rakennetietoja

Rakennetietoja is a Finnish term referring to data and information about the built environment, including individual buildings, structures and related infrastructure. The concept covers design and construction records, current condition, usage and historical renovations, and is used in planning, construction, real estate management and regulatory contexts to describe the physical characteristics and properties of built assets.

Data categories commonly associated with rakennetietoja include location and geometry (maps, footprints, height, number of stories), year of construction, building type and zoning classifications, structural and systems information (mechanical, electrical, plumbing), materials, energy performance and efficiency, accessibility and safety features, as well as maintenance histories, alteration records, construction permits, inspections, warranties, ownership and cadastral identifiers. Sources of rakennetietoja range from municipal building authorities, planning documents and cadastral registers to architectural drawings, BIM models, energy certificates and open data portals.

The information serves multiple purposes. It supports urban planning and development, safety and regulatory compliance, asset management and property valuation, as well as risk assessment and research. In Finland, rakennetietoja are increasingly integrated with geographic information systems (GIS) and building information modeling (BIM) to enable digital twins and more transparent local information services. Challenges include ensuring data quality and interoperability across authorities and private actors, managing privacy and access rights for sensitive data, and aligning different data standards and formats for effective use. The term remains related to, but distinct from, project-specific design data, which may be restricted to authorized parties.
