From O-Prognose to Spacewell Maintenance Planning
The trusted foundation of Plandatis, now part of Spacewell

Founded in 1989 in the Netherlands, Plandatis became a pioneer in long-term maintenance planning software.
Its flagship product, O-Prognose, set the standard for reliable, data-driven maintenance forecasts—empowering thousands of organizations to plan budgets, stay compliant, and extend the lifetime of their buildings with confidence.
Over the decades, O-Prognose grew from a specialist tool into a trusted partner for both public and private sector organizations, from housing associations to universities and municipalities. O-Prognose has always been unique in its approach: translating technical building data into clear, actionable insights that bridge the gap between engineers, financial controllers, and policymakers.
In 2019, Plandatis joined Spacewell, part of the Nemetschek Group, one of Europe’s leading software companies for the built environment. This marked the beginning of a new chapter—combining Plandatis’ deep domain expertise with Spacewell’s broader ecosystem for Asset, Workplace, and Energy Management. Together, we continue the same mission that started more than 30 years ago: helping organizations make buildings work better, for people and for the planet..
The Plandatis team is now fully part of Spacewell. Solutions remain, supported by the same people. Gain broader innovation, impactful features, and stronger support.
