Detection of Architectural Drawings Errors in 3 Dimension

Abstract

In construction projects architectural drawings are the main documents which show how a structure has to be built. In this sense, most of the data necessary for project management are prepared based on these drawings. Therefore, architectural drawing errors will adversely affect the constructability and hence, the time and cost of a construction project. On the other hand, although the structures are built 3D, architectural drawings are prepared 2D. This circumstance complicates the detection of drawing errors during the design phase. In other words, drawing errors are mostly encountered during the construction phase. In fact, drawing errors are risks which can be detected during the planning phase in nature. In this study, it was argued that to detect drawing errors in planning phase architectural and engineering drawings should be prepared 3D instead of 2D. In this context, drawings of an official approved hotel project were redrawn by means of BIM to determine whether there exists drawing errors. The results of the study revealed that drawings involved many errors and 3D drawings enable early detection of them.
