Construction projects for chemicals, energy and logistics
We plan, construct, renovate and maintain industrial buildings safely, reliably and with many years of experience. Our focus is on complex projects in sensitive industrial environments such as chemical parks, power stations, refineries, energy infrastructure and large logistics sites.
Of our more than 750 employees, around 60% are construction site personnel, whom we train regularly. On average, we devote 2% of annual working hours to training.
For whom and why?
We generate more than 90% of our turnover in the chemical, energy and specialised logistics sectors. Customers from these sectors trust in our experience because we construct complex industrial buildings reliably and safely.
