Foundation Re-use: State Of The Art

Authors: Assistant Professor Samirsinh P Parmar

Abstract: The re-utilization of existing foundations for new structural applications has emerged as a sustainable and cost-effective engineering strategy, minimizing construction expenses, material consumption, and environmental impact. However, foundation re-use poses significant challenges, including geotechnical uncertainties, structural compatibility, load redistribution complexities, and compliance with evolving design standards. This paper presents a comprehensive state-of-the-art review on foundation re-use, systematically addressing its challenges, feasibility assessment techniques, and structural evaluation methodologies. A detailed step-by-step procedural framework is proposed, integrating geotechnical investigations, structural capacity verification, retrofitting techniques, and risk mitigation strategies to facilitate the successful adaptation of existing foundations for modern infrastructure. Furthermore, insights from recent case studies, advanced numerical modelling, and non-destructive testing (NDT) techniques are explored to enhance decision-making in foundation re-use. This study aims to provide a robust engineering methodology, bridging the gap between theoretical advancements and practical implementation in civil engineering. The findings contribute to the evolving discourse on sustainable foundation engineering, particularly in urban redevelopment and infrastructure resilience.
