The concept of BIM forward design is conveyed through 3D models, serving as the foundation for collaborative design across multiple disciplines. Ultimately, optimized 3D models lead to the generation of 2D drawings.
In traditional 2D design drawings, individual disciplines often fail to detect issues during their own reviews. However, when these drawings are combined and submitted to on-site construction teams, numerous gaps frequently emerge. Additionally, since different designers create these drawings, variations in drawing styles can cause difficulties in interpretation, hinder effective communication between professions, and prevent the level of collaboration efficiency required.
Traditional design is largely result-oriented, focusing on presenting final design outcomes. In contrast, BIM forward design is process-oriented, with drawings reflecting the evolving design process through the model. Because BIM involves more stages during the early design phase, its initial speed can be slower than that of traditional 2D design. For businesses to realize efficiency gains from BIM forward design, it is unrealistic to rely solely on the productivity of individual disciplines. Instead, greater efficiency must come from multidisciplinary collaboration, enabling faster and better results than traditional design methods throughout the entire design lifecycle.
Talent development is equally critical for BIM advancement. Currently, many design firms actively research BIM forward design, but there is a shortage of dedicated BIM professionals with strong architectural design experience. Most BIM technicians have traditionally focused on repetitive tasks like model rework, lacking deep design expertise. As a result, traditional designers still complete much of the core project work. BIM-related projects typically require close cooperation between BIM engineers and traditional designers, which can slow progress, reduce efficiency, and sometimes cause conflicts due to collaboration challenges. The scarcity of professionals skilled in both design and BIM technology makes it difficult for even leading design firms to fully advance BIM forward design research.
