N2 - Extracting two-dimensional (2D) views and drawings from a three-dimensional model is essential for building information modeling (BIM). However, in practice, generating 2D deliverables from BIM results in additional work (>41%) and reduced consistency between drawings and BIM model data. This study aims to determine the information essential for acceptable drawing outcomes. Based on the drawing requirements at the construction documentation stage, information requirements for the BIM dataset were determined using the Delphi method. Moreover, a BIM data requirement framework for 2D deliverables was developed, and its effectiveness was verified via application to a pilot project. Consequently, the additional work reduced from 41% to 7.1%, and approximately 92.9% BIM-data consistency was secured. The data requirements for drawing creation in the current standards are insufficiently defined. This study can increase the productivity of the BIM-based drawing creation and determine additional information required in the existing standards to maximize the value of BIM.
