Evaluation of BIM Benefits
Yesterday, after discussing the benefits of reducing drawing errors, we will now focus on the advantages gained by minimizing information requests.
Construction projects are inherently multidisciplinary and complex. Due to limitations in traditional diagram representations, many on-site issues require input from specialists—commonly referred to as Requests for Information (RFIs). Often, key professionals or decision-makers are off-site, and various issues must be communicated through different channels to the relevant experts. While some problems can be resolved in real time, more complex issues involving multiple disciplines often require consensus through numerous meetings. This process consumes considerable time and manpower.
By using BIM technology, the need for such information requests can be significantly reduced, leading to improved work efficiency and tangible benefits.
Evaluating the actual benefits of BIM can be challenging due to the uniqueness of each construction project—varying personnel, equipment, and site conditions make comparisons difficult. However, one example comes from the newly constructed Second Research Center at the University of Colorado Denver Health Science Center. Because it closely resembles the previously built First Research Center, it was possible to compare BIM usage with the traditional process. The results showed a 37% reduction in information requests when using BIM.

That concludes today’s discussion on the benefits of reducing information demand in BIM evaluations. Due to limited data availability in many cases in China, we have not provided a more detailed analysis here. Thank you for your understanding.
