This talk will demonstrate how innovative surveying and sensing techniques can improve our understanding of the current damage state of building, and allow tracking its response during tunnelling with unprecedented detail.

Construction of tunnels in urban areas requires careful consideration of the impact of ground movements on existing structures. This is particularly challenging when the structures affected by the works have heritage value.

This was the case during the recent Bank Station Capacity Upgrade works, where two Grade-I listed buildings (St Mary Abchurch and Mansion House) were located in close proximity to new tunnels. During design, engineering judgement was necessary to overcome critical uncertainties associated to the structural materials and the foundations, and the hidden defects present in the building.

This talk will demonstrate how the innovative surveying and sensing techniques adopted on this project can improve our understanding of the current damage state of building, and allow tracking its response during tunnelling with unprecedented detail. The role of this data in improving engineering judgement is then illustrated with the development of new modelling approaches.

Speaker

Sinan Acikgoz is an Associate Professor at the Department of Engineering Science of the University of Oxford. His research group investigates the use of non-contact surveying and monitoring techniques to better understand historic structural materials and their response to loads.
