Approximately 40,000 workers are expected to be on-site at the peak of construction activity for Expo 2020 Dubai as it crosses the two-years-to-go mark, according to officials.

On Saturday, Dubai marked the milestone with a choreographed show and three-minute projection on the Burj Khalifa, part of a larger public event attended by thousands at Burj Park in Downtown Dubai..

The event included five hours of live music performances, illuminations and dances from around the world, as well as artistic exhibitions and global cuisines.

According to Expo officials, construction on the three thematic districts that make up the site is “well advanced”, with the foundations and structural works already completed, with approximately 243,000 cubic metres of concrete poured.

Currently, precast production and installation is taking place, alongside face, mechanical, engineering and plumbing (MEP) and public realm works.

So far, more than 44 million work hours have been completed and there are currently about 26,000 workers at the Expo site. This figure is expected to rise to 40,000 workers – both manual and non-manual – are expected on site in H1 2019, including employees of third party stake-holders and participating countries.
