Building On Very Different Ground Types

[YuleMsee]

The attached layout is of the said apartment building, I'm proposing to introduce a movement joint along Gridline E. The diagonal lines divide the ground into zone A, B,and C representing the encountered ground conditions.
A - Rock (600KN/m2)
B - Weathered rock (400KN/m2)
C - Well consolidated non expansive clay, it runs deep (200KN/m2)

Still waiting for the geotechnical report but the figures in brackets are the expected bearing capacities from experience.

To my question, is there a way to keep differential settlements at near zero other than using a raft foundation?

Yes. Use lighter pressures than "highest usually used". I'd guess this would not be difficult for that site.

@oldest guy, I'd end up having some combined footings on some columns bases in the clay area, but otherwise not hard to achieve. Crossing my fingers
