Through our end-to-end capability and financial strength, we drive technical and operational certainty across each project’s lifecycle.

We give assets a performance advantage and provide better end-user experiences; create infrastructure with future generations in mind; and unlock resources and renewable energy sources for maximum productivity and output.

At the core of our commitment to client success and sustainable communities is being a trusted partner – responsive, collaborative and disciplined.

End-to-end capabilities

Our family of industry leaders is proven across diverse disciplines, sectors and environments.

CIMIC Group comprises our construction businesses including CPB Contractors, Leighton Asia and Broad, our mining and mineral processing companies Thiess (joint control) and Sedgman, our services specialist UGL and our infrastructure development company Pacific Partnerships – all supported by our in-house engineering consultancy EIC Activities. We also have an investment in Ventia, one of the largest essential services providers in Australia and New Zealand.

With integrated capabilities, our Group is uniquely equipped to provide seamless whole-of-life solutions and optimise outcomes.
Our collective experience spans sectors such as aviation, building, defence and security, education, health, resources, ports, power and energy, transport, tunnelling and water. Within these, our capabilities deliver the full spectrum of services, from feasibility, design, planning and investment; to manufacturing and construction; to operations, maintenance, upgrades and asset management; to rehabilitation and decommissioning.

How we work

We connect our leading capabilities with the skills and experience of our clients, partners, suppliers and wider stakeholders, because we believe we realise the greatest results together.

We operate according to our Principles, and the core of our success is disciplined project and business management. 

Our operating companies leverage advanced management and information systems to drive repeatable excellence. Where relevant, we work on shared platforms and processes, underpinned by shared policies, to create unmatched efficiency and consistency, and facilitate innovation and knowledge-sharing.

The challenges that inspire us include those presented by innovation and sustainability. We are finding better ways to embed safety and resilience, reduce emissions, waste and costs, and increase productivity and resource efficiency – generating community, economic and environmental value.

Our people are leaders in connecting clients with unmatched engineering solutions, driving value through disciplined project management including the effective management of large, diverse workforces, providing direct investment solutions through Pacific Partnerships, and optimising project cost management through plant and equipment supply.

For communities, this includes the key services needed to support daily life, health and wellbeing, such as water, power, transport and social infrastructure. This includes renewable energy solutions for superior environmental value and efficiency. We give assets a performance advantage and provide better end-user experiences.

Our teams start with the end in mind, connecting clients with advanced expertise across a project’s lifecycle, including design, construction, manufacturing, upgrades and overhauls, asset management and maintenance. For example, on Melbourne Water’s Western Treatment Plant Stage 2, CPB Contractors and UGL are integrating world-class design and construct and expert operations and maintenance capabilities for advanced environmental outcomes.


Our societies live and grow amid a network of infrastructure that keeps us moving, productive, safe, inspired and enabled.

From cutting-edge transport systems to state-of-the-art buildings to industrial operations, the competitive advantage of companies, communities and countries is shaped by their capacity, capability and connectedness. We create infrastructure with future generations in mind.

We place stakeholder needs at the heart of design, construction and commissioning works, and deliver with an operations and maintenance mindset that considers the long-term. For example, on Transport for NSW’s Sydney Metro Northwest Operations, Trains and Systems PPP, CPB Contractors, UGL, Pacific Partnerships and EIC Activities combined their strengths to deliver Australia’s first driverless metro-style rail line through to ongoing operations.


Daily life is powered by the resources sector. It is critical to development and progress. We are committed to supporting Australia’s energy transition, with a focus on large-scale renewable generation assets and the infrastructure required to support it, including storage and transmission assets.

Changes facing the industry include the introduction of advanced technologies such as automation, and advances in environmental sustainability. We unlock resources for maximum productivity and output and work with clients, suppliers and industry to help enable the global energy transition.

Our clients leverage our decades of experience and learnings to fast-track success, across feasibility, planning, operations and maintenance, processing, rehabilitation and decommissioning. For example, on Jellinbah Group’s Lake Vermont, Thiess and Sedgman offer total mining solutions via a world-class operation and state-of-the-art coal handling and preparation plants – building on a long-standing relationship to create new value. 

In renewables, our CIMIC Group company Pacific Partnerships has acquired the development rights for Glenrowan Solar Farm, the first large-scale solar farm to be owned and developed by CIMIC Group as principal. We have a strong history of delivering leading-edge renewable energy projects, such as wind and solar, through CPB Contractors and UGL.
