HS2 Reveals Images Of First Landscaped ‘Green Tunnels’ For Bucks And Northants

The title of this post, is the same as this press release from High Speed Two.

This image shows one of the proposed tunnels.

The article explains the design and describes how the tunnels will be built in a factory in Derbyshire and assembled on site.

Off-site concrete construction was used at Custom House station on Crossrail. I wrote about the construction of this station in An Express Station.

The picture shows Custom House station under construction. One of the engineers told me, that the quality of the concrete in the station, is so much better than normal.

Will Some Of The New Buildings For Heathrow Be Built In Scotland?

It’s all explained in this article on the Offsite Hub website, which is entitled Heathrow To Offer Offsite Hubs To Other Mega Projects.

This is the first two paragrahs.

Airport says schemes such as HS2 and Hinkley could make use of planned offsite manufacturing hubs

Heathrow Airport has said it hopes its idea for a series of offsite manufacturing hubs to help with its £16bn expansion plans will be used by other major projects, including the new nuclear power station at Hinkley and the HS2 railway.

Sounds a good idea to me.

A few other points.

  • Offsite accounts for 10% of the construction industry.
  • Heathrow are aiming for between 25% and 40%.
  • It will reduce the peak on-site workforce at Heathrow.
  • Offsite was safer, cleaner and less weather dependent.
  • Four hubs are plans, with one definitely in Scxotland.

A few months ago I talked to one of the managers building Custom House station, which was largely built offsite in Sheffield.

He told me, that the quality was so much better, than if it had been built traditionally.

The quality certainly wasn’t traditional pre-fab either.

Could this be part of the solution to our housing crisis?
