Temporary works maintain the necessary load path while the permanent structure is changed. Their arrangement, bearing conditions and removal sequence must suit the specific building.
Why the temporary stage is different
A final steel beam drawing describes a completed structure. During removal and installation, the loads may need to travel through a different arrangement. That intermediate stage must be assessed rather than inferred from the finished design.
Look below the supports
A prop transfers load to the surface beneath it. The floor and supporting structure must be capable of receiving the relevant forces. An apparently solid floor finish provides no proof of that capacity; the load path below needs consideration.
Plan and check the arrangement
The engineer and contractor agree the temporary works within their respective scopes. The execution documents should make the sequence and checks clear. Prop numbers, spacing and installation details cannot be taken from the illustrative photographs on this website.
Changes and removal
Unexpected conditions should be reported for assessment before the affected work continues. Temporary support is removed only at the stage permitted by the plan and completed checks. Keep relevant records with the project documents.
Frequently asked questions
Can I use the prop layout in a project photo?
No. A photo shows one moment in another situation and is not a temporary works design for your building.
Does an existing floor automatically support the props?
No. The forces and the construction receiving them must be assessed as part of the temporary load path.
