    In the last years the Finnish infra structure research has focused on the automated construction systems, like the two-phase ground improvement project. The first phase started in spring 2005 and ended in December 2007. The objective of the phase was to develop an interactive 3D model for deep mixing and piling including site investigation methods, data processing and analyzing methods which meet the needs of automated production management system. Another objective was to develop resistivity sounding method for deep mixing purposes. The first phase created readiness for the more economic, ecoefficient and better performance deep mixing method. By refining the 3D water content space created from the resistivity sounding results to the strength estimation of the deep mixing the amount of binder agent can be optimized along the columns. So the homogeneity of the deep mixing can be improved. This together with the more exact placement of the columns achieved by machine automation will improve the quality and performance of the product.
