1Which Building Act (Zakon o gradnji) entered into force on 1 January 2026 and governs the current examination programme for electrical engineers in Croatia?
A.Zakon o gradnji (Narodne novine 153/13, 20/17, 39/19, 125/19, 145/24)
B.Zakon o prostornom uređenju i gradnji (Narodne novine 76/07, 38/09, 55/11)
C.Zakon o gradnji (Narodne novine 155/25)
D.Zakon o poslovima i djelatnostima prostornog uređenja i gradnje (Narodne novine 78/15)
Explanation: A completely new Zakon o gradnji was published in Narodne novine 155/25 in December 2025 and entered into force on 1 January 2026. Article 161 of the new Act expressly repealed the previous Building Act (NN 153/13 as amended). All state professional examinations administered by the Ministry (MPGI) in 2026 test candidates on the new statutory provisions.
2Under Article 5 of the Zakon o gradnji (NN 155/25), how many essential requirements for construction works (temeljni zahtjevi za građevinu) must buildings satisfy?
A.Six
B.Seven
C.Eight
D.Nine
Explanation: Article 5(2) of the Zakon o gradnji (NN 155/25) specifies eight essential requirements for construction works: 1. mechanical resistance and stability, 2. safety in case of fire, 3. hygiene, health and environment, 4. safety and accessibility, 5. noise protection, 6. energy economy and thermal properties, 7. emissions into the external environment, and 8. sustainable use of natural resources. This expanded the previous list of seven requirements.
3Which essential requirement for construction works was newly added as an independent requirement under Article 12 of the Zakon o gradnji (NN 155/25)?
A.Resistance to sound transmission and room acoustics
B.Emissions into the external environment (emisije u vanjski okoliš)
C.Accessibility for persons with disabilities
D.Protection against atmospheric discharge and lightning
Explanation: Article 12 of the Zakon o gradnji (NN 155/25) sets out emissions into the external environment (emisije u vanjsko okruženje) as the seventh essential requirement listed in Article 5(2). A structure and its parts must be designed, built, used, maintained and dismantled or removed so that over their life cycle they pose no risk to the external environment from the release of hazardous substances, microplastics or radiation into air, groundwater, sea water, surface water or soil; from incorrect discharge of waste water, flue gases or solid and liquid waste; from damage to the building including pollutant transfer by water into the foundations; or from the release of greenhouse gases into the atmosphere.
4Under the Zakon o gradnji (NN 155/25), what is the standard statutory validity period of a building permit (građevinska dozvola) issued by a county or city administrative department?
A.Two years from the date of finality
B.Three years from the date of finality
C.Six years from the date of finality
D.Eight years from the date of finality
Explanation: Under Article 79(1) of the Zakon o gradnji (NN 155/25), a building permit ceases to be valid if the investor does not commence construction within six years of the date the permit becomes final (pravomoćnost). Article 79(2) sets eight years for permits issued by the Ministry. Article 79(3) treats construction as commenced on the date the commencement of works is notified. Under the repealed 2013 Act the standard validity was three years.
5According to Article 89 of the Zakon o gradnji (NN 155/25), how many days in advance must an investor give electronic notice of the commencement of construction (prijava početka građenja)?
A.At least 3 days before commencing works
B.At least 5 days before commencing works
C.At least 8 days before commencing works
D.At least 15 days before commencing works
Explanation: Article 89(1) of the Zakon o gradnji (NN 155/25) requires the investor to notify the commencement of construction (or resumption of works) electronically, to both the building authority that issued the permit and the building inspectorate, no later than five days before construction starts. Article 89(2) requires the notice to state the permit reference, the contractor and the supervising engineer, and to enclose the certified setting-out study where one is required. The previous Act required eight days.
6Which statutory participant in construction (sudionik u gradnji) is responsible for ensuring that the electrical installation project complies with planning requirements and building regulations?
A.The supervising engineer (nadzorni inženjer)
B.The electrical project designer (projektant elektrotehničkog projekta)
C.The building auditor (revident)
D.The electrical works manager (voditelj elektroinstalaterskih radova)
Explanation: Under Article 19(2) of the Zakon o gradnji (NN 155/25), the designer (projektant) is responsible for ensuring that the designs they produce satisfy the prescribed requirements, and in particular that the designed structure meets the essential requirements and is designed in accordance with the location permit or with the building conditions prescribed by the spatial plan. Article 19(3) makes the designer's qualified electronic signature on the cover sheet the act by which that responsibility is assumed.
7Under the Zakon o poslovima i djelatnostima prostornog uređenja i gradnje (NN 78/15, 118/18, 110/19), what professional title is required to act as the responsible designer for an electrical installation project?
A.Diplomirani inženjer elektrotehnike bez stručnog ispita
B.Ovlašteni inženjer elektrotehnike registered with HKIE
C.Glavni inženjer gradilišta
D.Certificirani monter električnih instalacija
Explanation: Under Article 17 of the Zakon o poslovima i djelatnostima prostornog uređenja i gradnje, only a chartered electrical engineer (ovlašteni inženjer elektrotehnike) entered into the directory of authorised engineers of the Hrvatska komora inženjera elektrotehnike (HKIE) may act as the responsible designer (projektant) for electrical installations.
8Can an ovlašteni inženjer elektrotehnike act simultaneously as the supervising engineer (nadzorni inženjer) and the site manager (glavni inženjer gradilišta) on the same building project?
A.Yes, provided the investor provides written authorization
B.Yes, if the building gross area is less than 400 m²
C.No, the law strictly prohibits the supervising engineer from being employed by the contractor or performing construction works on that site
D.Yes, but only for simple electrical installations
Explanation: Article 24(6) of the Zakon o gradnji (NN 155/25) bars the supervising engineer and the lead supervising engineer from being an employee of the contractor executing works on the same structure. Article 126(2) point 1 makes a breach of that rule a misdemeanour for the supervising firm. The rule preserves the independence of professional supervision from construction execution.
9What is the mandatory electronic platform for maintaining the construction site diary (građevinski dnevnik) in Croatia under Pravilnik NN 131/21 and 68/22?
A.e-Dozvola
B.e-Građevinski dnevnik (eGD)
C.ISPU Lokator
D.ZIS Katastar
Explanation: Under the Pravilnik o načinu provedbe stručnog nadzora građenja, uvjetima i načinu vođenja građevinskog dnevnika te o sadržaju završnog izvješća nadzornog inženjera (NN 131/21, 68/22), the construction site diary must be kept electronically in the e-Građevinski dnevnik (eGD) system within the Information System of Physical Planning (ISPU).
10Who is legally responsible for entering daily data into the e-Građevinski dnevnik, and who is responsible for verifying and signing those entries?
A.The investor enters data; the building inspector verifies and signs
B.The site manager (glavni inženjer gradilišta / voditelj radova) enters data; the supervising engineer (nadzorni inženjer) verifies and signs
C.The designer enters data; the contractor verifies and signs
D.The health and safety coordinator enters data; the investor verifies and signs
Explanation: Under Pravilnik NN 131/21 and 68/22, the contractor's site manager or works manager enters daily records of site activities, weather, workforce, and installed equipment into the e-Građevinski dnevnik. The supervising engineer (nadzorni inženjer) is legally obligated to verify, sign, and record supervisory findings and approvals in the diary.
