Keynote Lecture: Foundation Re-use, Principles for a new business model for the Piling Industry-PPT Presentation

PPT Presentation

Pdf Summary

The presentation argues that foundation reuse is longstanding but has become uncommon in modern construction. Historically, buildings were often rebuilt on existing foundations; today, engineers may work around old foundations or remove them because they limit design freedom and introduce perceived risk. Contractors have often accepted this approach, making new piling or removal part of established business practice.<br /><br />Reuse is increasingly important because urban sites are congested and sustainability goals demand lower carbon emissions and more efficient use of resources. Existing foundations can avoid the material, emissions and disruption associated with installing new ones. Yet reuse involves uncertainty about the condition and loading of the existing structure, complex project planning, and unclear responsibility and risk allocation. Unlike new construction or foundation repair, the industry lacks a clear business model for reuse.<br /><br />A key enabler is traceability: material certificates, as-built drawings and construction records allow future engineers and contractors to assess foundations and plan inspections. These records should be treated as valuable assets, not administrative burdens.<br /><br />The presentation concludes that foundation reuse does not necessarily require an entirely new business model. Instead, the industry must change its culture, contracts, procurement practices and sharing of responsibility. More open dialogue and appropriate risk allocation can make reuse workable. The foundations built today should also be designed and documented for future reusability, helping reduce carbon footprints over time.
