Central Plaza supernodes remote camera inspection - Murphy Geospatial

Project summary:

Live stream remote camera inspection of nodes at Central Plaza in Dublin city centre.

The brief:

We were asked to carry out a remote camera inspection of the steel node boxes at Central Plaza, the eye-catching office building on Dame Street in Temple Bar. The building, famous for its ‘suspended’ design, was built in the 1970s and is undergoing renovations as part of ambitious plans to create a new city centre destination.

We were required to provide a detailed conditional survey of the steel Macalloy bars built in eight confined chambers of each node. The live stream remote camera system we used provided a real-time view of the inspection, allowing both HD video and still image capture to help with both in-situ and subsequent analysis.

Our role was to provide a high-resolution inspection of inaccessible areas of the superstructures to enable the project’s structural expert to address the detected defects and to verify the final quality of renovation works.

The challenges:

We had to work in a very confined space with the videoscope camera to provide a full inspection of surface imperfections.

Each chamber contained two bars and the position of the nodes and the bottom chambers made it difficult to access. It was a challenge to navigate the camera steadily.

We faced further challenges because of Covid-19 but, working with our partner companies, we secured safe and on-time inspections to provide the live stream camera service. Our non-destructive testing (NDT) team liaised with structural experts via Microsoft Teams, enabling a high-resolution in real-time inspection and a visual quality assessment.

Our work:

Our fully-trained and experienced NDT operators employed an advanced videoscope 8.4mm high-resolution waterproof camera on a bendable insertion tube to access all the confined spaces and to enable a comprehensive and interactive visual inspection.


Murphy Geospatial virtual inspection allowed engineer based off site to review and inspect without having to travel to site. Besides the live streaming inspection in real-time, the whole process was fully recorded in the form of HD videos and still images. All the findings and observations were documented in the technical reports.

Murphy Geospatial’s NDT team can be relied on to work in successful partnerships to deliver inspections such as this – enabling clients to make strategic decisions with confidence, reducing risk across the project or asset lifecycle. Our accurate data has helped many clients in their key decision-making.
