temporarily fixing an intermediate tank roof onto an inner tank roof to form a connected roof body;
installing a guide side plate having a predetermined height around the connected roof body;
performing a sealing process between an outer peripheral edge of the connected roof body and an inner face of the guide side plate to form a sealed space, and supplying air to the sealed space to air-raise the connected roof body; and
forming at least a part of an outer tank roof on the intermediate tank roof of the air-raised connected roof body, and installing an outer tank side plate around the guide side plate.
