In it for the long haul
Records show that collaboration and innovation are key to keeping projects on track
THE NUCLEAR INDUSTRY IS UNDER pressure to reduce the cost of new build projects, whose sheer size, complexity and hence long payback have become a deterrent to potential financiers. Jacobs’ record in new build shows that by working
collaboratively with reactor vendors and developers, it is possible to introduce innovations that will manage and mitigate the risk of schedule overruns. Jacobs’ support for Hinkley Point C, the U.K.’s first

nuclear new build project for 25 years, began back in 2010 when the project embarked on the General Design Assessment regulatory approval process. With construction now well under way, Jacobs is now Delivery Partner for program, project and construction management services on the earthworks, main civil works, marine works and heat sink systems. EDF is building two 1.6 GW EPR reactors at Hinkley. In between the construction of the nuclear island concrete basemats for Units 1 and 2, Jacobs worked with supply chain companies to introduce many process improvements and innovations. As a result, about 500 tons of the 4,500 tons of reinforcing steel in the Unit 2 common raft was prefabricated and installed in modules, saving significant time and labour costs as well as improving safety by eliminating multiple risks. Jacobs Construction Manager Mike Murphy says: “The
learning that we were able to apply from Unit 1 helped to ensure that Nuclear Island Unit 2 was delivered on the day that was forecast four years ago. This demonstrates a level of schedule predictability only achievable by close, collaborative and focused teamwork by the entire supply chain from design through to concrete placement.” To date, our involvement in site design works at Hinkley
has also included station seawall and associated defenses, construction material jetty and plant delivery wharf, seawater intake and outfall heads, and the U.K. context for non-U.K. plant design. Jacobs is the sole supplier of independent assessment
and assurance for all aspects of non-destructive testing inspection qualification for Hinkley Point C. The role of our Inspection Validation Centre (IVC) in Warrington, U.K., is to independently check inspection methods – and assess and qualify the inspectors who will apply them – to ensure that they can detect any defects that could compromise the structural integrity of critical reactor components during the plant’s lifetime.
