1. Purpose of the tool.

The Independent Stair Tower is a scaffolding solution designed to provide safe and efficient access in construction environments. Key features include:

• Complementary Functionality: The Independent Stair Tower is introduced to complement the tube and clip scaffold functionality, serving as a common access method in various regions.
• Types of Stairs: It includes options for different stair configurations, such as platform stairs (single and double return) and symmetrical stairs (double return), allowing for flexibility in design.

Design Options: The tool supports the creation of stair towers with double stair flights, enhancing accessibility and safety for workers on site.

2. User Interface overview.

The tool is located under the Scaffold Modelling tab.

To open the tool menu please double click on the tool.
The tool contains following features:

Settings Tab allows users to select a Stair type arrangement that is controlled by the Scaffold System that has been specified in the Project Info Tool.
