When BIM was first introduced in China, it was primarily used on a trial basis during the design phase. Over time, however, the industry and enterprises have deepened their understanding of BIM, expanding its application from design into the construction phase. Many companies have since gained valuable experience applying BIM technology during construction. Today, I will discuss the value BIM brings specifically to the construction phase.
1. BIM integrates data from various stages and processes throughout construction, creating a platform for seamless information exchange and sharing. This breaks down the barriers of the traditional step-by-step information handover, shortens transmission time, and reduces interference. By establishing a BIM-based 4D construction progress management model, construction activities can be monitored and queried in real time, which significantly enhances construction management efficiency.
2. Since the data and attributes of building components within BIM models are derived directly from the implementation environment, the models reflect actual conditions. Based on this, collision detection and construction simulation can be performed to optimize designs for components, pipelines, buildings, and structures during construction. This allows for effective planning of machinery and material placement, early identification of potential issues, and timely adjustments of any unreasonable construction areas. By discussing the best construction plans and solutions beforehand, BIM helps minimize errors, omissions, and clashes common in traditional 2D models, ultimately improving construction quality and shortening project timelines.
3. In addition to construction simulation, virtual demonstrations and dynamic simulations are conducted to address key challenges and difficult construction points. Multiple construction plans and process options are presented for critical sections, enabling the selection of the most effective approach. BIM technology can also be used to create manuals detailing spatial positioning, construction processes, methods, and hazardous areas for workers during operations. This enhances safety by reducing risks and ensuring the well-being of construction personnel.
4. By utilizing a BIM 4D model, precise control over construction progress is achievable. It allows for effective management of resource allocation, site layout, material quotas, and other aspects across each phase of construction. Ensuring adequate supply of resources, maintaining a safe working environment, and proper material handling reduces waste and unnecessary costs. Additionally, project managers gain stronger oversight of progress, resources, and expenses.
5. Introducing BIM technology also facilitates the creation of a collaborative platform that unifies the efforts of various disciplines and teams. This strengthens team cohesion, improves communication, and enhances overall collaboration. Moreover, dynamic management and real-time monitoring of component prefabrication and processing become possible, shortening production time, assuring component quality, and accelerating the overall construction schedule.
6. The BIM model developed during construction can be directly handed over to third-party operation and maintenance teams upon project completion. This enables seamless data exchange throughout the entire project lifecycle—from design and construction to operation and maintenance. For future facility management, the operation team can utilize the BIM data created during construction as a valuable resource or database for property management and related applications.
In summary, what is the value of BIM technology during the construction phase? That concludes my discussion. In practice, BIM has also been applied in China for precise budget control and personnel allocation during construction, which I have not covered here. Those interested are welcome to contribute further insights.
