Measuring 462 metres, Landmark 81 will be one of the tallest residential buildings on earth. Commissioned by property developer Vingroup, designed by architectural firm Atkins, structural design consulted by Arup and built by construction companies Mace and Coteccons, it will make a statement in one of Ho Chi Minh City’s most prime locations facing the Saigon River. This 81-storey skyscraper will comprise a hotel, serviced apartments and a high-end shopping centre.
Perfect for heavy loads and free fire protection
The 3,600 tonnes of sections were produced by ArcelorMittal Europe – Long Products’ Differdange mill. The composite design of concrete and HISTAR® steels is ideal to carry heavy loads. The concrete walls contain multiple jumbo sections acting as vertical columns to carry the weight of the building. The concrete surrounding the steel columns also acts as a free fire protection.

More floor area thanks to HISTAR®
A key advantage of HISTAR® steels will be an increase in saleable floor area. Vietnam is one of the few countries in the world where developers have to sell the net area of apartments or offices instead of the gross area. Inserting HISTAR® sections into the walls will enable builders to reduce their width, freeing up additional saleable area at prime cost. By selecting HISTAR® 460 columns in composite walls, the structural engineer Arup succeeded to maximize the so-called “carpet area” for the benefit of the investor Vingroup as well as the future tenants.
In total, three lots of HISTAR® sections will be delivered to the steel fabricator QH Plus. The first lot arrived in Ho Chi Minh City in early September 2016. Completion for Landmark 81 is expected in early Q1/2019.
