Moorgate Station’s Facade At The New Entrance – 17th June 2022

These pictures show, the  new facade of the Moorgate station’s new entrance.

 

This entrance is in addition to the original entrance on Moorgate and it has stairs and lifts to the Circle, Hammersmith & City and Metropolitan Lines and a giant escalator and a lift to the Elizabeth Line.

It does look as though, the construction of the offices on top of the entrance is coming to a completion. Two escalators will be fitted in the space guarded by the green hoarding to give access to the offices and the walkways, that will lead to the Barbican.

HS2 Starts Work On First Pioneering ‘Green Tunnel’

The title of this post is the same as that of this press release on the High Speed Two web site.

These three paragraphs introduce the work at Chipping Warden.

HS2 today [Friday 10th June] announced the start of construction at the site of its first innovative ‘green tunnel’, designed to blend the high speed railway into the landscape and reduce disruption for communities.

Unlike a normal underground tunnel, the one-and-a-half mile (2.5km) Chipping Warden green tunnel in Northamptonshire is being built on the surface using a pioneering off-site manufacturing approach to speed up construction and improve efficiency.

This approach will see more than five thousand giant concrete tunnel segments made in a factory in Derbyshire before being assembled on site. The completed tunnel will then be covered by earth, with trees, shrubs and hedgerows planted to fit in with the surrounding countryside.

Note.

  1. High Speed Two are building five of these tunnels between London and Birmingham.
  2. I know from talking to engineers at Custom House station, which was also built in a factory, that the quality is excellent.
  3. But is it also cheaper and quicker, as all segments on the five tunnels are identical, no expensive tunnel boring machine is required and conventional equipment can be used?

These are some images from High Speed Two, which show the erection of the first segments of the green tunnel.

There is also this video, which shows more about the green tunnels.

I suspect we’re going to see a lot more of these tunnels.

The Story Behind The Concrete Panels On The Elizabeth Line.

These are a selection of the pictures I took yesterday inside Elizabeth Line stations.

Note.

  1. The walls and ceilings appear to be covered in light grey panels with holes.
  2. The material appears to look like concrete.
  3. Every one is a totally different shape, so how were they manufactured?

This article on Ian Visits is entitled How Crossrail Is Using 3D-Printing To Build Its Stations.

This is the two opening paragraphs.

When you start to use the new Elizabeth line stations, among its many achievements will be the first large scale use of 3D-printing in concrete.

The use of 3D printing has made possible one of the more distinctive features of the future Elizabeth line stations — the curved concrete panels that will line the inside of the passenger tunnels and some stations, and sinuously glide around corners in a way never seen before in a tube station.

There will be a total of something like 36,000 of these panels and although printing each in concrete is possible, Crossrail would probably have been delivered in the 2040s or 2050s.

The contractors used an innovative process called FreeFAB, which had been invented by an Australian architect.

  • The process creates a wax mould for each panel using 3D printing.
  • This mould is then used to create the actual panel.
  • After each panel is cast, the wax is melted off and recycled.
  • The panels are made in a factory in Doncaster.

We will see a lot more of this technique used in the construction industry.

This Company Does What It Says In The Name

I took these pictures on Tottenham Court Road.

This is a Google Streetview from a few months ago.

I don’t think it will be missed. But it looks like another Crossrail related redevelopment.

One Broadgate – 9th April 2022

I haven’t walked down Eldon Street for some time from Moorgate to Liverpool Street station and last time, there was an office block on the North side of the street.

Note.

  1. Yesterday, there was just a large hole there, which will be filled by the new development of One Broadgate.
  2. The silver building in the background of many of these pictures is 5 Broadgate, which is the London offices of UBS.
  3. One Broadgate will be a ten story development.
  4. The development will be a mixed development with retail and leisure on the lower floors and offices above.
  5. The last three pictures show the developing plaza in front of Broadgate, with another new development in the South-West corner.

Despite Brexit, the Covid-19 pandemic and now the Russian attack on Ukraine, there seems to be no letup in the building of new offices in London.

The Crossrail Article That Everyone Must Read

This article on Ian Visits is entitled A Sneak Preview Of London’s New Elizabeth Line Railway.

As the title of this post indicates, Ian’s article is very much a must read and it gives everybody something worthwhile to look forward to, after what has been the worst two years of many peoples’ lives.

The Crossrail Opening Date

There are a few more tests to do and Ian says the line could open a few weeks after Easter. With the Bank station upgrade apparently going well as I reported in Final Tunnelling Gets Underway On Bank Station Blockade and likely to open in mid-May, I wonder if TfL would prefer that the two projects opened at different times for management and operational reasons.

Easter is the 17th of April, and two weeks later is May Day, with the Bank Holiday on the Monday.

If they can do all the tests, there would be good reasons to open Crossrail on the first of May.

  • It’s a different day to the opening of the Bank station upgrade.
  • They would have two clear days to get Crossrail open.
  • A lot of people will be going to Central London.
  • Other Mayors would have organised a party.
  • A Bank Holiday would give the new infrastructure a proper test with real passengers and lots of children.
  • Crossrail could also help to cover for a late-opening Bank Station Upgrade.

If I needed to bet on it, my money would be on an opening on Sunday, the first of May.

The Bakerloo Line Link At Paddington Station

Ian writes this interesting paragraph.

Something though that was added to Paddington station after the funding was approved was a new direct deep tunnel link from the platforms to the Bakerloo line. London Underground contractors built the link, and Andy Lord suggested that they are considering opening up the link before the Elizabeth line opens fully as it would help with offering step-free access for Bakerloo line customers.

Many people find getting to Paddington difficult, as I do from Dalston.

I typically use some roundabout and slow routes and most end up with arriving at Paddington on the Bakerloo Line.

Opening the link early would have the following effects.

  • It would make things a lot easier for me and probably many other passengers.
  • It would add passengers to London’s least-used Underground line.
  • It would add capacity to the Bakerloo Line station at Paddington.

It would also give a piece of the infrastructure, a good soak testing with real passengers and may flag up some changes that needed to be made to details like signage.

Opening The Liverpool Street and Moorgate Pedestrian Link

In London’s First Underground Roller Coaster, I described this link, which I believe will be used by more than just rail passengers.

I feel that like the Bakerloo Line Link at Paddington station, that this link could be opened early.

Conclusion

I can’t wait for Crossrail to open.

Earth Friendly Concrete

I was alerted to this product by this article on New Civil Engineer, which is entitled Keltbray Saves Carbon And Money With Earth Friendly Concrete On East London Job.

The article gave enough clues to find the Earth Friendly Concrete home page.

This is the introduction on the page.

We want to have a positive impact on the environment and supply our customers with an excellent product, that is why we created Earth Friendly Concrete ® by Wagners. It is a concrete that uses no ordinary Portland cement, instead using a geopolymer binder system made from the chemical activation of two industrial waste by-products – blast furnace slag (waste from iron production) and fly ash (waste from coal fired power generation). Our product has ZERO Portland cement and it has a much lower embodied energy compared to ordinary concrete, saving 250kg of CO2 for every cubic metre poured. Importantly, the engineering and construction properties of this environmentally friendly concrete is, in some areas, better than normal concrete. EFC has some significant performance advantages over normal Portland cement concrete, including improved durability, lower shrinkage, earlier strength gain, higher flexural tensile strength and increased fire resistance.

On this page, which is entitled About EFC, this said about the products Environmental Excellence.

EFC is a new class of concrete that contains NO ordinary Cement. Globally, the production of 1 tonne of Portland Cement produces 1 tonne of CO₂ emissions and is responsible for 5 to 8% of manmade greenhouse gas emissions. Instead of cement, EFC has a geopolymer binder that is made from the chemical activation of two recycled industrial wastes, flyash and slag. This recycled binder reduces the CO₂ emissions associated with Portland cement by 80 to 90%.

Every m3 of 40 MPa EFC saves 220kg CO₂ emissions.

Wagners, the company behind the development, are based in Queensland. Australia.

So it’s a case of Well Done The Aussies!

They have appointed Capital Concrete, to deliver Earth Friendly Concrete in the London area.

Conclusion

Does High Speed Two and other large projects that will need large amounts of concrete, know about this development?

Tideway – Blackfriars Bridge Foreshore – 13th February 2022

I took these pictures of the Tideway’s Blackfriars Bridge Foreshore site from the top of a 63 bus on Blackfriars Bridge.

Compare the pictures with those I took on the 4th September 2021.

HS2 To Trial New Building Method Which Could Provide Carbon-Free Energy

The title of this post, is the same as that of this article on Rail Technology Magazine.

This is the first three paragraphs.

Part of HS2’s Innovation programme, an HS2 building site in London is to become a test bed for a new building method which could ultimately provide carbon-free energy to stations on the new high speed route.

The new approach will be trialled by contractors Mace Dragados at the project’s Euston station site in London and will draw ground heat up through the foundations of a newly-built construction site office.

Developed by Keltbray, the innovative new technology is estimated to harness enough energy to supply 80% of the building’s heating and hot water needs.

It’s an incredibly simple, but extremely powerful idea, that revolutionises heating, cooling and hot water in buildings.

Read the article and then read the brochure on the Keltbray web site.
