a.) See the note included in detail 5/SR501. The requested information is provided there.

b.) The actual undercutting will depend on the soil conditions encountered as the foundations/slab are excavated. The conditions should be observed by the testing agency to determine if the design bearing capacity is achieved at the footing subgrades and a proofroll observed by the testing agency within the slab area (there are references to the foundation subgrade and slab subgrade being observed by the testing agency in our report).
