On this construction site in Munich a gap between two existing buildings will be closed and a new residential building with an automatic underground car park will be constructed. An approx. 8.5 metre deep excavation pit has to be constructed for the underground car park. The material in the ground is gravel or conglomerate. It is so firm that it cannot be torn with an excavator bucket.  Because of the proximity to adjacent buildings, the use of a hydraulic hammer to break out the material is not possible. The resulting vibrations could damage the existing building fabric. The noise pollution would also be too high for the residents. In order to be able to loosen the excavated material, only the use of an excavator mounted milling machine is possible. This also has the advantage that it is possible to mill right up to the walls of the outbuildings without generating vibrations.  An ER 600 is used on a CAT 314 crawler excavator. In this combination, a milling capacity of 12 to 15 cubic metres per hour is achieved with a material strength of 15 to 20 Mpa, whereby the outer walls of the outbuildings have to be milled very carefully.
