Yes. The trench is for what's called a footing.
This footing is a mass of concrete that supports the building and keeps it from sinking into the ground.

How close can you excavate to building foundations?

It isn't as critical as to how close you excavate to building foundations. You want to be more careful not to excavate below a building's foundation. As a geotechnical engineer, we recommend that excavations for additions or appertenant structures not be extended within a 2 horizontal to 1 vertical oversize area extending down and away from the outside edge of the existing building's foundation. Hopefully this helps.


What kind of building rests on a foundation?

Foundation is the underground or the substructure part of a building that transmits the load of the super structure to the ground safely. it is the lower part of building on which the whole structure rests. it may be made up of stone masonary, PCC or RCC. depending the width to depth ratio it may be a shallow foundation or a deep foundation. shallow foundations are used for smaller structures and shallow foundations are used for multistoried buildings where the load carried by soil is more.

What is the Concrete slab at entrance of building?

The slab is part of the overall foundation and footing system of the building. If it is outside, then it doesn't need to be water-proof or damp-proof. All interior foundation walls need to be water-proofed or damp-proofed depending on the hydrostatic pressure, found in the surrounding earth. Foundations and slabs-on-ground should be placed on good, compacted soil, or other acceptable aggregates. A solid slab should be a minimum 100mm thick.
