Claim:
A building method of assembling an inspection scaffold and a large component for a boiler, the inspection scaffold having a plurality of scaffold supporting beams and a plurality of scaffold components, comprising: simultaneously assembling the inspection scaffold with the large component at a ground surface, simultaneously assembling at the ground surface comprising: (a) assembling the plurality of scaffold supporting beams to a plurality of wires suspended from a wire attaching fixture, the plurality of scaffold supporting beams being assembled between spaces of the large component while the large component is suspended from a large component supporting beam at the ground surface; (b) assembling the plurality of scaffold components sequentially to a lower surface of the plurality of scaffold supporting beams; (c) coupling the plurality of scaffold supporting beams to a horizontal member of the large component, after a required number of steps of the plurality of scaffold components are assembled; (d) raising the large component with the inspection scaffold by a lifting means to a main support member; and (e) coupling the large component with the inspection scaffold to the main support member.
