Our commitment

We are committed to supporting our clients through every stage of their projects. Our well-established work processes allow us to take care of all the details of the project we are executing. This way of progressing helps in achieving our objectives in terms of time and budget, and sometimes even to beat the deadlines.

Quality and safety on all our sites are our priorities. Therefore, Antagon’s developed it’s own quality assurance program. This program is constantly adapted to meet the specific requirements of the projects we are delivering.

In 2008, the management committee decided to take the necessary steps to obtain the ISO certification. Thanks to the programs already in place and to the commitment of the employees and their team work, Antagon’s quality control system was ISO 9001 certified for several years.
