    Assessment of building information modeling impact on small scale construction projects
    (İstanbul Gedik Üniversitesi, 2021) Abdulghani, Ghaith Rabeea; Güllü, Ahmet
    While time passes and life changes, the development of technology is taking place in every part of our life quickly, also it affects daily life. it creates new tools, procedures, and methods for all sectors, and simplifies many operations. Nowadays, design tools that depend on computers have been used in the construction industry, it has a direct effect on the whole project life, and it has made a revolution in the construction sector. Building information modeling (BIM) simply refers to the development of a building model generated by using the computer, that model is rich of data, object-oriented, smart and also a parametric digital representation of the building. This research discusses the assessment of BIM impact for the small scale construction industry, it mainly focuses on quantity takeoff and accuracy of projects, firstly it presents the definition and the main concept of BIM. Then, a case study of a 3-storey building project in Baghdad is done to evaluate the effect of BIM quantity takeoff, tendering, and other effects on the project, Autodesk Revit 2020 software has been used to create the model of the building. The results showed that BIM can provide easy, detailed and sufficient drawings and the quantities and prices were extracted and compared with the quantities and prices that have been calculated with traditional ways, Revit calculation have reduced the total estimated cost by 4% compared to the total tender estimated cost, 6% for finishing estimated cost, and nearly no change in structure price.
