CPB Contractors | A Collaborative Approach to Organisational Leadership in Sustainability

ISCA 2020 IMPACTS REPORT FEATUREA collaborative approach to sustainability has been a long-term priority for CPB Contractors, the construction company of the CIMIC Group. By working collaboratively, CPB Contractors is building industry capability and leaving a positive legacy for clients and the community.
The contractor’s collaborative leadership in sustainability ensures infrastructure projects meet the needs of today, without compromising the future. 

A Collaborative Approach 

On the Logan Enhancement Project in Brisbane, a project which includes widening sections of the Logan and Gateway motorways, and constructing on and off-ramps on the Gateway Motorway, a collaborative approach with Transurban Queensland achieved an Australian first on this project by using an innovative EME2 (Enrobé a Module Élevé Class 2) asphalt product that increases paving durability, despite requiring a lower volume of the product in comparison to regular asphalt. Selected for its high strength and resistance attributes, more than 206,000 tonnes of the combined base and binder asphalt was applied to the Queensland roads project. The Infrastructure Sustainability Council of Australia (ISCA) has since verified that this is the single largest commercial use of EME2 in Australia. Collaborative innovations like this contribute to the broader market transformation of sustainable road construction.

In a collaborative approach to industry partnerships, CPB Contractors was the first corporate organisation to sign a 10 year commitment with Career Trackers to provide internships to Indigenous university students. Since 2011 more than 100 Indigenous students have completed an internship with many transitioning into our graduate program or into casual or full-time positions with our company. CPB Contractors will invest $2 million dollars into the program over the 10 year period. 

In partnership with Career Seekers, CPB Contractors has committed to support 25 interns each year over the next 3 years to focus on multicultural diversity while tackling the issue of underemployment of asylum seekers and refugees. The program supports participants, through a 12-week paid internship.

CPB Contractors is a founding member of Supply Nation and Social Traders, connecting Indigenous businesses across the country and supporting social enterprise to break the cycle of disadvantage and build resilience in Australian communities.

Building Industry Capacity

Industry advocacy is an effective way to build capacity and in 2019 CPB Contractors in conjunction with QLD Department of Transport and Main Roads (DTMR) facilitated an industry event with over 120m participants to promote an industry leading new Precast Geopolymer Concrete Elements specification MRTS270. This event extended on two similar low carbon concrete events organised by CPB Contractors in Brisbane and Sydney in the previous year, promoting the think tank - Beyond Zero Emissions, Rethinking Cement publication advocating practical opportunities for industry to pursue low carbon concrete options.
Following the achievement of a Leading ISCA rating on the Torrens Road to Torrens River Project (T2T) in South Australia, CPB Contractors in conjunction with the Department of Planning, Transport and Infrastructure (DPTI) assessed the financial and non-financial costs and benefits of implementing the IS Rating Scheme on the project. The assessment found that the initiatives arising from the IS Rating Scheme (and beyond contract specifications) were found to have created CAPEX and OPEX savings exceeding the cost of administering and resourcing the rating.  
Furthermore, several non-financial benefits have been attributed to the specification and implementation of the IS rating process on T2T.  A pubic version of this report has been uploaded onto ISCA’s website in June 2019, which has been recognised as an industry-first.
Building Internal Capacity

While the ISCA framework provides a common language to communicate sustainability targets, benchmarks and outcomes, it is important to ensure that there is common understanding within organisations of ‘why’ sustainability is important, ‘what’ appropriate solutions are available and ‘how’ to implement innovative solutions in project delivery.

In 2018/19, CPB Contractors undertook an ambitious training program across all Australian and New Zealand sites, delivering twenty-five face to face mandatory sustainability training sessions to senior leaders, tendering teams, project managers and environmental and sustainability employees. Facilitated by David Fox, CPB Contractors Group Sustainability Manager, and Glenn Hedges, CPB Contractors Sustainability Manager, the face-to-face training has increased the capability and technical knowledge of more than 300 employees. Training outcomes also included more increased project engagement on sustainability which has in turn led to stronger client engagement in many regions, increased knowledge sharing across projects and increased awareness of ISCA and its objectives.

To provide ongoing capacity building between our project teams, joint venture partners, suppliers and consultants, CPB Contractors facilitate a bi-monthly Infrastructure Sustainability Network tele-conference promoting knowledge sharing across project teams. 

Organisational Commitment

Maintaining momentum towards collaboration and capacity building in sustainability requires organisational commitment. CPB Contractors’ long-term commitment to sustainability is set out in the CIMIC Group Sustainability Policy. The Policy also includes our commitment to supporting UN Sustainable Development Goals.

CPB Contractors’ sustainability performance is publicly reported in the CIMIC Group Annual Report and is aligned with the Global Reporting Initiative standards for sustainability. The 2018 Annual Sustainability Report includes a review of the 17 UN Sustainable Development Goals and considers the alignment of the CIMIC Group activities with the Goals.


The 2020 ISCA Impacts Report is testament to ISCA's purpose, ‘ensuring all infrastructure delivers social, cultural, environmental and economic benefits’ both now and in the future.
