The application of prestressing systems SPB and SPB SUPER in the construction of significant infrastructure facilities includes bridge structures on the southern branch of Corridor X – highway E-75 (five bridge structures, 402 mounting brackets), bridge structures and overpasses on the eastern branch of Corridor X – highway E-80 (five bridges and 3 overpasses), overpasses and access bridge structures over the DTD canal during the construction of Boulevard Europe in Novi Sad (315 prefab girders), approach structures of the bridge over the Sava River near Ostružnica (Belgrade Ring Road), bridge over the Kolubara River near Obrenovac and the bridge over the railway (highway E-763), the roof structure of the Belgrade Arena (span 132.7 x 102.7 m), the Aval tower (height 204.57 m, AB structure 135.65 m, steel structure 69 .92 m).

Rehabilitation of buildings using SPB and SPB SUPER prestressing systems was carried out on the arched road bridge over the Tisza river near Titel (built using the IMS prestressing system), as well as on overpasses on highways and other state roads.

Prestressing technology was also applied to the construction of a special structure for the needs of static testing of piles on the Čortanovci viaduct, the overpass near Beška and in the Subotica area as part of the construction of the high-speed railway Belgrade – Subotica – Budapest.

Production and delivery of materials and equipment, calibration of equipment, training of personnel and control and supervision of the operation of plants for adhesive prestressing was carried out for a large number of plants for the production of concrete prefabricated elements in the territory of Serbia and Bosnia and Herzegovina.

Carrying capacity testing, weighting, control and monitoring during the installation, injection and weighting of prestressed geotechnical anchors were performed on numerous infrastructure facilities: on the construction of retaining walls and slope stabilization on the construction project of the southern branch of corridor X through the Grdelica Gorge (7,500 prestressed geotechnical anchors), on the eastern branch of corridor X, on slope stabilization within the construction of the Arilje dam and reservoir – Svračkovo profile, on the construction of a retaining wall for the needs of the expansion of the Bajina Bašta reversible hydro power plant complex, within the construction of the coastal fortification of the Kostolac pier, for the needs of landslide rehabilitation and protection of slopes and foundation pits for the need for the construction of mini-hydro power plants on the river Lim near Priboj and Ibar near Raška, for the purposes of stabilizing the slopes and retaining walls on the tunnel Straževica and Beli potok (Belgrade Ring Road).

More recent references to the lifting of structures include the lifting of the complete upper machine above the middle support of the road bridge structure over the Jadar River near Loznica and the lifting of reinforced concrete vaults in the crypt of the Church of Saint Sava in Belgrade.
