A structural engineering consultancy, founded in Zagreb in 2011. After the 2020 earthquakes our engineers inspected damaged buildings as volunteers; since then, seismic retrofit has been a large part of our work.
Six civil engineers: licensed civil engineers (ovlašteni inženjeri građevinarstva), a project manager (IPMA Level C), a permanent court expert (stalni sudski vještak) and health and safety coordinators. We work under a licence from the Ministry of Culture and Media to work on cultural property and have a long-term collaboration with our partner firm JAN-ING d.o.o.
The firm is founded in Zagreb: design, supervision and expert opinions.
Denis Bolić joins and cooperation with JAN-ING begins; after the 2020 earthquake, inspections of damaged buildings followed by more than a hundred buildings in the renovation programme.
A growing team and larger projects: structural renovation of cultural properties and construction supervision on larger sites.
