Project duration

Usable space

3,500 m2 with refurbishment of existing buildings

Gross floor area:


The pharmaceutical group Bayer is expanding its production site in Weimar. Around 570 employees currently work at the site, which is the largest production facility in the city. The company plans to invest a total of around 35 million euros in the modernization.  

The existing space in the packaging building will be expanded by around 30 percent, with new space for additional lines and an expansion of the existing packaging lines. The challenge is to implement the project while operations continue and while maintaining the clean room conditions. 

Drees & Sommer has been commissioned with the EPCM model and supports the client in planning, awarding contracts, tendering and construction management through to turnkey handover.
