A method for laying a plurality of objects to form a polyhedron, the method including: determining a pattern for each of a plurality of courses constituting the polyhedron based on the type of the polyhedron and the frequency of the polyhedron; determining a unique group from each of the plurality of courses; determining members of the unique group and orientation of each the member of the unique group from the plurality of objects; and laying the plurality of objects as determined from the above steps to form the polyhedron.

A method of constructing a dome-shaped roof on a cylindrical tank body includes processes of assembling roof beams into the tank body in a radial shape to form a structural skeleton unit of the dome-shaped roof, attaching wheels to front end portions of the roof beams and causing the wheels to abut an inner surface of the tank body in a state in which the wheels are able to roll in a vertical direction, lifting the structural skeleton unit by jack-up units installed at an upper end side of the tank body and causing the wheels to roll along the inner surface of the tank body to travel upward, and directly or indirectly attaching and fixing the structural skeleton unit to an upper end portion of the tank body after the structural skeleton unit is lifted to the upper end side of the tank body.
