In December 2020, igr was one of the few engineering offices in Rhineland-Palatinate to be awarded the RAL quality mark 961 in the execution area "Tendering and construction supervision for the trenchless rehabilitation of wastewater lines and sewers of all materials and nominal widths with the associated structures - ABS".

The igr was checked in advance by the "Quality Association for the manufacture and maintenance of wastewater lines and sewers e.V. | Güteschutz Kanalbau e.V.", with regard to the workflows and quality assurance processes. Furthermore, the special qualification of the employees was proven through many years of experience and corresponding training (e. g. "Certified sewer rehabilitation consultant", "Certified sewer rehabilitation manager", etc.).

Having been awarded this quality mark, igr is one of the leading specialist offices for tendering and construction supervision of sewer rehabilitation measures in Rhineland-Palatinate and Germany.  

Our certification will be your advantage: By the constant external monitoring of our work by the Güteschutz Kanalbau as well as the regular training of employees, your projects and concerns are always in the best hands.
