As the global construction industry grows in scale, complexity, and speed, Building Information Modeling (BIM) technology is maturing and gaining traction. However, BIM is currently applied mainly during the early design and construction phases. After project completion and handover, the extensive investment in BIM by owners often goes underutilized. This article explores how BIM is increasingly being leveraged for building operation and maintenance, using SOHO projects as a case study.
Today, SOHO projects are progressively integrating more systems into their BIM operation and maintenance platforms, significantly enhancing property management capabilities. This marks a crucial step forward for BIM in operational contexts and serves as a pioneering example for the broader market. While the current use of BIM in SOHO projects barely scratches the surface, ongoing efforts aim to incorporate even more systems and functionalities. Looking ahead, BIM’s scope will expand beyond property management to include commercial management, ultimately becoming a comprehensive platform that integrates all building information and applications throughout construction and operation phases. This evolution is poised to become a major trend in the construction industry.
By integrating energy management systems with BIM technology, SOHO projects offer higher-value, comprehensive property management solutions. This BIM-driven approach combines spatial information with real-time data, allowing property managers to intuitively visualize building details, monitor energy usage, and assess other related conditions on a 3D platform. This transformation evolves from a simple 3D energy efficiency management tool into a fully-fledged BIM operation and maintenance platform, revolutionizing the lifecycle management of public buildings.
BIM-Based Property Management System
This initiative represents a comprehensive integration of BIM, cloud computing, and the Internet of Things. It covers a wide range of property management systems, including information overview, hydraulic balancing, mechanical ventilation, sensing, lighting, elevators, temperature distribution, and video surveillance. These systems collectively support detailed building information management throughout the operation and maintenance stages.
Mechanical Ventilation
By integrating with BIM, the mechanical ventilation system visualizes the status of equipment, pipelines, and valves in a clear, 3D format. The system allows for classification and layering based on application characteristics, enabling focused analysis on specific floors, areas, or devices using comprehensive spatial data.
Property managers can monitor system air and water flow balances, as well as the opening status of each air outlet, through the BIM interface. When combined with ambient temperature data, air and water volumes can be adjusted in real time to optimize comfort and efficiency. During maintenance, the BIM system provides clear pipeline status, simplifying the process and reducing confusion over complex layouts.
Vertical Transportation
The 3D elevator model accurately represents the spatial positions and attributes of real elevators, including entrance and central elevators, as well as the floors they serve. Attributes such as elevator type (straight elevator or escalator), model, size, and capacity are clearly depicted. Straight elevators and escalators are represented by distinct 3D solid shapes for easy identification.
The BIM platform visualizes elevator usage and energy consumption, providing property management with clear insights. By analyzing human movement patterns and pedestrian flow, managers can optimize elevator system strategies to improve efficiency and user experience.
Temperature Monitoring
The BIM platform collects data from temperature sensors throughout the building. It also integrates measurements for humidity, carbon dioxide levels, light intensity, and air cleanliness, providing a comprehensive environmental overview.
Temperature distribution is visually displayed using colored indicators for each sensor point in public areas. Users can filter sensors by temperature range, identify outliers, and view historical temperature trends. This allows property managers to monitor indoor environmental conditions at a glance and make informed adjustments to HVAC systems, enhancing comfort and energy efficiency.
Water Balance
By interfacing with water meters, the BIM platform clearly maps the building’s water network and assesses water balance. It analyzes pipeline data to quickly detect leaks, enabling timely repairs and reducing waste. Additionally, property managers can easily locate pipelines during renovations, avoiding issues with concealed works.
Tenant Information
The BIM platform manages tenant information alongside their energy usage and costs, with applications extending to business management. When integrated with mobile devices, tenant activity, promotions, locations, and reviews can be directly communicated to end customers. This functionality enhances tenant engagement and generates greater value for businesses.
Basement Equipment
The BIM platform displays detailed information and operational status of basement equipment, enabling quick location of devices (see Figure 7). Typically, equipment and power rooms are situated in basements. Through BIM, managers can oversee operation status, equipment details, spare parts, and maintenance records. When combined with intelligent parking systems, it can also show parking availability, help customers find spaces and vehicles, and assist property staff in garage management.
Video Surveillance
Integration with video surveillance allows the BIM platform to display camera locations clearly. Clicking a camera icon reveals live video feeds, and multiple streams can be viewed simultaneously or switched continuously, similar to traditional security systems. Compared to conventional setups, this approach offers clearer location data and enhanced video retrieval, greatly improving system functionality.
Data Analysis
The data analysis interface breaks down Galaxy SOHO’s energy consumption into a hierarchical model, analyzing energy use and costs across different time frames and categories. It supports comparative analysis between subcategories, allowing managers to extract meaningful insights from the rhythmic visual data.
The capabilities of the BIM operation and maintenance platform extend far beyond these examples. Serving as a top-level building platform, it connects diverse systems and spans multiple domains including property and commercial management. Leveraging BIM’s high visualization, even small technological innovations can greatly enhance user experience. Imagine customers no longer needing to worry about parking, children’s safety in malls, or choosing stores—instead, they can enjoy seamless experiences provided by merchants, driving greater attention and value for businesses.
BIM is a highly visual integrated platform that, when combined with traditional systems, significantly elevates their capabilities. By incorporating positioning and information systems, it creates richer user experiences. In the future, this technology will expand to more public facilities such as commercial centers, offices, airports, and museums. As BIM adoption broadens, its operation and maintenance applications will undoubtedly offer improved management solutions and experiences for building operators worldwide.
