The landmark Polyfytos bridge second inspection

The 45-year old 1372m-long bridge, which is the second longest bridge of Greece, was inspected recently to provide further insights to what was visually found to be vertical displacements of the deck of the balanced-cantilever part of the structure. This second inspection followed the topographic survey of the asset that was actioned with a UAV (drone) and geodetic total station and levels of the bridge deck were identified, preliminarily assessed and recorded, whilst a 3D digital twin of the bridge with its defects is underway.

The inspection was an organised endeavor to better understand the condition of the structure and discuss with Dr Telemachos Panagiotakos/DENCO Structural Engineering these first findings. This second endeavour is a preliminary and preparatory action.

Part of this inspection was a preparatory assessment of the pathways for communicating the potential risks to the local societies and businesses and the assessment of the potential impacts. This included the communication of the engineering findings to the local authorities and stakeholders.

The resilience of the bridge, the road network and the interoperabilities with energy assets are currently under discussion.

The infrastructuresilience.com group was there and results of the ongoing H2020 projects #Briface and #TRANSRISK and other research projects #ResilienTTS were communicated to the operators and the national TV #ERT1
