Concurrent engineering
Chaos systems AB works as project leaders in concurrent engineering and we help you to handle all your data in all large construction projects.
We develop our own software system: the survey, mapping and design system Topocad and its modules, and the document and drawing management system Chaos desktop and Chaos server.
We work as consultancies within project- and document management, but also undertake assignments as calculation assignment within CAD and surveying. We have a very long experience of concurrent engineering.

At present we work with mainly computer coordination on several larger construction projects, for example Northern link, Citybanan and Ostlänken. We gladly take this kind of assignments and we also deal with the making of CAD-manuals, and give reviews and courses in project management.
