Profile

1991

Our office was founded as the Vermessungsbüro Flach & Ziesemann GbR with the same graduate engineers, Mr. Gerd Flach and Mr. Ulf Ziesemann. Originally 3 small offices (Gotha, Jena, Ilmenau) developed into an efficient medium-sized surveying office in Weimar. 1995 Based on economic and legal considerations, we founded the Vermessungsbüro Flach & Ziesemann GmbH. With his appointment as a publicly appointed surveyor of the Free State of Thuringia, Mr. Ziesemann was forced to spin off his office from the company.
