Invited Lecture: How designers are reinventing the future?-PPT Presentation

PPT Presentation

Pdf Summary

The presentation argues that the piling and geotechnical industry must respond to the climate and wider environmental crisis by reducing emissions while contributing to resilience, biodiversity and healthier soils. The transition is driven by time-bound carbon targets, client and policy requirements, Scope 3 reporting, financing criteria and pressure on technology and material supply chains.

The central approach is to <strong>avoid, improve and switch</strong>. Avoid unnecessary foundations through better design, reuse existing assets, reconsider pilecaps and use risk-based design supported by monitoring. Improve construction through efficient logistics, temporary works and equipment, alongside electrification and lower-carbon materials. These options are developing, but none is a universal solution: electric equipment has limitations, alternative fuels may carry risks, and low-carbon cement, steel and other materials remain costly and supply-constrained. Alternatives must be assessed in context rather than treated as direct, one-for-one substitutions.

Switching approaches could include circular use of excavation spoil, lower-carbon pile types and mixes, stone or soil-mix columns, and foundation reuse. Nature-based or “soft engineering” solutions may replace some hard structures, bringing potential carbon and biodiversity benefits.

The industry’s contribution can extend beyond decarbonising foundations and earthworks. Geotechnical expertise can support soil-carbon protection, resource circularity, deep geothermal energy and nature-based resilience. Soils are important carbon stores and play a vital role in climate mitigation and biodiversity recovery; restoration and measures such as biochar or enhanced mineral weathering may offer additional carbon-removal opportunities.

The presentation calls for collaboration among designers, contractors, suppliers, clients and industry bodies. It urges leaders to influence decisions early, invest in material and design efficiency, manage risk together and prioritise quality to avoid carbon-intensive remedial work. The broader goal is to move from extracting and disturbing the ground toward engineering it in ways that regenerate and protect this precious resource.
