Cost-Effective Foundation System for Medium Rise Residential Building on Typical Soft Kolkata Soil
In present scenario due to rapid growth in population, it is not possible to construct each and every residential building on hard soil. Some time, it is necessary to construct building on soft soil. One of the examples is Newtown, Rajarhat, Kolkata. Rajarhat is a developing area in Kolkata where most of the residential buildings are medium rise, i.e. four or five storied. In that area, soil consists of very soft clay having very low value of SPT value (2–5) up to a depth of 12 m or below, followed by hard strata. In most of the cases, shallow foundation cannot give feasible solution and structural designers prefer pile foundation before adopting other alternatives techniques to improve the soil. Pile foundations are not very cost effective. Cost of the foundation constitutes a significant part of the total cost of the structure. Hence, reduction in cost of the foundation leads to reduction in total cost of the structure. In this study, an effort has been made to recommend feasible cost-effective foundation system by using ground improvement technique (by using stone column) vis-vis pile foundation. A typical medium rise building (G + 4) has been chosen on a typical soft soil profile, typical to Rajarhat area. A comparative study has been made to suggest cost-effective foundation system for medium rise residential building in that area.
