The downtown building was built in 1910 and sustained major damage in the 22 March 2020 earthquake.
"We are one of the first institutions to have embarked on a seismic retrofitting project in Zagreb and are proud of it," Hina's director Branka Gabriela Vojvodić said.
She expects the seismic retrofitting to take about a year and is confident that funds for the complete reconstruction of the heritage building will be secured in the foreseeable future.
Vojvodić thanked the Culture Ministry for the support and everyone at Hina who worked on the reconstruction project.
The seismic retrofitting will be done by Teh-gradnja, a company specialising in the reconstruction of heritage buildings.
Last Friday, Vojvodić and Teh-gradnja director Ilija Beara signed a contract for the HRK 10 million works. The money was secured via the Culture Ministry as part of measures for the protection of the cultural heritage damaged in the earthquake.
According to experts, Hina's building will be one of the sights in downtown Zagreb after the complete reconstruction, Vojvodić said.
During the reconstruction, Hina will continue to operate in rented premises, while a majority of its staff, since the earthquake, continue to combine field work and work from home.
