摘要：In this paper, WBS-based hierarchical classification and its DB modeling structure of all construction information for apartment house are proposed. The proposed WBS-based construction information classification system divide all construction information of apartment house into 4 hierarchical levels that are construction zone classification, building classification, work classification, and work item classification. These hierarchical construction information are DB modeled using a relational data model. The computer aided processing of the construction management by this DB modeling of the construction information is possible. The proposed WBS-based hierarchical classification and its DB modeling structure will be applicable to an effective and scientific cost estimation system
