he following reference list shows projects with permanently installed elastomeric bearings:

58 storey building

Bedrock or hard soil

Weak clay 310 m

Sand or stiffer

clay 1025 m

1235 m piles

Excavation depth 23 m

Elastic element

A controlled mix of both deep andshallow foundation

When the elastic elements are compressed, the

total load from the building will be balanced betweenpile load and accumulated ground pressure.

The ground structure will be designed with full

soil-structure interaction, together with the bearingcapacity of the piles.
