As widely recognized, BIM (Building Information Modeling) applications in China are primarily utilized during the design and construction phases. However, BIM’s potential extends far beyond these stages. Today, I will share with you the specific applications of BIM across different stages of the construction lifecycle.
(1) Feasibility Assessment Stage
Compared to other lifecycle stages, BIM applications at the feasibility assessment stage are less commonly introduced in literature. Despite limited references, the key BIM applications during this phase include:
- Scheme comparison and decision-making
- Preliminary cost estimation
- Modeling of the existing site conditions (local environment simulation)
(2) Planning Phase
Beyond conventional literature classifications, when planning stages overlap with design or remain undefined (e.g., planning and design timing), it is essential to classify BIM applications based on technical service project content. Practical feasibility should be confirmed via surveys. Preliminary BIM applications during the planning phase include:
- Modeling of existing site conditions (local environment simulation)
- Preliminary cost estimation
- Spatial planning
- Site analysis
- Design result review
- Duration planning and stage analysis
- Design scheme comparison and decision-making, including conceptual design review and display
- Structural and MEP (Mechanical, Electrical, Plumbing) design schemes
- Design evaluation and conceptual design finalization
- Building performance simulation and analysis
- Visual simulation (both 3D and cocoa visualization)
- Quantitative modeling
- Space design and design drawing review
- Land use and transportation planning with traffic impact simulation
(3) Basic Design Phase
While common literature does not always separate basic and detailed design, this study divides the design phase into two stages to better address practical applications. Classification is based on technical service project content, with feasibility verified by questionnaires. BIM applications during the basic design phase include:
- Basic design tasks such as architectural, structural, MEP pipeline design, engineering design, 3D modeling, geometric modeling, and civil engineering on-site design
- Visual analysis and simulation, including virtual walkthroughs and 3D visualization presentations
- Communication, coordination, and verification through 3D models
- 4D schedule planning
- Detection of spatial conflicts and collisions among architecture, structure, MEP pipelines, and interior decoration
- Initial design cost estimation (basic design estimation and area breakdown statistics)
- Engineering analysis and simulation, including structural, energy, green energy evaluation, mechanical, load force, stress, geometric, live load, structural system and parameter, energy dissipation, static and dynamic load, and lighting analyses
- Basic design finalization
- Sustainable development assessment (EEWH)
- Design drawing review and verification
- Application for and acquisition of construction permits
(4) Detailed Design Phase
BIM applications during detailed design should also be classified according to technical service content and validated through surveys. Key BIM uses in this phase include:
- Detailed design covering architectural, structural, MEP pipeline design, 3D modeling, geometric modeling, on-site civil engineering design, and professional model construction
- Visual analysis and simulation (virtual walkthroughs, 3D visualization)
- 3D model-based communication, coordination, and verification
- 4D schedule planning
- Collision detection and conflict analysis in architectural, structural, MEP, and interior decoration models
- Cost estimation and bill of materials preparation, including detailed cost assessment and quantity extraction
- Engineering analyses similar to those in basic design
- Design drawing output
- 3D collaborative task integration for detailed design
- Development of contracting budgets and preparation of contract documents
- Detailed design finalization and design checks
- Quality control and quality assurance
(5) Construction Phase
During construction, BIM applications are categorized similarly but validated through practical surveys. Preliminary BIM applications in this phase include:
- Constructability reviews (pre-construction assessments)
- 4D project scheduling and virtual work planning
- Collision and interference detection across architecture, structure, MEP pipelines, and interior decoration
- Construction simulation including 3D control, 4D progress simulation, and virtual vs. actual progress comparisons
- Material estimation, including cost reports, 5D cost analysis, and quantifiable project material details
- 3D visualization presentations for construction progress and reporting
- Communication, coordination, and verification via 3D models
- Engineering analysis simulations
- Equipment performance verification and acceptance
- Construction modeling and detailed drawing outputs
- On-site design changes management
- Obtaining usage licenses
- Project completion and finalization
- Completion modeling and history management
- Facility management modeling and integrated model assembly
- On-site utilization planning, including work area safety and construction safety analyses
- Construction system design
- Data-driven manufacturing such as prefabrication and component processing
- Quantity surveying
- Equipment and material management
- Quality and safety management
- Geospatial problem tracking for on-site progress monitoring
- Product inspection and material testing
(6) Operation and Maintenance Phase
In this final phase, the feasibility of BIM applications has been confirmed through surveys and literature. Key BIM uses include:
- Asset management, including facility asset tracking and GIS-based toll and road management
- Space management, tracking usage and facility space
- Energy monitoring
- User services
- Cleaning and preservation management
- Facility and building maintenance budgeting
- Establishing facility history models
- Maintenance planning covering equipment management, repair information, water mitigation, and operational management
- Facility and building system analysis
- Disaster response planning for emergencies and repairs
- Operational system establishment
- Transportation management systems
That concludes our overview of the specific BIM applications across various construction phases. I hope this article proves helpful to everyone!
