The subject of this paper is a comparative analysis of the alternative solutions for the construction of the supply tunnel section of HPP "Dabar" from km 4 + 272.54 to km 12 + 125.0 with the application of TBM technology, milling machines technology and combinations of TBM technology and milling machines. Hydraulic tunnel of the HPP "Dabar" is a tunnel under the pressure with a length of 12125.0 m, which will conduct water from the reservoir Nevesinje to the machine building of the hydropower plant "Dabar" in Dabarsko polje (Republic of Srpska, Bosnia and Herzegovina). Four different construction alternatives of the mentioned tunnel section were analysed: use of milling machines, use of Gripper TBM, use of Double Shield TBM, a combination of Gripper TBM and milling machines.
