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.

Today's building of the Main Guard was built in 1729 on the north-western part of the Holy Trinity Square in the centre of the Osijek Fortress. On the ground floor, the building is open with a portico with wide semi-circular arches. The Brožan House was named after one of the first owners, it is located on Jurja Križanić Square and is one of the oldest buildings there. It was built as a one-story residential building with one row of rooms open to the street, while there were probably no windows on the courtyard side. On the ground floor there was a kitchen, one larger room and a storage room, and there were three bedrooms on the first floor. The special feature of this house is its circular staircase, which is located in the courtyard. The house has a high baroque style roof covered with pepper tiles. During its history, it has undergone many reconstructions and additions, which were often not in accordance with the original appearance of the building.
For the needs of the Archaeological Museum, the construction interventions on both buildings were preceded by conservation-restoration works and research, geomechanical and structural research, as well as work on the protection of the buildings and strengthening of the structure. Since 2006, construction, tradesman, installation and conservation-restoration procedures have been carried out on the mentioned buildings for the purpose of reconstruction of existing and addition of new parts of buildings and reconstruction of the roof dome.
