Each time we jack up the tower it is an incredible feat of engineering. The 16 tonne steel collar is lowered within the jacking tower and attached to a can. Four strand jacks, each with a lifting capacity of 450 tonnes, then gradually jack up the cans stacked above, high enough so a new section of tower can be slid underneath.

The fi rst jacking session saw the tower lift 315 tonnes and the fi nal lift will be almost 1,000 tonnes. Overall we have 9 lifts to make before we slot the last can in.

What’s going on inside the tower?

The jacking tower is broken up into different levels – with the cladding room the level nearest the roof. Inside there a team from James and Taylor,

the specialist cladding fi rm, is meticulously adding perforated panels to the side of each tower can. The cladding is an important part of the tower and more than 320 panels of cladding will be added in this room over the next couple of months

David Marks, the i360’s architect, previously described the jacking tower as “a vertical factory” adding: “Individual steel cans go in at the bottom, and the fi nished tower comes out of the top, with the steel cans safely bolted together and clad in an eye-catching, diaphanous, aluminium veil.”

Where can we watch the lifts?

The jacking takes 2 days to complete and you can either watch the action on our webcam or sign up to our newsletter / check the website for updates on each lift. We have some incredible time lapse footage on the site.
