Future Circular Collider conceptual design report submitted
22 January, 2019 Switzerland – Scientists and engineers at CERN have submitted the concept design report for the Future Circular Collider (FCC). This is a 100km-circumference particle-smashing machine that dwarfs the existing 30km Large Hadron Collider (LHC), and of course it will also need to be tunnelled.
  • DEP release Schoharie Reservoir update
    US – The New York City Department of Environmental Protection (DEP) provided an update to the Schoharie County Board of Supervisors on the USD 400M program to upgrade water supply infrastructure on January 18.
  • Hyperloop Challenge taken up in Britain
    Great Britain – The British Tunnelling Society (BTS) has formed a task force to take on the Hyperloop Challenge. Hyperloop is a rapid transit concept that involves propelling pressurised capsules down reduced-pressure tubes across great distances at enormous speeds. The challenge is to demonstrate a means to reduce the cost of tunnelling by a factor of ten or more, and so make the Hyperloop concept viable.
  • Algiers Metro TBM factory acceptance
    Algeria – A CREG TBM has undergone factory acceptance ahead of delivery to the Algiers Metro Extension project. The 10.5m-diameter EPBM will bore a the 9.5km from El Harrach Station to Houari Boumediene International Airport. The contractor is Seli Overseas.

Sequential excavation method tunnelling
20 December, 2018 Sequential excavation method (sem) is a type of tunnel design and construction that started to gain popularity in the 1960s and 1970s. The essential component of the SEM approach is to take advantage of the natural capacity and strength of surrounding geology to support the tunnel with minimum cost and time required.

Changing everything
22 January, 2019 I recently hosted a breakout session at a conference on ‘disruptive technologies’. These technologies were: the Internet of Things, Robotic Process Automation, Blockchain and Artificial Intelligence. It was interesting, and will be covered in a subsequent issue. But for tunnelling I can think of one historical change that was far more significant, which has recently been recognised with an award.
  • Goodwill to some, not all
    In what is possibly a nod to the season of good cheer, Ipsos Mori has published its annual veracity index. This poll by the market research company has the accolade of being the longest-running poll on trust in professions, having been taken consistently since 1983. The poll is simple; it asks respondents to say whether they trust different types of people to generally tell the truth.
  • Telling tales
    Every few months I have a meeting with the magazine’s Editorial Advisory Board, in which I ask their advice, plan future issues and weather some constructive criticism (this editorial will be reviewed at about 11.30am on 18 January 2019 – not that I am feeling self-conscious).
  • Half a Degree
    As T&T went to press the Intergovernmental Panel on Climate Change (IPCC), the UN body for assessing the science related to climate change, announced that limiting global warming to 1.5°C compared to 2°C would provide clear benefits to people and natural ecosystems, and goes hand in hand with ensuring a more sustainable and equitable society.
  • Science of the small
    It has been a while since I wrote about tunnelling efforts to further humanity’s understanding of particle physics.
