Soaring 461m into the air, the Landmark 81 Tower topped out in Jan 2018 to become the tallest building at the banks of the River Saigon. The building comprises commercial, retail and luxury residential apartments with a gross floor area of 241,000m², forming a centrepiece of a new residential development.
The shape of the building resembles a bundle of bamboo canes to reference the area’s agricultural past and the nation’s much revered home-grown resource.
Arup provided geotechnical, structural and fire safety strategy for the landmark tower, developing practical solutions to realise the architect’s vision.
Project Summary
461m the tallest tower in Vietnam
81storeys
241,000m²GFA
The 81-storey tower with three levels of basement is built in an area with exceptionally poor quality soil, presenting a number of challenges to the design team. The design solution adopted a thick raft supported on barrette pile, which allowed for maximum flexibility for the subsequent development of the design even as the foundation was being constructed - a necessary requirement imposed by the fast-track design and construction programme.
As the current local fire safety codes are not suitable for a building of this height, Arup was commissioned to design the fire safety strategy and provide expert advice based on the internationally recognised NFPA 5000 Building construction and Safety code.
This is the first project in Vietnam on which lift assisted evacuation strategy is used as a means for evacuation for people with various mobility conditions. The benefits of this system included reduction of risk of injury and total evacuation time.
