Budapest has a long tradition in building underground lines: the
Millennium Underground Railway is the second-oldest underground line in
the world. The construction works of the fourth metro line in Budapest
started in 2004. This paper gives basic facts about the new metro line,
and reports on the damage prediction project concerning urban buildings
which was done at the Budapest University of Technology and Economics,
Department of Structural Engineering. The methods applied for the
assessment of expected building damages due to underground tunneling as
well as the results of this project and their utilization are briefly
introduced.
