Retrofitting: the future of housing

This week, we’re going global. I’m joined by Jacob Mumm , General Manager for Public Infrastructure at Bechtel Corporation , to explore one of the most pressing questions of our time: how can the UK accelerate economic growth through smarter infrastructure investment? Have a listen here or find it on Apple, Spotify and Amazon et al of course! Jake brings three decades of frontline experience on complex, high-stakes projects around the world. From ageing transport systems to climate-resilient design, we dig into the real-world challenges that governments everywhere are facing - and the bold strategies that could turn them into opportunities. Issues discussed include: 🔹 The infrastructure funding gap 🔹 Political hurdles and project delays 🔹 Smart cities, green energy, and the digital future 🔹 How do we build faster, smarter, greener? 🔹 How do we cut through bureaucracy and actually deliver? 🔹 How can private sector players like Bechtel drive change If you're interested in the future of infrastructure - and what it will take to deliver systems that are resilient, sustainable, and future-proof - this is an episode you don’t want to miss.

What does it really take to design the world’s tallest, most iconic buildings - and what challenges lie ahead as cities grow ever taller? Well, engineering legend Kamran Moazami , Managing Director of Property & Buildings at WSP joins me on the latest episode of The Infrastructure Podcast , and he sure knows a thing or two! 🎧 Have a listen here: - or find it on Apple an Spotify et al, of course! With nearly 50 years of experience and landmark projects like The Shard, 22 Bishopsgate, and One Blackfriars under his belt, Kamran offers an unmatched perspective on the evolution of high-rise design. After all, he’s a Fellow of both the American Society of Civil Engineers and The Institution of Structural Engineers in London, and was awarded a Lifetime Achievement Award by the Association for Consultancy and Engineering (ACE) in January! From London to Dubai, New York to Shanghai, city skylines are rising fast. But height brings complexity—wind loading, vertical transportation, fire safety, and, critically, carbon and climate resilience. We also dig into how global events—from earthquakes in Southeast Asia to the legacy of Grenfell - are shaping public trust in high-rise development and impacting our ability to build. So whether you're an engineer, architect, planner, or simply fascinated by the future of our cities, this is one conversation you don’t want to miss.

Tackling Urban Flooding: The Case for Sponge Cities - excited to share the latest episode of The Infrastructure Podcast - this time with Lee Pitcher MP , Chair of the All-Party Parliamentary Group on Water, recorded live at the latest Twin Talks breakfast with Bentley Systems . Check it out here- or find it on Apple an Spotify et al, of course! The conversation dives into the urgent challenge of urban flooding and discuss the findings of a new white paper, "Creating Sponge Cities to Tackle Surface Water Flooding," produced by Bentley Systems and Aqua Consultants with support from British Water and, as a former water engineer with Jacobs and Yorkshire Water , Lee Pitcher, MP 💡 What’s the issue? As climate change intensifies and urbanisation accelerates, our outdated drainage systems are struggling to cope with extreme rainfall. The result? More frequent and severe pluvial flooding. 🌱 What’s the solution? The white paper outlines a bold strategy to rethink water management through sustainable drainage systems (SuDS), green infrastructure, and smart design - helping cities absorb, store, and manage water like a sponge. But if the solutions exist, why aren’t we embracing change faster? And how do we turn policy into action? Lee Pitcher has the answers. Catch the full conversation and feed your comments back to Lee and the APPG as he prepares to respond - and input to - the ongoing The Independent Water Commission, chaired by Sir Jon Cunliffe.

Potholes, potholes, potholes. Are we stuck in a never-ending cycle of road repairs? Or is a more fundamental solution required? As the 30th Annual ALARM Survey reveals, the state of local roads across England and Wales is worse than ever—with a staggering £16.81 billion backlog and over 34,600 miles in poor condition. Some shocking stats – so I spoke to David Giles , chair of the Asphalt Industry Alliance and director of Continental Bitumen to dig into the key findings of this year’s report and find out what’s stopping progress? Have a listen to the episode here . Once again, the ALARM survey begs the question - after 30 years what needs to change if we are to transform the condition of our vital local roads? Despite government pledges to fix millions of potholes each year, the reality is that short-term cash injections aren’t enough to halt the decline. But with local roads forming 97% of the UK’s network, isn’t it surely time for a long-term, sustainable investment strategy? A strategy that might help shift us from reactive patchwork fixes to a resilient, future-proofed road network.

The government published its long-awaited Planning and Infrastructure Bill last week – so who better to bring back to chat about it on The Infrastructure Podcast than UK infrastructure planning guru Robbie Owen , partner and head of infrastructure planning and government affairs at law firm Pinsent Masons . The Bill was heralded by government as providing “transformative reforms to get Britain building, tackle blockers and unleash billions in economic growth”. But will it really bring about that scale of change? Well to be honest, Robbie’s not totally convinced it goes far enough! Have a listen here . Lot’s to chew over - changes to infrastructure planning, environmental impact assessments, compulsory purchase powers; how can the planning system ensure that infrastructure projects not only proceed faster but also deliver better outcomes for communities and the environment? … and, as discussed with Robbie on the podcast before Christmas, new limits on the role of Judicial Reviews. But can these changes truly unlock growth, or are deeper structural issues being overlooked? Having interrupted Robbie’s visit to the MIPIM property event in the South of France sunshine last week, we cover a lot of ground. It’s a vitally important stuff and Robbie certainly, as always, brings it to life. Enjoy the episode.

I chose a quiet corner of the Royal Festival Hall to talk about embodied carbon with Adrian Campbell , founder of the Change Building consultancy and my go-to expert when it comes to reducing carbon across the infrastructure lifecycle. At least it was quiet when we started to record this week’s episode of The Infrastructure Podcast ! Apparently, weekday concerts are popular with schoolkids! Who’d have thought! No worries, any corner of this fabulous, brutalist concrete masterpiece on the South Bank is a great place to chat to Adrian about the need to understand, to think hard and to take action to reduce the embodied carbon in our modern infrastructure. It’s big and important stuff. Have a listen here and on Apple, Spotify, Amazon and all your favourite podcast hosts. As Adrian points out, the reality is that building fabric performance, building management systems and energy sources have all become much less carbon intensive over time as we have understood and assessed the carbon challenge. But less so for embodied carbon, meaning that is now the dominant source of emissions over the infrastructure life-cycle and to the obvious focus for designers’ attention. That starts with getting the next generation of engineers both fired up and informed. Hence Adrian’s new guide to assessing embodied carbon which he has just rolled out to his students at the University of Southampton . And a very useful and helpful little guide it has proved to be. Which got me thinking. Why shouldn’t every student have a look at it – every infrastructure professional for that matter? Well, to be honest, Adrian hasn’t actually published it formally yet. (But why not have a chat with him if you can help?) But he does explain it well in the podcast. So have a listen.

The UK government has set out bold and ambition plans to tackle the nation’s housing crisis. And as my guest on the The Infrastructure Podcast this week Anette Simpson , director of development and partnerships at Legal & General Affordable Homes points out, it needs them. Now! Have a listen here and on Apple, Spotify, Amazon and all your favourite podcast hosts. Because despite current targets to deliver 1.5 million new homes over the next five years, the reality is that we are still only seeing 50,000 to 60,000 affordable homes being built each year - far short of the estimated 145,000 required. That leaves a shortfall of over 1.3 million households on waiting lists, while rising costs, planning delays, and economic uncertainty continue to challenge the sector’s ability to tackle the crisis. Anette has passion and a plan to start to change all that. Her business is levering in private capital to support public cash and has a target to have more than 10,000 homes under management this year. Essentially, she aims to prove that, alongside the tradition public sector social housing providers, for-profit providers can – and must - play a crucial role in tackling the crisis. Have a listen. Creating homes for families is certainly up there as one the biggest infrastructure challenges facing the UK right now.

Seriously, I don’t know where the time has gone! But it’s the second anniversary of the The Infrastructure Podcast this week and my guest on episode 102 takes me back thirty years to the University of Southampton where I studied for my Degree in Civil Engineering. In this landmark episode I talk to the ever-fascinating Prof. Jeni Giambona, Associate Dean of Knowledge Exchange and Enterprise and a Member of the Centre for Resilient Socio-Technical Systems at the University of Southampton Business School. Jeni has worked at the sharp end of higher education and research for the last two decades and specialises in helping to link academia with industry and so drive investment in innovation as a key part of boosting the sector’s productivity and outcomes. Episode 102 is now live here and on Apple, Spotify, Amazon and all your favourite podcast hosts. Have a listen as we discuss: ⭐ Why embracing a systems approach is crucial; ⭐ The need to double down on collaboration and supply chain engagement; ⭐ Why investing in new data and digital technologies can help us to truly understand how infrastructure works. 🐶 And, of course, we hear why owning and training two 70kg Newfoundland dogs is a recommended, life changing experience.

Seven months ago, my guest on this week’s episode of The Infrastructure Podcast was working for construction giant Mace as a work winning director. Today Mike Reader is MP for Northampton South and chair of the All-Party Parliamentary Group on Infrastructure. That’s quite a change! Episode 101 is now live here and on Apple, Spotify, Amazon and all your favourite podcast hosts. As Mike explains, the government’s current focus on infrastructure delivery as the route to economic growth and improved living standards across the UK, makes Parliament and exciting place for a former civil engineer to be right now. And after last week’s conversation with Construction Minister Sarah Jones, this week’s episode provides an opportunity to hear the back bench viewpoint on the challenge of delivering the government’s bold infrastructure ambition. Quite often that means understanding how to realistically balance local community and constituency needs with the national priorities – not always easy but certainly doable, according to Mike. Have a listen as we discuss a range of issues including: ⭐ Dealing with the realities of life as MP ⭐ The role of the All-Party Parliamentary Group on Infrastructure ⭐ The supply chain’s role in supporting government’s growth ambition ⭐ Can the Planning and Infrastructure Bill transform our approach to delivery? ⭐ Is building 1.5M new homes in 5 years possible? ⭐ How can infrastructure professionals better understand politics? ⭐ What exactly is a Jack Tzu?
