Assessment of fire-damaged concrete
After fires, qualified fire assessment are needed to determine the condition of structures and the need for renovation. RISE has competent assessors who can examine concrete structures that have been damaged in fires. RISE has inspected several different fire-damaged structures including garages, residential buildings and industrial facilities.
In general, concrete structures have good resistance to fire. This applies to normal fire temperatures, which are often around 800°C and during exposure times of up to one or two hours. Even in the case of much longer and more severe fires, the concrete frames usually remain in place. However, they may have been damaged in various ways, reducing their load-bearing capacity after the fire.
RISE usually performs visual inspection, damage mapping and removal of drill cores when assessing fire-damaged concrete. Drill cores are then often used for further analysis in RISE's laboratory. This methodology allows for a more detailed assessment of the extent and nature of the damage and helps to understand the performance of the concrete after the fire.
RISE fire assessments are usually compiled in verified survey reports with condition assessment and renovation proposals.
