The Costs of the Construction of Motorways and Drilling Tunnels

Summary/Abstract: We analyse the variability of the costs of the construction of motorways in Europe. Attention is paid to the formation of the cost of motorway sections run in mountainous areas and in tunnels. A method for calculations is proposed and the costs of building roads with tunnels in Slovenia and in Poland are compared. The paper presents the developed authorial cost estimate for the excavation of the tunnel in the stretch of the expressway S7 Naprawa - Skomielna Biała and examines the value of individual works presented by the 6 bidders who participated in a restricted tender. Conclusions are focused on the assessment of the cost level of road construction in Poland in the context of the expenditures incurred in the European countries.
