About the company

The TDA Technical Services and Plant Construction GmbH was founded in 1993 as the largest MBO in East Germany from the former technique and maintenance department of „Chemiekombinat Bitterfeld“ with 560 employees at that time. In 2001, the company became a subsidiary of Leuna-based MCE VOEST VEA GmbH In October 2009, the MCE Group was bought by Bilfinger and Berger, including the Bitterfeld site.

Restructuring in the group has resulted in the closing of  Bilfinger Maintenance GmbH branch in Bitterfeld in May 2016 and adding the individual departments to other branches in the vicinity. Following discussions with the management in October 2016 and almost a year of negotiation, the plastics processing and machining divisions of the Bitterfeld site were bought by Frank Zöllner.


It results in a "new" TDA Technische Dienste und Anlagenbau GmbH and starts Oct. 1st 2017 with actual 21 employees.
The main field of activity is the provision of industrial services (maintenance), plant and pipeline construction, machining as well as the trade in plastic pipes and semi finished products and plastics processing.
