Is a construction calculation required for building a foundation?
When building a foundation, you place the base of the supporting structure of your home or building. If the foundation is constructed incorrectly, you run the risk of the structure sagging, cracking or worse.
To prevent these types of dangerous situations, the government has environmental law decision It is established that you must always be able to demonstrate that your foundation is safe, this also applies if you are allowed to build without a permit. A construction calculation of your foundation ensures this. If an environmental permit is required for your foundation, the construction calculation is part of the permit application and is therefore essential for approval. Can you build without a permit? Then you are responsible for complying with the safety rules.
What is calculated in a foundation construction calculation?
When making a construction calculation for a foundation, it must first be determined whether it must be built on steel or whether a pile foundation is required.
Foundation on steel
Steel foundations are a foundation method in which the walls rest directly on the load-bearing soil, usually through a wider base. For a steel foundation, the constructor calculates the width, thickness and required reinforcement for the strips or foundation plate.
Foundation on piles
A pile foundation is a foundation in which the own weight of the structure and the forces acting on it are transferred to the load-bearing surface via driven piles or piles. The piles must have a length of at least 5 times the cross-section. With a foundation on piles, a constructor calculates, among other things, the position of the piles, the depth of the piles and the type of pile that must be driven into the ground.
Foundation on piles or a foundation on steel?
The type of foundation you need to build depends, among other things, on where you live. Is there a sand layer about 2 meters below ground level? A steel foundation is often chosen. If the sand layer is deeper than 3 meters, a foundation on piles is calculated.
After making the construction calculation, the constructor processes the calculated result on the construction drawing. Thanks to this construction drawing, the contractor has insight into which building materials are needed and how he should install the construction. You can see this construction drawing as a manual for the contractor.
When making a construction calculation of a foundation, it is important to know that this is always combined with the construction calculation of the entire structure. The constructor knows how strong the foundation must be if it is known what is being built on the foundation. Therefore, in addition to the foundation calculation, the constructor also calculates the following parts of the construction in this process:
- Beam layers
- Roof construction
- Beams and columns
- Floor construction

Frequently asked questions about making construction calculations
What does a structural engineer do?
A structural engineer tests and calculates structures of buildings through structural analysis. Think of bridges, homes, commercial buildings and other types of structures. It is the task of the structural engineer to make a calculation that ensures that the renovation can be carried out safely and efficiently by the contractor.
When do you need a structural calculation?
When you change anything in your home to the existing load-bearing parts, you need a structural analysis. Examples of these parts include; floors, beams, roofs, foundations and walls.
A structural calculation is also required for new buildings to ensure that the construction is safe. Examples of this include; extension, dormer or extension.
This involves making sure your idea is strong enough that it doesn’t end up sagging or worse.
What is the cost of a structural calculation?
The cost of a construction calculation depends on the type of construction and its size. You can contact us for a quote request for your construction.
How long is the delivery time of a construction calculation?
The delivery time of your construction is 5 working days after approval of the given quotation. If there is more urgency you can contact us for the possibilities. We like to think along with you.
Do your structural engineers work throughout the Netherlands?
Our structural engineers work for part of the Netherlands. In most cases we make the structural calculations remotely. If a site visit is still required, we will of course arrange that as well.
What does the structural engineer need for a structural calculation?
Our structural engineers make the structural calculation based on two types of construction drawings. These are the original drawings of the building, which can be requested from the municipal archives. In addition, the structural engineers also need a drawing of the desired situation.
How does the structural engineer make the structural calculation?
So the structural engineer uses two types of building plans to make the calculation. He ensures that all possible loads have been calculated so that no cracks or deflections can occur. In doing so, the structural engineer also takes into account the necessary regulations.
How do I request the structural calculation?
You now know all about the calculation. The last question is how to request a structural calculation. This is actually very simple, you can do this with us! Request a free quote on our quote page.
What information does the structural engineer need for the calculation?
What information does the structural engineer need for the calculation?
Before one of our constructors can make a construction calculation of your foundation, he needs two types of drawings and the following information
- Original drawings of the building
- Drawing of the desired situation
- The ground data
Original drawings of the building
All these drawings are stored in the municipal archives. Here the construction drawings are especially important for the constructor. You can request these construction drawings, even if you are not yet the owner of the property. Would you rather have us request the original drawings for you? That is also possible, more information can be found in our quotation.
Drawing of the desired situation
Furthermore, a constructor needs information about the desired situation. A construction drawing of the desired situation makes it clear what your wishes are as a customer. Based on a construction drawing of the desired situation, it becomes clear to the constructor what all the wishes are. The constructor uses the customer’s input to design the foundation.
Land data
In many cases you will also find information about the land in the municipal archives. If this information is not available, we recommend that you contact us. We will search for the necessary data in our database. If this data is not available, new soundings must be made.
Placing a foundation and applying for a permit?
Does the foundation not fall under the permit-free conditions? Then you must apply for an environmental permit for your foundation via the environmental counter. For the permit you need a construction drawing and a construction calculation of the foundation. Based on these drawings, the municipality checks whether you meet the requirements of the building code, the zoning plan and the building regulations.
Please note: the municipality has 8 weeks to issue the permit. Therefore, make sure that you apply for the permit on time.
To help you apply for the permit, we have created a blog showing the steps you need to take to easily apply for your own permit. Not quite sure? Then you can always contact us. We will then schedule a team meeting and one of our designers will help you with your request.
