Load-bearing wall · calculationFrom €506.99 incl. VAT€419.00 excl. VATWhat is assessed?
The most important question is what the wall supports: a floor, the roof, upper walls or a combination. The structural engineer examines the loads and the route by which they are transported to the foundation.
A beam alone is not always sufficient. The supports, any columns and the existing foundation must also be able to absorb the new forces.
What data is needed?
The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.
- Floor plans of all floors
- Desired width and position of the opening
- Photos of the wall, floor and upper situation
- Available archive and construction drawings
What do you receive?
Record the exact delivery in the quotation. Depending on your project and assignment, this involves:
- Calculation of the replacement supporting structure
- Overview of beam, possible columns and supports
- Required connection details within the agreed assignment
Discuss who will take care of the architectural development, supplier details and any temporary support. In this way, the components involved are coordinated.
Materials and drawings
The choice of materials and connections follow from the design. Read more about Steel and the difference between a architectural drawing and a construction drawing.
How does the process proceed?
You describe your project and share the available data. The assignment, any additional information and planning are then coordinated. Check it out complete step-by-step plan for all phases.
What does your assignment cover?
A wall opening requires more than a beam size. Ask whether the quotation covers bearings, any columns and the structure below. Before demolition, agree who designs the temporary propping; temporary support needs its own assessment.
Can I already order material?
Order structural parts based on the coordinated and current design data. A preliminary estimate is not a complete basis for this.
Is a site visit necessary?
That depends on the project and the available information. Sometimes drawings and photos are sufficient for the inventory; sometimes an admission or additional examination is necessary.
What happens if my plan changes?
Report changes before they are implemented. The structural engineer assesses whether calculations and drawings need to be adjusted.
From data to a detailed plan
Checklist for your application
| Given | What you prepare |
|---|---|
| Floor plans of all floors | Gather the most recent available data and identify what is missing. |
| Desired width and position of the opening | Gather the most recent available data and identify what is missing. |
| Photos of the wall, floor and upper situation | Gather the most recent available data and identify what is missing. |
| Available archive and construction drawings | Gather the most recent available data and identify what is missing. |
- Describe your complete construction plan.
Make room for an open layout. First determine how the load on the existing wall will be absorbed.
- Discuss missing data.
The structural engineer determines which recording or additional information is required for the agreed assessment.
- Record order and delivery.
Agree on the calculated parts, drawings, price and planning.
- Match the effect to the implementation.
Use the current documents and have relevant changes reviewed before they are implemented.
Frequently asked questions about removing a load-bearing wall
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.
What is included in the starting price for a load-bearing wall calculation?
De gepubliceerde vanafprijs is €419. The quotation must state which parts and drawings can be developed for this in your situation. Demolition, steel, assembly, finishing and temporary support are not automatically part of the calculation order. The VAT status of the published starting price is yet to be confirmed.
Can the beam disappear completely into the ceiling?
That is a design question related to floor structure, available height, loads and connections. Please indicate the desired finish when requesting. Have possible solutions agreed upon by the designer and structural engineer before the ceiling height, installations and steel order are finalized.
