Located in the vibrant cultural and heritage district of Bugis in Singapore, DUO is a new real-estate development which opened its doors on 15 January 2018. This high rise has 2,082 tonnes of HISTAR® steel sections in its foundations, with the steel produced by ArcelorMittal Europe – Long Products. The use of our steel sections allowed the contractor to save both time and weight.
DUO comprises residences, offices, a hotel and retail space. It is designed by German-born Ole Scheeren, the architect behind the design of landmark projects such as the CCTV headquarters in Beijing, the MahaNakhon, Bangkok’s tallest skyscraper, as well as The Interlace, iconic residential development in Singapore and World Building of the Year in 2015.
Weight saving of 20% thanks to HISTAR®
ArcelorMittal contributed to the construction of the DUO Residences tower, which is still under construction. We supplied 2,082 tonnes of HISTAR® 460 steel sections produced in Differdange, Luxembourg, which were used to build the foundations of the tower using the top-down method.
What is the top-down method?
The top-down method is a composite method to build foundations. King post piles are put in the ground and while digging around them, slabs of concrete are put on top of them. At the same time, construction of the top structure starts. When arriving at the bottom, concrete is put around the king post piles for fire resistance. When the foundations of the building are completed, the building is already partially built, resulting in reduced construction time for the contractor.
The top-down method using our steel sections offers many advantages:

DUO is developed by M+S Pte Ltd, owned by Malaysia’s strategic investment fund, Khazanah Nasional Berhad and Singapore’s state-owned investment company, Temasek Holdings.
