Forensic engineering

The Department of Forensic Engineering works within the Directorate of Judicial Expertise of Hungarian Institute for Forensic Sciences.

The main duty of the department is to fulfill an official assignment in a case where a law allows or obliges the conduct of the probationary procedure ex officio, or (Eg civil, criminal and administrative matters) or, depending on its free capacity, based on a mandate, to carry out judicial expert activities, to produce judiciary expert opinions on the laws, regulations, instructions, and professional methodology.

Within the Department of Forensic Engineering, the judicial experts work in four main areas. The main areas are the following:

  • road vehicles and transport
  • architecture
  • IT
  • speech and voice recognition

The experts can do the required measurements and test on-site. The department has the necessary personal conditions and technical background to perform the tasks. The experts of the department carry out their expert tasks in territorial institutes operating at several points of the country. The experts engage in complementary activities in areas of their competence to provide the professional background needed to produce appropriate, well- founded expertise.
The department’s experts are members of several domestic and international organizations:

  • Hungarian Chamber of Judicial Experts (MISZK)
  • Chamber of Architects
  • Chamber of Engineers
  • EVU (European Association for Accident Research and Analysis)

Two of the experts specialized in road traffic a have a certificate issued by IQ-CERT Quality Assurance and Certification Institute certified according to DIN EN ISO / IEC 17024: 2012.
