During a renovation, the temporary situation may have different points of interest than the end result.
The construction phase requires its own assessment
When a load-bearing part is removed, the new construction is often not yet active. The load must be collected via a different route in that phase.
What is being coordinated?
The parties involved record which temporary facilities are needed, where they are supported and what order is used. The underlying floors and the available space are also part of the assessment.
Agree on the assignment clearly
A calculation for the final one beam does not automatically include the temporary support plan. Discuss in advance who will develop this and how changes will be coordinated with construction.
Construction phase and final state are different situations
During demolition and assembly, parts that are correct in the final condition are sometimes missing stability or provide support. The temporary load route may therefore be different. One temporary propping plan or other temporary effect must match the actual chosen version. This includes support, payment, surface and the times at which parts are removed or installed. General assembly photos are no substitute for this.
Determine information and responsibility in advance
When placing the order, ask who designs the temporary support, who coordinates the implementation and what control has been agreed. The operator must share relevant information about accessibility, work order and equipment in a timely manner. If the situation encountered differs, the effect must be assessed. Keep the current documents with the implementation documents and ensure that everyone involved knows which version applies to their work.
Your preparation in four steps
- Discuss temporary support as a separate topic
- Have the substrate and underlying floors assessed
- Determine the order of execution
- Designate person responsible for adjustments
Frequently asked questions on this topic
Can I tell from the thickness whether my wall is load-bearing?
Wall thickness is at most an indication. The load-bearing direction of floors, upper building components, previous renovations and the actual support must be considered together. Collect drawings from multiple floors and determine what additional information is needed. Do not start removal based on a knock test or a comparison with another home.
Is the foundation also examined for a load-bearing wall?
That depends on the agreed assignment and the consequences of the breakthrough. A beam can concentrate forces on smaller support points. The underlying construction and foundation may therefore be relevant. Ask explicitly which supports, columns and existing parts are included, so that it is clear where the assessment ends.
