The Sky is the Limit for Brighton's New Attraction page 2 of 5



A steady flow of trucks arrived every five minutes at the i360 site since the early hours of the morning bringing 2,640 tonnes of concrete and pouring it into a huge reinforced hole with a fenced space for the shaft of the Brighton i360 in the centre.

There were as many as 200 lorry visits to the i360 site each day - coming from plants in Shoreham, Burgess Hill and Chichester. A weekend date was picked for the pour, as so much concrete was needed, the team had to pick a day when they could have sole use of these three plants.

Each lorry was emptied in a just a few minutes and the concrete took around two hours to set. As each lorry arrived the concrete was transferred into a pump tray. It was then hosed in by one of three pumps.

The concrete forms the foundations of the tower.

There were four pours in total. The second major concrete pour was on June 10, once the first batch has had time to cool. Then smaller ones on June 11 and 12. It was done in stages to control the temperature of the concrete during the curing stage.

Contractors from Hollandia in the Netherlands and local firm Mackley are supervising the project. There are 50-60 construction workers on site and ten marshals to make sure everything runs safely and according to plan.

The team worked closely with Brighton & Hove Council to make sure traffic was not affected by the activity. All the trucks were being managed from a holding site at Shoreham Port and
truck departures carefully staggered to make sure they do not have to queue up on the seafront.

All this is in preparation for the arrival of the steel 'cans' that will make up the viewing tower, which will arrive in two barge shipments from the Netherlands directly on to the beach beside the site by the West Pier, weather depending.



The barges arrived at Brighton Beach from Holland to deliver the steel cans which are being used to construct the 162 metre high observation tower this summer. Seven thousand tonnes of fill, gravel, shingle and chalk was sucked out of an 8.5 metre deep hole as construction on the Brighton i360 stepped up a gear.

A Hitachi SCX8000 crawler crane was used in moving the heavy equipment needed to reinforce the basement as the construction team dig down to the 8.5 metre depth. This crane was selected because it has an unusual secondary feature: its high erformance
exhaust filter cleans the air using anti-pollution technology.
