content of materials and labour). The precast facility is on the critical path for the

commencement of TBM tunnelling from late 2018.

1.3 Planning approval pathway

1.3.1 Overview

Construction is defined within the Project Planning Approval as all physical work required to

construct the Project including demolition, other than the following low impact work:



a) survey works including carrying out general alignment survey, installing survey

controls (including installation of global positioning system (GPS)), installing

repeater stations, carrying out survey of existing and future utilities and building

and road dilapidation surveys;

b) investigations including investigative drilling and excavation;

c) heritage excavation and salvage works, subject to addressing related

requirements of this approval, including Conditions E10-E27;

d) treatment of contaminated sites subject to the recommendations of a Site

Contamination Report prepared in accordance with Condition E66.

e) establishment of ancillary facilities, except where demolition is required, in

approved locations or in locations meeting the criteria identified in Condition

A16 and Condition A18 of this approval, including constructing ancillary facility

access roads and providing utilities to the facility;

f) operation of ancillary facilities if the ER has determined the operational activities

will have minimal impact on the environment and community;

g) minor clearing and relocation of native vegetation, as identified in the EIS as

amended by the description in the PIR;

h) installation of mitigation measures including erosion and sediment controls,

temporary exclusion fencing for sensitive areas and acoustic treatments;

i) property acquisition adjustment works including installation of property fencing,

and relocation and adjustments of utilities to property including water supply

and electricity;

j) relocation and connection of utilities where the relocation or connection has a

minor impact to the environment as determined by the ER;

k) archaeological testing under the Code of practice for archaeological

investigation of Aboriginal objects in NSW (DECCW, 2010) or archaeological

monitoring undertaken in association with (a)-(j) above to ensure that there is

no impact on heritage items;

l) other activities determined by the ER to have minimal environmental impact

which may include construction of minor access roads, temporary relocation of

pedestrian and cycle paths and the provision of property access; and

m) maintenance of existing buildings and structures required to facilitate the

carrying out of the CSSI.

However, where heritage items, or threatened species, populations or ecological

communities (within the meaning of the EP&A Act) are affected or potentially affected

by any low impact work, that work is construction, unless otherwise determined by the

Secretary in consultation with OEH or DPI Fisheries (in the case of impact upon fish,

aquatic invertebrates or marine vegetation).

The low impact work described in this definition becomes construction with the

approval of a Construction Environmental Management Plan.”

The scope of the initial site establishment work is detailed in the risk assessment in Section

2.0. These activities clearly fall into the following categories under the definition of works that

can be undertaken in advance of construction:

“(g) minor clearing and relocation of native vegetation, as identified in the EIS as amended

by the description in the PIR;

(h) installation of mitigation measures including erosion and sediment controls, temporary

exclusion fencing for sensitive areas and acoustic treatments;….



…(j) relocation and connection of utilities where the relocation or connection has a minor

impact on the environment as determined by the ER

….(l) other activities determined by the ER to have minimal environmental impact which may

include construction of minor access roads, temporary relocation of pedestrian and cycle

paths and the provision of property access…”

With respect to the installation of acoustic sheds it is noted that Condition E49 states:

All acoustic sheds must be erected as soon as site establishment works at the facilities are

completed and before undertaking any works or activities which are required to be conducted

within the sheds.

This condition appears to exclude acoustic shed construction from site establishment works

however item (l) addresses other activities and JHCPBG’s assessment has identified these

as low impact and having significant environmental mitigation benefits associated with early

instillation.

1.3.2 Environment Protection Licence

An Environment Protection Licence (EPL 20971) has been issued to John Holland by the

Environment Protection Authority for the JHCPBG JV TSE works. Works that are required to

be undertaken outside of the standard working hours specified in Project Planning Approval

Condition E36 will be managed in accordance with the EPL.

1.4 Completion of this Risk Assessment

This risk assessment has been prepared based on the risk methodology adopted in the

CEMP, and is based on the risk matrix and structure documented in TfNSW’s Sydney Metro

Integrated Management System: Risk Management Standard (SM RM-ST-201/3.0).

The risk matrix detailed in Sydney Metro Integrated Management System: Risk

Management Standard (SM RM-ST-201/3.0) has been replicated in Appendix A.

During a review of the identified risks, uncontrolled risk was rated qualitatively and was used

to determine required controls. A risk rating was than assigned for the risk, assuming the full

application of controls and treatments.

Workplace health and safety risks (including encountering Asbestos) will be identified

through the Work Pack risk assessment and are not covered in this risk assessment.

1.5 Community notifications

In accordance with the Deed, the community will be notified of the commencement of site

establishment works in accordance with SMCWTSE-JCG-TPW-SH-PLN-002040-Community

Communications Strategy. This will include a letterbox drop to the defined adjacent area, to

be undertaken seven (7) days prior to the commencement of site establishment works at

each site. The notifications will be approved by TfNSW prior to distribution and will include a

description of the relevant site establishment works and also the relevant community contact

numbers and website details.

1.6 Management of site establishment

1.6.1 Site access requirements



Site access for design investigation works will be coordinated with TfNSW, with all access

requests being channelled through the nominated TfNSW contact (Linda Miller). Site access

arrangements will be confirmed prior to entering site. All personnel entering site must be

inducted. Any additional approvals associated with gaining access to site will be followed.

1.6.2 Induction

Prior to JHCPBG personnel or contractors entering the site to undertake design investigation

works, all personnel must undergo a JHCPBG TSE Project Specific Induction and site

access protocols must also be followed.

1.6.3 Environment procedures and hold points

This risk assessment has referenced a number of JHCPBG environment procedures relevant

to specific activities for implementation. Hold Points detailed in the referenced procedures

are not detailed in this risk assessment, but are located in the relevant JHCPBG procedures.

Hold Points will be signed out by the Project Environment Manager or delegate Environment

Co-ordinator using the specified forms. Out of hours works will be undertaken in accordance

with the EPL.

1.7 ER endorsement

Prior to site establishment works commencing the ER must endorse this risk assessment on

the front cover page.

Site Environment Plans (SEPs) for the site investigation works will be provided to the ER for

endorsement prior to commencement of the works. It is noted that this is not required by the

Project Planning Approval but will ensure the ER is fully informed of environmental controls

to be implemented.

SEPs that have been provided to the ER are detailed in Appendix B. Any updates to SEPs

and subsequent endorsements will be included on a SEP register and provided to the ER. It

is noted that this process will not require the ER to re-endorse the whole Site Establishment

Risk Assessment, this is simply an administration process to manage SEP revisions.

1.8 Amendments to this risk assessment

If there is a proposed change to the scope of works, this risk assessment must be amended

and resubmitted to the ER for endorsement prior to the amended scope of works

commencing. The scope of works endorsed by the ER can continue while the risk

assessment is reviewed by the ER. Amendments to text in this risk assessment will be made

in track change and provided to ER for information and ease of review along with the clean

final revision for endorsement. This is to allow an efficient review of the risk assessment so

that amended scope of works can commence within a timely manner.

Clearing/ trimming of vegetation

Trees located in the road nature strips on the Pacific Highway, Nelson Street and Mowbray Road adjacent to the worksite need to be removed to enable safe access into the worksite. Tree removal/ trimming is also required for utilities works.

Vegetation clearing in the rail corridor is to be undertaken in stages during separate rail possessions as determined by controlling/approving authority. As possessions are limited and a significant amount of work is required to prepare for possession works these works need to be undertaken during the pre-construction period. The initial removal of vegetation within the corridor during site establishment would include trees and shrubs between Mowbray Road and Nelson street and one tree immediately north of Nelson Street, this represents approximately 22 percent of the area within the rail corridor that requires vegetation removal.

These earthworks are vital to enable the construction of the precast facility and acoustic shed. Earthworks will prioritise the preparation of land for the precast facility (and the immediate area required for construction of the facility).

Continuing the earthworks and utilising existing hardstand into these areas immediately following the completion of the precast pad will minimise overall impacts from these works, minimising the requirements of stockpiling, duration and the delivery of materials and equipment.

The installation of the acoustic shed at the Marrickville precast worksite is on the critical path as it must be installed prior to 24hr operations. Due to CASA restrictions on crane heights the four 24m tall silos situated within the acoustic shed need to be installed prior to the acoustic shed construction. To prevent delays in the operation of the precast facility the steel work for the acoustic enclosure is required to be installed as early as possible. The early installation of the acoustic enclosure will provide a long-term benefit by allowing the facility to start operating earlier with lower noise levels.

The erection of the silos does not include their filling or operation.

Risk Rating


Construction of acoustic shed over part of the Victoria Cross north worksite.

• Excavation and

installation of acoustic

shed footings

• Piling works for

retaining walls


support and cladding

• Installation of

mechanical doors


such as power

• Drainage connection

to stormwater

The installation of the acoustic shed over part of the Victoria Cross north worksite is on the critical path as it must be installed prior to 24hr operations. From a constructability point of view the acoustic shed must be installed first to enable other key construction activities to occur once the shed is installed.

Noise from plant, equipment i.e. cranes, generators, rattle guns, excavators, hammers, trucks etc.

Install temporary hoarding walls including minor excavation for footings

• 3m hoarding wall to be

constructed on the

Miller street boundary

(length~30m)

The implementation of hoarding will minimise noise impacts from the operation of the station box during substantial works to sensitive receivers adjacent to site.

These works will be completed progressively around the site (staged approach). These will not be completed prior to clearing or the commencement of earthworks.
