Financial analysis of the change of construction tehnology used for viaduct Dobruša

摘要

The subject of the thesis is the cost analysis of the change in construction technology used for the viaduct Dobruša on the motorway section Vrba - Peračica. In the project for the tender, which was prepared by the investor, the viaduct Dobruša was designed as a continuous beam over five spans with a maximum of 72.5 m in length, constructed using balanced cantilever method. After the technology was changed, the viaduct was designed as a continuous beam over six spans with a maximum of 57.9 m in length, constructed using incremental launching. The thesis describes the contractor's procedure used to modify the technology of the construction according to the contract terms. Our objective is to present the results of the change in construction method, which had a positive impact on the deadline, the progress of the work and the price of the construction.
