Abstract: In order to explore the development path of high-quality implementation of BIM forward design, an analysis was conducted on the characteristics and current status of BIM forward design, as well as the factors constraining its high-quality implementation.Comparative tests were performed on four 2D/3D collaborative platforms.The results indicate that key factors for ensuring the high-quality implementation of BIM forward design include establishing an enterprise BIM talent pool, upgrading computer configurations, researching methods for BIM forward design, and creating an environment conducive to the high-quality implementation of BIM forward design.A collaborative 2D/3D design process suitable for the current stage was proposed, and the test results and applicable environment of the four 2D/3D collaborative platforms were summarized.
