Structural calculations for a steel structure

What does this project require structurally?

A steel structure is more than a collection of sections. Connections, lateral restraint, stability and interfaces also determine its performance. A steel fabricator's production and erection drawings are a separate task that must be agreed in advance.

Which information helps with your enquiry?

• Design showing supports
• Loads and use
• Available structural depth
• Connections to concrete, timber or masonry

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?

• Calculations for the agreed steel elements
• Design basis for connections
• Structural drawing as set out in the quotation

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.
