Organisation scheme

At ZAG, investigations and tests are carried out in laboratories and sections designed in accordance with the characteristics of the products. In terms of their activities, laboratories are grouped into departments.

ZAG has 253 employees, of which 71 are doctors of science (1. januar 2024).


To celebrate the 70th anniversary of the Slovenian National Building and Civil Engineering Institute (ZAG), we have issued a brochure Knowledge that leaves a mark in Slovene and English.

The brochure consists of two introductory chapters, about ZAG in 2019, by Director Assist. Prof. Aleš Žnidarič, and its scientific and research activities, by Assoc. Prof. Andraž Legat, and eight selected topics and presentations of ZAG units.
