AVI GmbH is founded by Sigfried and Mirko Wittek as well as Gerd Müller with headquarters in Hoyerswerda. The young office quickly establishes itself as a competent and reliable partner for sophisticated engineering services.


With the strategic partnership with Proplan GmbH, new exciting projects are being created.


A new generation is taking over. The 27 year old Dipl.-Ing. Frank Seifert and the 30 year old Dipl.-Ing. Veit Menges are from now on partners in the company. The growth remains unbroken. Important projects in Germany and beyond continue the success story.


Siegfried Wittek relocates the AVI GmbH headquarters to “An der Schule 10” in Hoyerswerda. The first foreign project brings our experienced engineers to the Czech Republic. Dipl.-Ing. Carsten Besen is appointed partner.


AVI GmbH completes the generational change. Dipl.-Inf. Mirko Wittek becomes managing director next to Frank Seifert and from now on directs the fate of the company. After a four-year construction period, the Profertil project in Argentina is completed.


The company is growing steadily. With comprehensive know-how, projects of any type and size can be planned with confidence and accompanied until the start of use. The first complete system was planned, manufactured and commissioned in Madrid at BP Solar.


The second branch of AVI GmbH is ceremonially opened in Leuna. Hans-Peter Graul takes over the management of this location.


The team of AVI GmbH is awarded with the Oberlausitzer Unternehmerpreis. Since 1996 the prize has been awarded annually and honours the achievements of the young company.


Two projects in Australia are being realized through strategic partnerships. Thus the AVI GmbH team has realized projects on all continents. Competent – flexible and services “Made in Germany” prove the good reputation.


Renewed nomination and achievement of the second stage “Grand Prix of Medium-Sized Enterprises”; turnover exceeds € 3 million for the first time


Due to the constant growth of the team, new and larger premises are required. AVI GmbH moves into the building of the former Sparkasse in Hoyerswerda and can develop freely here. Due to the new spatial possibilities, switch cabinets can now be built directly on site in cooperation with the company Prowatec GmbH.


On 21.01.2017 AVI GmbH celebrates its 25th anniversary. 25 years of AVI GmbH are not only 25 years of economic development of a “start-up company” from Lusatia, they are above all 25 years full of challenges, technical progress and constantly changing conditions.


Generation change at the Leuna location – After 13 years as branch manager, Hans-Peter Graul hands over the management to Matthias Piehler. Mr Graul will continue to work for AVI as a more experienced employee.


We started the year with a major order at the ArcelorMittal steelworks in Eisenhüttenstadt. We have completed exciting projects. We were able to recruit new employees. For the first time we were able to achieve a turnover of € 4 million.


AVI becomes part of the Global Division Automation & Engineering of the Leadec Group.
