i360 Site Tour

On  Thursday September 10th 5 BHT clients visited the Brighton i360 site, where the world’s tallest moving observation tower is under construction.

i360 Site TourOnce completed, the tower will stand at 162 metres tall, which is 60 metres higher than Brighton’s tallest building, Sussex Heights. Advertised as a ‘vertical pier’, the i360 will have 120-mile views and will accommodate up to 200 people per ride.

During the tour the i360’s Public Liaison Officer spoke in detail about the material used and the building process. The structure is formed of 17 prefabricated ‘cans’ which were slotted in under one-another by lifting the shaft above using the ‘jacking tower’. The final can insertion required the jacking tower to raise 980 tonnes of steel. The steel cladding, which comes from Hartlepool, will wrap the vertical tower and will off-set wind, and consequently vibration. The tower, however, will still be liable to sway up to one metre. The glass pod is formed of 24 segments which are currently under construction in France. The Public Liaison Officer also spoke of the project’s energy efficiency; energy generated from the pod’s descent will account for around 50% of energy required for the next ascent.

i360 Site TourAs part of the £46million project, an original toll booth from the West Pier is being restored and a second replica is being produced to flank the tower; a nod to the area’s heritage.

The project is on schedule to open during Summer 2016.

Brighton Sewer Tour

Clients of various BHT projects visited the captivating hidden depths of Brighton’s Victorian sewer network, which dates back to the mid-19th century and spans 44 miles.

Brighton Sewer TourEntering the system via Pier Arch 260, the group watched a short video about the sewer system before putting on hard hats, head torches and gloves and entering through a heavy, water-tight door into a safety passage. At the end of this tunnel we were able to look down to the East to West intercepting sewer; an egg-shaped chute designed to control water flow and break down solid matter.

Sand from the beach was used to cement together the red bricks which form the perfectly circular tunnels. Sewage was initially discharged into the sea, however after a campaign to build an intercepting sewer, waste water was taken out of town.

During the tour we descended down to the Overflow tunnel, which leads to an outfall on the Albion Groyne. In the 1990’s Europe’s largest storm water storage tank was constructed under Brighton beach. It is 3 miles long and a diameter large enough to drive a double-decker bus along the inside of the tank. The storm tunnel comes into use during extreme and prolonged weather, after which it is pumped back into the main sewer system.

At the end of the tour we switched on our head torches and walked single-file along a fascinating 200-yard stretch of the Overflow tunnel. At our feet, a small trickle of clean water ran along the length of the tunnel. We returned to ground level (and fresh air!) via a short vertical ladder which took us up through a man-hole cover in the Old Steine.
