How to Calculate Spiral Staircase Dimensions and Designs

Spiral staircases save valuable square meters because they occupy a much smaller area than a conventional staircase. With daring shapes and diverse configurations, they can also be iconic objects in projects. However, the design of these staircases requires careful attention so that you can prevent an uncomfortable or dangerous outcome. Although BIM software simplifies this process, it’s always important to understand the restrictions and the underlying concepts.
