In 1992 the present

ERCOSPLAN Group of Companies

was created out of the former Kali-Ingenieurbuero Erfurt, the central planning office of the East German potash industry, which has been active under different names in Erfurt, Thuringia since 1955.


From 1950 to 1990,

over a period of 40 years, East Germany became the third largest potash producer world wide, with the Kali-Ingenieurbuero being their sole planning office handling projects with a total value of about € 5.5 billion.

In 1990

after the reunification of East and West
Germany the company was privatised under the name KIB Plan GmbH, taking over the most experienced staff and the complete know how of the former Kali-Ingenieurbüro.

In 1992,

right after a management buy out, the name was changed to ERCOSPLAN Erfurter Consulting und Planungsbuero GmbH.

Later in the 1990`s,

due to the excellent development of the company, several subsidiaries were formed and strategic acquisitions have been made.

Today ERCOSPLAN, still managed by the owners, employs 125 engineers, scientists, technicians, economists and computer experts, performing an annual turnover of about 10,000,000.00 €. Services include, among others, surveying, consulting and planning, project management and supervision of installation and start up, as well as  project management.
