Article 2.6 Coordination Modelling

• The integration process aligns the geometry and data from each discipline, enabling stakeholders to detect overlaps or spatial conflicts early.

• One of the primary purposes of coordination modelling is to perform clash detection, where software algorithms identify instances of elements from different models interfering with one another (e.g. a ventilation duct intersecting with a structural beam).
• Once clashes are detected, the team collaborates to resolve them by adjusting the design before construction begins. This proactive approach eliminates on-site surprises reduces costly, drawn out, adjustments.

• Coordination modelling also involves frequent meetings where a cross-section of representatives from all those involved in the construction project review identified clashes and collaboratively decide on solutions.
• These meetings foster interdisciplinary collaboration, promoting more efficient and holistic management for the life cycle of the construction project.

• Coordination modelling ensures that models from different disciplines share a common coordinate system and follow consistent data standards.
• This standardization helps maintain the accuracy of spatial relationships and reduces discrepancies between models.

• Using coordinated BIM models, stakeholders can visualize the integrated project in 3D, identifying potential conflicts more intuitively.
• Advanced simulations (e.g. 4D scheduling and 5D cost analysis) can also be performed on coordinated models to more comprehensively plan construction sequences and consolidate budget forecasts.

• Coordination modelling software also have the critical mass to generate reports detailing location, type, and severity of clashes, helping teams prioritize resolutions.
• Documentation of coordination efforts ensures transparency and traceability throughout the project lifecycle.

• Reduced Errors and Rework: By detecting clashes early, teams can prevent complications that would otherwise arise during construction.
• Improved Collaboration: Facilitates open communication between architects, engineers, and contractors, fostering teamwork.
• Time and Cost Efficiency: Minimizes construction delays and unexpected expenses related to on-site corrections.
• Enhanced Quality Control: Maintains high standards of accuracy and consistency in complex, multi-disciplinary projects.
• Risk Mitigation: Reduces risks associated with design flaws, material mismatches, and spatial conflicts.

Article 2.7 Simulation Modelling

• Improved Decision-Making: Provides data-driven insights to guide design, engineering, and construction decisions.
• Risk Reduction: Identifies potential issues before construction begins, minimizing costly errors and changes.
• Sustainability and Efficiency: Enhances building performance by analysing energy use, resource efficiency, and environmental impact.
• Cost and Time Savings: Optimizes construction planning and resource allocation, leading to more predictable project outcomes.
• Enhanced Building Performance: Supports lifecycle analysis and facilities management by simulating long-term behaviour and maintenance needs.

Article 2.8 Visualization Modelling

• Makes design concepts understandable for all stakeholders, including those without technical backgrounds.
• Reduces misinterpretations and improves collaboration.

• Increases client involvement and satisfaction by allowing them to see and interact with the design early in the process.

• Helps verify the feasibility of the design before construction begins.
• Detects visual inconsistencies, space issues, and accessibility concerns.

• Provides high-quality visual content for proposals, approvals, and marketing materials.
