Top five construction updates from Expo 2020's Dubai site
Updates about infrastructure, structural, equipment, and scheduling activities at the Expo 2020 site have been revealed
Key construction updates about the Expo 2020 scheme in Dubai have been revealed by the event's organisers.
Main construction works are underway on site, officials have revealed.
Expo 2020, to be held in Dubai, will be the first World Expo in the Middle East, Africa, and South Asia region.
The following pages outline construction updates from the mega development's site.

At least 17km of logistics roads have been constructed – using recycled concrete – around the site.
The roads offer site access for equipment and materials.
Two contracts worth a combined $330m (AED1.2bn) were awarded in March 2017 for the construction of the Seventh Interchange on Sheikh Zayed Road, as well as expansion works for Al Yalayis and Al Asayel Roads in Dubai.
Mattar Al Tayer, the director-general, and chairman of the board of directors of the Roads and Transport Authority (RTA), said the contracts were part of the road projects approved for easing mobility and accessibility to the Expo 2020 site.

Infrastructure work is also advancing, with three power substations, being developed by Dubai Electricity and Water Authority (DEWA), nearing completion.
This July, DEWA revealed that a 132/11 kilovolt (kV) main substation it is developing at the Expo 2020 site is 71% complete.
Construction of the Opportunity sub-station is progressing to plan, DEWA officials said.
DEWA revealed Opportunity's development costs amount to $38.6m (AED142m), of which $22.4m (AED82.3m) is allotted for the plant, and $16.2m (AED59.7m) for the facility's 132kV cables.

Up to 12 tower cranes are operational at the Expo 2020 site, and 10 more will be erected in the months to come, the event's organisers said.
Each week, 6,100m3 of concrete is poured on-site, the organisers added.
In December 2016, it was revealed that Liebherr Middle East and Dutco Balfour Beatty (DBB) had modified a standard duty-cycle crawler crane to power a vibro hammer without a separate power pack – saving time and money in the execution of piling works at the Expo Village in Dubai.
It is estimated that the modification to allow the new 100t HS 8100 HD crane to drive the vibro hammer that installs pile casing using its own engine has resulted in a 20% increase in the productivity of the operation.
All heavy construction works at the Expo site will be completed by October 2019, a full year before the Expo opens on 20 October, 2020.
Pavilions that are under-construction for select participant nations have reached above-ground level, marking a key milestone in development works on the 4.38km2 site.
Work on the districts began in March 2017, after a $599m (AED2.2bn) construction contract was awarded to Dubai contractor, Al-Futtaim Carillion.

Up to 17 projects are underway on the construction site, and more are due to come online in the next few months, Ahmed Al Khatib, the vice president of real estate and delivery at Expo 2020 Dubai, said.
April 2018 will be a key period for the site, "when participant nations begin to take over their plots and start constructing their pavilions", Al Khatib added.
Each building within the themed districts is planned to meet LEED Gold standards, the event's organisers reported.
During operations, basements developed as part of new buildings will be turned into an underground rail and road network to support logistics for pavilions, shops, and restaurants, without disrupting the visitor experience.
