Garage structural calculation

A supporting structure that suits a large door opening and the intended use.

Two construction professionals discuss a drawing at a construction siteStructural calculationPrice on request
The final price and included work will be recorded in your quotation.

What is assessed?

The garage door interrupts a large part of the facade. The remaining walls and any portal construction must support the roof and provide stability.

Make it clear whether the roof will be accessible and whether there will be storage or an upper floor. A later change may require a new assessment.

What data is needed?

The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.

  • Floor plan and doors
  • Roof and floor build-up
  • Use of the garage
  • Foundation information

What do you receive?

Record the exact delivery in the quotation. Depending on your project and assignment, this involves:

  • Calculation of the main structure
  • Accommodation of openings
  • Foundation design assumptions
The connection makes the difference.

Discuss who will take care of the architectural development, supplier details and any temporary support. In this way, the components involved are coordinated.

Materials and drawings

The choice of materials and connections follow from the design. Read more about Masonry and sand-lime brick and the difference between a architectural drawing and a construction drawing.

How does the process proceed?

You describe your project and share the available data. The assignment, any additional information and planning are then coordinated. Check it out complete step-by-step plan for all phases.

What does your assignment cover?

A wide garage door leaves less solid wall for stability. Show the roof span and wall layout as well as the door opening. Mention loft storage or a future upper storey in advance; these uses must not be assumed.

Can I already order material?

Order structural parts based on the coordinated and current design data. A preliminary estimate is not a complete basis for this.

Is a site visit necessary?

That depends on the project and the available information. Sometimes drawings and photos are sufficient for the inventory; sometimes an admission or additional examination is necessary.

What happens if my plan changes?

Report changes before they are implemented. The structural engineer assesses whether calculations and drawings need to be adjusted.

Frequently asked questions about garage

Why is a wide garage door constructively relevant?

The opening takes away a large part of the facade. The structure above and next to the opening must be able to absorb and dissipate the associated forces. The roof structure and stability design partly determine the solution.

Does storage above the garage make a difference?

Yes, the use and planned storage influence the principles for a first floor and the substructure. Please specify the intended use and have changes compared to the original design assessed.
