About Oasys

Oasys was born out of the structural engineering expertise and project speed required for the Sydney Opera House. While the construction of the foundations and lower structure continued, the Arup team explored multiple roof schemes, all unbuildable except the last few, which were standardised as segments of the same sphere. The engineers realised that to accurately analyse the roof in the timeframe needed by the contract, they would need to make extensive use of digital computers. To achieve this ‘Arup Computing Group’, in the basement of Arup’s London office, conjured an analytical revolution that has influenced structural engineering as we know it today.

The design and construction marked significant advancements in computational techniques. It was the first major project to use finite element analysis and parametric design. Engineers used early computer models to solve complex structural problems, particularly the geometry of the shells and the glass walls hanging between them. This was crucial in ensuring the timely analysis of the unique roof design.

Three years after the Sydney Opera House opened, the Arup Computing Group started selling their programs globally. Since consulting engineers were not allowed to advertise back then, they sold these programs under the brand Oasys. Today, our development expands far beyond traditional engineering. From cloud-based geotechnical solutions and advanced computational design to 3D pedestrian simulation modelling, our software powers projects across the globe.

At Oasys, our mission is to empower visionary design and innovation in the built environment. We deliver cutting-edge digital solutions that not only meet expectations but consistently exceed them, enhancing productivity, driving profitability, and creating lasting value for our clients. 

We are committed to continuous research and development, ensuring our software remains at the forefront of engineering technology. By fostering a culture of excellence, integrity, and collaboration, we build strong, long-term partnerships with those who share our ambition for better human spaces. 

Our goal is simple yet bold: to be the trusted digital partner of choice for engineers, designers, and planners who shape the future of the built environment.
