Velana International Airport Piling and Substructural works

A piling design that uses prestressed, pre-cast spun piles of 600 mm diameter with an internal core diameter of 400 mm

Velana International Airport is a unique project that features many constraints, especially in regard to the substructural works. The challenges arise due to the nature of the existing topography. Lose sands and high-water table levels are examples of the key constraints. Using innovative design and frequent soil investigations, BCG in collaboration with international design firms have designed a complete solution.

A piling design that uses prestressed, pre-cast spun piles of 600 mm diameter with an internal core diameter of 400 mm. The project consists of 1475 piles of a length varying from 12 m to 16 m, each pile is designed with a load bearing capacity of 1600 kilonewtons.
