Engineering Matters

Maintaining a tunnel requires many hours of dedicated work by highly skilled engineers. And as our network of tunnels expands, so does the maintenance demand. Asset owners and local authorities have been under pressure for years to find a cost-effective way of monitoring and maintaining their underground infrastructure. And now, engineers in Switzerland have turned to the complex structure of the...

Changes to the way we do design are coming; construction is languishing at the bottom of the productivity rankings, now below hunting and fishing.  Decision-making is happening late in the project lifecycle, meaning that design work has to be repeated unnecessarily, and a reward culture based on price rather than outcomes builds in more inefficiency. In this episode we look at the problems fa...

Remotely operated vehicles, uncrewed surface vessels and ever-increasing autonomy are removing personnel from dangerous work offshore in the North Sea and elsewhere.  Inspection of maritime assets is now being controlled from onshore operations centres. We look at one of these command and control centres, the Fugro facility in Aberdeen. With a robust regulatory framework and growing technological...

As a small island trading nation, Britain risks killing its economy and losing millions of jobs, unless it can allow people to get back to work in as normal a way as possible. So said John Holland-Kaye, CEO of Heathrow Airport, who wants to see a more sophisticated way of opening our borders. He was referring to the need to adapt to and live with Covid-19 for the foreseeable future. And part of th...

At the start of the Covid-19 lockdown, one of the few reasons people were allowed to leave their homes was to shop for the basic essentials.  Social distancing rules meant that shoppers were held in long queues that wound through supermarket car parks, moving slowly. One supermarket in northern England had the added problem of a car park resurfacing project that was underway, and anxious cust...

Manchester – the city has been on the cutting edge since the birth of the industrial revolution. From John Dalton’s Atomic Theory in 1803, to the invention of Graphene in 2004. More recently it has given the world the greatest music ever made. Home to 2.8 million people in 1.2 million dwellings over 500 square miles, Greater Manchester is the heart of the Northern Powerhouse and has a bigger econo...

When Dan Harmer received a call in March that told him to clear his schedule and prepare for a meeting, he knew it would be important, but had no idea quite what would be asked of him. With Covid-19 spreading exponentially, and the National Health Service looking increasingly vulnerable, he was the man chosen to build an emergency Nightingale hospital in Birmingham. The catch? He had less than two...

Hundreds of millions of people in the most economically disadvantaged places in the world spend up to 20 hours per week washing clothes by hand. This task, traditionally forced onto women, is back breaking and monotonous. Then in 2018 a promise made in a rural village in southern India has led Nav Sawhney to leave his dream job at a world-beating engineering company and launch an ethical start-up....

On 28 October 1971 the UK conducted its first and only successful orbital launch, firing the Prospero satellite into low earth orbit – LEO on a Black Arrow rocket. Since that time, the country has lacked a native launch vehicle. In this episode we speak with Joe Laynton, a mechanical engineer working for Skyrora, an Edinburgh-based company that aims to correct just that, and return launch ca...

Britain is emerging from some of the toughest social restrictions placed in peacetime history. As people come out of their homes, they are eager to meet friends and loved ones, and head back out into the world – but they are scared. To help keep people safe in a world gripped by Covid-19, and to adapt to the new behaviours of the population, episode partner Atkins (part of the SNC-Lavalin Group) h...

Engineers are in a uniquely powerful position. Able to shape our built environment and so influence the direction of civilisation, the impact that their expertise can have for the good of society and the environment is incredible. But people are human, and if a negative culture is allowed to thrive in the organisations that employ them, or if no attention is paid to understanding how problems are...

Since mid-2019, over 900 architectural practices in the UK have made a declaration of climate and biodiversity emergency, acknowledging the extreme seriousness of our situation and making a public commitment to positive change. Now joined by declarations from other disciplines in the construction industry, the growing movement needs coordination or it risks becoming siloed. In this episode we inte...

The coronavirus pandemic that has torn through society has also seen supplies of personal protective equipment (PPE) depleted at an alarming rate. As doctors and nurses are forced to improvise, and traditional suppliers struggle to meet the sudden increase in demand, help has arrived from an unexpected group of enthusiasts. The 3D printing community has come to the rescue. Thousands of volunteers...

Biodiversity in the UK is facing an emergency with around 30 percent of native species becoming extinct since the 1970s. This loss of wildlife, which echoes trends all over the world, could have catastrophic impacts on food, air quality and the environment. However for the UK change is on the horizon with a new Environment Bill seeking to reverse this with requirements for developers to deliver an...

How data from satellites can track structural movement, and give early warning of potential failure. New research shows that catastrophic bridge collapses could have been prevented if engineers had been paying attention to the right information, information that is currently being collected by satellites orbiting our planet. Satellite monitoring is one of the many innovations to come from the burg...

Carving out underground space for railways, roads, waterways, urban development and even fishing and farming is how some people spend their entire careers. One of those people is chair of the International Tunnelling Association Young Members Committee Keith Bannerman, who was obsessed by the industry from the moment he attended a short course in Brisbane and met “real rock star tunnellers”. These...

As cases of COVID 19 explode, the World Health Organisation is urging countries around the world to learn from South Korea. Before even recording its first case  of the virus its technology industries mobilised, enabling it to test anyone with symptoms, perform extensive contact tracing and isolate those at risk – fast. This enabled the country to protect its 51 million inhabitants as e...

How a new 2.5km cable pulled railway will connect Luton Airport’s terminal to the UK rail network boosting future growth. Today rail passengers arriving at the airport must disembark from the train and finish their journey on a shuttle bus. But not for much longer. Deep sheet piles are currently being driven into the ground to set out a cut and cover tunnel that will deliver a new rail link under...

The rapid and exponential spread of the new coronavirus, COVID 19 is changing the way that we live and work. First detected in December 2019 in Wuhan City, China, within three months it was a global pandemic. To keep operating through the crisis businesses turned to digital technologies to support home working. But this connectivity relied on infrastructure, from internet services to power supplie...

The UK has a legacy of 600,000 tonnes of nuclear waste being held in temporary storage facilities at 30 sites around the country. It is enough to fill a football stadium and despite over 60 years of generating nuclear power in the UK, we still don’t have a long-term plan for disposing of it. Scientific consensus is that deep geological burial of waste that has been contained in layer after layer o...

This winter a series of weather bombs detonated across the UK, overwhelming river systems and overtopping flood defences. River levels were off the charts, 4000 properties flooded, some temporary defences failed and people took to the streets in canoes. The UK is entering unchartered territory as far as flooding is concerned. Yet the threat of drought is not far away as climate change tells us tha...

How nematode worms, 3D printing and drones could revolutionise our approach to maintaining road surfaces. According to the RAC we are 1.5 times more likely to hit a pothole today than we were over a decade ago and winter is peak pothole time. In the cold months the UK’s road surfaces weather the impact of freezing conditions and the subsequent ground movement from thawing ice that goes on to creat...

An update on our Drones episode from January 2019 where we learn about new uses for unmanned aerial vehicles, and celebrate being shortlisted for three awards in the Publisher Podcast Awards held in London in March 2020. No-one knows how many penguins are in the Antarctic, and last year we discovered that thanks to the use of drones this is set to change, as scientists are using these unmanned aer...

A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years in 1930, the third billion in 30 years in 1960, the fourth billion in 15 years in 1974, and the fifth billion in only 13 years 1987. Growth rate hovers at a little over one per cent...

How new technology is supporting the UK’s offshore wind industry to bring down costs and accelerate construction. From new methods for drilling into the seabed, to advanced foundation design models and improved data capture, innovation is critical for this fast-growing market. But it won’t be easy. Deeper waters and variable ground conditions make these some of the most difficult construction proj...
