Summary/Abstract: The paper presents specific aspects of the construction of the Kobilja Glava tunnel, which is being built as part of the I Transversal, section Vogošća-Sarajevo, with an emphasis on the use of additional support measures. Due to the poor characteristics of the rock mass – marl, significant subsidence was regularly monitored during excavation in the tunnel's tubes, both inside the tunnel and on the surface of the terrain. In specific geological sediments with poor geological and geotechnical characteristics, there is a need for the use of additional support measures, such as temporary invert, "elephant foot," support sail, etc., aimed at stabilizing the tunnel, preventing further movement, and preventing the encroachment into the designed profile of the secondary lining
