Data centre planning, design & engineering consultancy

Sweco’s team of teams brings together specialist mission critical expertise, strong localised presence across Europe, and integrated technical leadership to support your data centre infrastructure projects from early strategy through to operation.

Data centre projects are complex, time‑critical and increasingly constrained by planning, power and sustainability requirements. Our dedicated DC consultancy supports clients in navigating this complexity – helping you make informed decisions, manage risk and deliver resilient, future‑proof facilities across Europe.

Our experts bring together global data centre planning, design & engineering experience and unique multi-national technical capability from site acquisition to project completion. Delivering 5.5GW across the UK and globally in 11 countries, our clients see us as their most committed and reliable partner for facilities worth over EURO50bn.

Full lifecycle expertise

Strategy & business case

Helping define the right solution from day one – aligning capacity, resilience, cost and programme with commercial and operational goals.

Site selection & due diligence

Assessing sites across planning, power, utilities, access and environmental impact – using local insight to identify and mitigate risk before commitment.

Concept & master planning

Developing scalable, flexible concepts and masterplans that support phased delivery, future expansion and long‑term operational efficiency.

Planning & consent

Navigating local planning frameworks and regulatory requirements, supported by teams on the ground with established stakeholder relationships.

Detailed design

Coordinating multi‑disciplinary engineering to deliver technically robust, buildable designs that protect programme and performance.

Procurement

Supporting procurement strategies that align with programme certainty and mitigate delivery risk.

Construction & delivery

Providing technical oversight, design support and joined-up project management throughout construction to maintain quality, manage change and keep delivery on track.

Testing, commissioning & handover

Ensuring systems perform as intended, risks are closed out, and facilities are handed over ready for operation.

Our approach

European reach with local understanding

We work across Europe, with teams already embedded in both established and emerging data centre markets. This breadth allows us to support programmes across multiple sites in multiple geographies, while our local presence helps manage the specific regional risks associated with planning, permitting and delivery in different regulatory environments.

By working with a full ‘ecosystem’ of experts who understand local conditions and stakeholder expectations, you will benefit from smoother engagement with authorities and greater confidence in site viability and programme.

Dedicated mission critical expertise

Our data centre work is delivered through dedicated mission critical teams. This means specialist knowledge is not diluted across sectors, and projects benefit from people who understand the specific demands of data centre delivery.

Sweco’s unique, integrated delivery model keeps teams aligned and ready to respond as requirements change. This avoids the delays, competing priorities and complexity that can arise when advisory, design and specialist teams are more fragmented and reactive.

Trusted design leadership

Successful data centres rely on strong coordination across multiple technical disciplines. We provide clear design leadership through dedicated design management, working alongside project management to ensure technical solutions are coordinated, risk controlled, buildable and aligned with programme objectives.

This structured approach helps identify and resolve issues early, supporting better decision‑making and reducing the risk of late‑stage change.

Supporting programme certainty

Programme certainty is central to data centre delivery. Our teams focus on identifying risk early, overseeing project dependency mapping, coordinating disciplines effectively and responding constructively to change.

By combining technical expertise with clear communication and structured design management, we help clients maintain momentum and make informed decisions that support delivery against critical milestones.

End-to-end collaboration

We support data centre projects across the full lifecycle. Clients can engage us at any or all stages – whether for targeted technical input or continuous support from early strategy through to handover.

Early involvement allows us to add the greatest value, helping to shape viable strategies, reduce risk and align technical decisions with programme, cost and operational objectives.
