Structural calculationPrice on requestWhat is assessed?
A chimney can run through multiple floors. If a part remains, it must be clear how it is supported. Adjacent floor and roof components may also be relevant.
Have the existing situation included if drawings are missing or unclear. Make agreements about the sequence and temporary support during implementation.
What data is needed?
The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.
- Cross-section of the chimney flue
- Desired removal per floor
- Photos of all accessible parts
- Adjacent floor data
What do you receive?
Record the exact delivery in the quotation. Depending on your project and assignment, this involves:
- Assessment of remaining construction
- Calculation of possible shelter
- Constructive principles for implementation
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?
Specify exactly which chimney sections will be removed and retained, including on other storeys. A remaining flue or chimney section may need new support. Discuss demolition sequence and temporary support before work starts.
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 |
|---|---|
| Cross-section of the chimney flue | Gather the most recent available data and identify what is missing. |
| Desired removal per floor | Gather the most recent available data and identify what is missing. |
| Photos of all accessible parts | Gather the most recent available data and identify what is missing. |
| Adjacent floor data | Gather the most recent available data and identify what is missing. |
- Describe your complete construction plan.
Investigate what remains above and next to the chimney before parts are removed.
- Discuss missing data.
The structural engineer determines which site survey or additional information is required for the agreed assessment.
- Record order and delivery.
Agree on the calculated parts, drawings, price and planning.
- Coordinate the design with the construction work.
Use the current documents and have relevant changes reviewed before they are implemented.
Frequently asked questions about chimney removal
Can only the bottom part of a chimney be removed?
If parent parts remain in place, it must be clear how they are supported. Adjacent floors and roof parts can also be important. Describe per floor what will disappear and what will be retained and have the relevant construction assessed.
Which photos help with a chimney application?
Send overview images of the floors involved and accessible connections, together with drawings or a section. Make it clear which parts are hidden. The structural engineer determines whether additional research is necessary before a solution can be developed.
