With a clear project file, the structural engineer can assess what is needed in a more targeted manner.
Start with the change
Describe the current situation and the desired adjustment separately. A sketch does not have to be beautiful, but it must show where an opening, extension or extra floor will be located. Add photos with a brief explanation of the viewing direction.
Make assumptions visible
Do you not know how the floor is constructed or where the foundation runs? Record that as unknown. A guess can lead to an inappropriate design later. The structural engineer determines what information is still required.
Think beyond construction
Also explain how the space is used. Heavy storage, a bath, installations or future solar panels may be relevant to the design.
Create one overview of your entire renovation
Describe the desired end situation before requesting individual components. A breakthrough, a new bathroom and solar panels seem like three separate wishes, but they can influence the same floor, wall or foundation. Indicate for each procedure what will disappear, what will be added and what use you have in mind. Also mention plans that will only be implemented later. This way, the structural engineer can discuss which parts need to be assessed jointly and which data are missing.
Work with a missing data questionnaire
An incomplete file does not have to stop a first conversation. Make it visible which information is known and which is merely assumed. For example, a photo does not always prove the material or dimensions behind a finish. Note deviations from the archive drawing and ask who will answer them. Then determine what additional pieces are needed, who will collect them, and what design decisions await them.
Avoid planning based on unconfirmed assumptions
A preferred start date is a target until the construction schedule has been agreed. Allow separately for investigation, design, structural detailing, any required procedures and purchasing. Check which activities depend on earlier decisions. Ordering steel before the support details are complete can lead to rework. Agree which documents must be finalised before placing an order or starting a construction stage.
Your preparation in four steps
- Address and type of building
- Description of the desired change
- Existing and new drawings, if available
- Photos and available reports
- Desired planning and contact person
Frequently asked questions on this topic
Can I tell from the thickness whether my wall is load-bearing?
Wall thickness is at most an indication. The load-bearing direction of floors, upper building components, previous renovations and the actual support must be considered together. Collect drawings from multiple floors and determine what additional information is needed. Do not start removal based on a knock test or a comparison with another home.
Is the foundation also examined for a load-bearing wall?
That depends on the agreed assignment and the consequences of the breakthrough. A beam can concentrate forces on smaller support points. The underlying construction and foundation may therefore be relevant. Ask explicitly which supports, columns and existing parts are included, so that it is clear where the assessment ends.
