About us

HI-TEC ENGINEERING for over 35 years

CRC is an internationally active planning office for the high-tech and life science industry and research. We specialise in laboratories, clean rooms, research buildings and highly installed production buildings. We plan all technical trades to supply production technology, processes and the production environment.
Our services have a wide range: feasibility studies, inventories, layout planning, laboratory planning, planning of equipment connections (hook-up), object planning, technical building equipment, construction supervision, up to the complete realisation of new buildings, conversions or extensions as general planners.
Our engineers and architects, natural scientists (biologists, chemists, physicists), technicians and system planners are able to provide the entire planning spectrum in a comprehensive and highly specialised manner.
We are engineers with heart and soul who enjoy solving highly complex tasks and always find the best possible solution for our customers.

CRC Clean Room Consulting GmbH – Gesellschaft für Reinraumtechnik – was founded in 1983 in Freiburg as an engineering office for construction projects in microelectronics.
The company quickly developed into a specialist for clean room technology.


As a cleanroom pioneer, CRC introduced the filter fan units (FFUs) in 1987, which are now the common standard in cleanroom technology.
1987 Planning of the first cleanroom based on the filter-fan concept for the TU Berlin, research focus on microperipherics, cleanroom area 1,350 m², completion of new cleanroom in 1989, planning CRC Freiburg, execution LTG Stuttgart.


the range of services was expanded by taking on experienced industrial architects. In combination with the competences in technical building equipment, all essential planning services can now be provided from a single source.


the Life Sciences division was founded. The knowledge of clean room technology and ultra-clean media supply were good prerequisites for the successful development of our planning activities.


the branch in Belgium was transferred to CRC Engineering BVBA. This created the structure to continue growth with our customers.


Additional office space was acquired at the CRC location in Freiburg, strengthening the planning team both qualitatively and quantitatively.


Planning of very large semiconductor factories at home and abroad.

since 2018

Planning of gigafactories for internationally leading battery cell manufacturers.


At the CRC location in Freiburg, the ongoing company growth leads to the expansion of additional office space, all processes are analysed and revised, the planning departments are strengthened.


Opening of our office in Dresden, in the heart of “Silicon Saxony”, in order to be able to serve customers and partners from the high-tech sector even more directly and comprehensively with Hi-Tec Engineering on site.


Today, CRC is one of the leading architecture and engineering firms when it comes to complex planning tasks and building equipment for cleanroom buildings and laboratory buildings for industry and research.
