Divel d.o.o. Sarajevo - civil engineering services - design, revision, supervision

DESIGN

Divel has compiled main designs for various motorways and freeways with the total length of 87.5 km, including designs for 74 bridges (with the total length of 12,100 m), designs for nine tunnels with a total length of tunnel barrels of over 24 km (tunnels “Suhodol” 2,930 m, “Vijenac” (1. Mart) 2,970 m). Furthermore, “Divel” has compiled designs for 6,800 m of support and lining structures, as well as for 70 other structures (underpasses, overpasses, junctions, hydrotechical structures and other) and traffic design of the Motorway A1 (Kakanj - Jošanica).

Meaningful engagement of the company is best recognized in projects of construction, modernization, reconstruction and rehabilitation of the Main and Regional Roads, a number of bridges (66 of them), tunnels (15 tunnels and galleries) and in rehabilitations of landslides and rockslides. Our reference list is additionally complemented by the realized traffic projects for over 650 km of the main roads in F BH.

Among many and varied projects, we could especially single out the main design of the main road leading from Neum to Stolac (said road is 37 km long and connects Neum with the inland), as well as reconstruction and rehabilitation designs for roads in total length over 830 km. As for the network of main and regional roads, 66 bridge designs, 16 tunnels and galleries’ designs were compiled. Regarding large scale and demanding structures, we could highlight the following designs: the bridge over Jablaničko Lake (550m long), the bridge over Čemerno mountain pass (400 m long) and tunnel “Karaula” located at Tuzla - Sarajevo road (950 m long).

Stabilization designs, rehabilitation designs and designs aimed at improvement of service level of the existing tunnels are singularly complex and demanding projects. Regarding tunnel construction, Divel has compiled designs for 9 tunnels, among which the most significant are considered to be tunnel “Vranduk 2” at the road M-17 section Doboj – Lašva and tunnel “Crnaja” at the road M-17, section Sarajevo – Jablanica.
