Construction of excavation containment works for the expansion of Teatro alla Scala on Via Verdi.

The intervention includes the installation of a berlin wall with perimeter micropiles, anchored with four orders of anchors, a bottom plug created with cement injections, and metal contrast works. The perimeter berlin wall, given that the excavation is about 4 meters below the water table, has been waterproofed with the creation of a jet grouting barrier.

A total of 7,000 meters of micropiles, 5,000 meters of anchors, and 3,500 cubic meters of soil treated with cement injections have been completed.
