Using Revit’s Material List to Calculate Stair Template Area and Concrete Volume
When working with Revit to calculate the area and volume of project components, it’s straightforward for elements like walls, columns, beams, and slabs because these components inherently contain the necessary data. We simply extract and use this information.
However, stairs present a different challenge. Their instance and type properties do not include information about stair area or volume, as illustrated below:
Many users find this confusing and are unsure how to proceed. Fortunately, there is an alternative method: utilizing the material list.
Begin by selecting the staircase in the material extraction dialog box that appears:
Once inside the material extraction properties interface, add four fields: Family and Type, Material: Name, Material: Area, and Material: Volume. These correspond to the detail table’s field columns, as shown in the image below:
After confirming these settings, you will access the staircase material list:
Within the staircase material extraction details table, the Material: Volume represents the component’s volume, which corresponds directly to the concrete volume and can be used as is.
However, the Material: Area refers to the component’s surface area, which is not the actual template area of the staircase. Based on construction practices, we know that apart from the step depth—which does not require formwork installation—all other parts of the stair template generally require formwork.
Therefore, the stair template area can be calculated as follows:
Stair Template Area = Material: Area – Horizontal Projection Area of the Stair Flight
The horizontal projected area of the stair flight is straightforward to obtain, as shown in the figure below:
