An imposing new presence will soon alter Ho Chi Minh’s skyline. The 461.2 metre-high Landmark 81 will become the tallest skyscraper in Southeast Asia and the sixth tallest in Asia. Taking the lead in bringing this product of bold vision and innovative design to life reinforces Aurecon’s position as one of the world’s leading engineering consultants for supertall buildings.
The boldly designed Landmark 81 superstructure will rise from the centre of the multipurpose Vinhomes Central Park urban development and will meld business with lifestyle through structures of unprecedented scale in Vietnam. Aurecon is partnering with the Vincom Group, a local company that has been commissioned to build the structure, comprising residential, retail and leisure spaces.
Currently at the detailed design stage, the project is a collaboration between developer Vincom Group; architects Atkins; interior designers Wilson Associates; structural engineers Arup; contractor Mace; and Aurecon, who is managing all engineering work related to the building services, as well as the lighting and the facade of Landmark 81.
“As Aurecon continues to grow in Asia, we want to build long-lasting relationships with key clients and the Vincom Group, as Vietnam’s largest developer, is a valued customer,” says Aurecon’s Tuyen Bui, Country Manager – Vietnam. “In fact, Vincom Group’s strategy aligns with our own, in that we both want to grow rapidly in this region and extend the quality services we offer our customers. The Landmark 81 project has brought together Aurecon teams from three engineering disciplines; a great reflection of the broad array of expertise we have in-house.”
Among the notable challenges in designing Landmark 81 was tight time pressure, with Aurecon given only three months to produce detailed designs for the building services. Demonstrating its agility, the company developed designs in the Revit platform, which not only optimised efficient construction programmes for the project but enabled 4D BIM-based mapping that tracks progression over the building’s lifetime.
Aurecon applied innovative, smart solutions throughout. For example, to give the building a smoother appearance, in a first for Vietnam, a central air conditioning system will supply all residential apartments – avoiding unsightly individual units. The HVAC system has to meet Green Building standards, and accordingly waste heat from the air conditioning plant will be recovered and used elsewhere, such as providing hot water. To accommodate this system, Aurecon created a 36 000 m2 system across three basements, which includes concrete plenums and jet fans along the dividing walls to eliminate the need for ceiling ductwork and increase the available headroom. The building is expected to gain LEED certification on completion.
The firefighting system is designed to enable the podium and three basement levels to utilise water tanks from neighbouring buildings. Gravity-activated, the system cuts costs on the pumping system and offers a safer design.
Strong emphasis has been placed on the energy efficiency of the lighting requirements: luminaires will use LEDs and daylight sensors will ensure that lighting is only activated during evening hours to maximise energy savings.
Principal Lighting Designer at Aurecon, Angela Woo Scott, says it is important to consider both the functional and aesthetic advantages of each lighting option. “Lighting such an impressive building is about achieving the right balance and ensuring a functional yet striking end result. We have worked with the developer and architect to highlight the elegance and luxury of the development without being excessive.”
Features, such as the entrance facade, presented challenges that Aurecon has overcome through teamwork and intelligent design. This 26 metre-high glass-and-stone system facade had few framing members. However, through the synergy between Aurecon’s internal engineering and lighting teams, a solution has been found.
Scheduled for completion in 2018, the 241 000 m2 Landmark 81 superstructure will include a five-star hotel, serviced apartments, residential apartments and retail space. This iconic building will not only stand as a tribute to extraordinary vision and courageous innovation, but as an eye-catching testament to collaborative design.
