The traditional igr staff meeting was held on the third Friday of the New Year in Rockenhausen.

In 2014 igr was awarded, through a competitive tendering process, an American armed forces framework contract (IDIQ - Indefinite Delivery Indefinite Quantity). These framework contracts are put together without a precise description of the work contracted (Indefinite Delivery) or a definition of its scope (Indefinite Quantity). Every year the US Defence Department issues such programmes, which allow the US users to award these framework contracts and to implement individual projects on this basis.

In the last three years the city of Sisak and its suburbs have suffered extreme flooding due to heavy rainfall events. Three rivers, the Sava, the Kupa and the Odra, meet in the suburb of Staro Pracno.

Even with 30 years as a successful engineering company behind us, we must constantly ask whether we are prepared for the tasks that lie ahead in the next few years and decades. For us, this is no empty cliché, but rather we are putting into practice, with great commitment, the concept of making ourselves fit for the future.

On the 30th of September 2015, igr has been honored for its 25 year membership at the UVP-Gesellschaft e.V. (society for reviewing environmental sustainability). The society is active in the scientific-methodological advancement of environmental sustainability review on national and European basis.
