Photogrammetry

Photogrammetry is the use of photography in surveying and mapping to ascertain measurements between objects and has been used system wide across the Euston South Enabling Works. It has been essential to provide better visuals and accurate data to locate and expose underground services from trial holes that are being carried out on various sites.

This method has ensured that we can plan effectively for future exposure of the ground and reduce the risk of a strike which could seriously injure our staff. The engineering team are crucial in this process because they collect and collate this data which then helps the survey team to provide up to date information for the foreseeable future.

This technique was used in Central London locations where trial hole works were required on footpaths. The survey team helped the engineering team gather the right information and demonstrated the importance of capturing good quality images for that they were able to produce a 3D model.

Photogrammetry ensures that planning implemented into excavation works can be more efficient, which saves time and money rectifying unnecessary works. It is a straightforward process that can be employed using a phone or a tablet, allowing the turnaround on modelling to be quick with outstanding results providing a good visual that all parties can use.
