Founded in 1999 by Alexander Klein, the company quickly became a specialist in the construction of data centers. In addition to data centers, we also design office buildings, storage facilities, and all the supporting infrastructure needed for these projects. Since 2025, we are part of Arcadis, the world's leading company delivering sustainable design, engineering, and consultancy solutions for natural and built assets. We’re excited to develop this new chapter in our success story.
