In a ground improvement work, there are cases in which a design must be changed due to problems such as inconsistency in the position of buried objects and discrepancy in the ground conditions. In these cases, advanced management methods of work progress control are required to properly evaluate the effect of ground improvement. This research examined the applicability of geophysical exploration to visualize the ground improved by chemical grouting. The laboratory model test and the field test at construction site were performed using the P-wave amplitude attenuation tomography. These tests demonstrated that the P-wave amplitude attenuation can recognize the change in ground condition due to chemical grouting. Besides, we discussed the method in which construction information and geophysical exploration result were integrated by BIM/CIM.
