2. 1. INTRODUCTION

This Torrens Road to River Torrens Project (T2T) Annual Sustainability Report sets out the social, environmental

and economic performance for the project for the 2017 – 2018 financial year. It also outlines the achievement of the

relevant Key Result Areas that are identified in the Project Alliance Agreement (PAA): Sustainability, Stakeholder

and Industry and Workforce Participation.

2. PROJECT SCOPE

The Torrens Road to River Torrens Project will deliver a 4 km non-stop roadway (incorporating a 3 km lowered

motorway) between Ashwin Parade, Torrensville, and Royce Avenue, Croydon Park, providing significant travel time

savings to commuters and freight.

The Australian Government and the South Australian Government have both committed $448 million to jointly fund a

total project cost of $896 million. The project commenced construction in August 2015 and is due for completion in

2019.

The design (including the project extension awarded in December 2015) includes:

A four kilometre non-stop section of roadway (incorporating a lowered road section) between Royce Avenue,

Croydon Park, and Ashwin Parade, Torrensville

A three kilometre section of lowered non-stop motorway from Overland Road, Croydon Park to Gawler

Avenue, West Hindmarsh

Project corridor width of nominal 56 metres

Parallel surface (at-grade) roads along the length of the lowered motorway to connect most local roads and

arterial roads to South Road

An Outer Harbor rail line overpass and track renewal from Queen Street Croydon to Chief Street Hindmarsh

Intersection upgrades at Pym Street, Torrens Road, Hawker/Hurtle Street, Port Road and Grange Road

Road bridges over the lowered motorway at Hawker/Hurtle Street, Torrens Road, Grange Road and Port

Road

Improved cycling and pedestrian facilities including a shared use bridge at Cedar Avenue and Chief Street

Landscaping and noise barriers.

The lowered non-stop motorway will provide three lanes in each direction, up to eight metres below the existing

surface of South Road. This design takes into consideration the future transport needs of Adelaide and allows for

connection to other parts of the non-stop North-South Corridor when the adjoining sections of South Road are

upgraded in the future.

2. 3. PROJECT STATUS

The T2T Alliance mobilised to site in June 2015, initially with the majority of staff engaged on the design of the

works. All services have been relocated or installed new and the lowered motorway construction, which began in

early 2017, was opened on 29 September 2018. Completion of the remaining works, including landscaping, will be

carried out with the lowered motorway and surface roads in full operation.

The following key milestones have been met this financial year:

July 2017•Port Road asphalt complete

August 2017•Hawker/Hurtle Bridge open to public

October 2017•Cedar Pedestrian Bridge open to public

November 2017•Torrens Road Bridge open to traffic

2. 4. SUSTAINABILITY COMMITMENT

Sustainable infrastructure is infrastructure that is designed, constructed and operated to optimise environmental,

social and economic outcomes over the long term. The T2T Alliance’s commitment to the sustainable design and

delivery of the Torrens Road to River Torrens Project is given in the Alliance’s Sustainability Policy:

5 of 23




2. 5. T2T SUSTAINABILITY OBJECTIVES

The following project sustainability objectives were developed in collaboration with representatives of the community,

to align with the policy commitments and project scope and to achieve a positive triple bottom line that demonstrates

a sustainable project.

Environmental

Minimising energy and environmental harm including noise, vibration and air quality whilst maintaining and

enhancing the local ecological value.

Social

Minimising impact of the livelihood of the local community while improving the quality of life in the local area.

Using this project as a catalyst to rebuild and enhance the community and social relationships whilst nurturing

and respecting cultural and historical significance of the area.

Economic

Utilises opportunities to minimise energy, materials and resources while maintaining business within state

borders.

Governance

Ensuring decision making within leadership is compliant with current legislation and meets the environmental,

social and economic objectives.

6. POLICY IMPLEMENTATION AND KEY RESULT AREAS

The commitments within the T2T Alliance sustainability policy are delivered, in part, through the project’s Key Result

Areas (KRAs) that are relevant to sustainability and through the implementation of the Infrastructure Sustainability

Rating Scheme. Relevant KRAs include:

KRA 4 Sustainability (encompassing environment, social and economic aspects of the project)

KRA 3 Stakeholders (social)

KRA 5 Workforce and Industry Participation (economic)

KRA 7 Site Performance (environment)

6 of 23




2. 7. KRA 4 SUSTAINABILITY

Sustainability Rating

T2T is registered for a rating under the Infrastructure Sustainability Council of Australia’s

(ISCA) IS Rating Scheme to drive sustainability initiatives and to optimise

environmental, social and economic outcomes for the project over the long term.

Ratings are given for the Design phase and the As Built (Design + Construction) phase,

and include, in rising order, Commended, Excellent and Leading.

An Excellent Rating is required under the project specification.

T2T has been awarded a Leading Rating for the Design Phase.

In the 2017-2018 financial year the Alliance has focussed on achieving a minimum of a

high Excellent As Built rating, consolidating information and data that supports the

commitments made within the Design submission of the Rating.

It is expected that the As Built rating will be achieved by December 2018.

2. Using Resources and Minimising Waste

The following graphs summarise the use of resources and minimisation of waste from the site for the reporting

period.

Figure 1: Electricity Consumption

Electricity consumption for this financial year, including that for the main site office and the various satellite facilities,

is moderately lower compared with the previous year.

The green bars identify the energy from renewable sources. While the 50% green power target was achieved for the

main site office up to the end of the previous financial year, it was not able to be purchased for the satellite facilities,

which were developed during this period. From July 2017 the renewed contract for the main site office did not

include Green power.

2.

Figure 2: Fuel, Oil and Grease Use (Transport and Stationary).

Diesel is the primary fuel, used on site primarily for plant and vehicle use. Stationary source use is relatively

consistent, and is principally associated with light towers and generators. Consumption in this financial year has,

after an initial increase, steadily reduced, reflecting the progressive completion of bulk earthworks.

2.

Figure 3: Materials Use

The above figure represents the use of principal materials for the full construction period, compared with the Base

Case (5% or initial concept) and the completed (100%) design.

The amount of asphalt for the As-built aligns with the 100% Design; the marginal increase compared with the Base

Case is because of the building of an additional traffic lane. 94% of the asphalt used contained 20% Recycled

Aggregate Product.

Due to the innovative design of the retaining wall using soil nails, the use of concrete was substantially reduced

compared with the Base case and the 100% Design.

As-built quantities of quarry products are aligned with the Base case.

Steel quantities are aligned with the 100% Design, and are substantially reduced compared with the Base case, due

to the use of soil nails instead of piles.

Figure 4: Water consumption.

Recycled stormwater from the City of Charles Sturt Waterproofing the West system

(http://www.charlessturt.sa.gov.au/RecycledWater) was in use between May 2017 and June 2018, principally for

compaction and dust control. There was a shortfall in meeting the 50% target, due to take-up by site personnel and

watercart logistics, in that potable and recycled water demand could not be mixed.

Figure 5: Spoil Disposal

During this financial year, T2T spoil continued to be delivered to the Northern Connector project, as part of DPTI’s

North-South Connector. While the spoil was originally delivered to a DPTI Material Storage Facility at Bolivar, which

was located on the Northern Connector site, deliveries direct to the Northern Connector site commenced in February

2017. When access to the Northern Connector site was limited, spoil was exported to Adelaide Resources Recovery

(ARR) for commercial resale, from August 2017.

The elevated figures for this financial year reflect the bulk earthworks for the lowered motorway.

For the full construction period, 99.1% of spoil was reused and consequently diverted from landfill, exceeding the

target of 95% diversion. The residue was directed to landfill because of contamination.

2.

Figure 6: Site Waste – Inert and Non-hazardous.

Site waste for this financial year has been predominantly asphalt and concrete, all of which has been recycled or

reused without processing, exceeding the 90% target. Approximately 97% of the remaining general mixed waste

has been diverted from landfill, through sorting and processing to create a waste-derived fuel for industrial use; also

above the target of 90%.

Figure 7: Office Waste.

Office Waste has been 100% diverted from landfill, exceeding the 60% target, through:

Recycling of paper and container deposit items

Composting of food waste/organics

Sorting and processing of general waste to create a waste-derived fuel for industrial use.

2. Initiatives

MCA (Multi-Criteria Analysis) Tool

The MCA Tool was developed by the T2T Alliance as a way to analyse differing options for major works and

evaluate the options against sustainable criteria. This allows the user to achieve a sustainability rating per dollar

spent to select the most sustainable option for the project.

While the tool has been regularly used for decisions with sustainability implications throughout the project

construction, there has been less of a requirement for its use in this financial year. It was used in the planning for the

use of recycled water and for the selection of the landscaping contractor.

Community Health

The William Street Park Community Initiative (Park Design) integrated the community’s wishes with regard to their

open space and recreation, and the design of the park was decided upon by those stakeholders and community

members in a meeting facilitated by the T2T Alliance Community Team.

The design for William Street park was finalised in August 2017 and has been approved by Council. The final design

was a collaboration of community ideas and will be communicated to the community via the Construction.

Noise – Nightworks Planning

Noise assessments are conducted by the Environment Team for all nightworks. The distance and level of the noise

is predicted from the source allowing this to be transpired onto a map of the work area, identifying the houses that

may be affected by the works and what noise levels will be heard by the residents. This approach benefits the

community, environment and construction teams where, by predicting the impacts from noisy works, we can mitigate

against those works early and notify the community in advance.

The nightworks process has continued to be applied throughout this financial year. By June 2018 a total of 836

noise assessments had been carried out and associated permits approved.

Recycled Water

Recycled water was utilised on the project during 2017-2018. The recycled water is used on the project for dust

management, construction and compaction purposes. The water, sourced from ‘Waterproofing the West’ Scheme

run by the City of Charles Sturt (http://www.charlessturt.sa.gov.au/RecycledWater ), is treated stormwater that has

been passed through swales, wetlands and a filtration system prior to storage within the aquifer ready for use.

It was found during this financial year that there was a reluctance on the part of some operators to use the recycled

water, resulting in a shortfall in usage. However, an ongoing benefit of this initiative is that the standpipe is now

established for other parties to utilise the water source.

Ecology

Landscaping for the project and fauna habitat creation along the River Torrens Linear Park and adjacent park areas

will improve biodiversity in the area with a greater focus on local native species. The T2T Alliance plans to not only

meet the legal and local council re-vegetation requirements, but also to achieve an increase of more than 20% above

that of the original biodiversity, by planting over and above these requirements.

2. Although the removal of trees has been required for the project, four substantial Regulated trees originally intended

to be removed have now been retained through the detailed design process, either involving relocation or redesign of

noise walls and/or services to avoid impacting the root zones of the trees. Establishment of Tree Protection Zones

during construction has assisted the process by ensuring that access and works within these areas are strictly

controlled during this period of risk.

Environmental Discharges

During construction, environmental discharges are likely to be more evident and there is a strong focus on

minimising these. Daily observations by site supervisors and environment and community personnel are used to

prompt the increased use of controls to minimise impacts from the construction process.

Water quality – The Water Sensitive Road Design methodology has been used to ensure treatment of

stormwater in site-based wetlands prior to discharge, during the operations of the completed project. During

construction, impacts to water quality are avoided through the use of erosion and sediment controls, which

minimise spoil affecting local roads and dirty runoff entering the stormwater system, and the processing of

collected site water in an on-site sedimentation process. Street sweepers are used daily to keep the roads

clean.

Air Quality – The project uses low speed limits and hard stand haul roads throughout the site, but dust from

construction activities is principally controlled via water carts; between 4 and 8 carts have been in use at one

time, depending on the weather conditions. Dust levels have been continuously monitored by 5 loggers

located along the length of the site. These loggers carry out real time monitoring and automatic messaging

to site personnel so that activities can be adjusted or additional controls can be applied if required.

Recorded levels vary throughout the day and can be exacerbated by dry and windy conditions, but they have

not exceeded the project criterion for the daily average.

Noise – The project design includes noise walls and other mitigating treatments to reduce community

exposure to traffic noise once the project is operational. As these have been constructed early in the

construction program, these also provide shielding for the community during the more disturbing works.

Vibration – Construction impacts to properties, including 3 State and 2 Local heritage properties and the

SAPN sub station, have been minimised.

One of the major challenges on the project is the close proximity of properties to construction works. Besides

the heritage-listed properties, approximately half of the properties adjacent to the project are classed as

“contributory heritage” and must also be treated as sensitive structures.

To address vibration issues, a number of continuous loggers have been installed throughout the project

area. These allow for real time monitoring and messaging to site personnel to adjust their activities if

required. The monitors also allow for more accurate observation and reporting which has helped ensure

compliance with standards and allowed the project team to provide a high level of reassurance to residents

and businesses.

To minimise the effect of construction vibration across the project, a range of other measures have been

implemented including:

16 of 23




2. o Identification of buffer zones for vibratory plant that allow operation without a risk of exceeding the

vibration criteria.

o Avoiding vibratory works within set distances of structures

o Operating equipment on the lowest effective vibration setting or employing static (non-vibratory)

methods for compaction

o Maintaining low speed limits for construction trucks and machinery

o Consideration of alternative construction methodologies where appropriate

o Providing advance notice to residents of any activities which may create noticeable vibration and the

expected duration of the activity.

2. 8. KRA 3 STAKEHOLDERS

The T2T Alliance is committed to responding to the needs of the communities and other stakeholders affected by the

project. This includes a catchment area of approximately 13,000 properties with community members who are likely

to be affected or interested in the project.

Community engagement activities for the 2017-2018 period include:

Bi-monthly Community Liaison Group meetings

The Community Liaison Group (CLG) provides a forum for local residents, businesses, local government and

community groups to discuss and exchange information about the project. The group meets monthly and

plays an important role in facilitating two-way communication between the T2T Alliance and key community

stakeholders.

Community Perceptions surveys

In the 2017/2018 year 258 community perception surveys were completed.

Project enquiry line

1,391 calls have been received in the 2017-2018 year.

Project emails

1,622 emails have been received via the project email address in the 2017-2018 year.

Construction notifications

465 construction works notices have been issued in the 2017-2018 year.

A Community Open Day and lowered motorway tour was held on Saturday 14 April 2018.

One on one meetings with residents and businesses directly affected by construction works such as

driveway access impacts have also been ongoing. During the 2017-2018 year, 136 individual meetings with

stakeholders have been held.

Community Perceptions Survey

In October 2017 and April 2018, the T2T Alliance conducted its six monthly community perception surveys, to gauge

the effectiveness of communications and our relationship with the local community.

A survey of nine questions was developed and members of the local community who had dealings with the T2T

Alliance in the past six months were invited to take part in the survey. One hundred and seventy seven (177) people

responded to the October 2017 survey and seventy eight (78) responded to the April 2018 survey.

The results of the fourth six monthly Community Perceptions Survey, held in October 2017, have shown that the T2T

Alliance exceeded the minimum measure of the performance spectrum in one area. A score of 80% was achieved in

accessible / easy to deal with.

18 of 23




2. The overall results of this survey, however, were poorer than the previous surveys, the overall average rating score

was 70.4% compared with 75.9% for April 2017. Given the amount and range of construction activities across

multiple work fronts and the construction fatigue being experienced by the community, the outcome is somewhat

expected.

Better results than the previous survey were achieved in the area of responsiveness to the community needs.

Respondents gave a lower overall rating for both the process and outcomes from dealing with the T2T Alliance than

in the previous April 2017 survey. In October 2017 70.9% rated the T2T Alliance between 61 and 100 for the process

of dealing with the T2T Alliance, compared to 77.3% in April 2017. While In October 2017 60.5% rated the T2T

Alliance between 61 and 100 for the outcome, compared to 74.5% in April 2017.

The areas with the most significant decline in scores are as follows:

71.3% of respondents were satisfied or very satisfied with the amount of information received, (compared to

80.5% in April 2017)

64.8% agreed or strongly agreed project information provided as adequate to address the enquiry or issue

(compared to 74.6% in April 2017)

70.3% agreed or strongly agreed project information provided was factual / objective (compared to 83.8% in

April 2017)

The results of the April 2018 survey were an improvement on all previous surveys:

April 2018 overall rating 78.6%

October 2017 overall rating 70.4%

April 2017 overall rating 75.9%

October 2016 overall rating of 72%

April 2016 overall rating 74%.

Better results than the previous survey (October 2017) were achieved in all areas of the survey.

Measurements of 80% of higher were achieved against:

Satisfaction with amount of information

Project information was delivered in a timely manner

Project information provided was adequate to address the enquiry or issue

Relevance and meaningfulness of project information provided

The T2T Alliance was accessible / easy to deal with

The T2T Alliance was open and honest in their communications with them.

Respondents also gave a slightly higher overall rating for the process of dealing with the T2T Alliance than in the

previous October 2017 survey. In April 2018, 78.9% rated the T2T Alliance between 61 and 100 for the process of

19 of 23




2. dealing with the Alliance compared to 70.9% in October 2017. Likewise in April 2018 65.0% was given for the T2T

Alliance between 61 and 100 for the outcome, compared to 60.5% in October 2017.

2. 9. KRA 5 WORKFORCE AND INDUSTRY PARTICIPATION

Workforce Participation

The project has a workforce participation target of 20% and stretch target of 28%, to increase the employment and

training of apprentices and trainees, Aboriginal people, displaced automotive industry workers, cadets and local

people with barriers to employment. Total target group hours are above estimate/forecast hours based on the

contractual total project hours, as shown in the graph below, and for this financial year have regularly been in excess

of the stretch target:

Initiatives

The following initiatives are in place to assist in maximising the workforce participation target.

Pre-Employment Training Programs

Pre-employment training programs are being run on behalf of the T2T Alliance, including Aboriginal Certificate 2 in

Civil Construction and Certificate 2 in Building Construction programs. Graduating students have been placed in

work experience directly with the T2T Alliance willing subcontractors. Throughout the work experience component

the focus is on enabling these students to continue in paid employment with our subcontractors.

21 of 23




2. T2T is also running a Live Training Site in conjunction with the Civil Contractors Federation (CCF) which works with

Certificate 2 in Civil Construction participants to provide a real live training site to gain their qualification and receive

exposure to a large construction site. This is due for completion in October 2018.

Subcontractor Management / Subcontractor Information Sessions

The T2T Alliance has been holding subcontractor meetings and information sessions to confirm requirements,

commitment and reporting with regard to target group employment, and offering assistance to achieve the target

group percentages.

Aboriginal Working Group

Regular meetings are being held to discuss strategies for the employment of Aboriginal people on the project.

DSD – Department of State Development

The Participation Implementation Team is coordinated by the T2T Alliance and the Department of State

Development. It is a working group of government department heads and T2T Alliance representatives that meet on

a monthly basis to assist T2T Alliance members and Subcontractors to access free services related to recruitment

and training. This contract is due for completion in July 2018.

Industry Participation

The T2T Alliance continues to commit to the South Australian Industry Participation Policy and will provide full, fair

and reasonable opportunities for industry to participate in the Torrens Road to River Torrens Project.

Under the South Australian Industry Participation Policy the T2T Alliance continues to procure works in a manner

that will generate economic activity to build capability and grow the State’s economy.

The project’s Industry Participation commitments continue to be monitored by the Office of the Industry Advocate.

All procurement packages for T2T are assessed in line with the State's Government's Industry Participation Policy

and reviewed by the T2T SA Industry Advisory Committee. Membership of the Committee includes external

representatives from the Office of the Industry Advocate, Civil Contractors Federation, Adelaide Business Hub and

the City of Charles Sturt, in addition to Department of Planning Transport and Infrastructure and T2T Alliance

representatives.

The project has an SA Industry participation target of 90% and stretch target of 100%. Performance has exceeded

the 90% target for almost the full contsruction period. In this financial year, the percentage was consistently around

96%.

The Project’s Industry Participation performance to end of June 2018 is set out below.

Initiatives

SA Industry Engagement

As the procurement process occurs subcontractors are made aware of the IPP - Industry Participation Plan

requirements through the EOI – Expression of Interests, RFP – Request for Proposal and Pre-award meetings. Once

awarded the contract a monitoring process through ongoing monthly reports etc. Continuing ongoing monthly contact

occurs with subcontractors that have been awarded work with the project.

A 15% weighting is applied in favour of local industry in the procurement evaluation process.

ICN Gateway

During the early years of construction Work Packages (for transparency, including all self-performed and single

source negotiated work packages) are published on the ICN Gateway website and the procurement status of

packages are regularly updated on the website to provide industry with current and up to date information.

The ICN Gateway was utilised less during this financial year, as the requirement for new contracts was reduced as

works progressed.

SA Advisory Committee

The SA Industry Advisory Committee for the Torrens Road to River Torrens Project was established to bring

valuable internal and external views on SA procurement and help to reach the broadest audience and optimise the

T2T Alliance’s processes to support and develop SA Industry. The SA Industry Advisory Committee sought to

support the T2T Alliance promote industry capability and maximise local industry participation in the project and

through procurement opportunities. Meetings have been every 2 months.

The SA Industry Advisory Committee last met in January 2018, as the requirement for new contracts was reduced as

works progressed.
