When is a structural calculation needed for a padel court?

A structural calculation for a padel court is mandatory as soon as you need an environmental permit, which is the case for almost every outdoor padel court. For indoor installation in an existing hall, it depends on the situation.

The calculation is the technical proof that the structure is safe under the loads that occur at the location, including wind load, the weight of the glass and lighting, and any additional features. In this article we answer the most frequently asked questions about structural calculations, from the situations in which they are mandatory to the duration of the permit procedure.

Which circumstances make a structural calculation mandatory?

A structural calculation is mandatory as soon as a padel court is classed as a structure under planning and building regulations. For outdoor padel courts this is almost always the case. The municipality requests the calculation as part of the environmental permit application, so that structural safety can be checked before the court is built.

In practice, there are four situations in which a structural calculation is always needed:

• When building a new outdoor padel court, regardless of the location.
• When expanding an existing sports park with additional courts.
• When adding features that increase the load on the structure, such as sound-absorbing panels or a noise barrier.
• At locations with special conditions, such as open terrain with high wind loads or a site close to buildings.

The calculation shows that the structure and wind load have been correctly taken into account in the design. Without this justification, the municipality usually does not accept the permit application.

For indoor installation in an existing hall without structural changes to the building, a separate building permit is not always required. Even then it is wise to have a structural calculation made, because the cage transfers loads to the floor that the existing hall must be able to bear.

How does wind load affect the structural calculation of a padel court?

Wind load is one of the decisive factors in the structural calculation of an outdoor padel court. A padel cage is a relatively open structure, but the glass and fencing catch wind. The resulting forces must be transferred through the steel structure to the foundation. How large those forces are depends on the location and its surroundings.

The wind load is determined by the wind zone in which the location lies. The Netherlands has several wind zones, with coastal locations and open polder areas facing higher wind loads than urban locations or sites sheltered behind buildings. A padel court on an open sports park on the edge of a town therefore needs a heavier calculation than a court on a sheltered inner site.

The calculation goes beyond the wind force itself. The height of the structure, the dimensions of the glass surface, the connections between the steel sections and the anchoring in the foundation are also calculated. A padel court including groundwork is a coherent system in which the foundation must ultimately be able to transfer the wind forces into the ground.

Because we produce the steel structure ourselves, we can adapt the section sizes and connection details to the specific wind load of a location. That is a fundamental difference from an imported standard court, where the structure is not calculated per location.

What changes in the calculation when sound-absorbing panels are added?

Adding sound-absorbing panels to a padel cage has direct consequences for the structural calculation. Panels reduce the wind permeability of the cage, which increases the wind load on the structure. The steel structure must be calculated for this and, in many cases, strengthened before panels can be fixed safely.

This applies to new courts as well as existing cages. With an existing court, it cannot be taken for granted that the structure can handle the extra load. A structural engineer must assess the situation before panels are installed. In that case, panels cannot simply be added afterwards.

Strengthening the structure can involve heavier posts, additional columns or adapted connection details. Which changes are needed depends on the position of the panels, the number of sides fitted with panels and the wind load at the location.

In our engineering, the extra load caused by sound-absorbing panels is taken into account from the design phase. This way, acoustic solutions for padel are integrated into the overall design in a structurally sound way, instead of being fixed afterwards to a structure that was not designed for them.

Who may carry out a structural calculation for a padel court?

A structural calculation for a padel court must be prepared by a certified structural engineer or engineering firm. This is someone with the right training and qualifications to make structural calculations that comply with the applicable standards, including the Eurocodes that apply in the Netherlands to steel structures and wind loads.

The municipality checks the calculations submitted with the permit application. A calculation that was not prepared by a qualified party or does not meet the applicable standards will not be accepted. This can delay the permit procedure.

In practice, padel builders, manufacturers and acoustic consultants work with external structural engineers who prepare the calculations. As the manufacturer, we supply the technical data of the steel structure, such as section dimensions, material specifications and connection details, so that the structural engineer can carry out the calculation correctly.

It is wise to involve the structural engineer early in the project, especially when the location has special conditions or when sound-absorbing panels or a noise barrier are part of the design.

Is a structural calculation also needed for an indoor padel court?

For an indoor padel court in an existing hall, a structural calculation is not always legally required. Whether a permit is needed depends on the municipality and the specific situation. Even so, a structural calculation is often wise for indoor installation too, because the cage transfers forces to the floor and in some cases to the hall itself.

When the hall is structurally modified, for example by adding fixing points in the floor or anchors in the concrete slab, a structural assessment is always needed. The owner of the hall or building will want to know whether the floor can bear the load.

Wind load plays no role for indoor courts, but the cage must still meet the requirements for structural safety. Think of the load of the glass, the LED lighting and the connections between the steel sections. Having a padel court built in an existing hall therefore always calls for a technical assessment of the location, even if a formal permit is not required.

What does a structural calculation for a padel court cost?

The cost of a structural calculation for a padel court varies and depends on the complexity of the project, the location and the engineering firm that prepares it. A simple calculation for a standard indoor court takes less work than one for an outdoor court with sound-absorbing panels at a location with high wind loads.

As a guide, structural calculations for padel courts are in practice included as part of the total project costs. In a turnkey project, the costs of engineering and calculations are usually included in the overall price. In a project where the client handles the permit application, the structural engineer’s costs are charged separately.

It is not wise to economise on the structural calculation. An incomplete or incorrect calculation delays the permit procedure and, in the worst case, can mean that the structure has to be modified after the court has already been installed. A clear view of the total costs of a padel court helps you set a realistic budget, including the additional costs of engineering and permits.

What does the process from structural calculation to permit look like?

The process from structural calculation to permit usually follows a fixed order. The structural calculation is one of the documents submitted with the environmental permit application. Without it, the application is incomplete and will not be processed.

A typical process looks like this:

1. Site analysis: the location is assessed for available space, soil conditions, distance to homes and wind load.
2. Design and engineering: the structure is designed based on the site data. Any sound-absorbing panels or other additional features are included in the design.
3. Structural calculation: a certified structural engineer prepares the calculation in line with the applicable standards.
4. Acoustic study (if applicable): at locations near homes or other noise-sensitive sites, an independent acoustic consultant carries out a study. This study is a separate part of the permit application.
5. Permit application: all documents are submitted to the municipality. Processing takes 8 to 12 weeks on average, depending on the municipality and the complexity of the project.
6. Permit granted: once approved, construction can begin.

The municipality may request additional information during processing, such as a lighting study, a site plan or in some cases an ecological survey. It is wise to contact the municipality informally before applying to find out which documents are expected.

We can guide and coordinate the permit procedure, including liaising with structural engineers and acoustic consultants. Read more about applying for a permit for a padel court on our permit page.
