Founded by Sir Ove Arup in 1946, we are an independent, employee-owned firm with over 17,000 people working across more than 90 offices in 35 countries. From the Sydney Opera House to cutting-edge net-zero buildings, our work spans every aspect of the built and natural environment. Our ownership structure — held in trust for the benefit of current and former employees — ensures that we remain true to our founding principles: to do socially useful work, pursue excellence, and share our success. We operate without the pressures of external shareholders, allowing us to focus on what matters most: delivering outstanding outcomes for our clients and for the world.

We are economists, engineers, architects, planners, management consultants, sustainability experts, digital specialists, and more — working as one joined-up team. Our 'borderless' culture means a structural engineer in Auckland collaborates with a digital expert in London on the same data centre project. We attract naturally collaborative people who want to solve complex problems and create a better world. Our strength comes from how we respect, share, and connect our diverse experiences, perspectives, and ideas across 140 countries.

We provide technical, engineering, climate, and advisory services that address every priority in the built and natural environments. Our advisory teams help clients solve business and operational challenges, make informed commercial decisions, and implement more sustainable solutions. We combine deep sector knowledge with management consulting, financial advisory, strategy, operations expertise, climate science, and digital innovation — delivering integrated insight that other consultants simply cannot match. Whether advising on infrastructure investment strategy, decarbonisation, programme delivery, or asset management, we add value at every stage of a project's lifecycle.

Our purpose is to shape a better world. Everything we do is guided by our commitment to sustainable development — designing and advising in ways that are technically excellent, socially responsible, and environmentally sound. We believe that the built environment is one of the greatest levers for positive change, and we bring our full breadth of expertise to bear in pursuit of outcomes that matter: resilient cities, clean energy systems, equitable communities, and a net-zero future.

Arup is guided by the principles set out by our founder: to do work of quality, to be humane, and to act with integrity. As an employee-owned firm, our profits are shared with our people — reinforcing a culture where excellence and ethics go hand in hand. We champion equity, diversity, and inclusion; we invest in the wellbeing and development of every member; and we hold ourselves accountable through our annual ESG report. These are not aspirations — they are embedded in how we work every day.

What sets us apart is our ability to bring together technical, advisory, and management expertise in one joined-up team. Our advisory clients gain access to the same deep engineering and sustainability knowledge that underpins our design and infrastructure work — insight that specialist management consultancies simply cannot provide. Our independence means our advice is always in our clients' interests. And our global network, with projects in over 160 countries, means we bring truly international perspective to every challenge.

Sustainability is not a service line at Arup — it is the foundation of everything we do. We publish an Annual ESG Report, hold ourselves to ambitious net-zero commitments, and embed climate, nature, and environment considerations across all our projects and corporate practices. Our global Community Engagement function supports the most marginalised in society. We help clients decarbonise, build climate resilience, invest sustainably, and transition to circular economy models — while applying the same standards internally.

Arup supports communities worldwide through pro bono services, operated through our global Community Engagement function. We assist the most marginalised in society, providing engineering, advisory, and design expertise to projects and organisations that could not otherwise access it. Our teams engage local residents across infrastructure projects — co-designing active neighbourhood schemes, running public consultations, and using virtual reality tools to broaden participation and improve the quality of community feedback.

We believe there is nothing we cannot achieve when we work together. Our Equity, Diversity, and Inclusion Policy commits us to promoting belonging across the firm — respecting, sharing, and connecting diverse experiences, perspectives, and ideas. We encourage individuality to thrive, and we care about each member's success so we can grow together. Health, Safety, and Wellbeing is also a core Group Policy, ensuring that every member works in an environment that supports them physically and mentally.
