At the request of the contractor, CHINA BRIDGE AND ROAD CORPORATION, Zagreb branch, March 11, 2022. we performed a hydrographic survey of the derived state of the underwater part of the PELJESKO BRIDGE construction site. The survey was carried out for the purpose of entering the new construction and the waterway into the official nautical charts and other editions of the Croatian Hydrographic Institute. https://www.hhi.hr/vijesti/radni-posjet-drzavnog-tajnika-ministarstva-mora-prometa-i-infrastrukture-josipa-bilavera-hrvatskom-hidrografskom-institutu.

Lately, as the opening ceremony approaches, many pictures of the impressive Pelješac bridge have been appearing, from all perspectives showing the construction above the sea.

But what about the underwater part of the structure?
Here is a slightly different view of this exceptional bridge.

Below you can find a video and images showing raw multibeam point cloud dataset of the pile cap set on the subsea piles as well as the surrounding seabad.
These high quality data were collected as part of the hydrographic survey, that was carried out for the purpose of mapping the Pelješac bridge and newly established waterway in the official navigation charts and other navigation publications.

Video captured during the survey you can see on https://youtu.be/23xgQrkFV70 while 3D visualisation of the seabed and structure you can see on https://www.geomar.hr/assets/PB-Raw-MBES-dataset.mp4

View of the underwater part of the building: piles and the underwater part of the abutment on which the pillars of the Pelješko Bridge rest. The underwater part of the building was recorded in detail with a Teledyne RESON SeaBat T20-P high-resolution multibeam depth sounder.
