The world is facing a pandemic and many individuals are struggling with their daily lives as a result.
From a historical perspective, there is nothing new about adversity. My book ‘Building Passions‘ includes some examples in the past.
Isambard Kingdom Brunel was almost killed in 1828 when the Thames Tunnel collapsed during construction and flooded the works nearly drowning him. He spent many months regaining his health after a serious injury to his leg. It was a frustrating time for him, but once he had recovered he went on to design the Clifton Suspension Bridge in Bristol, his first epic structure.
Augustus Welbin Pugin was a highly talented young designer who was used by Sir Charles Barry to create the beautiful Gothic-style decoration of the New Palace of Westminster. His health suffered fatally from the exertions he placed on himself to meet deadlines for his many demanding clients. Charles Barry followed him for the same reasons, though considerably older, in 1860.
In 1879 a train crossed the Tay Bridge in Scotland in the middle of a huge storm. Unknown to the passengers, the iron structure supporting the track had undergone immense stress due to the wind and waves. Suddenly, the bridge collapsed causing the engine and coaches to fall into the estuary. Many lives were lost and the famous bridge engineer never recovered from the damage to his reputation – more positively, the resulting inquest led to sturdier bridge-building, exemplified by the vast steel structure of the Forth Rail Bridge also in Scotland. Sir William Arrol supplied the improved version of iron for that project, as well as for Tower Bridge in London, completed four years later.
Loch Etive is a Scottish sea inlet or fjord north of Oban in the Highlands.
Back in the 19th Century it was decided to extend the railway from Oban northwards and the big issue was whether to go round Loch Etive or across it. Unlike other lochs it had a shallow part at a place called ‘The Falls of Lora’. The name was apt as when the tide comes out of the loch it produces a standing torrent of water.
The engineers (John Wolfe Barry and partners) knew it would be too difficult to place any part of a bridge directly in that part of the loch, so needed to come up with a different, not too expensive solution for the trains to cross. They decided on a single span cantilever action bridge made from steel.
What is a cantilever bridge? The most famous example then and still with us is the Forth Rail Bridge, also in Scotland, for which the huge amounts of steel were supplied, like at Loch Etive and Tower Bridge, by William Arrol and Company of Glasgow.
The Forth Rail Bridge was over-specified due to the high winds in the wide sea estuary where it was located – by contrast the bridge over Loch Etive would shorter and could be based on a simpler design, but using the same cantilever principle. The rising bascule leaves on Tower Bridge also acted as movable cantilevers, extending out from the tower bases to meet in the middle of the River Thames.
When the Connel Ferry Bridge was completed in 1903, it became the world’s longest single span cantilever bridge (the Forth Rail Bridge had double spans!). It was soon taken over by other bridges, but I feel it set a precedent and it is still with us now for road traffic only.
This is the first post in a series of 10 favourite structures featured in the book ‘Building Passions’ by Nick von Behr. The 11th post will try to rank the structures in order of appeal.
I gave a STEM engagement lecture yesterday at Canterbury Christchurch University in England about my book ‘Building Passions‘.
As part of the promotion for the lecture, I had run a week long Twitter poll on four structures mentioned in the book.
All of these were built in London during the reign of Queen Victoria but, more importantly, the ‘builders’ were the key architects and engineers covered by the book.
At the lecture an audience member asked me why I had chosen those four structures and I tried to explain, but ended up saying it was purely subjective.
In fact I will now produce a list of my top 10 structures from the book, including those four, and in subsequent blogs justify why I have selected them. I will also try to rank them and, who knows, may makes some changes along the way!
Houses of Parliament
SS Great Eastern
Connel Ferry Bridge
Royal Opera House and Floral Hall
How did I produce this list?
The main rule applied was using enough different types of structures, associated with the main architects and engineers covered in the book. The commonality was that they were either a Brunel or a Barry, or both. I could have made it a longer list and changed every one of the structures, so that’s where the subjectivity comes in. The full list is available (with many hyperlinks) at: https://www.buildingpassions.co.uk/sway-of-structures.php
I will start the series of blogs with a less well-known structure, the Connel Ferry Bridge in Scotland. The first clue is that it was built by Sir John Wolfe Barry and Partners in 1903.
I created the list for indexing purposes, as it naturally flowed out of my text for the book. Perhaps I should have done it the other way round?
All lists need choices to be made. The public voted Isambard Kingdom Brunel the second greatest Briton after Churchill. Does that make his structures the best British ones ever? Of course not!
This website focuses on the works of his son Henry Brunel in partnership with Sir John Wolfe Barry, who really gets the credit as project lead. His father Sir Charles Barry has many buildings on the list, including the Houses of Parliament, but no tunnels, bridges, docks or rail lines and stations. Sir Charles was an architect, unlike the previously named engineers.
Other architects and engineers are on the list, as well as unattributed structures such as the Acropolis or the Burj Khalifa.
Some might say it’s a bit of a dog’s breakfast. I disagree. There are connections between all these structures across and over time.
Which is my favourite structure on the list? No surprise to those who know me, it’s the Travellers Club in London by Charles Barry and his close friend John Lewis Wolfe. Apart from sheer admiration of form and function, my father used to be a member and often stayed there on trips from Switzerland to the UK.
I also appreciate the significance of John Wolfe.
Sir Charles’s fourth son was named after him, and in tribute to his memory and lineage, he continued with the ‘Wolfe’ title in a family name that is still alive today.
On 30 June 2019 London and possibly the world will celebrate a day that commemorates 125 years since the opening of a well-known bridge.
No, not the Brooklyn Bridge in New York, opened in 1883, nor the Forth Railway Bridge in Scotland opened in 1890, though both deserve special mention for their uniqueness as huge structures, still in use, which employed steel in a ground-breaking way.
Not everyone knows that the two famous towers which encapsulate the bridge are also made from steel. It is the same Scottish steel used to build the Forth Bridge first, and then almost immediately shipped down to London for the next big project.
In the case of Tower Bridge, the steel framework was clad in stone, which while acting to protect it from corrosion, was also needed to meet the architectural requirement that the bridge blend with the medieval Tower of London next to it. There was much controversy at the time about this.
The enormous bascule leaves, which still open and shut for river traffic, were a wonder to behold for the royals and public who attended the opening ceremony and were only surpassed in length a few decades later in the United States. I write about them in my forthcoming book on Sir John Wolfe Barry and Henry Brunel (the civil engineers for the bridge), which will also cover their famous fathers Isambard Kingdom Brunel and Sir Charles Barry.
Footnote: Dan Cruikshank, the TV broadcaster specialising in architectural history, has presented programmes on Tower Bridge which are sadly no longer available via broadcast networks. But for an intro to the history of London’s bridges see: https://www.youtube.com/watch?v=8n15w-s1qIM. Tower Bridge itself start from 47:30 minutes in.
I’ve had the privilege of working with leading civil and structural engineers over the period since early 2016.
I am not one of them, in the sense that I don’t have their knowledge, understanding and skills in the technical requirements of civil and structural engineering. However, I do understand much better some of their key attributes and motivations.
One that stands out is their approach to solving problems. If a building or a bridge falls down killing and injuring people then the first question asked is: who built it? There may be some context for this, in the sense that if the structural failure was due to an ‘Act of God’ such as an earthquake or tidal wave, then some leeway is given to the identified responsible person. However, if as in the Grenfell Tower inferno, or the collapse of the Morandi Bridge in Genoa, there is some sense that the blame was entirely linked to human neglect, then the repercussions can be very severe for those found wanting.
On the other hand, progress through technical advances is only really made as a response to a crisis of some kind. If we had no crises then life might appear easier for all of us, but there would be costly consequences. Society would become stale and complacent, more susceptible to potential threats that could have much bigger impacts for larger numbers of victims. There are difficult choices to be made with pros and cons each way.
Civil and structural engineers therefore solve problems as ‘scientifically’ as they can, based on hard evidence of past failures and successes, but also with due acknowledgement to present circumstances and future possibilities. The professional standards they set for themselves assure that this is the case, and if the public is not sufficiently convinced then Government legislates as a further safeguard.
The 19th Century Barrys, about whom I am currently writing, faced these same issues as builders of structures. They also tried to guide the conversation through their involvement with developing professional bodies in architecture and civil engineering. Charles Barry junior and John Wolfe Barry were both Presidents of their Institutions (RIBA and ICE) and Sir Charles Barry won a preeminent Royal Gold Medal from Queen Victoria for his professional services to architecture.
