Construction Assessor Dr.-Ing. Hans-W. Dahlem is celebrating his 80th birthday in March 2019. He looks with pride on his life's work at the engineering company DAHLEM. Hans-W. Dahlem studied civil engineering at TH Karlsruhe. A subsequent internship as a Construction Assessor in the Water Management Department of the State of North Rhine-Westphalia followed his doctorate at the TU Darmstadt in 1977. In 1978, Hans-W. Dahlem joined the engineering office of his father Hans Dahlem, the company founder. Under his leadership, the company expanded with further offices - also abroad. The number of employees is growing and the areas of activity are constantly expanding. Already his father made his first contacts abroad early on, which he continued to expand. He has extensive international experience, especially in Eastern Europe, the Middle East, Africa and Asia. The life's work of Dr. Hans-W. Dahlem can also be expressed in figures: During his management, the company grew from 25 employees at a regional engineering office to an international company. Currently, more than 125 people work for DAHLEM worldwide, 80 of them at the headquarters in Essen. During his long tenure as a Managing Partner, Dr. Hans-W. Dahlem has been a member of various chambers and associations, including a board member at the Institute for Water Supply, Wastewater Disposal and Spatial Planning WAR of TU Darmstadt. In 2012, Hans-W. Dahlem gradually withdrew from business and more and more placed the company’s management in the hands of his son, Dr.-Ing. Jan-Gregor Dahlem.
