With the BIMcare™ Real Estate Platform, property owners, investors and operators digitize the entire lifecycle of their real estate assets. At the same time, the platform establishes the foundation for new digital business models and additional revenue streams across the entire building operation. All building, asset and operational information is centrally managed and available in real time at any time. Real estate transforms from a passive asset into an active digital business platform. Digital Business Models The modular architecture provides a flexible entry point based on individual requirements. Owners invest only in the functions and services they actually need. Additional modules such as maintenance, statutory compliance, owner obligations or Facility Management can be activated and expanded digitally at any time. As a result, the platform grows together with the property and can continuously adapt to new requirements, tenants and business models. From Real Estate to a Service Platform The key difference: While traditional real estate models primarily rely on rental income, BIMcare™ creates additional digital revenue streams. This enables predictable cash flows, new business models and long-term scalability across entire real estate portfolios. With the BIMcare™ Real Estate Platform, a property evolves from a traditional investment asset into a digital service platform. Digital services become an integral part of building operations, creating new economic opportunities. Standardized digital management also enables consistent administration and scalable management of real estate portfolios across multiple locations. Benefits for Investors The BIMcare™ Real Estate Platform extends traditional rental income with digital services, creating additional revenue opportunities for property owners, real estate companies and institutional investors. Within Sale-and-Leaseback models or existing real estate portfolios, digital services can be integrated directly into ongoing building operations. This creates recurring revenue streams that extend beyond traditional rental income and support predictable long-term cash flows. Economic Benefits The combination of rental income and digital services generates additional recurring revenue while supporting the long-term stability of a real estate portfolio's cash flows. As a result, owners and investors can not only manage their properties digitally but also establish new digital business models across existing real estate portfolios. Investors benefit not only from predictable rental income but also from a scalable digital business platform that can be deployed across individual buildings as well as entire real estate portfolios. Integrated Services The BIMcare™ Real Estate Platform can be expanded step by step with additional digital services: BIMcare™ Platform License Digital Property and Document Management Digital Building Management Available with additional BIMcare™ packages: Technical Maintenance Contracts Digital Owner Compliance Document and Compliance Management Asset and Facility Management Energy and Sustainability Management Optional Service and Support Modules By combining these services within a lease or service agreement, additional revenue streams are created that increase the economic value of a property while ensuring sustainable digital building operations.
