Introduction Construction is unlike any other sector in that a contractor must pledge a price to the client before knowing the final expenses.
AUTODESK QUANTITY TAKEOFF 2021 SOFTWARE
The most significant method was revealed to be equipped estimators with the required software information to prepare more accurate cost estimates using BIM-based quantity takeoff.ฤก. Later on, twelve possible measures to improve estimating accuracy through BIM-based takeoff were tested in the questionnaire survey. Then the study concludes factors that facilitate increasing the price accuracy with the use of BIM. This paper presents a comprehensive literature review to get an overview of the cost estimation and BIM-based and CAD-based quantity takeoff while identifying the factors affecting accuracy with their advantages and drawbacks. To attain the aim, an extensive literature synthesis was piloted to develop a questionnaire survey was carried out upon the key findings of the literature. Thus, this study intends to ascertain to which extent the BIM base quantity takeoff is being satisfied with the accuracy of cost estimation by evaluating the impact of BIM-based takeoff advantages and drawbacks for the accuracy of cos estimation and recommending suitable measures to improve the accuracy. Meanwhile, there may be few hindrances that lead to errors in price accuracy of BIM-based quantity takeoff. Because of its direct quantity extraction features, using BIM in quantity takeoff leads to highly accurate quantities and cost estimation. Building Information Modeling (BIM) is a distinguishing result of the growth of modern information technology in the building industry. To achieve a proper estimate, price accuracy is fundamental. In every construction project, cost estimation is one of the most crucial aspects that is critical to the project's success.
