EL-025 / FIRE DETECTION / LOAD-BEARING STRUCTURE
PRIORITY / MAJOR
OBSERVED
A through-chase has been cut into a load-bearing reinforced concrete beam to route a fire alarm cable line.
RISK
An intervention has been made in a load-bearing structure without confirmation that the solution is acceptable. The possible effect of the opening/chase on the structure requires assessment.
WHAT TO CHECK
The working and structural documentation, actual location and dimensions of the opening/chase, and availability of an agreed cable penetration solution for the load-bearing structure. Obtain a structural engineer’s opinion where necessary.
RECOMMENDED ACTION
Do not undertake further work that conceals this area until the penetration has been examined and an agreed technical solution has been obtained from the responsible designer/structural engineer.
