Between 2011 and 2014, we worked as a general contractor for Continental Hungary on several consecutive and parallel projects. Our assignment was extremely complex: during the 3-year period, we extended the client’s office building “C” in Budapest by 1600m2, built offices and other social functions, and expanded the high-bay warehouse (1200 m2) and the automotive electronics production area (4200m2). The main challenge of the work in the production area was to meet the very strict specifications for the manufacturing process, which had to be carried out in a non-stop automotive electronics plant, in a dust-free environment and with continuous over pressurisation.
