In this issue, BIM draws inspiration from Taiwan. Let’s explore the challenges faced by BIM in Taiwan. In previous articles, the author has consistently focused on Taiwan’s BIM developments. Today, instead of comparing applications to those in mainland China, we aim to learn from Taiwan’s shortcomings. Understanding and avoiding these pitfalls is a valuable approach to successful BIM adoption.
1. Lack of effective vertical communication, coordination, and integration among engineering disciplines: Professionals upstream and downstream often focus solely on their individual phases and responsibilities, neglecting the overall project goals.
2. Poor communication and coordination among parallel engineering teams: During design or construction, each team handles their own 2D drawings independently, which makes integrating design content before construction challenging. This frequently leads to design flaws. On site, contractors and subcontractors prioritize convenience and speed, resolving issues as they arise, which results in wasted resources, rework—such as crossing beams and walls—and dismantling. These inefficiencies increase costs, delay schedules, and cause disputes.
3. Inadequate management of engineering data: Without a centralized integration platform, professionals must individually correct drawings, leading to inconsistent versions, discrepancies between drawings and actual construction, opaque data, difficulty reusing drawings, and mismatches between completed drawings and current site conditions.
4. Engineering units often compromise the rights and interests of owners: Since construction projects involve multiple specialized partners, there is often information asymmetry between owners and professionals regarding design and construction details. Parties with more information may exploit this advantage, resulting in adverse effects such as over-design, cutting corners, and falsifying data, ultimately harming owners’ interests in cost, quality, schedule, and safety.
5. Fragmented and easily overlooked information: In Taiwan’s engineering practice, data generated at each project stage is often poorly stored. Even when data is stored, it tends to be scattered rather than centralized in a database. When databases exist, they are rarely integrated or actively used, making it difficult to control costs for updates or facility maintenance during operation.
6. Design errors cause significant cost overruns and project delays: Research on international construction projects shows that 80% to 90% of project failures or deviations from owner requirements stem from design errors. The cost of dismantling and rebuilding due to these errors typically accounts for about 14% of the project contract value. Such errors include design changes, omissions, defects, quality issues, and non-compliance with specifications.
7. Limited adoption of information and communication technology (ICT) reduces construction productivity: Two main factors hinder ICT use in construction: the industry’s structure and production behaviors, and the complexity of integrating and communicating specialized knowledge. Construction processes, especially during the building phase, often involve design changes requested by both owners and contractors. Owners may change designs due to evolving ideas, incomplete initial planning, or discovering that the design does not meet requirements once construction begins. Current communication methods—mainly 2D floor plans—are inadequate, highlighting the need for better communication tools.
In conclusion, this issue of learning from Taiwan’s BIM experience reveals several critical challenges. It is important to note that Taiwan adopted BIM years before mainland China and has established its own BIM standards. Therefore, it is essential to study these lessons carefully and avoid superficial or exaggerated BIM implementations, which could hinder BIM’s development in mainland China.
