Analysis of Designs - A comparative Study of BIM and AutoCAD

Abstract

Building information modeling (BIM) is software for the efficient designing of the structures, which provides the advanced level designing of the structures along with the quantity takeoff required for the construction of the respective structure. On the other hand, AutoCAD is the traditional drafting software which is not enough efficient as compared to the building information modeling software. This research also focuses on the visual as well as featural differences of the building information modeling software (BIM) and AutoCAD, by the qualitative design analysis of the same structure from both AutoCAD and BIM, and also by quantitative analysis technique for this research which incorporates the questionnaire online survey, to collect the responses from various experts such as civil engineers of different years of experience and BIM experts of the different levels and years of experience. According to the design analysis result, by using BIM and AutoCAD Models and drawings, to visualize the difference between the features and level of advancement and efficient modeling. The BIM allows us to design structures that are more attractive as well as well-structured along with the quantity takeoff for the specific drawing. While AutoCAD is just the drawing software, it does not support the quantity takeoffs and finished look better than that of BIM, according to the quantitative results, it can be concluded that implementing BIM could reduce human error and also provides user-friendly ease to work, and also to perform necessary variations without reworking on the model from the beginning.
