Climate Adaptation and Resilience in Foundation Engineering

Climate change is creating new risks for foundation and geotechnical engineering. More frequent extreme rainfall, flooding, rising sea levels, changing groundwater conditions and heat events can affect both the design life of infrastructure and the way construction projects are delivered. In response, the European Federation of Foundation Contractors and the Deep Foundations Institute have developed the Climate Adaptation and Resilience Guide as a practical resource for the geotechnical sector. 

The guide distinguishes climate adaptation from climate mitigation. Mitigation seeks to reduce greenhouse-gas emissions, while adaptation focuses on preparing infrastructure, organisations and construction processes for the consequences of a changing climate. For piling and deep-foundation projects, this means considering future conditions when assessing flooding, scour, groundwater fluctuations, extreme loads and access to construction sites. 

The publication presents climate resilience as the ability of a project or system to withstand climate-related hazards, adapt to changing conditions and recover after disruption. This perspective is particularly important for bridges, ports, quay walls, retaining structures, coastal infrastructure and foundations constructed in areas exposed to erosion or rising water levels. A foundation designed only for current conditions may not provide sufficient reliability over its intended service life. 

The guide proposes a practical “What, Why, How and Measure” framework. The first step is to identify the climate-related issue and understand how it affects geotechnical work. The second is to assess why the issue matters, including its consequences for design, regulation, cost, programme and business continuity. The third step is to introduce appropriate actions, while the final step is to measure performance and review whether the selected measures are effective. 

For designers, adaptation may involve using updated climate projections, assessing future groundwater levels, allowing for increased hydraulic or scour loads and considering more severe combinations of environmental actions. For contractors, it may require revising construction sequences, protecting working platforms, improving drainage, planning for extreme weather interruptions and ensuring that piling rigs, cranes and support equipment can operate safely under changing site conditions. 

The guide also highlights the value of monitoring and early-warning systems. Instruments can be used to track groundwater, pore pressure, settlement, erosion, temperature, structural movement and other indicators relevant to foundation performance. Monitoring allows project teams to identify developing risks and, where appropriate, adjust construction methods or maintenance plans before a failure occurs. 

Nature-based and flexible solutions are presented as possible elements of a resilient strategy. Water-retention measures, restored natural barriers, improved drainage and adaptable layouts may reduce exposure to flooding and erosion. Such approaches do not replace sound geotechnical design, but they can work alongside deep foundations and engineered retaining systems to improve the resilience of the wider project. 

The central message for the piling industry is that climate resilience should be considered throughout the project lifecycle—from site investigation and equipment planning to construction, monitoring, maintenance and eventual refurbishment. The EFFC/DFI Guide is not a mandatory standard; it is a practical framework intended to help designers, contractors and project owners make foundation systems more adaptable and reliable under future climate conditions.
