Data center construction capabilities

One Finnish partner for fast-track EPC delivery — from site preparation to cooling and fire protection.

One partner for the data center scope

Our companies operate under their own brands and management. For an EPC contractor, that means specialised, reliable partners across the whole construction value chain — coordinated through one group contact.

Data center schedules don’t wait. Neither do we.

Speed to power drives every data center project. Our model is built to keep the critical path moving.
