An apparatus for supporting arrangement of operation areas layout includes: a storage unit that stores therein data on a position, a shape, and a use period of each operation area which has already been arranged in a prescribed site; a display control unit that references the data stored in the storage unit and makes a display unit display a top view illustrating arrangement of the operation areas at a given point of time on a temporal axis; and an operation areas layout arrangement processing unit that receives an input of a data on a position, a shape, and a use period of an operation area to be added into the prescribed site, references the data stored in the storage unit, and, if the received and added operation area is not determined to interfere with other already-arranged operation area, stores the data on the added operation area in the storage unit.

Apparatus, method, program, and recording medium for supporting arrangement of operation areas layout

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.

Heavy construction installation method

A carry-in ready period calculation part calculates a candidate of a carry-in ready period which is a period during which a carry-in operation can be conducted and outputs the candidate in an output part so as to make entire construction works efficient. The calculation is performed based on a site arrival time schedule which is a time schedule showing when a carry-in target equipment arrives at a site, a temporary placement time schedule which is a time schedule showing when the equipment arrived is temporarily placed, and a construction time schedule of a building in which the equipment is carried.

System for supporting carry-in operation planning

An operation simulation system for plant construction, having operating expense calculated based on crane type determined by a command input; the expense to construct foundation calculated based on the foundation placement on which the determined crane is put; the operating expense calculated based on a period during which an operation is carried out; the expense to temporarily place the installation object calculated based on the specifications of the installation object before the installation; the installation operation expense calculated based on an installation milestone reflecting a due date of the installation object; the total necessary expense calculated based on all the expenses calculated; the total necessary expense is analyzed and evaluated; and the command input is adjusted by reflecting the results of an evaluation analysis so that the value of the command input falls in range of the set values in the specifications held by the corresponding setting apparatus.
