The project's concrete framework was topped out six weeks ahead of schedule in March, and now the final piece of the tower's 60m spire has been lifted into place. The installation of the spire was completed in just 14 days. Mace has been delivering project management services on the project for Vinhomes since 2015.
To achieve the early topping out of the structure, Mace worked to optimise the typical floor cycle time of four days and regularly completed entire floors in just three days.
For the installation of the spire, the Mace team worked closely with the contractor to plan and finalise the installation methodology and the subsequent removal of the luffing tower crane. As a result the work took two weeks less than originally scoped.

Landmark 81 – which would now tower 150m over the Shard in London – is a mixed-use 81-storey tower containing high end apartments, a hotel, executive floors and observatory decks. It is the centre piece of Vinhomes Central Park, a development that includes 18 towers in total.
The project has been record breaking since it began, with the earlier stages requiring Vietnam's largest ever concrete pour. This involved excavating 25,000 cubic metres of soil, installing 6,500 tonnes of reinforced steel, and using 17,000 cubic metres of concrete to create the 8.5 metre thick pile cap for the tower's foundations. This engineering feat required detailed logistical planning, including the construction of temporary roads and walkways, staircases and specially designed cooling systems.
John Campbell, Mace's Country Manager for Vietnam, said: "Landmark 81 is a truly iconic project that will change the face of Ho Chi Minh City forever. It's an honour for Mace to be able to help deliver such an important scheme – and I believe we've made a real difference over the last three years, helping to ensure that such a complex job is delivered ahead of schedule."
