I can answer questions related to rock blasting, rock and soil excavation (such as tunnels and highway cuts), stability of such excavations, and foundations in rock and soil. I can also answer questions related to geology and mining.

There are no two projects that are exactly alike, and not everyone can deal with the uncertainties inherent in designing with real earth materials.
The perfect blast, each and every time.
In geological engineering, unllike other engineering fields, the behavior and properties of the engineering medium (rock) cannot be fully controlled by Man. This makes geological engineering a complex mix of judgment, statistical evaluation, risk analysis, and explicit engineering calculation.
People think it is cool it is to perform blasting consulting. It would be much more cool if it were not necessary to drill holes in rocks first. Drilling a hole in a rock is an inherently difficult and refractory task.

Here are my reactions to your questions in numerical order: 1. Not knowing the details of your contractual language, I can only respond generally. Whether the Engineer has the contractual basis
1. The natural granite could be leveled but only at great cost. I know of no technique for sawing rock horizontally, except for wire saws that are used in quarrying operations, and the problem there
Get a copy of the soil/foundation report and review whether it considers the possibility of limestone bedrock. You can then contact the soils firm that did the work with any specific questions. Limestone
I suppose you could apply the conversion but the problem is that the seismic coefficient is defined for generalized horizontal ground motion and the peak particle velocities are measured in two horizontal
Yes you can pour concrete onto solid rock, the only exception being that some rock types, chiefly those that contain a lot of hydrated silica like chert, may adversely react with the concrete. That is
