In developing country like Pakistan, population growth rate is h i=h that has caused increased in urbanisation. To accommodate increased population. there is a dire need of high rise buildings especially in most densely populated  cities of the world . Consequently. traffic and parking issues have also increased. To cope with these issues, deep excavations for underground facilities as well as construction of high rise buildings in  urban  areas  is carried out adjacent to existing historic  or old buildings founded on shallow foundation. Excavation may induce unfavourable ground deformations that can affect adjacent structures. This condition leads to a big challenge for civil engineers to assess and  protect the integrity of the historical structure. This research presents three-dimensional coupled consolidation analyses (using  clay  hypoplastic  constitutive  model  which  takes  account  of small-strain stiffness) to investigate the responses of a shallow foundation to adjacent excavation at different depths and clear distance between the footing and diaphragm wall i n soft clay. It was revealed that the excavation depth and the clear distance between the footing and the diaphragm wall have significant effect on induced settlement and lateral  movement  due  to  excavation.  Moreover,  the apparent  losses  in  bearing capacity due to induced settlement of the footings located at 1.0, 1.5, 2.0, 4.0, 6.0, 8.0
m from the diaphragm wall are 1.65, 1.73, 1.81, 1.70, 1 .53 and 1 .30 times of ultimate capacity, respectively.},
