rakennekartoitukset

Rakennekartoitukset, or building surveys, are systematic assessments of a building’s structural and architectural conditions. They involve detailed inspections of foundations, load‑bearing walls, roofs, and service systems such as plumbing, heating, and electrical networks. The aim is to identify existing defects, potential risks, and opportunities for improvement or rehabilitation. Rakennekartoitukset are commonly carried out by certified surveyors or architects and form the technical basis for maintenance planning, renovation proposals, or legal compliance.

The process typically starts with a visual inspection of the exterior and interior, followed by non‑destructive testing methods such as ultrasonic probing, infrared thermography, and electrical conductivity surveys. In many cases, material sampling is performed to analyze concrete strength or wood decay. The surveyors compile a report that includes photographs, measurements, defect descriptions, risk assessments, and cost estimates for remedial work. In Finland, building surveys are often required by municipal safety authorities when a property is to be sold, transferred, or when substantial works are planned, ensuring that owners are aware of structural integrity issues and that future occupants are protected.

Rakennekartoitukset play a key role in preserving historic buildings. They provide a documented record of a structure’s original state and any subsequent alterations, enabling sensitive restoration that complies with heritage conservation guidelines. In the private sector, detailed surveys can justify investment in energy‑efficient renovations or inform insurance underwriting. Because building regulations in Finland continuously evolve, periodic revisits of old surveys are valuable for maintaining compliance and safeguarding long‑term property value.
