HS2 has begun the recruitment process for members of its design panel.

Origami-inspired folding bridge could aid disaster relief Japanese engineer Dr Ichiro Ario has designed a new mobile bridge based on the principles of origami, which could speed up emergency relief to cut-off areas following natural disasters.

The Mobile Bridge Version 4.0 (MB4.0) can fit in a car trailer, and unfolds in a scissor-like fashion to span small rivers and ravines. Its first construction test took place last month over the Hongo River in Fukuyama City, near Hiroshima in southwest Japan. “From this test of a new bridge concept, the next generation of bridge technology starts on a new stage in the field of bridge engineering,” said Dr Ario, who is assistant professor at the Institute of Engineering, Hiroshima University. “It is possible to use a real deployable and smart bridge with a scissor-type bridge system using this structural theory.” From arrival on site, MB4.0 takes approximately one hour to deploy, with the actual extension time taking just five minutes. It is claimed that the patented scissor mechanism outperforms the older block assembly method of construction, making MB4.0 “the world’s lightest, fastest, largest, strongest and lightest expanding temporary bridge.” Source: Hiroshima University, Japan Construction Method and Machinery Research Institute, Hoshikei-kinzoku The new technology uses a scissor-type mechanism, enabling rapid bridge construction. No foundation construction or crane operations are required to deploy the bridge, and it is hoped that its speed and flexibility could lead to faster relief reaching areas in need following natural disasters such as earthquakes, floods, tsunamis and landslides. Dr Ario believes MB4.0 could also have other applications, such as providing structural support to existing bridges in need of repair, or as an alternative crossing where a bridge is closed for maintenance. “I will further promote the development and evolution of MB4.0 in the future.,” he said. “Making MB stronger, longer, lighter, more compact, and quicker to set up will promote the development of infrastructure construction technology in general.”  

Smart motorway deals worth around £1.5bn have been awarded to some of the UK’s biggest contractors, with a Balfour Beatty/Vinci JV set to scoop the biggest of the packages.

Network Rail is set to spend up to £20m on an overhaul of its headquarters at Waterloo station.

The government’s decision to “pause” electrification on two major UK rail lines was made after Network Rail had provided “unreliable” and “not accurate” figures on the cost of its enhancement programme, according to transport secretary Patrick McLoughlin.

EDF Energy is on the verge of revealing “a number of preferred bidders” for work on the Hinkley Point C nuclear power plant.

Birmingham City Council has approved plans for one of the UK’s biggest regeneration programmes, including 4,000 new homes and a new High Speed 2 station.

Major contractors have signed an open letter urging the government to press ahead with Crossrail 2, after Sir Merrick Cockel was appointed to lead a growth commission on the scheme.

Contractors risk missing out on a major pipeline of work unless the government ensures its new roads fund is used to cover local roads, the MD of one of Britain’s largest highways contractors has said.

High Speed 2 has appointed Transport for London’s finance managing director Steve Allen as its new chief financial officer.
