To make it possible to correspond to the weight during preparation of a structure and also correspond to significant irregularity of the mound surface even though a value of mound leveling acuracy is high and a mat member is made thick when installing an ocean structure on a foundation mound.
When arranging a mat member 10 and building a structure 30, a hole 11 made in a mat is drilled up with a filler 12 thereby building a member for supporting a load, thereby preventing the deformation of the mat by the load in the middle of building the structure. Thus, the filler 12 is removed when removing the structure, a remaining hole portion is greatly deformed by the irregularity of the mound but by forming the mat 10 very thick, the significant irregularity of the mound can be eliminated and the structure can be retained.
