Place the floor modification and the delivery of the stairs side by side.

Two parts that connect together
The structural engineer assesses the opening and containment structure. The staircase supplier designs the stairs and connections. The contractor takes care of the agreed implementation.
Make the boundaries clear
Ask which party will make the opening, repair the finish and provide any temporary facilities. Check that the final sizing has been communicated to all involved.
The floor type partly determines the information need
A wooden one beam layer, solid concrete floor and prefabricated floor system do not require the same approach. The location of the opening in relation to beams, ribs or other components is relevant. Collect available drawings and supplier information of the floor. Have the desired stairs and free height worked out in a timely manner, so that the constructive assessment is related to a concrete opening.
Separate calculation, stairs and execution in your budget
In addition to the constructive elaboration, the stairs, shelter structure, temporary measures, demolition and finishing can be offered separately. Ask who checks the final dimensions and how changes are processed. A clear division of tasks prevents the staircase from being produced while the opening has not yet been coordinated. Use the quote comparator to keep missing parts visible.
Your preparation in four steps
- Structural floor change
- Stairs and railings
- Assembly and temporary facilities
- Restoration and finishing
Frequently asked questions on this topic
Is a stairwell the same on every floor?
No. A wooden beam layer, solid concrete floor and prefab floor system have different properties and carrying routes. The location of the opening is also relevant. Therefore, collect the floor structure and available system data before developing the solution.
Who determines the size of the stair opening?
The size must match the stairs, free height, floor thickness and structural support. Have the designer, staircase supplier and structural engineer use the same data. Only order the stairs based on the agreed and checked dimensions.
