Before conducting any excavation, depending on site and soil conditions, we can estimate the maximum settlement and extent of settlement that is going to occur when a excavation is carried out at that site. It is to be noted that Peck's analysis was based on experiments done over sheet pile walls. Therefore, if the rigidity of the structural members can be increased the settlement values can be minimized and whatever settlement we could have got for a sheet pile wall in zone III can be found to fall in zone II due to a more rigid structure. Hence after finding out the extent of settlement it has to be judged whether any surrounding structure falls within that range.
