Oxsfordshire Grade II* listed building
The project focused on the assessment and structural evaluation of two historic stone pillars at a Grade II* listed property in the UK. Our work included structural survey, non-destructive tests and structural health monitoring, and the definition of intervention requirements and methodology, aiming to safeguard the pillars while minimising intervention and preserving their heritage value.
Concept & Challenge
The primary challenge was to assess and stabilise the stone pillars while ensuring the safety and integrity of the structures and their surroundings. The project required a detailed understanding of the construction, material and safety conditions and structural behaviour of the pillars, for the development of a minimal-impact intervention.
Approach & Methodology
The work began with a comprehensive on-site inspection, supported by LiDAR scanning and experimental sonic testing to characterise the stone masonry, evaluate the condition of the pillars, and identify the underlying causes of deterioration. Based on this assessment, intervention requirements were defined to ensure long-term stability while avoiding unnecessary works, including the installation of a Structural Health Monitoring System (SHMS) to track pillar behaviour and inform any future interventions.
Solution & Results
The assessment and subsequent monitoring programme provided detailed insight into the structural performance of the pillars and informed appropriate conservation interventions. The work combined minimal, targeted strengthening with continuous monitoring, ensuring the long-term stability and preservation of these heritage structures.
Assessment of historic stone pillars at a Grade II* listed property, integrating detailed inspection, advanced surveying techniques, and practical conservation strategies. The findings provided the foundation for a carefully designed minimal-intervention approach.
