The invention discloses a data structure which associates working contents of a subproject, a subdivisional work and the like of construction engineering specified by national regulations with a comprehensive construction management knowledge base. A comprehensive construction management knowledge base data structure comprises a data structure, which is associated with working contents of the subproject, the subdivisional work and the like of construction engineering specified by the national regulations, of an index file, and a data structure of information bases of construction specifications, construction process standards, construction quality acceptance specifications, data, safety civilized construction specifications, national compulsory provisions, prevention and control of construction quality common faults, construction technology, safety disclosure, environmental protection and the like which are associated with working contents of the subproject, the subdivisional work and the like of construction engineering specified by the national regulations. In construction engineering project management software, working contents of the subproject, the subdivisional work and the like of construction engineering are organically linked with the comprehensive construction management knowledge base for construction engineering by the data structure, so that great convenience is brought to the project management of construction engineering, the project construction information management level of construction engineering is increased practically, and the management efficiency and management level of a construction enterprise are further improved practically.
