Construction is an activity that has left a lasting legacy to humanity that we have the opportunity to admire again and again.
Inspired by this very fact, ING-GRAD was founded as a construction company whose activities include specialized works comprised of: restoration and reconstruction of monumental heritage of exceptional historical and artistic significance.
In more than 35 years of work on the restoration and reconstruction of the monumental heritage, we have been using all the advantages of modern construction methods, but also applying unique knowledge based on the techniques, skills and recipes of old crafts.
Most buildings of cultural or architectural heritage are brick buildings built of stone or brick wall elements connected with mortar, usually found in poor condition due to their age and inadequate maintenance. Therefore, before the renovation and final arrangement, it is necessary to carry out constructive restoration. The complexity of the historical buildings restoration requires the incompatibility of traditional and new materials and respect for their original existence, which is why the use of reinforced concrete is not recommended. The most favourable technique for repairing and strengthening such constructions has proved to be injection, i.e., stabilizing and closing cracks in damaged walls by injecting special injection compounds, applying reinforced cement or epoxy coatings on one or both sides of the wall, and pre-tensioning the walls.
Roofs of monumental heritage buildings are usually wooden roofs with different types of covering, depending on the tradition of the climate in which the building is located. The reconstruction of such wooden roofs implies the replacement of individual elements or the complete structure with new wood, most often made of Slavonian oak or conifer, and the replacement of the covers.
The renovation and reconstruction of the building includes the renovation of the external facade, the execution of profiles and stone plastic, the production of wooden joinery and everything that includes the restoration of the historical appearance and original condition. It is done according to conservation guidelines, which is why the restoration and reconstruction of the building is longer and requires specific materials, works and methods of execution.

The buildings were built as a barracks complex from 1898 to 1899 based on the construction project from construction tech. adviser Milan Lenuci and architect Janko Holjac and represent an outstanding example of well-designed barracks buildings. The buildings are a protected cultural asset as part of the cultural and historical urban complex of the city of Zagreb based on the decision of the Ministry of Culture.
Since 2006, complex has belonged to the Zagreb Archdiocese and housed the Croatian Catholic University. Complete renovation of the campus of the Croatian Catholic University includes 4 buildings: 244, 244 A and 244 J, 244 K.
Building 244 has a wooden load-bearing structure of the roof, which is replaced by a new one made of wood and steel, which further strengthens it and increases the utilization of the attic space. The volume, geometry, height and shape are maintained, and it is planned to replace the cover with eternit-fiber cement boards that do not contain asbestos.
Building 244 A is a free-standing building with a rectangular floor plan. With the planned reconstruction, the building will be intended for scientific institutes and research units of the Croatian Catholic University. The addition of a fully buried underground technical block is also planned. An underground connecting corridor will connect the existing building and the new buried technical block into a whole.
Building 244 J and Building 244 K have a regular, almost rectangular shape. The buildings are oriented north-south along their longer axis. The buildings have five floors - basement, ground floor, two floors and an attic. Reconstruction of buildings within the complex of the Croatian Catholic University is planned. The position of the buildings does not change in relation to the existing condition.
