Foundations · calculationFrom €869.99 incl. VAT€719.00 excl. VATWhat is assessed?
The foundation distributes the forces from the building over the load-bearing soil or foundation piles. The choice follows from the loads, soil structure and allowable deformations. The dimensions of the building alone are insufficient for this.
In existing construction, settlements, existing pile data and the connection to new components play a role. Available soil research is included; missing information may require additional research.
What data is needed?
The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.
- Loads and design of the superstructure
- Available soundings or soil reports
- Existing foundation drawings
- Data about adjacencies
What do you receive?
Record the exact delivery in the quotation. Depending on your project and assignment, this involves:
- Foundation calculation within the assignment
- Dimensions and material data
- Structural drawings and reinforcement where agreed
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 Concrete and reinforcement 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 foundation calculation needs building loads and suitable ground information. Ask which cone penetration tests, archive records or inspections are missing and who arranges them. Investigation, design and construction are separate parts of the overall project cost.
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 |
|---|---|
| Loads and design of the superstructure | Gather the most recent available data and identify what is missing. |
| Available soundings or soil reports | Gather the most recent available data and identify what is missing. |
| Existing foundation drawings | Gather the most recent available data and identify what is missing. |
| Data about adjacencies | Gather the most recent available data and identify what is missing. |
- Describe your complete construction plan.
A substructure that matches the building and the soil. For new construction, expansion and structural adjustments.
- 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 foundations
Is a CPT the same as foundation advice?
No. A CPT is a measurement of the properties of the subsurface. An advice connects soil data with the design question and building loads. Ask what studies are available and whether they are sufficiently appropriate for the location and the proposed structure.
Can an existing foundation be reused?
This requires an assessment of the existing foundation, its condition and the new load. Available drawings, pile data, soil surveys and previous reports can help. The mere fact that a building has been there for a long time does not provide an answer to a new structural change.
Is reinforcement indicated in the foundation calculation?
Which reinforcement drawings or details you receive depends on the design and the assignment. Record which foundation components are calculated and how the calculation is delivered. Coordinate supplier information and any implementation questions with the party that designs the relevant parts.
Why are the adjacent buildings relevant?
Construction, excavation or changes in the subsurface can affect adjacent areas. The data and research required depends on the situation. Indicate the distance to other buildings and share known information about existing foundations, basements and damage.
