Abstract: Pre-compression by preloading is used to accelerate the consolidation settlement of a site ahead of construction so that post-construction settlement would be minimal. The principal aim of the technique is to remove the primary consolidation settlement anticipated under the proposed load with or without partial compensation for secondary compression so that post-construction settlement would consist of a small re-compression and secondary compression. In this paper, the scope of pre-compression is expanded to include partial removal of primary consolidation as a possible settlement management option. Modifications and simplifications are introduced into parameter estimation for design to deal with pre-compressions intended to remove any degree of the primary consolidation and those that go beyond the primary consolidation stage. This provides foundation engineers the flexibility to evaluate different pre-compression load and duration options under different settlement regimes and their implications. A numerical example is used to demonstrate and verify the modifications.
