As BIM applications continue to evolve, projects that simply use BIM alone are becoming rare. Instead, BIM is increasingly integrated with other advanced technologies and application systems to unlock greater comprehensive value. Examples include BIM+PM, BIM+cloud computing, BIM+IoT, and more. What exactly is “BIM+”? How does it work? A review of the 2015 China Construction Industry Informatization Development Report explores the theory and practice behind BIM and nine major integrated technology applications.
BIM + Project Management (PM)
Project Management (PM) involves the comprehensive oversight of a project’s timeline, quality, and cost objectives to meet predetermined goals. The integration of BIM and PM is achieved by creating a data exchange interface between BIM software and project management systems. This approach leverages BIM’s intuitiveness, analytical capabilities, shareability, and manageability to provide accurate and timely data and technical analysis for various project management operations. Combined with project management processes and statistical analysis, this integration forms a complete management loop—including data generation, utilization, approval processes, dynamic statistics, and decision-making analysis—to enhance overall project management capabilities and efficiency.
By integrating BIM with PM, project managers gain visual management tools. For instance, 4D management applications visually represent construction progress and the entire building process, aiding in rational construction planning and resource optimization. Additionally, BIM integrated with PM enables more effective analytics. For example, comparing revenue, planned costs from BIM integrated models, and actual costs from PM systems supports dynamic cost control. This integration also provides data support for cost estimation, material management, and subcontractor quantity reviews, significantly improving work efficiency and decision-making quality.
BIM + Cloud Computing
Cloud computing delivers internet-based software, hardware, and information resources on demand to computers and other devices. Integrating BIM with cloud computing transforms BIM applications into cloud services—a developing approach in China.
Cloud computing’s powerful processing capabilities offload complex, computationally intensive BIM tasks to the cloud, enhancing efficiency. Its vast data storage allows synchronization of BIM models and related business data, enabling users to access and share information anytime and anywhere. This connectivity extends BIM beyond the office, allowing construction site personnel to retrieve BIM data and services via mobile devices in real time.
BIM + Internet of Things (IoT)
The Internet of Things (IoT) connects objects to the internet through devices like RFID, infrared sensors, GPS, and laser scanners, facilitating intelligent identification, positioning, tracking, monitoring, and management.
Combining BIM and IoT integrates information across the entire building lifecycle. BIM manages high-level information integration, interaction, visualization, and management, while IoT handles data sensing, collection, transmission, and monitoring. Together, they enable a closed-loop information flow throughout construction, blending virtual information management with the physical environment. Currently, BIM is widely applied in design and is expanding into construction and operation phases, while IoT focuses mainly on construction and operation. Their integration promises significant added value.
BIM + Digital Processing
Digitization converts various types of information into measurable numerical data stored in models, which computers then process. Digital processing uses manufacturing equipment guided by these digital models.
Integrating BIM with digital processing means converting BIM data into digital models suitable for automated manufacturing. This integration is primarily applied to precast concrete slab production, pipeline prefabrication, and steel structure fabrication. Automated precision machinery ensures components are produced with minimal error and higher efficiency. Prefabricated parts like doors, windows, bathrooms, concrete elements, and steel structures can be manufactured off-site and assembled on-site, shortening construction time and improving quality control.
BIM + Intelligent Total Station
Construction surveying plays a crucial role in engineering, including establishing control networks, building layout, deformation monitoring, and final surveys. With the rise of super-large and tall buildings with complex designs, total stations—electronic theodolites—are widely used for surveying and layout. These devices are evolving toward automation and intelligence.
An intelligent total station is motor-driven and can autonomously identify, aim, and measure multiple targets without human intervention, even measuring distances to general objects without reflective prisms.
Integrating BIM with intelligent total stations involves using BIM models onsite to drive measurements based on 3D spatial coordinates. This enables comparison of real construction data with BIM models to check deviations and inform detailed designs of specialties like MEP, interior decoration, and curtain walls. The intelligent total station ensures precise layout and positioning on-site using construction axes and control points, providing accurate guidance for construction teams. Additionally, it supports quality control by measuring completed structures and comparing actual data to design specifications.
BIM + Geographic Information System (GIS)
GIS is a computer system that manages geographic spatial data, enabling storage, analysis, and visualization of earth surface-related data in an intuitive map format. BIM and GIS integration happens through data, system, or application integration. GIS can be embedded in BIM platforms, BIM within GIS, or both deeply integrated to leverage their strengths and extend applications.
Currently, BIM-GIS integration is applied in urban planning, traffic analysis, microenvironment studies, pipeline management, residential planning, disaster prevention, and building renovation. Compared to standalone applications, this integration significantly improves modeling quality, analytical accuracy, decision-making speed, and cost management.
BIM + 3D Scanning
3D scanning combines optics, mechanics, electronics, and computing to capture the spatial shape, structure, and color of objects, producing high-accuracy surface coordinate data. 3D laser scanning, or reality capture technology, uses fast laser measurements to obtain detailed 3D data quickly, enabling rapid creation of accurate 3D models.
This technology effectively records complex construction sites and, by comparing scanned data with design models, provides valuable insight for inspections and quality control. For historic buildings, it creates precise digital archives that facilitate maintenance and restoration. In complex or hard-to-modify situations, 3D scanning supplies real on-site data to customize components and materials.
The integration of BIM and 3D scanning involves coordinating and comparing BIM models with scanned data to improve quality inspection, accelerate modeling, and reduce rework. For example, the Shanghai Center Building project uses large-scale 3D laser scanning to reconstruct detailed 3D models of complex environments and compare them to original designs, supporting accurate decoration and specialty design. This integration boosts construction inspection efficiency and accuracy and underpins advanced design efforts.
BIM + Virtual Reality (VR)
Virtual Reality (VR) creates immersive 3D sensory environments using advanced computer, sensing, simulation, and microelectronics technologies, providing realistic visual, auditory, tactile, and force feedback experiences. VR represents a significant leap beyond traditional computer interfaces.
BIM’s goal is to build an information database covering the entire project lifecycle for model-based data integration and sharing across stages and disciplines. Integrating BIM with VR includes virtual scene construction, construction progress simulation, complex local plan simulation, cost simulation, multidimensional joint simulations, and interactive walkthroughs. This enhances VR applications throughout construction project lifecycles.
Combining BIM with VR improves simulation realism beyond traditional 2D or 3D methods by creating immersive virtual buildings. All relevant information can be integrated into virtual scenes for real-time, multi-perspective analysis that guides design, construction, supervision, and monitoring.
This integration also boosts interactivity. Users can switch between construction plans in real time, experience different processes from the same viewpoint, and compare alternatives to choose the best approach. Specific elements can be modified and analyzed live. The full construction process can be observed virtually to identify issues early, avoiding costly rework. VR in construction is an inevitable trend with promising prospects to transform design and build processes.
BIM + 3D Printing
3D printing is an additive manufacturing technology that builds objects layer by layer from digital 3D models, combining digital modeling, electromechanical control, IT, materials science, and chemistry.
Integrating BIM with 3D printing primarily involves three approaches: miniaturizing BIM models for design review and simulation; printing BIM models as solid components or entire buildings during construction to partially replace traditional methods; and producing physical models for construction plan presentations. This fusion of technologies opens new pathways from design concepts to physical objects and offers efficient solutions for manufacturing complex components.
For example, overall building 3D printing uses BIM designs fed into specialized printers to construct entire structures. This method reduces labor costs and avoids dust and waste, making it an environmentally friendly process with clear advantages in energy saving and sustainability over traditional methods.
As technologies advance, current challenges in integrating BIM and 3D printing will be resolved, and costs for printers and materials will become more affordable. This will broaden 3D printing’s applications and increase construction automation. While 3D printing may not yet surpass industrial prefabrication in efficiency or cost for mass housing production, it excels in personalized and small-scale projects. With growing demand for custom buildings, 3D printed constructions have vast market potential.
