Move your building plans forward.
You do not need every answer before getting in touch. Start with a short description of your project and the information you already have.
Tell us what you want to change
Describe your plans and the location. Add any drawings and photos you have, and let us know what is still missing.
Clarify the scope of your project
We review your enquiry and discuss any further information needed. The quote sets out the work, price and schedule.
Have your plans developed
After approval, the agreed structural calculations are prepared. Drawings and coordination are included as specified in your commission.
Prepare for construction
You receive the agreed documents. Let us know if your plans change so that any necessary revisions can be assessed.
What you can send to get started
- A short description of the existing and proposed situation.
- Available drawings and photographs of the relevant parts of the building.
- The project location, your questions and any preferred schedule.
Some information still missing? Tell us what you have. Your enquiry can be the start of the conversation.
Do you have a preferred date?
Include it in your enquiry. The achievable schedule depends on the work, availability and information required. Any urgent deadline or surcharge must be agreed for your project in advance.
Have your plans changed?
Tell us before the changes are carried out. Their impact on the calculations, drawings and agreed scope can then be assessed.
Questions and comments about your report
Have a question from the municipality or your contractor, or a comment on your calculations? Share the project address, current documents and the complete question.
What should I do with a question from the municipality or contractor?
Send the complete question and the relevant calculation or drawing. We review what it means for your report and discuss whether an addition or amendment to your report is needed and whether it falls within the agreed scope of work.
I suspect an error in my calculations. What should I do?
Identify the page, drawing or result you would like checked, together with the project address and document version. This helps us investigate your question. The existing arrangements for corrections are on our Payments and guarantee page, in Dutch.
