AtkinsRéalis signs new civil works agreement at Sizewell C

MONTREAL, July 6, 2026 /CNW/ - AtkinsRéalis Group Inc. (TSX: ATRL), a world-class engineering services and nuclear company with offices around the world, has signed a new five-year framework agreement to continue its civil works role at Sizewell C, a new 3.2 - GW nuclear plant in the south of England. AtkinsRéalis will act as design partner for the permanent civil works, building on years of support to the Sizewell C project through joint commitments on schedules and delivery excellence.

"Common outcomes and shared responsibility across delivery partners maximize opportunities for innovation and collaboration", said Ian L. Edwards, President and CEO of AtkinsRéalis. "This appointment reinforces AtkinsRéalis' expertise in delivering new nuclear build programs and the confidence placed in our teams at Sizewell C to help de-risk delivery and achieve greater certainty for this nationally significant project."

AtkinsRéalis is providing multidisciplinary design and engineering services across the permanent plant design at Sizewell C, including the Conventional Island, Balance of Plant, Heat Sink Buildings and Ancillary Works.

This builds on the extensive role AtkinsRéalis has played to date across planning, consenting and enabling work phases at Sizewell C, and enables AtkinsRéalis to continue bringing both new and established digital tools into the delivery of the civil works program.

"AtkinsRéalis has played a significant role in design and engineering management at Sizewell C since 2019, bringing knowledge, experience and learnings from a decade of delivery at Hinkley Point C. Our design and engineering teams have pioneered new digital technology and data-led design to streamline schedules, increase certainty and mitigate program risks at Sizewell C. This new agreement renews our commitment to realizing the full benefits of replication and unlocking even greater efficiencies through excellence in delivery," said Joe St. Julian, President, Nuclear, AtkinsRéalis.

Under the new agreement, AtkinsRéalis has reinforced its commitment to building a lasting impact in the community at Sizewell C, including through its work with local supply chains as well as strategic programs with schools and further education facilities to build interest and awareness of careers in Science, Technology, Engineering and Math (STEM) that have already reached over 1,500 students at more than 50 schools and colleges in and around Suffolk.

In the UK, AtkinsRéalis supports EDF's (Électricité de France) operational fleet and new build program, including design & civil, mechanical, electrical, process and nuclear engineering support for the end-to-end development of Hinkley Point C. Prior to this agreement, AtkinsRéalis delivered a broad program of design, engineering and project management at Sizewell C, including the design and engineering of vital utilities and water networks, earthworks, buildings and structures to create the construction site; new infrastructure including upgrades to local rail and road links, new marine and landing facilities; along with new offsite accommodation campuses, freight management and park and ride facilities.
