    Analysis of Building Information Modeling (bim) Performance Using Big Data From a Construction Project
    (01. Izmir Institute of Technology, 2023) Bostan, Berkay Batuhan; Çavka, Hasan Burak
    This study aims to propose a systematical approach for evaluating BIM performance from a main contractor's perspective based on big data from a construction project. Retrospective case study is used as the research approach. Data is collected through interviews with the main contractor firm, and data from the logged project information in project databases including ACONEX and Microsoft Excel files. A framework containing performance metrics, specifically tailored to evaluate BIM performance based on big data, is developed from the combined analysis of literature review, interviews with main contractor, and overview of the project data. Collected project data and interview data are analyzed using the developed framework. Results of the data analysis are verified through follow-up interviews with the main contractor firm. Findings of the study suggest that it is possible to evaluate the BIM performance through analysis of collected BIM big data using the proposed systematical approach. Several performance problems were identified during the data analysis. Follow-up interviews revealed that identified performance problems from the data analysis largely coincided with the real-life experiences and accurate data entry is the key criterion for the analysis to yield correct results. The proposed framework should be tested in wider range of studies and may serve as a foundation for a future benchmarking system. Future work should focus on refining performance metrics, establishing a BIM big data database for benchmarking, exploring data's potential to be used for real-time performance assessment, and implementation of emerging Artificial Intelligence (AI) techniques for the analysis of big data.

    Bim Execution Process of Construction Companies for Building Projects
    (İzmir Institute of Technology, 2016) Gerçek, Bilge; İlal, Mustafa Emre; Günaydın, Hüsnü Murat; Tokdemir, Onur Behzat
    Building Information Modeling (BIM) is an emerging concept in architecture, engineering and construction (AEC) industry promising to replace traditional 2D based construction documentation and management procedures and to reduce rework and cost in project execution. The level of information that could be assigned to building objects in BIM technologies could provide vast amounts of benefits to construction projects throughout projects’ life-cycle. Implementation of BIM, however, requires strategic planning to enable achieving these potential benefits. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementation is a statutory obligation. In contrast, BIM implementation and/or deliverables has not been mandated by government or organizations yet in Turkey, therefore organizations which plan to adopt BIM processes have to develop their own implementation plans. The purpose of this study is to provide guidance in BIM implementation for construction companies particularly during the construction phase of the building projects. BIM standards and guidelines, and studies related to BIM implementation have been reviewed and important aspects of implementation have been identified. A case study of BIM implementation at a large construction company in Turkey to conduct quantity takeoff and cost estimation are presented and unique challenges of BIM implementation in Turkish AEC industry are discussed.
