Revision of Design Documentation represents the third and integral part of the total scope of “Divel” activities, more specifi cally: revision of designs for motorways, revision of designs for main and regional roads, as well as revision of designs for structures (bridges and tunnels). The most signifi cant reference we can boast of as of today is revision of the Main Design of the Motorway, including Bridges and Tunnels as well as the 3-level Butila Interchange, the junction between the Motorway at Corridor Vc, Sarajevo Bypass (Jošanica – Vlakovo) and the city expressway Butila – Babin Kuk (east entrance to Sarajevo from the direction of Višegrad and Pale).
