Structural calculations for foundations

What does this project require structurally?

The choice between shallow foundations and piles depends on loads, ground information and surroundings. A place name or a neighbour's foundations cannot replace project-specific information. Settlement and connections to existing buildings need particular attention.

Which information helps with your enquiry?

• Building proposal with loads and dimensions
• Cone penetration test or other suitable ground investigation
• Existing foundation information
• Information about adjoining buildings

You do not need to have everything ready. State which documents are available and what is still unknown. We first assess whether there is enough information to define the brief. A site survey or further investigation may be necessary.

What can your brief include?

• Foundation design within the agreed scope
• Calculations for load-bearing foundation elements
• Concept and dimensions in the final project documents

The quotation records which elements will be calculated and drawn, the information used as a starting point and when the documents will be delivered. This makes the scope clear to you, your adviser and your contractor.

What is not automatically included?

Architectural drawings, ground investigations, archive research, site visits, supplier calculations, temporary support and construction supervision are included only when explicitly agreed. Materials and construction work are outside the calculation fee.

Permits and structural assessment

Check the procedure for your activity and location through the Dutch Omgevingsloket. A structural report substantiates the agreed elements; it does not determine whether the entire building proposal is permitted.

From information to final project documents

Once your enquiry is agreed, the design basis is recorded, calculations and drawings are prepared and internally checked. Your contractor receives the final documents with a revision reference. Any discrepancy in the existing situation or change to your plans must be reported before work on the affected element continues.
