To reduce the burden of managing materials and equipment for use in building equipment.SOLUTION: In a
management system, a portable terminal selects one work process from among a plurality of work processes for a material or equipment which is attached to building equipment to function as a part of the building equipment, acquires identification information of the material or equipment from an identification member attached to the material or equipment, transmits information indicating the selected work process, in association with the acquired identification information, to a
server device. The
server device is configured to: store BIM data indicating arrangement of the material or equipment; specify, every time receiving, from the portable terminal, past registration data including the identification information and work processes of the material or equipment, a work process of the material or equipment in the BIM data; reflect work process completion information of the specified material or equipment in attribute information of the specified material or equipment in the BIM data; and sequentially reflect completion information of each of the work processes in the BIM data.SELECTED DRAWING: Figure 10
