Engineering support across the project lifecycle
Our involvement can start with a specific technical requirement or extend across the engineering lifecycle, with experienced project management providing a clear point of responsibility throughout.
Our teams can support requirements capture, feasibility and optioneering, concept and detailed design, substantiation, procurement and manufacture support, testing, installation, and commissioning, through to plant life extension, obsolescence management, and upgrades.
By combining engineering expertise with structured management of scope, programme, interfaces, quality, and deliverables, we help maintain continuity as projects progress, reduce delivery risk, and ensure engineering decisions consider how the solution will be manufactured, installed, operated, and maintained.
Whether you need specialist support for a defined requirement, additional engineering resource, or a multidisciplinary team to deliver a work package, we can scale our support around your project.
40 years of engineering excellence
Actemium Design UK’s engineering heritage dates to 1987, when North West Projects was established as a specialist CE&I engineering business supporting the nuclear sector.
Over the following decades, the business developed into a multidisciplinary engineering organisation, building experience across nuclear decommissioning and other complex, safety-critical programmes.
North West Projects joined VINCI Energies in 2017 and became Actemium Design UK in 2021. Today, we combine that established engineering experience with the wider capabilities and resources of Actemium UK and the VINCI Energies network.
Trusted across the nuclear sector
Our nuclear customers
Recognised for engineering delivery and collaboration
Beyond nuclear engineering
While nuclear engineering is a core area of expertise, Actemium Design UK also supports customers across defence and other complex, high-integrity environments.
Our experience of safety-critical engineering, demanding regulatory requirements and technically challenging operating environments enables us to apply proven engineering approaches across a broader range of projects and programmes.
This includes specialist mechanical, process, CE&I, stress analysis, and multidisciplinary engineering support, with solutions developed around the specific safety, operational and technical requirements of each application.
