Technical Paper: Ground improvement for the foundation of a high-rise building

Luca Mancinelli and Martino Gatti, Rocksoil. This paper was first published in GE’s April 2013 issue.


For the construction of a new office for the Lombardy region administration in Milan, Italy, a 161.3m high concrete tower with 39 floors and two basement levels, a ground improvement solution was proposed and implemented. This building constitutes the new headquarters for the personnel
of the Lombardy region local authority, who were originally in different locations.

The objectives of this intervention were to increase bearing capacity and reduce settlement under the high rise building load. In a geotechnical context consisting of sand and gravel with water and a 3m silty layer, with low Young’s modulus, at a depth of 30m from the surface, jet-grouting technology was chosen. After a preliminary phase of insitu and laboratory tests for the definition of the geotechnical model, columns were created using different sets of operational parameters and then examined to establish the most appropriate working procedure.
