Our projects
Cardiff Canal Quarter
Cardiff Canal Quarter reconnects city, water, and community through a regeneration project that brings environmental performance and public value together. Featuring sustainable drainage solutions, climate-resilient planting and floating wetlands to reduce both flooding and energy demands for water treatment; we took key decisions governed by a commitment to reducing carbon and waste.
The scheme aligns with the Well-being of Future Generations Act 2015 in Wales, demonstrating how environmental design can support long-term social and ecological benefits as part of wider city regeneration.

Havant Thicket Reservoir
Havant Thicket Reservoir is a major water resilience project designed to help secure future water supply while creating wider environmental and community value. Developing the UK’s first major surface water reservoir in 30 years required navigating complex technical, environmental and regulatory challenges. We prepared high-quality planning applications and led comprehensive stakeholder engagement, securing planning permissions first time without post-submission design changes.
By establishing an agreed planning strategy at the outset, we reduced risk early, identified potential design issues before they became bigger problems, and supported proactive engagement with stakeholders and the local community. As a result, we were delighted to be awarded the CIEEM Best Practice Award for Stakeholder Engagement, reflecting the project's exceptional inclusivity and collaboration with local communities and environmental groups.
The team also addressed complex environmental issues, including mitigation for the loss of ancient woodland, geotechnical and geoenvironmental risks, and compliance with the Water Framework Directive, with no objections from statutory environmental bodies. The result reflects the strength of multidisciplinary collaboration and a balanced approach to water infrastructure, biodiversity, and community benefit.
M25 J10 and A3 Wisley interchange
AtkinsRéalis is National Highways’ key partner in developing the M25 J10 scheme in Surrey, providing the full suite of Development Consent Order related services from the earliest stages. Our role included advising on policy risks to inform optioneering, undertaking full preliminary design with associated environmental measures, and scoping the full range of environmental surveys, many of which were delivered in-house.
Stakeholder engagement was key – and the consented scheme was subject to a full Habitats Regulation Assessment, resulting in extensive habitat provision and the inclusion of a 30 meter wide heathland green bridge, the first of its kind in the country, reconnecting two Special Protection Areas previously severed by the A3.
Sizewell C
Building a nuclear power station on the Suffolk coast means working alongside some of the most sensitive habitats in the UK. Sizewell C sits next to a Site of Special Scientific Interest, and our environment teams are at the centre of making sure the project gets built without compromising what’s already there.
That means designing environmental mitigation schemes that go beyond ticking a compliance box. It means figuring out how to construct a six-lane crossing over a SSSI while maintaining the ecological integrity of the site. It means delivering temporary sea defences and environmental barriers that protect both the construction zone and the surrounding coastline. And it means building the environmental case that underpinned the Development Consent Order; one of the most complex consenting processes in UK infrastructure.
This is what environmental work looks like on a nationally significant project. Not an afterthought bolted onto the engineering; but embedded from the earliest planning stages, shaping how the project is designed, assessed and delivered. Our teams working on Sizewell C span environmental impact assessment, ecology, coastal management, hydrogeology, consenting and planning- collaborating with engineers, project managers and regulators to solve problems that don’t have a textbook answer.

Spains Hall Estate Beaver Reintroduction project
This pioneering nature-based solution helps mitigate flooding in Finchingfield, a historic village in northwest Essex. Working with Spains Hall Estate, the Environment Agency, and King’s College London, AtkinsRéalis supported a project that reintroduced beavers to a woodland stream for the first time in over 400 years in East Anglia.
The beavers have since transformed water movement across the estate, with dams creating ponds that store significant volumes of water and slow downstream flow during heavy rainfall.
Our role included advanced hydrological and ecological modeling to understand the wider effects of beaver activity and to help shape a Whole Farm Reservoir approach that identified where water could be stored naturally across the estate. We also created an animation to support stakeholder engagement and illustrate how the landscape and hydrology changed over time. Combined with drone survey data gathered by King’s College London, the project is building valuable evidence for long-term flood resilience, biodiversity gain, and the wider application of nature-based solutions.

Teesworks
Teesworks is one of the UK’s most significant brownfield regeneration projects, transforming a 2,600‑acre former iron and steelworks into a next‑generation green energy and industrial park. The scope of work is fast-paced and technically challenging, spanning large‑scale remediation, materials and waste management, highways and infrastructure delivery, demolition, earthworks and construction, all within a complex regulatory and stakeholder environment.
Working at Teesworks means operating at genuine mega‑project scale, where millions of cubic metres of material are being excavated, treated and reused under environmental waste permits, and where decisions directly influence programme outcomes, environmental performance and national policy confidence in brownfield regeneration.
This is a rare opportunity to work on a high‑profile UK project that combines technical depth with real‑world impact. At AtkinsRéalis, team members play a central role in developing innovative, first‑of‑kind approaches to materials reuse, waste regulation and sustainable delivery, while collaborating closely with contractors, regulators, clients and major industrial tenants. The pace, complexity and visibility of the work provide accelerated professional development, exposure to strategic decision‑making and the chance to help shape best practice across the wider business.
