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 author of the project for the Zagreb Central Station building is a Hungarian architect Ferenc Pfaff, chief engineer of the State Hungarian Railways, who designs all the most important projects under their jurisdiction. In Croatia, he designed railway stations in Rijeka, Osijek, Karlovac and Zagreb. The building of the Zagreb Central Station was built in the period from 1890 to in 1892 and is located axially in relation to the axis of the chemical laboratory and the city park in the extension of the academic square. It is 186.5 m long, horizontally divided, with a relatively low pavilion-type facade opened by colonnades towards the Green Horseshoe. The facade is divided into three parts, of which the central one is the highest, and the two side wings are lower, with angular elevations. It is richly decorated with an inventory of neoclassical ornamentation and sculptural decorations consisting of allegorical compositions - the allegory of traffic is placed in the central gable, the allegory of cattle breeding and hunting are in niches at the height of the first floor, and on the attic of the rhizolite there are allegories of agriculture and industry. The sculpture was made by the company owned by Vilim Maršenko from Budapest in 1891/1892, and the works on the building were carried out by a company from Szeged, Iv. Milko.
The renovation and arrangement of the building of the Central Station in Zagreb included production of new facade plastering according to the existing one, making a new sheet metal shop, reconstruction of the roof and replacement of the pepper-tile cover, repair of damaged and replacement of exterior carpentry made of coniferous first-class wood and finishing the facade with a silicate coating.
