Welcome to ISKA Schön GmbH!

ISKA Schön GmbH was founded in 1961 as a traditional building firm employed in the field of general civil engineering. After 29 years working for ISKA as a Site Engineer, Hartmut Schön acquired the company ISKA Wiedenmann GmbH in the year 2000 and changed its name to ISKA Schön. An average of around 160 - 180 employees work for ISKA Schön GmbH, 25 of which are salaried staff.

Since the change in the company's name, the building firm has metamorphosed into a construction services provider for public
utilities and energy suppliers.
