There are many summaries of the benefits of BIM available online, along with insights from numerous experts. Here, I aim to consolidate these perspectives to help you better understand BIM’s advantages. Due to space constraints, this article covers the first part of the summary. Through this series, I hope you gain a deeper appreciation for the benefits of BIM and its key features.
1. Model Creation
The benefits BIM offers fundamentally rely on having a BIM model based on the BIM concept. To meet market demands, we assist clients in building high-quality BIM models that can be continuously utilized in the future. These models are created from design concepts and associated graphical and textual data generated at each project stage. Collaborative information is integrated into a BIM (Building Information Modeling) model according to the required Level of Development (LOD) at each phase. The models can be categorized by their application as follows:
1. Architectural Model: Includes exterior walls, interior walls, ceilings, ducts, doors, windows, exterior decorations, and more.
2. Structural Model: Covers columns, beams, floors, and other structural components.
3. MEP Model: Encompasses plumbing, air conditioning, fire protection, smoke exhaust, and other mechanical, electrical, and plumbing pipeline systems.
4. Facility & Equipment Model: Represents building equipment such as air conditioning units, firefighting devices, and specialized machinery.
2. Supporting On-Site Construction
When the BIM model extends from design to construction, it not only links the original graphics and data but also monitors various conditions on-site. This allows comparison between actual and planned progress, helping to minimize delays. Key aspects include:
1. RFID Material Control: Using RFID tags and readers to track incoming materials and construction items.
2. Real-Time Construction Progress Monitoring: Deploying cameras from multiple angles to monitor construction progress 24/7, with data sent back for comparison and analysis.
3. Progress Reporting Process: Establishing a workflow for reporting site conditions, RFID data feedback, and progress control improves investors’ and supervisors’ understanding of construction status and cost analysis.
4. Progress Delay Warning Reports: Comparing actual progress to planned schedules helps identify delays in tasks and durations, facilitating timely review and follow-up.
5. Mobile Management: Mobile devices display construction models in real time, aiding construction workers’ understanding and enabling supervisors to monitor quality. They also allow real-time recording of site conditions for data analysis and reporting.
3. Pre-Construction Simulation
Careful planning is essential during construction to ensure the rationality of every element, from scheduling to task sequencing and workflow. Traditionally, experienced senior engineers rely on their expertise to create optimal work schedules. However, introducing BIM models at this stage, combined with practical planning knowledge and construction methodologies, allows for a visual review of the schedule’s logical correctness and the construction flow’s efficiency. This approach enables simulation of construction sequences and material deliveries, leading to more accurate and efficient project execution.
That concludes this issue’s summary of BIM’s benefits. I will continue to share further insights regularly, highlighting the transformative impact BIM technology has had on the construction industry and society as a whole.
