Frequently Asked Questions

What is an 'ovlašteni inženjer građevinarstva' in Croatia?

An ovlašteni inženjer građevinarstva is a chartered civil engineer who has passed the state professional examination (stručni ispit) administered by the Ministry of Physical Planning, Construction and State Assets (MPGI) and is registered in the directory of authorised civil engineers of the Hrvatska komora inženjera građevinarstva (HKIG). Only chartered civil engineers can serve as chief designer (glavni projektant), project designer for civil/structural projects (projektant), or supervising engineer (nadzorni inženjer) for construction works under Croatian building law.

Who administers the civil engineer professional examination in Croatia?

The examination is administered by the Ministry of Physical Planning, Construction and State Assets (MPGI), not by the Chamber. The examination commission is appointed by the Minister. Candidates submit their application on form SIG-1 with proof of graduation (300 ECTS), proof of two years of relevant work experience, and payment of the state examination fee. Upon successful completion, MPGI issues a state certificate (Uvjerenje o položenom stručnom ispitu).

What is the structure of the official Croatian examination?

The official examination is oral, conducted in Croatian before the Ministry's examination commission in Zagreb (Article 29 of NN 129/15). The examination covers three mandatory areas: 1. Osnove tehničke regulative (building act, spatial planning, participants, permits, ZUP), 2. Regulativa zaštite osoba, okoliša, kulturnih i drugih materijalnih dobara (fire safety, occupational safety, environment), and 3. Tehnička regulativa gradnje (Eurocodes, structural design, geotechnics, concrete/steel/masonry structures, and construction products).

What happens if a candidate fails one subject on the examination?

Under Article 33 of the Pravilnik (NN 129/15), a candidate who fails at most one examination subject is entitled to sit a supplementary examination (popravni ispit) in that subject between 30 and 60 days following the examination. The fee for the supplementary exam is €39.82 (30% of the full fee). If a candidate fails two or more subjects, the entire examination must be retaken no earlier than 30 days after the sitting.

What are the major 2026 regulatory changes affecting the examination?

Effective 1 January 2026, the new Zakon o gradnji (NN 155/25) and Zakon o prostornom uređenju (NN 155/25) replaced the 2013 acts. Crucial changes include eight essential requirements for construction works (adding environmental emissions as Article 12), extending building permit validity to six years (eight years for Ministry-issued permits), mandatory electronic site records (e-Građevinski dnevnik), and updated lists of technical standards published by MPGI as of 1 January 2026.

How does this practice bank relate to the official Croatian examination?
