Thank you for the very useful information - I am an Architect here in Nairobi
Building with Deep basements are now becoming the norm here as space is expensive
I am planning on excavating an area of 25m X 40m X 12m Deep
There is a 8 storey building located approximately 3m away from the 25m side
What precautations can / should be taken to prevent the pit from collapsing and the tall building from falling!
Any assistance on this will be much appreciated
