Software products

We develop software to match the exacting demands of the world’s leading designers.

Arup began developing its own software more than 40 years ago in response to our evolving challenges. Today, our software house Oasys brings relevant, flexible tools to organisations worldwide.

Oasys Ltd leads the field in structural, geotechnical, crowd simulation and document management solutions. Its programs are used across 200 countries, by leading designers, planners, engineers and architects and by numerous universities across the globe.

Powerful tools

For the analysis behind high-performance structures, designers depend on sophisticated, customisable tools. They also need to communicate complex information to clients, collaborators and stakeholders through accessible but compelling visualisations.

Oasys’ structural software programs answer these demands. They support the design process from the initial concept to the finest detail, from tall buildings and rail bridges to the analysis and design of columns and beams and sections under load.

Programs such as GSA have helped engineers to realise landmark projects worldwide, from the Beijing National Aquatics Center (Water Cube) to the CCTV Building, China. GSA’s advanced features such as footfall analysis, form finding and fabric analysis makes this a comprehensive design and analysis tool for any structure.

Oasys’ geotechnical software solutions provide engineers with the tools to tackle the most complex of projects, whether that be for retaining walls, slope stability analysis, piling & foundations or tunnelling, excavations and ground movement. Oasys software has been instrumental when tackling some of the world’s most complicated geotechnical issues, providing a safe and effective solution for projects such as Crossrail, The Pinnacle and the Emirates Pearl tower, Abu Dhabi.

Crowd Simulation

With the increasing importance of BIM, Oasys’ pedestrian and crowd simulation tools make designs safer and more efficient. Predict how pedestrians will interact within any environment, which includes rail stations, airport terminals, stadiums, office buildings, shopping plazas and urban design.

MassMotion and Flow are also instrumental when looking at evacuation procedures, testing building performance and showing these results in a range of graphical and tabular outputs.

Email and document management

Oasys’ email and document management software helps organisations, from accountants to local governments, to become better organised and share electronic information. Mail Manager helps organisations of any size improve efficiency, communication and collaboration by ensuring their employees can file, find and share emails with ease.

    Your best solution to date?

    Mail Manager stands out at the time of writing.

    Why is it significant?

    We worked hard to make it easy for users to file messages while they work so that it's not a task to do later, and created a fast search tool so that they could find what they had filed quickly and easily. It has become extremely successful largely because it saves people time, frustration and sometimes their skin.

    Your particular skill?

    Listening. Whilst a varied background does help, which in my case covers product design and manufacture, architecture, CAD, systems management, business management and sales, to develop good software you need to be able listen.


    Technology of all kinds.

    Why Arup?

    When I joined Arup I was told that as long as I didn't lose money or damage the firm's reputation I could pretty much do what I wanted. Whilst this has to be taken in context, it has proved to be true and Arup still attracts talented people and gives them space to grow.
