Object-oriented modeling of construction operations for schedule-cost integrated planning, based on BIM

The study is aimed to develop a method to integrate time and schedule data of construction projects using object-oriented modeling. Although, many researchers have recognized the importance of data integration and have suggested methods to associate timeand cost-related data, the information models and methodologies developed to integrate time and cost information are not being utilized widely in daily practice. The reason for this includes that current construction management information systems do not yet provide the functionality to efficiently deal with time and cost information to better aid project managements. Therefore, an object-oriented modeling methodology based on BIM is suggested in this research, in which the time and cost data integration is achieved by parameterizing construction operations in objects. For observing applicability of the modeling method, a prototype has been developed using JAVA that this paper presents a discussion about implementing the integration model in the programming language as well.
