Partial Underpinning a Five-Storey Building

Partial underpinning is often not accepted because of dangerous damage that may be caused by the redistribution of stresses in the superstructure. A five-storey building was partially underpinned successfully. To give stability to the building only a small number of piles, about 70% fewer than with the conventional method, were used. The results observed have proved the success of the partial underpinning
