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. The 2022 Building Safety Act established that dutyholders—owners and developers—of buildings like this should employ competent professionals. The challenge these dutyholders now face is to identify those professionals. The Engineering Council in the UK has established a means to do this, through the Higher Risk Buildings Register. In this episode, Chris O’Regan, chair of the joint ICE/IStructE committee that developed the register, explains the skills and expertise needed from engineers working on these structures. This goes beyond technical expertise: Chris highlights the need for empathy with residents, and a demonstrated ability to collaborate with professionals from other disciplines.

A wise asset owner builds on solid ground. Unless ground risks are clearly identified, projects can easily be delayed or delivered over budget. Some risks may not even be fully understood until an asset begins operations. In this final episode of three on ground risks and the asset life cycle, Karim Khalaf explains how one major European vehicle manufacturer only learned how the soil beneath their new manufacturing plant would act, once steel presses started working—effectively inducing a series of small earthquakes and setting foundations floating off the apparently solid sand they stood on. Assumptions about ground conditions can lead to costly and time-consuming emergencies during construction. An unexpected cavity, for example, may mean that work has to stop until the site is properly modelled. In the past, that could involve substantial costs and lengthy delays, as heavy geotechnical equipment is deployed. But, with the careful use of geophysical screening, answers can be delivered quickly, and work resumed, with costs kept under control. Rod Eddies describes how these two sets of techniques, namely broad geophysical screening and strategic geotechnical investigations, can be used together to create a detailed 3D model of the subsurface. This can be shared and used by those making strategic decisions, as well as by technical specialists and other stakeholders. Matt Waddicor of Fermi Development, who we heard from in the first episode, rounds up the advantages of using this approach throughout the asset life cycle, and shares how early investigations may support on time and on budget delivery, across the infrastructure sector.

Without a clear understanding of ground conditions, unquantified risk can be transferred from project owner to lead contractors when a contract is signed. In the first episode of this three part series, we explored how geophysical screening, using non-intrusive methods, can be used to reduce uncertainty in site selection and provide clarity on construction costs and delivery schedules. In this episode, we move past the final investment decision, to the development of project designs. Karim Khalaf, Regional Business Line Manager, Middle East, at Fugro, explains how one client commissioned a new method of site screening, ambient noise tomography, to check subsurface conditions before starting work on building a stormwater pumping station in Doha, Qatar. Not every project owner performs this sort of early geophysical investigation. However, as Rod Eddies explains, the Geo-Risk Management Framework can still be applied by lead contractors as they complete designs and schedule construction work. We learn how early screening can provide a basis for more detailed geotechnical techniques, using boreholes and cone penetration testing. This approach gives clients the answers they need, when they need them, while minimising the need to deploy heavy equipment.

On any project, uncertainty creates risk. Decisions that are made without a good understanding of site conditions can result in overengineering or threats to safety. Delivery may be delayed, and unexpected costs incurred. To avoid these risks, project owners and other stakeholders should question their assumptions and get real, actionable insights throughout the project lifecycle. In this three-part series, we explore a key source of risk to any project, subsurface conditions, and a new approach that builds certainty from the ground up. In this first episode, Rod Eddies, Solutions Director, Land, at Fugro, explains the development of the Geo-Risk Management Framework, a way of thinking about subsurface risks that builds on research on cognitive bias. We learn about GroundIQ®, a new approach to ground risk management that provides earlier, faster, and better site characterization. Early screening allows project developers to identify suitable sites and more accurately predict delivery times and costs before a final investment decision is made. Fermi Developments is a privately-funded nuclear developer, working to deliver ‘Ready to Build’ small modular reactor sites across the UK. The company recently formed a strategic partnership with Fugro, under which the geo-data specialists will support their work from site selection all the way through to delivery. In this episode, Fermi’s Matt Waddicor explains how this new approach to risk will help the developer identify suitable sites and prepare well-grounded proposals for investors.

Wastewater treatment is an overlooked lifesaver. While the medical advances of the last 100 years—penicillin, chemotherapy, and, more recently, mRNA vaccines—have transformed healthcare, keeping our water supplies free from pathogens like cholera and dysentery, has saved many more lives. The systems developed to treat wastewater are so successful that we can afford to flush and forget. But this is infrastructure we must not overlook. Growing populations, increased use by industry, and regulations that get tighter as we learn of new threats to human life and the environment, are putting wastewater treatment facilities under strain. Existing plants are often tucked away on constrained sites, and work as part of a sprawling network of sewage systems that make it extremely difficult for them to be relocated. This is very much the case at Ringsend in Dublin. Here, on a site bounded by other facilities and the sea, the waste produced by millions of Dubliners—and the city’s industry and commerce—must be processed before being discharged into the Liffey Estuary. To update the plant, its owners had considered building a 9km pipe to discharge waste outside of the sensitive areas of the estuary. But a new solution was identified. By implementing a novel form of biological treatment, developed by Haskoning, Egis was able to ensure that the effluent discharged was so clean, it would be safe for wildlife. But installing this would take careful planning and scheduling, in order to complete the work in tight constraints, without any pause in plant operations.
