Abstract:
This paper presents time and cost planning in construction
projects using building information modeling (BIM) approach. The BIM technique can be incorporated into the time and cost planning process through several steps. At the beginning, a 3D model of the construction object is developed using an adequate modeling application. After that, the 3D model is imported into suitable BIM construction management
software. Thereupon, the project costs are estimated on the basis of quantities of required resources, consumptions,
production rates and unit costs. The project activities are then defined and linked to the construction elements of the 3D model as well as updated with allocated resources and costs. The activities with established durations are mutually connected together into a project network plan by taking into account relevant precedence relationships. The project duration
is automatically determined from the generated network plan. Finally, the BIM model of the construction object is completed
by upgrading the 3D model with defined scheduling and cost data. An application example is presented in the paper to demonstrate the advantages of BIM implementation in architecture,
engineering and construction industry.
