[INNOVATION] As Reactor Building 2 has just been crowned with its Dome, the implementation of a modular prefabrication approach marks another key milestone at the Hinkley Point C site.
And a close collaboration between BYLOR Joint Venture (led by Bouygues Travaux Publics and Laing O'Rourke) and EDF Energy made it a reality! 💪
Launched and developed since early 2024, this innovation represents a real shift in the way we build, delivering significant gains in safety, scheduling, quality, and on-site efficiency.
The concrete benefits?
✅ Fewer concrete pours on site
✅ Reduced congestion and co-activity
✅ Improved Prefabrication Yard quality (coatings, finishing works partial fit-out)
✅ Significant reduce of working at height, elimination of overhead works and improvement of safety at work
✅ Optimised planning and sequencing
✅ Scalable method for future projects
💡 A new step toward the industrialisation of nuclear construction!

The modular precast solutions were generated from last year's innovation focus where we were asked by our client. How can we do things differently? How can we accelerate the program? And how can we improve safety and quality? We started to isolate complex concrete structures and started to think out-of-the-box by actually creating boxes. Working on the elements in the precast yard means we have better control over working at height and our safe systems of work. The HL23 Peos, as we call them, are the first of a kind to be produced. This innovation required a great collaboration between NB, JDO, bylaw teams, temporary work, precast and delivery. The number of pores and the complexity of some of the walls is one of the most challenging scopes that we've produced to date. We are now opening a door to further innovation as we are building differently with modularization. Today we are just installing concrete boxes, but we could install later concrete boxes with mechanical or electrical supports. And why not even equipment? So two of the smaller modules weigh around 360 tons and the two heavier modules weigh 495 tons. The total concrete for all four elements will be around 580 meters cube and the total rebar volume around 230 tons of rebar. Across the four modules, there will be a total of 15 number of concrete pours completed. There will be installed by our close neighbor Big Carl, lifting them from the precast yard on K10 over the top of the Dome and into the Unit 1HL23 building. I'm amazing milestone today, not just for the safeguard bullies, but for the project on the whole. I think today demonstrated our capabilities in producing these first of a kind innovations doing me proud with the team for for all of the teams actually involved in it. And it took many different things from the from the designers to the delivery team to the precast teams to the lifting guys. So the guys on the ground have actually made it happen. Takes a lot to bring it all together. It's a sort of sort of engineering that most engineers live for.
