The contractual base gives our customers the guarantee of the agreed price. The controlling of the quality of the piece of work always takes place on more levels of leading, from the supervisor of the building to the company managing director. Especially the personal attitude gives our customers the feeling of safety during the whole period of cooperation. In 2004 the company introduced the system of quality management according to the norms STN EN ISO 9001:2015 and in 2016 the system of environmental management (ISO 14001:2015) and a system of work safety (ISO 45001:2018). Our aim is to permanently maintain and develop the introduced systems in terms of the requests of applicable norms, to examine them regularly, and based on that to look for other possibilities for their further enhancement.
