A base plate is a component at the foot of a scaffold that transfers forces into the support beneath it.
What does this mean for your project?
The base plate belongs to a wider support arrangement. Its presence does not establish that paving, a roof or a covered opening is suitable to receive the structure. The provider needs to consider the proposed scaffold together with the actual conditions beneath its footprint.
Supply information about known basements, underground services, level changes and recent excavations. A photograph of the paving reveals only part of the situation. State uncertainty explicitly instead of describing an apparently hard surface as evidence of adequate strength or suitability.
During use, report changes around supporting components through the agreed contact route. Lifted paving or nearby groundworks can be relevant. Do not reposition a plate or add another supporting layer yourself in an attempt to correct an observed problem with the installation.

One more
thing.
Does a base plate make every surface suitable?
No. Suitability depends on the complete support arrangement and the actual conditions at the location.
Can paving beside a base plate be replaced?
Coordinate groundworks and maintenance around the support with the responsible party beforehand. Do not change the conditions unnoticed during scaffold use.
