Scaffold Innovation at Hinkley Point C

 
Jun 1, 2022

Designing, building, and installing a suspended scaffold for a client, when some said it couldn’t be done: it’s all part of the job when you’re part of the team at KAEFER UK & Ireland

 
 

The scaffold, needed to enable the welding the equipment hatch onto the nuclear island inner containment liner at Hinkley Point C, used a bespoke design minimising the need to work at height. “We designed the scaffold so it could be built on ground level and then be lifted into position, focusing on buildability,” explained Thomas Hurst, KAEFER's Temporary Works Coordinator and Designer for the Hinkley Point C site.

Our innovative design allowed for critical path works on site to be replanned, allowing for early installation of the liner, a significant milestone for the client. The site team then ensured the scaffold was erected safely and professionally in a challenging reactive environment.

KAEFER‘s ability to be flexible to support the client allowed completion of the scaffold over a Bank Holiday, ensuring the clients programme could be met. The hatch was originally intended to be installed prior to the 47m wide ring being lifted into position but doing so would have delayed a critical element of the build project. “We proposed the suspended scaffold design to allow the project to continue on schedule, other contractors had said it couldn’t be done but we were confident we could design and build a safe, access system to meet the clients’ requirements,” said Thomas.

The final installation of the scaffold utilised the worlds largest crane, Big Carl, to lift the suspended scaffold which was erected at ground level approximately 270 metres away, and to place it into position 35m high in the liner.

As well as providing access solutions at Hinkley Point C, industrial services specialist KAEFER is responsible for delivering the containment liner coatings: surface protection for concrete in the internal building rooms of both nuclear reactors, and supplying high grade steel ducting for the nuclear island HVAC systems.
