There is provided a heavy construction installation method which does not need a secondarily transport in a construction field even if an installation position of a heavy construction is apart from a berthing position of a transport ship. A movable area where a ground plane is reinforced so that a heavy hoisting machine for installing a heavy construction in a building is movable is constructed so as to include a circle drawn around an installation position in the building with a maximum operating radius of the heavy hoisting machine relative to a weight of the heavy construction being as a radius, and a circle drawn around a loaded position of the heavy construction at a transport ship coming alongside a landing place with the maximum operating radius being as a radius.

According to an aspect of the present invention, an RFID tag has a long-distance communication RFID and a plurality of short-distance communication RFIDs. The RFID tag has tear-off lines for separating the short-distance communication RFID from the whole RFID tag, and when the short-distance communication RFID is separated, a loop-shaped antenna of the long-distance communication RFID is also cut up. And the RFID tag has an overall management identification code for identifying the whole tag before separation and a partial management identification code for identifying a partial tag after separation.
