The condition of a seabedand the condition of tidal currents near the seabedare investigated in advance to examine the number of filter units (FUs)and the position where the FUsare to be installed. Then, pilesas a base of a foundation are provided so as to be supported by a bearing layer. A plurality of FUsare installed in close contact with each other between the seabedand each pile. Then, a formworkfor a base slab portionis installed on the upper ends of the piles. Concrete is placed in the formworkto form the base slab portion. Then, a toweris fixed to the upper end of the base slab portion

At a location where unevennessis present, the condition of a seabedis investigated in advance to examine the respective numbers of large filter unitsand small filter unitsto be used, and the position where the large filter unitsand the small filter unitsare to be installed. Based on the investigation result, the small filter unitsare installed on the bottom of the unevenness. The large filter unitsare installed on the upper surface formed by the installed small filter units, and are leveled so that the upper surface formed by the installed large filter unitsbecomes flush with the seabed
