SECO Group

SECO Group operates in the Benelux region, where it was created in 1934 (Brussels) but has grown steadily with offices in Belgium (Head Office), Luxembourg, The Netherlands, Poland, France and Vietnam and assignments on projects worldwide.

SECO Belgium - Head office

Our company SECO was established in 1934, on the initiative of Professor Magnel and François. SECO became the first independent and neutral technical partner of the construction industry, set up to enhance global quality and prevent risks on construction projects. Our main concern was – and still is – to bring you innovative solutions. We have also been the pioneers in the development of European norms and use of materials.


In addition, our 35-year partnership with BCCA, the Belgian Construction Quality Association, has allowed us to play a significant role in the certification processes.


SECO Group has 3 offices in Belgium. The head office is located in Brussels and two satellite offices in Ghent and Namur.

  • Ghent: Kortrijksesteenweg 90, 9830 SINT-MARTENS-LATEM
  • Namur: Chaussée de Liège 624, Orion Business Park building A, 5100 JAMBES

SECO Poland

SECO Polska, the Polish branch of SECO, was established in Warsaw in July 2005. Our goal is to deliver technical excellence and to provide technical support to investors and developers. Initially, technical inspection services and advisory services were our main activities in Poland, based on the direct transfer of our know-how from our Brussels Head Office. Over the past twelve years though, SECO Polska's office in Warsaw has expanded thanks to our local engineers who provide their know-how to implemented projects. In addition to technical inspections, SECO Polska also provides a wide range of services to investors and developers, such as:

  • Management of design processes;
  • Management of administrative procedures at the stage of investment preparations;
  • Quality supervision;
