1. A fabrication method of a plant facility, which is to be provided in a plant configured to perform fluid treatment, and includes a pipe through which fluid is allowed to flow, the method comprising the steps of:
fabricating a plurality of modules at a fabrication yard differing from an installation site of the plant facility, the plurality of modules including:
a plurality of pipe spools that configures the pipe;
frame structures, each configured to support the plurality of pipe spools; and
hook up surfaces, formed on side surfaces of the frame structures,
wherein end portions of the plurality of pipe spools are positioned on the side surfaces of the frame structures, the end portions of the plurality of pipe spools are exposed on the hook up surfaces, at least a part of the end portions of the plurality of pipe spools are protruded from the hook up surfaces, and the plurality of modules is configured to be coupled to each other in a horizontal direction via the hook up surfaces to form the plant facility;
transporting each of the plurality of modules manufactured at the fabrication yard to the installation site of the plant facility;
calculating, in advance, for the each of the plurality of modules, expansion and contraction amounts of the plurality of pipe spools caused by a temperature difference between a temperature at the fabrication yard before start of transportation of the each of the plurality of modules and a temperature at the installation site after the transportation of the each of the plurality of modules;
installing the each of the plurality of modules while performing at least one of the steps of:
adjusting an installation position of the each of the plurality of modules with respect to a foundation toward a direction to cancel out the expansion and contraction amounts of the plurality of pipe spools, the foundation being arranged in advance at the installation site so that the hook up surfaces to be coupled to each other of the plurality of modules are allowed to be adjacently opposed to each other; and
adjusting a position of an end portion of at least one pipe spool of the plurality of pipe spools supported by the frame structures toward the direction to cancel out the expansion and contraction amounts of the plurality of pipe spools; and
connecting end portions of the plurality of pipe spools opposed to each other of the plurality of modules having the hook up surfaces arranged adjacently to each other to form the pipe, to thereby manufacture the plant facility.
