| Abstract |
In the realm of domestic design, the use of 2D CAD for creating design information has long been a major contributor to subpar design
quality. The advent of Building Information Modeling (BIM) has prompted numerous efforts to enhance the process of delivering design
information. Yet, many of these studies have overlooked the critical shift to a 3D BIM-based design process and production method. One of
the most significant challenges in the design stage has been ensuring the integrity of design drawings. This study seeks to address this
challenge by exploring a 3D BIM model-based documentation approach. To do so, an analysis of construction documents derived from 3D
BIM models was conducted, breaking them down into sheets and views. For this analysis, a dataset comprising 298 sheets in the architectural
field and 143 sheets in the structural field were collected as research data. Initially, these construction documents were categorized into two
groups: those generated based on 3D BIM and those based on 2D CAD. Then the types of views extracted from the 3D BIM model across
each sheet were meticulously examined and cataloged. These findings revealed that in architectural construction documents, a total of 481
views were employed across 214 sheets created from 3D BIM models. Similarly, in structural construction documents, a total of 252 views
were employed across 107 sheets created from 3D BIM models. Importantly, these views contain design information that automatically adjusts
as the 3D BIM model evolves. The outcomes of this study hold potential not only for enhancing the consistency of design information but
also as foundational data for further research into BIM data composition, templates, and library development for documentation, considering
the specific characteristics of different facilities. |
