The growth in infrastructure sectors of transport and building sectors including information technology (IT) services has been phenomenal in recent times. Many such centers are coming up across the country with high towers to achieve high workforce density in smaller footprint. However, land space being limited, most of these developments are now being pushed to sites with difficult subsoil and ground conditions. Though the structure demand on the foundation remains high to support a dense and high development, the poor subsoil conditions require special measures in both design and execution of the foundations. The current project features construction of high-rise towers for IT service buildings at a site in northern part of India. The site is in a high seismic risk zone and the soil is found susceptible to liquefaction due to presence of fine sand in the upper layers of the subsurface. The poor subsoil conditions and high building structure loads necessitated selection of large diameter bored cast-in-situ concrete piles as foundation system. Special approach was used to ensure that the foundation system was robust and designed considering the worst possible load conditions. To ensure transfer of seismic forces from structure to the firm ground beyond the liquefaction zone, verification of pile capacity through load testing and pile quality assessment through integrity tests. During execution of piling works challenges for pile shaft formation due to the loose fine sand zone in upper layers posed problems with bore stabilization and pile concreting. Despite the many challenges, the foundations are successfully executed to support the vital infrastructure development. This paper presents the challenges and solutions adopted in both the design phase to ensure adequate design of piles considering liquefaction potential of soil and in the execution of bored cast-in-place concrete piles in the predominantly silty fine sand strata.
