National Grid’s London Power Tunnels Breakthrough Completes £1 Billion Project’s Tunnelling Activity
The title of this post, is the same as that of this press release from National Grid.
These bullet points sum up the press release.
- Landmark moment for London Power Tunnels project as 140-tonne boring machine emerges at Eltham site following final subterranean journey
- Breakthrough marks the completion of 32.5km of tunnelling at depths of up to 60m under seven South London boroughs
- Due for completion in 2026, the project is rewiring the capital’s electricity network to boost resilience and future-proof supplies as demand grows
This is the seventh major tunnel in London in recent years to be completed.
- Elstree and St. John’s Wood Cable Tunnel – Electricity – 12 miles – 2005
- Lower Lea Valley Cable Tunnels – Electricity – 3.7 miles – 2008
- Lee Tunnel – Sewage – 4.3 miles – 2016
- New Cross and Finsbury Market Cable Tunnel – Electricity – 3.5 miles – 2017
- Northern Line Extension To Battersea – Rail – 2 miles – 2021
- Elizabeth Line – Rail – 26 miles – 2022
- Silvertown Tunnel – Road – 1 mile – Under Construction
- Thames Tideway Tunnel – Sewage – 16 miles – Under Construction
- Euston Tunnel – Rail – 4.5 miles – Under Construction
Note.
- It is likely that there will be CrossRail 2 and an extension to the Bakerloo Line.
- It certainly seems to have been a prudent decision to create Tunneling and Underground Construction Academy or TUCA to train more tunnellers, before the Elizabeth Line was built.
But I don’t believe that will be all the large tunnels that will be built in the capital.
Elizabeth Line: More Than 100 Million Journeys On Elizabeth Line, Says YouGov
The title of this post, is the same as that of this article on the BBC.
These three paragraphs introduce the article.
More than 100 million journeys have been made on London Underground’s new Elizabeth Line since it opened last May, according to a survey.
The YouGov poll suggested 45% of the capital’s residents had also used the line from Reading, Berkshire, to Abbey Wood and Shenfield in Essex.
Transport for London (TfL) said on 1 February it had completed about 600,000 daily journeys.
That is all well and good, but to me, this is the most significant paragraph.
TfL said the railway was “on track to break even” based on operating costs by the end of the 2023/24 financial year.
So it looks like that the planners got the modelling of the operation of the railway correct.
From my experience of project management, I believe that the Elizabeth Line project could have been considered as five main projects.
- The boring of the Central Tunnel
- The updating of the existing branches to Abbey Wood, Heathrow, Reading and Shenfield
- The building of the Class 345 trains
- The signalling
- The fitting out of the stations in the Central Tunnel
Delivery though was a bit patchy!
These are my thoughts on each sub-project.
The Boring Of The Central Tunnel
I was told, that early on, it was realised by the contractors that they didn’t have enough workers, who were certified to work underground.
So the Tunneling and Underground Construction Academy or TUCA in Ilford, was built to train more workers.
This helped the Central Tunnel to be completed on time.
Since then, two more tunnels; the Thames Tideway and the London Power Tunnel have been successfully completed on time and on budget, thus vindicating the building of TUCA.
The Updating Of The Existing Branches To Abbey Wood, Heathrow, Reading and Shenfield
There were a few hiccups, but generally the branches were updated and were operating into Paddington and Shenfield before the line opened.
The Building Of The Class 345 Trains
This wasn’t perfect and Bombardier’s financial state didn’t help, but the trains had good tests running out of Liverpool Street and Paddington.
The Signalling
A lot of commentators have said the signalling was too complicated. But eventually, it all seems to be working.
Was enough testing done away from the Elizabeth Line?
My feeling is that a new UK test track should have been built in the early 2010s, so that some testing could have been done professionally away from London.
The Fitting Out Of The Stations In The Central Tunnel
This was certainly a cause of late handover of stations like Bond Street, Farringdon, Whitechapel and others.
I heard tales, where other projects in London, were offering more money, so consequently workers were moving with the money, thus delaying the completion of stations.
I certainly heard a tale, where all the electricians on one station project moved en masse to complete the new Tottenham Hotspur stadium.
Some of the projects were office projects, paid for by sovereign wealth funds with bottomless projects, so they could make sure their project finished on time.
There were also the problems caused by Brexit, the pandemic and major projects running late in Germany and Europe.
It is my view that Elizabeth Line should have been given more priority, by delaying commercial projects, so that the pool of available labour wasn’t exhausted.
Some of the forest of projects around Elizabeth Line stations, should have been given planning permission, that meant they couldn’t start until Elizabeth Line was finished.
In the 1960s, there was certainly a similar labour problem in Aberdeen. I was told, that the oil majors, who nearly all used the project management system; Artemis, that I had written, talked to each other to make sure the situation didn’t get any worse.
I wonder, if someone was watching the labour shortage problems in City Hall?
Conclusion
I believe that if Elizabeth Line had been given the priority it should have been, that it would have been opened earlier and just as it is now, it would be showing a sensible cash flow.
Now it is a question of catching up financially.
Crossrail: Report Finds Not Enough Money To Finish Project
The title of this post, is the same as that of this article on the BBC.
These are the first two paragraphs.
The cost of completing Crossrail exceeds available funding, the government spending watchdog has found.
The National Audit Office (NAO) estimates the cost of the new rail link will be between £30m and £218m above the current funding.
After such a good start with the tunneling and surface line going well, how did we get here?
My main business for nearly forty years was writing project management software and that gave me a deep insight into the dynamics and mathematics of large projects.
The software, I created in the 1970s; Artemis was deeply involved in the most important project of the time; North Sea Oil.
But then more by luck, than any judgement on my part, it was well suited to solving the management problems of North Sea Oil.
The software ran on a small Hewlett-Packard mini-computer with an attached display and a printer, whose footprint, gave Artemis an advantage over competitors who needed a mainframe, for which there was no office space in Aberdeen.
I had first got involved in scheduling resources at ICI about five years earlier and because from previous experience I knew resources would be critical, I gave the program extensive resource aggregation and scheduling capabilities.
I have been told that the latter proved invaluable in successfully developing North Sea Oil. People may have been flattering me, but I do know that Shell used to ensure that all their suppliers used Artemis, so they could check easily if they were being told the truth.
I suspect that Shell and others used the aggregation capability to see that they weren’t overloading the pool of available labour.
Artemis definitely proved itself capable of handling the various projects in the North Sea.
We have now moved on forty years, but has project management moved on to cope with the advances in technology of the modern world?
As with North Sea Oil in Aberdeen, in the 1970s, Crossrail and other large projects like Berlin’s new Brandenburg Airport will always have a need for large numbers of resources, be they men, materiel or machines.
I have some questions.
- Do all contractors working on Crossrail use the same software?
- Does Crossrail have the right to inspect the contractors project management systems?
- Is the upward reporting what it needs to be?
- Does the software the contractors use, have an aggregation capability?
- Do Crossrail track and predict the resources needed?
Someone I respect told me, that a lot of modern project management software doesn’t even have an aggregation capability- Enough said!
I must admit, aggregation and scheduling software is difficult to write, so it might be easier to cut it out and let your clients muddle through!
But The Tunnels Were Built On Time And On Budget!
It all started so well, with the first part of the project, which was the boring of the tunnels being completed on time and on budget.
Observing the project, as I did and picking up information from engineers working on the tunnels and various magazines and television programs, I have to come to the conclusion, that the credit for the on time and budget completion must be down to excellent planning.
- I don’t remember any delays or problems reported in the tunneling. Was that good planning and surveying or luck?
- There were few if any articles on the BBC or in the Standard complaining about the problems the tunneling was inflicting on Londoners.
- The planners realised there could be a shortage of workers qualified to work underground, so they built the Tunnelling and Underground Construction Academy at Ilford, which I wrote about in Open House – TUCA.
Certainly, St Barbara, who is the patron saint of tunnellers looked after the project and its builders.
Worsening The Resource Problem
Crossrail, the Greater London Authority and the Boroughs should have been monitoring this growing resource problem, but I doubt they were in anything other than a perfunctory way!
Instead the politicians were giving planning permission to anybody with money, who wanted to build a shiny new development close to a station.
These projects would need more men, materiel or machines.
As many of these new developments are backed by companies or funds with bottomless pockets to get their developments finished they were prepared to pay more for their labour.
So labour has been deserting Crossrail in droves, thus further delaying the project.
Senior politicians in the Greater London Authority and the boroughs should accept some responsibility for Crossrail’s delay.
They didn’t need to withhold the planning permission, just say that construction of the other projects couldn’t commence until an appropriate phase of Crossrail was open.
In some parts of the world, brown envelopes will have changed hands, but it would be nice to know how many mayors and senior politicians have had holidays in places, they would not normally visit.
Senior project managers tell me, that they would not be surprised if developments along Crossrail had delayed the project.
The Covid Problem
No-one saw Covid coming, except possibly the Chinese.
But good project management is all about negotiating the slings and arrows of outrageous fortune.
There is the story of the miniMetro production line.
The first body shells coming out of the automated welder were crooked and it turned out that the machine had hit a motorway bridge in Germany. But by good project management using Artemis, British Leyland engineers were able to get the second line working correctly before the first and the car was launched on time.
With Covid, the Mayor shut construction, and it was some months before it restarted again.
I am certain, that with good project management we could have done better.
Covid is also a good excuse for lateness.
On the other hand good project management got the vaccines developed, manufactured and delivered into arms.
Covid also blew a big hole in Transport for London’s finances.
But then so did Sadiq Khan’s Fare Freeze, that brought him to office.
Could Crossrail Have Part-Opened Earlier?
I often ponder this and others ask me if it would be possible.
The Victoria Line was built with crossovers and it was able to open in phases.
Crossrail has crossovers in the following places.
- Either side of Custom House station
- To the West of Whitechapel station
- Between Farringdon and Tottenham Court Road stations
Note.
- It doesn’t appear to have been built for part opening.
- From media reports, it appears Whitechapel station is the basket case in the East.
The answer is probably that Crossrail can’t be part-opened, but there are good reasons, why it should be opened earlier.
- To generate a small amount of revenue.
- To give travellers and Londoners in general a lift.
The only practical service would be a few trains turning at Farringdon.
Conclusion
I blame politicians for Crossrail being late and over budget.
Open House – TUCA
I went to the Tunnelling and Underground Construction Academy at Ilford.
It is an impressive place, that trains workers and prospective ones in the skills needed to work underground.
It is actually the first legacy of CrossRail, as they will be needing substantial numbers of workers over the next few years.
