From the primary core business, engineering of control centres for utilities, we extended our engineering services. Today we provide planning and consulting for the following scope:

Ingenieurbüro Klein was established in 1981 by Dipl.-Ing. Ewald Maximilian Klein in Dietzenbach, Germany, providing support and planning for control centres for utilities during engineering.

In 2002, Dipl.-Ing. Gerhard Jost, the son of the company founder, assumed management of the firm, making Ingenieurbüro Klein a family held and managed company in the second generation.

1991 the company expanded its capacity and scope through the founding of Elektrotechnik GmbH, headquartered in Haßloch, Pfalz, Germany. Former Managing Partner Dieter Himmighöfer became sole shareholder in 2018 and introducing his son Dipl.- Ing. Marco Himmighöfer into the company is ensuring the continuity as well as the cooperative partnership between HIPLAN (http://www.hiplan.de/ ) and Ingenieurbüro Klein.
