We Build the Foundation of Smart Cities

Project Description

The integrated resort being built on Singapore’s Marina Bay waterfront by Las Vegas Sands forms an integral part of the city state’s ambitious development plan for the Marina Bay area. Bachy Soletanche Singapore were already on site to carry out the advanced works contract to clear an old seawall mole buried in the reclamation.

This contract also formed the cellular retaining walls for Tower One and Two where the abandoned mole encroached on the footprint of the hotels. Known as the doughnut and peanut these were integrated into the final structure as the basement retaining walls.
