Timing of installation
Initial information about our stairs and expected prices can be found on our web site. Mrail can provide additional free information, consultations and give more precise quotation based on provided plans or site measurements.
Staircase structure should be erected before wall, floor finishes installation, because stair connections to support should get hidden behind wall and floor finishes. Also, stair skeleton may be used as a construction stair. So, stair building process should start as soon as all relevant information are available. Typically, that is when the measurements of stairwell framing are taken and thicknesses of anticipated finishing materials are given.
Shop drawings are typically produced in 1-3 weeks up on quote acceptance and collection of necessary information and site measurements. After shop drawings are approved should be no changes in dimensions especially thickness of the finish floors.
In our shop drawings we indicate basic measurements for finishes by others to enable proper coordination between trades. Stairs are not an independent object. They are integrated into the stairwell opening. The floor becomes a step platform. Floor end edge (nosing) extends over the stair and becomes the edge of the top step platform. The floor edge must maintain planned position, relative to other steps, to keep run and rise uniform. Mrail makes shop drawings showing all details relevant to stairs. Stair details must be agreed and understood when shop drawings are approved. GS and trades must follow the shop drawing and install the floor edge and other finishes as planned.
Mrail gives an instruction how other finishes (floors, walls, fascia, nosing ..) should be applied, but Mrail is not supervising other trades. Common mistake is that that other trades are left to do their work on their own not knowing how stairs and guards are going to be finished. When we come to do our finishes, it is usually impossible or costly to fix the deviations. Usually, a compromise is made on the expense of the design.
Next phase is fabrication and installation of a stair skeleton. Expected skeleton installation is in eight weeks from approval of shop drawings. Skeleton should be installed before installation of finishing materials in the house. Plates and hardware are sunk into substructure to allow finishing materials to run over and hide the hardware. Skeleton may be used as a temporary construction stair. Adopting it for use (like building guards..) is by others.
After stair skeleton installation, house floors, fascia, walls should be finished. Steps finishing material, glass, handrails are installed at the end of construction. We need 6-8 weeks notice to prepare and install our finishing materials.
