The Mumbai Coastal Road Project Package 1 includes the construction of a 3.82 km-long, 8-lane road section over reclaimed land. To create green spaces, in the congested city, an area of approximately 60 hectares from the sea is reclaimed and protected from the sea by a seawall. The challenge for reclamation in the Haji Ali Bay area is the presence of marine deposits of thickness varying from 1 to 6 m on rock strata. Shear strength requirements of marine deposits are not satisfied, and settlement issues will be observed during service. Crushed rockfill was the approved material to be used for reclamation. Hence, ground improvement by stone columns was suggested. As per employers’ requirements, the final formation level is + 8.50 m CD. The reclamation fill, when placed on site, is stable only up to + 6.1 m CD. The shear strength of the clay present in this zone is estimated to be 19.5 kPa. With this shear strength, the fill cannot sustain further filling up to + 8.50 m CD. Also, consolidation settlements in the region would continue for a period of 23 years on unimproved ground. The design of the stone columns was done to restrict total residual settlement at 100 years to 65 mm.
