Abstract: “The top-down method has various advantages in the building of deep basements, as demonstrated by the efficient construction of the new San Martín Market in San Sebastián (Spain). The foundations of the building involved highly complex features, due to the prevailing water table and the need to embed the structure into highly resistant limestone rock. Continuous diaphragm walls were constructed about the site perimeter, using an innovative combination of trench cutter and hydraulic grab, and large diameter piles connected to vertical columns were installed from the surface”.
