A wall may support loads, provide fire separation or contain services even when it looks like a simple partition. Determine its role before demolition.
Establish the wall's function
- Check structure above and below, roof loads and any previous alterations.
- Review fire compartments, protected escape routes and sound separation.
- Locate services and obtain suitable asbestos information for the work area.
Plan the work
- Use competent design for support and temporary works where needed.
- Confirm the building control or warrant route and other relevant permissions.
- Arrange safe separation from occupants and realistic access and service interruptions.
Verify completion
- Ensure required inspections occur before the beam or connections are covered.
- Record approved changes and collect completion evidence.
- Check resulting ventilation, finishes and services as well as the structural element.
Give the designer enough information to assess the change
The wall's appearance does not establish whether it supports the building or forms part of a protected escape route.
- Provide a current floor plan, photographs, the proposed opening and any earlier alteration records. Ask for assessment of loads above, hidden services, fire separation and the temporary works needed during construction.
- Confirm who designs the support and who checks installation before it is concealed. Obtain the appropriate approval and consider adjoining-owner requirements with the adviser where relevant.
- Agree safe occupation or temporary arrangements during work. Retain calculations, specifications, inspection evidence and the completion document with the property record.
Example: a partition protects the escape stair
A fictional wall is not load-bearing but encloses a protected stair. Removing it may still create a fire-safety problem. Structural simplicity does not settle whether the alteration is acceptable.
What to do
- Commission the necessary structural and building assessment.
- Confirm approvals, design and contractor responsibilities.
- Inspect and record the completed work before concealment.
Evidence to keep
- Existing layout, survey, calculations and approved details.
- Inspection records, changes and completion documentation.
