Continuing from the previous discussion, let’s further explore the secondary applications of BIM in prefabricated buildings.
Design Phase Application Objectives
Model: Develop engineering survey models along with architectural, structural, and MEP (mechanical, electrical, plumbing) design models.
Application: Utilize 3D visualization, conduct performance analysis, compile statistics on main building materials and components, detect design conflicts, and generate 2D construction drawings.
Management: Implement BIM-assisted design management processes.
Application Requirements:
Model: Achieve model detail level LOD300.
Application: Perform comprehensive site analysis, optimize design schemes, enable collaborative design, conduct clash detection, analyze performance, estimate investments, and produce 2D mappings.
Management: Ensure completed models and applications are reviewed and approved by responsible professionals, establishing a BIM-assisted design management workflow.
Production Phase Application Objectives
Model: Receive and review architectural design models, then create detailed PC (precast concrete) component design models based on detailed drawings.
Application: Effectively use design models for PC component drawings and quantity calculations.
Management: Apply BIM to support the management of PC component production.
Application Requirements:
Model: Maintain model detail level LOD300.
Application: Complete detailed component design and integrate production information.
Management: Models and applications must be signed off and confirmed by responsible professionals.
Construction Phase Application Objectives
Model: Develop detailed design models for architecture, structure, and MEP; create construction models for critical construction nodes and site layout.
Application: Conduct construction simulations and walkthroughs, perform floor inspections, detect construction conflicts, and compile quantity statistics.
Management: Establish a comprehensive BIM management system.
Application Requirements:
Model: Achieve model detail level LOD400.
Application: Optimize construction plans, simulate construction progress, coordinate on-site layout, manage equipment and materials, oversee quality and safety, and facilitate final acceptance processes.
Management: Implement BIM roles division and establish a signature approval system.
Operation and Maintenance Phase Application Objectives
Model: Receive and review the as-built model to develop an operation and maintenance model.
Application: Use the operation and maintenance model for asset queries and management of key equipment and facilities.
Management: Establish a BIM management system tailored to operation and maintenance.
Application Requirements:
Model: Model detail level LOD350.
Application: Enable virtual simulation walkthroughs and integrate on-site 3D data acquisition.
Management: Develop management processes that leverage operational BIM models.
Demolition Phase Application Objectives
Model: Receive and review the operation and maintenance model to create a demolition model.
Application: Utilize the demolition model for browsing and querying, develop demolition plans, and perform simulations.
Management: Establish a BIM management system for demolition.
Application Requirements:
Model: Model detail level LOD400.
Application: Complete demolition construction simulations and quantity statistics.
Management: Ensure all models and applications are reviewed and approved by responsible professionals.
