On March 1st, 1998, we founded, that is; Ingo Gralka, Andrea Kühnhold and Alexander Zeh, the company GKZ Bau. Our medium-sized construction company based in Gotha employs around 20 people. We operate primarily in Central Thuringia, but also beyond state borders if necessary. We have constantly adapted our service profile to the requirements of the times. Our own staff is constantly provided with the necessary know-how. This doesn't just happen during training, but especially in day-to-day work. Since construction tasks are becoming increasingly complex and demanding, we have focused exclusively on building construction projects from the beginning.
