Case Study: Burj Khalifa

04 Oct 2021
The Highest Hatch in The World
Surespan design and manufactured the highest hatch in the world, a 600mm diameter submarine access hatch located 816 meters up on the Burj Khalifa.

The Burj Khalifa is the world’s tallest building, soaring 828 meters above Dubai. The design for the 162-story tower combines local cultural influences with cutting-edge technology to achieve high performance in an extreme desert climate.


The Project:

As part of the 1.5-billion-dollar mega Downtown Dubai project, the government of Dubai decided to build the world’s tallest building. This project redefines what is possible in the design and engineering of supertall buildings.


 Architect firm Skidmore, Owings & Merrill design inspiration for the tower was taken from the shape of a regional desert flower the Hymenocallis, also known as desert lily and the patterning systems embodied in Islamic architecture.



Surespan was selected for their engineering expertise, innovative designs, and unique skills.

The team designed and manufactured a 600mm diameter, polish grade 316 stainless steel simulated submarine access hatch with handwheels. The hatch is located at 816 meters and is used for maintenance access to the aircraft warning lights.



The hatch was engraved with all the architects and contractors that worked on the project and was used in the ‘topping out’ ceremony
