Engineering Matters

At the end of the Second World War, millions of tonnes of unwanted explosives and weapons were disposed of at sea. For decades, these dumped munitions lay hidden beneath the waves as time and tide passed over them. Now 80 years past that mass-dumping, corrosion has begun to expose the explosive chemicals inside these weapons casings. Lead, mercury and TNT breakdown products have begun to be detect...

In this Engineering Matters Awards episode, we celebrate the winners of the Health & Safety Champion category, which recognises engineers who are changing how we protect people in some of the world’s most challenging environments. Engineering is often measured by what we build: the bridges, tunnels, infrastructure, and systems that shape our world. But true engineering excellence is also defin...

This episode is part of the Engineering Matters Awards series, recognising individuals and organisations making an outstanding contribution to the engineering profession and wider society. Engineering is often judged by technical achievements: better products, more efficient processes, and breakthrough innovations. But some of the industry’s most meaningful contributions happen beyond the core aim...

For decades, infrastructure design has relied on ‘grey’ engineering: concrete flood walls, steel structures and rigid systems designed to control the environment. But with climate pressures intensifying, engineers are increasingly looking to work with nature rather than against it. This episode looks at the growing role of nature-based solutions in building climate-resilient infrastructure that ca...

In this special Engineering Matters Awards episode, we celebrate excellence across the industry, highlighting our Gold, Silver, and Bronze winners in the Diversity & Inclusion Champion category.  Engineering suffers from a ‘leaky pipe’ problem, where a great many potential professionals count themselves out of a career long before university. It is a problem that has been clearly identifi...

Greg Wilkes has seen the highs and lows of running a small business in the UK construction sector. From being talked into staying with his apprenticeship by his father as a young carpenter, to success, failed partnerships, and success again, he began to make it a point to note down everything he did that worked, and everything that did not. Now with a seven-step program, that in keeping with the b...

In this episode, we tell the story of MERMAID from the Wildlife Conservation Society, this year’s Engineering Matters Awards Environment Gold Champion. Emily Darling, director for coral reef conservation at WCS, describes why scientists need better ways of sharing coral data, and how MERMAID helps them do so. Rita Bento, a researcher at NYU Abu Dhabi joins the episode, in an interview recorded in...

Around the world, engineers are working to protect the environment. In this episode, we introduce eight companies who are taking steps to safeguard the natural world. All have been shortlisted for the Engineering Matters Awards. The first three shortlisted entries look at ways of understanding the natural world. Petra Ringeltaube explains how RWE’s SeaMi is taking a less invasive, ecosystems-based...

In its seventh Allocation Round the UK executed the largest offshore wind auction in European history, putting pen to paper on 8.4GW of new capacity, enough to power 10 million homes. Allocation Round 8 is expected to be even more ambitious, as the UK looks to upgrade its radar systems to enable a 10GW installation, according to Windtech International . Offshore wind projects require complete unde...

The London skyline is undergoing perhaps its most significant transformation in decades as a new ‘vertical renaissance’ is sending tremors of excitement from Guildhall to Mansion House. The City of London Corporation says that over half a million square metres of office space was granted planning permission in the City in 2025, equivalent to more than ten ‘Gherkins’ with around half of this amount...

Humanity’s furthest ever journey into space has been delayed. Again. An interruption to the flow of helium forced NASA to scrap the revised 6 March launch date of the Artemis II mission, and begin the slow process to roll the increasingly unfortunate rocket back to the vehicle assembly bay. While the delays are frustrating for the engineers involved, and space enthusiasts alike, every precaution h...

Systems thinking allows engineers to understand complex systems and the second-, third-, and nth-order effects of their interventions. It avoids the accidental creation of new problems when solving a first, and allows for the identification of effective leverage points for more impactful, sustainable change. The world, the built environment and our infrastructure all have patterns that can be unde...

Around the world, urban planners are seeking to deliver urban growth and increase access to city centres through the development of transit-oriented communities. These combine new publicly-backed transport infrastructure, with privately-financed residential and commercial development. It’s a route to more sustainable cities, but it involves careful navigation of budgetary constraints and the needs...

In the 1970s, Saudi Arabia, buoyed by a surge in oil prices, embarked on an ambitious building programme. The country moved rapidly to develop its cities and infrastructure. However, Prince Salman, then the governor of Riyadh, now the country’s King, saw that this was resulting in cities that were unmoored from their local context. This episode traces the evolution of modern architecture in Saudi...

For facade specialists, stone is highly prized for its performance and character. The right choice of stone can anchor a building in its local context, or make a striking statement. While stone has fallen out of use, modern approaches mean that it could now be used in the same standardised ways as steel, concrete and glass.  In this episode we learn that it is ripe for a return as a structura...

Sustainability experts often use a hierarchy to help their thinking about interventions. The best way to limit your impact is to do nothing at all. If that’s not possible, then use as few materials as you can. And finally, if extensive work must be conducted, then replace more carbon-intensive materials with those with less impacts. In this episode, Lucas Grisoni describes three projects in Paris...

Lifecycle carbon assessment – the process of monitoring the total carbon footprint of a structure from the first spade in the ground to demolition – sits at the confluence of engineering and sustainability. As we adapt our processes and understanding of the built environment, LCA is a critical measure to guide our decision making. The nature of the work is truly holistic, in winter an icy road mig...

Retrofitting is an instrumental step in reducing the carbon footprint of a city’s building stock. It also extends the life of a building and has a lower environmental impact than demolishing inefficient properties and building anew. Even a new development, such as the East Village in Stratford London, although just 12 years old, is still largely heated by fossil fuel. Adaptable designs are critica...

When you are designing a stadium for the World Cup, or any major sport, it’s vital to have a fan’s-eye view. For more than a century, the architects tasked with designing stadiums have used the C-value, developed by Victorian theatre designer John Russel. But this value just measures the view in one direction, towards the stage. Sporting events are viewed in the round, with fans all around the sta...

Nuclear power promises to provide energy when other sources can’t. But nuclear plants currently take a long time to build—often more than a decade. Anthony Burch, digital manager, Egis, and his colleagues, are working on the key components of Hinkley Point C in England. These form the so-called ‘nuclear island’—the reactor building and four associated safety buildings. In this episode, Anthony des...

At ITER, in France, scientists and engineers from around the world are working together to develop nuclear fusion at power plant scale. The project could one day lead to a world of truly abundant green energy.  In this episode, Caroline Dixon explains some of the logistical challenges of working on a project that is perhaps humanity’s largest ever experiment. In this decades-long project, the...

There is a changing view of the environment among public sector clients in the Middle East. Saudi Arabia has ambitious goals like generating 50% of electricity from renewables by 2030, the UAE has targets such as diverting 80 percent of its waste from landfill by by 2031, and Qatar is moving towards 100% treated wastewater reuse. With environmental considerations now at the core of new projects, r...

Lismore sits at the confluence of two rivers in New South Wales. Covering more than 1,300 square kilometres, it is home to more than 44,000 people. In 2022, it was hit by a huge flood, the highest on record, followed by a smaller, though still devastating, second flood. Five lives were lost in the disasters, along with 500 properties, making 2,000 people homeless at a cost of AUD 350M in damages.&...

Society needs to consider the impact of climate change on our cities because it is no longer a future challenge; it is a present reality. Cities with their concentrated populations, infrastructure and supply challenges are uniquely vulnerable to climate-related shocks, exposed to risks such as floods, heatwaves, water scarcity and any disruption to their systems. Engineers and decision-makers must...

Residents of tall buildings can face significant risks in the event of fire or structural failure. At Grenfell Tower in the UK, a fire in a resident’s kitchen spread rapidly around the building, due to failures in the testing and installation of cladding materials, and leading to widespread loss of life.  The inquiry into the fire revealed how overlooked risks can line up, causing disaster. T...
