The Group’s key technical planning expertise is bundled in our Central Technical Division (Zentrale Technik – ZT). We provide our comprehensive services for Group-wide support in our overarching specialist disciplines of turnkey construction, structural engineering, civil engineering, tunnelling and transportation infrastructures. ZT accompanies the entire construction process, from acquisition to tender processing to execution and commissioning.
 
ZT also offers innovative solutions for buildings and infrastructure, including building construction, building envelopes, technical equipment and LEAN.Construction. Our innovation activities focus on holistic, target-oriented system design in conjunction with smart buildings and design-to-production solutions.
 
We see sustainable construction not only as an upcoming challenge, but above all as an opportunity. The construction sector increasingly sees itself as having a responsibility to develop resource-saving technologies. We at ZT are also aware of this responsibility. To this end, we are working on solutions in all specialist areas to promote resource-efficient construction for all our business areas. A key success factor here is integrated planning based on the lifecycle approach, which takes into account the principles of the circular economy.
