Data Center Infrastructure — From Foundations to Substations
Anfra executes data center civil engineering, foundations, concrete structures, and substations for projects throughout Finland and Northern Sweden. Our in-house engineering department provides specialized geotechnical and structural design. Our Design & Build model minimizes interface risks, enhances efficiency, and accelerates the project schedule.
We have extensive experience in numerous data center projects and their specific requirements. We can mobilize on-site within just two weeks of an agreement, supporting the fast-track nature and tight schedules of data center developments.

Finnish Data Center Association
Bespoke data center design and construction
Data center construction requires specialized expertise, as these facilities are critical infrastructure where operational reliability, security, and structural durability are paramount.
Designing these facilities requires a tailored, site-specific approach. Geotechnical conditions, structural loads, security requirements, and future scalability must be integrated into the project right from the initial stages. Anfra provides data center developers with a comprehensive, end-to-end service that includes:
- Geotechnical and structural design specifically for data center environments
- Comprehensive earthworks and site preparation
- Foundations, concrete structures, and other critical infrastructure
- Substations and grid connections
- Security and physical protection (including fencing, access control areas, and firewalls)
- Integration of execution with overall technical and MEP (Mechanical, Electrical, Plumbing) design
For the client, the most time- and cost-effective delivery model is often the Design & Build (D&B) contract. This model seamlessly integrates Anfra's In-House design expertise with our practical production experience, minimizing interface risks, accelerating delivery, and ensuring superior total cost control.
Strong expertise in data center design
Our own In-House Engineering Department is responsible for the geo- and structural design of data centers. The structural design of data centers is always done on a site-by-site basis to ensure that the end result is both secure and cost-effective. High-quality design ensures smooth implementation and a long service life.
In the structural design of data centers, we take into account, among other things:
High point and payloads
Vibration and compression risks
Fire resistance and safety of structures
Possible future extensions
High-quality and careful planning lays the foundation for smooth construction, cost-efficiency and trouble-free operation of the data centre throughout its lifecycle.

This experience also gives us excellent capabilities to design and build data centers reliably, efficiently and in line with the client's objectives.
Frequently Asked Questions (FAQ)
Does Anfra have experience in data center projects?
Yes. We have successfully completed four data center projects in Southern Finland. Due to the confidentiality of these projects, we cannot disclose client names, specific locations, or detailed contract information—NDA practices are standard in the data center industry.
Our broader reference portfolio includes several substation projects in the 110–400 kV voltage range, providing a solid foundation for constructing power connections and infrastructure for data centers.
What does an Anfra's data center contract typically include?
Anfra delivers the physical infrastructure for data centers, including civil works (clearing, leveling, drainage, excavation/blasting, and load-bearing layers), foundations and concrete structures (slab foundations, column footings, and piling), substations (interconnection and transformer stations), as well as fencing, roads, and finishing works.
Furthermore, our in-house engineering department is responsible for geotechnical and structural design, enabling our Design & Build (D&B) delivery model. In this model, design and construction progress in parallel, which shortens the overall project timeline and minimizes interface risks.
Can Anfra deliver both the substation and civil works in a single contract?
Yes, and this is one of our core strengths. When the same contractor is responsible for both the substation (e.g., 110 kV grid connection, transformer stations) and the entire site’s civil works, foundations, and concrete structures, interface management is simplified and the overall project schedule is accelerated.
Why choose Anfra as an infrastructure contractor for a data center project?
First, we master civil engineering, concrete construction, and substation infrastructure—providing the client with a single contractor for the entire physical execution, effectively eliminating interface risks. Second, our in-house engineering department enables a rapid project start and the Design & Build (D&B) delivery model, which typically shortens the overall project timeline. Third is our mobilization capability: we can commence on-site operations within just two weeks of a contract agreement.
What is Anfra’s response time for data center projects?
We understand the critical importance of the 'Time-to-Market' factor in data center investments. Our competitive advantage lies in rapid mobilization and the ability to commence work immediately upon the completion of pre-engineering. With our in-house fleet and experienced team, we are ready to tackle even the most demanding projects.
Do you manage the strict tolerances and quality requirements of data centers?
Yes. Data center construction is a game of millimeters. We utilize the most precise measurement methods and document quality assurance at every stage (in accordance with the ISO 9001 standard). Our foundation work ensures that sensitive equipment and technical connections remain perfectly level and aligned.
How do you handle confidentiality and security?
We have established processes for handling confidential projects. Our personnel hold the necessary security clearances, and our project management complies with the most stringent data security standards. We do not disclose client details or site locations without explicit authorization
On-site, we strictly adhere to the security and confidentiality protocols established by the client, and our entire workforce is fully committed to them. Operating under an NDA does not impact the quality or efficiency of our work; it is a standard part of our operational model.
In which regions does Anfra execute data center projects?
Throughout Finland and Sweden. While our data center projects to date have been centered in Southern Finland, our organization is fully equipped for nationwide operations—our substation expertise spans from the northernmost reaches of Finland to the south. We have also executed similar industrial and substation construction projects in Northern Sweden. As the data center investment boom continues to expand into new regions, we are prepared to scale our operations accordingly.
