A study on the centralized building construction information management using a project database system(PDB)

This paper describes the development of a project database system (PDB) which is one of the integrated construction system, in order to manage the building construction information. This system's data model consists of building component attribute, progress control information, construction equipment, standardized work process unit including subcontractors information. This database system allows us to automatically access each application data and enables to collect laborers' work record data or material handling time to analyze the work schedule control. The purpose of the system is to implement high productivity and quality through a collaborative and concurrent work tools. By promoting such information-based construction, we will create the new production system in construction.
