Large Plants

We feel at home in large plants!

Completing complex projects under difficult external conditions is increasingly a special challenge in the international competitive environment. Tighter specifications (quality/cost/
time) demand more detailed engineering and the ability to master the risks through qualified project and site management.

We can assist you with your projects, from specialists through to managers, in all requirements and project phases worldwide in your home office or at the site.By integrating our staff or specialists in the design phase as well, you can save time and money. Traditional component suppliers also need to expand their range of services to include “lump sum turnkey” (LSTK) suppliers. We are prepared to do this and also provide country-specific solutions.

We fully understand your needs and are able to support you worldwide regarding the site management of your complex large plant projects.
