EL-024 / CABLE LINES / FLOOR SLAB

PRIORITY / MAJOR

OBSERVED

A chase has been cut into a hollow-core floor slab to install a cable line.

RISK

Intervention in the floor slab without a confirmed design solution may affect its structural characteristics.

WHAT TO CHECK

The working documentation, location and depth of the chase, slab construction, and acceptability of this cable routing method. Obtain a structural engineer’s assessment where necessary.

RECOMMENDED ACTION

Before continuing work in this area, verify the acceptability of the chase against the design and structural documentation. If no solution is specified, agree further action with the designer/structural engineer.

PRIORITY / MAJOR

Priority reflects an engineering assessment of the recorded condition in the circumstances of the particular project. It does not replace a designer’s opinion, testing or measurements where these are required.

These examples show the format of engineering records. The final assessment takes into account the design documentation, design solutions and conditions of the specific project.
