i360 jacking tower takes attraction to new heights

Brighton i360 Jacking Tower

Progress at the Brighton i360 is on schedule, with the completion of the specially engineered temporary 60 metre high “jacking tower”, which can be seen from far and wide.

Said Eleanor Harris, CEO of Brighton i360, “If you have been on the seafront over the past couple of weeks, you can’t have missed the fact that the i360 construction is now well underway.”

David Marks, architect of the i360, said: “Building the i360 is a formidable engineering operation. The jacking tower is a vertical factory, a vertical production line.  Individual steel cans go in at the bottom, and the finished tower comes out of the top, with the steel cans safely bolted together and clad in an eye-catching, diaphanous, aluminium veil.”

The first few steel ‘cans’ were lifted into place conventionally using the giant 100 metre high crawler crane, nick-named T-Rex by the site team, but as the tower reaches higher into the sky, the jacking tower, designed by the i360’s main contractor, Hollandia, will be used to lift the tower up, allowing a new can to be skidded in underneath.

The new can will be bolted into place, and this process will then be repeated until all 17 cans are adjoined and the i360 tower is complete.

Seven of the 17 steel cans are already in place – numbers one, two, three at the bottom, and the top four cans (cans 14, 15, 16 and 17) and the tower is now 64 meters high with the top just peeping out of the top of the jacking tower.

That first jacking will see the jacking tower lift around 315 tonnes, made up of the top four cans and the counterweight which will be used to help the i360’s viewing pod rise and descend once the attraction is open. The engineering team will then slide can 13 into place and once that has been bolted to the cans above, the process can begin again.

This operation will be carried out ten times over in the coming weeks. Can three – which is currently in place but will be removed prior to the first jacking in order to place can 13 – will be re-installed at the end to complete the 162 metre high tower.

While up and lifting, the jacking tower will also be used to fit the exterior cladding to each part of the tower, which is designed using a 5mm thick skin of expanded aluminium. The top can – can number 17 – already has its curved cladding panels fitted.

The final lift – all the cans from number four to number 17 – will be 980 tonnes and the tower is scheduled, subject to weather conditions, to be in place by early September.

About Brighton i360

At 162 metres high, and with an observation pod rising to 450 feet, the i360 will be the tallest observation tower outside London, a vertical cable car offering a new perspective on the fun loving seaside city of Brighton. Sited at the root end of the historic West Pier on Brighton’s seafront, the i360 has a slender, elegant design, with a futuristic pod allowing 200 visitors at a time to enjoy the surrounding view as it slowly unfolds. The visitor centre incorporates a 400 seat restaurant; a shop; children’s play zone; exhibition space; tea rooms; and conference and event facilities.
