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 2018 – 2019 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.

The Project was effectively completed in April 2019, and so data contained in this report does not extend to the end

of the 2018-2019 year.

2. PROJECT SCOPE

The Torrens Road to River Torrens Project has delivered 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 both committed $448 million to jointly fund a total

project cost of $896 million. The project commenced construction in August 2015 and was completed in April 2019.

The design 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 provides 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. 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 22



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 were 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 22



2. 7. KRA 4 SUSTAINABILITY

Sustainability Rating

T2T was 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 was required under the project specification.

T2T has been awarded a Leading Rating for both the Design Phase and the As

Built Phases, exceeding the requirements for the project.

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 were aligned with the Base case.

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

due to the use of soil nails instead of piles.

Figure 4: Water consumption.

Use of recycled stormwater from the City of Charles Sturt Waterproofing the West system

(http://www.charlessturt.sa.gov.au/RecycledWater) ceased in June 2018.

During this financial year the water use remained at a low level until the close of works, due to a continued demand

from landscape-related earthworks and manual irrigation for planted vegetation.

Figure 5: Spoil Disposal

During this financial year, the last remnants of T2T spoil was delivered to the Northern Connector project, as part of

DPTI’s North-South Connector. When access to the Northern Connector site was limited, spoil was exported to

Adelaide Resources Recovery (ARR) for commercial resale.

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.

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%.

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 was regularly used for decisions with sustainability implications throughout the project construction,

there was less of a requirement for its use in this financial year. It was used in the planning for the management of

contaminated materials.

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 William Street park, the design of which was approved by Council, was created over the 2019 summer and will

be opened to the public in May 2019.

Noise – Nightworks Planning

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

was predicted from the source allowing this to be transposed onto a map of the work area, identifying the houses

that may be affected by the works and what noise levels would be heard by the residents. This approach benefited

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

mitigate against those works early and notify the community in advance.

The nightworks process continued to be applied throughout this financial year. By the end of the works a total of 935

noise assessments had been carried out and associated permits approved.

Recycled Water

Recycled water was utilised on the project during 2017-2018, 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 ), was treated stormwater that had been passed through swales,

wetlands and a filtration system prior to storage within the aquifer ready for use.

Access to the recycled water ceased in July 2018. 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 design targeted

an increase of more than 20% above that of the original biodiversity, by planting over and above the usual one-for-

one replacement requirements.

Although the removal of trees was required for the project, four substantial Regulated trees originally intended to be

removed were retained through the detailed design process, either involving relocation or redesign of noise walls

http://www.charlessturt.sa.gov.au/RecycledWater

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

construction assisted the process by ensuring that access and works within these areas were strictly controlled

during this period of risk.

Environmental Discharges

During construction, there was a strong focus on minimising environmental discharges. Daily observations by site

supervisors and environment and community personnel were used to prompt the increased use of controls to

minimise impacts from the construction process.

• Water quality – The Water Sensitive Road Design methodology was 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 were avoided through the use of erosion and sediment controls, which

minimised 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 were used daily to keep the roads

clean.

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

construction activities was principally controlled via water carts; between 4 and 8 carts were in use,

depending on the weather conditions, and reducing as the works were progressively completed. Dust levels

were continuously monitored by 5 loggers located along the length of the site. These loggers carried out real

time monitoring and automatic messaging to site personnel so that activities could be adjusted or additional

controls can be applied if required. Recorded levels did not exceed 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 from the operational project. As these were constructed early in the construction

program, these provided 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, were minimised.

• One of the major challenges on the project was 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 were required to be treated as sensitive structures.

• To address vibration issues, a number of continuous loggers were installed throughout the project area.

These allowed for real time monitoring and messaging to site personnel to adjust their activities if required.

The monitors also allowed 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:

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

vibration criteria.

16 of 22



2. 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.

17 of 22



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 2018-2019 period included:

• Community Liaison Group meetings

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

community groups to discuss and exchange information about the project. The group played an important

role in facilitating two-way communication between the T2T Alliance and key community stakeholders. While

the last meeting of CLG was in late 2018, the group were subsequently kept informed via email as the last of

the works were being completed.

• Community Perceptions surveys

In the 2018-2019-year one (November 2018) community perception survey was completed.

• Project enquiry line

1169 calls have been received in the 2018-2019 year.

• Project emails

1443 emails have been received via the project email address in the 2018-2019 year.

• Construction notifications

282 construction works notices have been issued in the 2018-2019 year.

• A community celebration was held in the lowered motorway on Sunday 23 September 2018. Approximately

5,000 people took the opportunity to experience the lowered motorway before it opened to the public.

Around 1,000 cyclists, walkers and runners participated in the morning community ‘ride’ before the main

celebrations commenced.

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

and detours were also ongoing. During the 2018-2019 year, 125 individual meetings with stakeholders were

held.

Community Perceptions Survey

In November 2018, the T2T Alliance conducted its six-monthly standard nine-question Community Perception

Survey, to gauge the effectiveness of communications and our relationship with the local community. The survey

was emailed to community members who had contacted the project in the last six months, and they were asked to

rate our performance based on their interaction. 66 people responded to the November 2018 survey.

The results of this sixth survey have shown that the T2T Alliance again exceeded the minimum measure of the

performance spectrum of 50%, as shown in the graph below:

18 of 22



2.

The overall result of the last survey was lower than the previous surveys; the overall average rating score was 60.1%

compared with 78.6% for April 2018. It was noted that 27.2% of respondents rated T2T’s performance despite

having not had any correspondence via the project enquiry line, email address or in person throughout the survey

months (April – November 2018). Furthermore, the reduced result for November 2018 could be attributable to the

survey link being posted on the Tree 2 Tree Facebook page, the members of which were encouraged to voice their

opinions regarding changes to the landscaping design.

Respondents gave a lower overall rating for the process of dealing with the T2T Alliance than in the previous April

2018 survey: 61.7% rated the T2T Alliance between 61 and 100 for the process of dealing with the Alliance,

compared to 79.8% in April 2018. Likewise, 46.6% rated the T2T Alliance between 61 and 100 for the degree of

satisfaction with the outcome, compared to 65.0% in April 2018.

The areas with the more significant differences in scores are as follows:

• 63.3% of respondents were satisfied or very satisfied with the amount of information received, (compared to

81.9% in April 2018)

• 57.1% agreed or strongly agreed project information provided was meaningful and relevant (compared to

83.0% in April 2018)

• 68.7% agreed or strongly agreed project information provided as adequate to address the enquiry or issue

(compared to 87.5% in April 2018)

• 64.0% agreed or strongly agreed project information provided was factual / objective (compared to 78.8% in

April 2018)

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 were above estimate/forecast hours based on the

contractual total project hours, at 27.2%, as shown in the graph below:

Initiatives

The following initiatives were in place to assist in maximising the workforce participation target:

Retention

With the T2T Project ramping down and demobilising personnel the HR team spent time working with Supervisors to

assist with any required resourcing and retaining workers from the target group.

Pre-Employment Training Program

With the Landscaping package being the last remaining subcontract available to provide opportunities for

participation, the T2T Alliance worked with the Civil Contractors Federation (CCF) and the Landscaping contractor to

develop a Live Training Site where Certificate 2 in Civil Construction participants were provided on the job

experience and training to gain their qualification and receive exposure to a large construction site.

2. Subcontractor Management

The T2T Alliance continued to hold subcontractor meetings to inform requirements, commitment and reporting with

regard to target group employment, and offering assistance to achieve the target group percentages.

Industry Participation

The T2T Alliance continued to commit to the South Australian Industry Participation Policy to 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 continued to procure works in a manner

aimed at generating economic activity to build capability and grow the State’s economy.

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

All procurement packages for T2T were 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 included 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 had an SA Industry participation target of 90%. Performance exceeded the 90% target for almost the full

construction period. In this financial year, the percentage was consistently around 92%.

The Project’s Industry Participation performance to end of Feb 2019 is set out below.

Initiatives

SA Industry Engagement

As the procurement process occurred subcontractors were 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

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

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

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. The SA Industry Advisory Committee last met in January 2018, as the

requirement for new contracts was reduced as works progressed.
