- In Simple terms, the SBC (Soil Bearing Capacity) test wasn't done to determine the actual type of soil in the area; secondly, there must have been a problem with the foundation design and also the Column Base/Footing Design.
A photo of a storey building house crumbling down from its foundation has sparked debate and criticisms online with netizens claiming the house might have been constructed by two different contractors with the soil bearing capacity test not done well.
The twitter responses has shown how we have so many construction experts on twitter who need to be consulted when need arises to counter such challenges.
The experts were very eager and willing to give their remarks as consulted

My pov...This building wasn't designed for more than 1 story...Why...Check the blocks on the perimeter, show that construction commenced kitambo kidogo then stopped gathered some money got greedy forgot the type of foundation they had and decided to add more stories

@HumphreyAdenya
My take: Differential settlement may not be the case as shown in red. The level of the ground floor seems not to be settled much to be visible.
Concrete strength
The ground to first floor columns buckled meaning there must have been an issue with the concrete strength attained.
@LoveLadyBird_
The base columns are weak. The steel used to reinforce the columns do not have had the bearing stress. As you can see, the whole base, which was a space, certainly it was going to be used as packing. So the strength of the steel used is less than the recommended should be HB35.
This is a call for collaboration and proper survey before starting a building's foundation since the foundation is the determinant of its fall or stability.
