The Milan property management company CB Amministrazioni has published technical information on intermediate floor beams in modern residential buildings. The material is aimed at owners and tenants planning renovation work. The focus is on the question of when load-bearing beams can be damaged during interventions and who is liable in case of damage. The initiative shows: Many property managers have so far provided insufficient information about structural risks – owners are often liable for improper work themselves, even if the management has provided no technical clarification.
