Multi-Agent BIM Clash Detection & Resolution Digital Worker
Deploys 10 specialized AI agents in a 9-stage DAG-based workflow to analyze federated BIM models, detect geometric clashes and clearance violations, assess cost and schedule impacts, check regulatory compliance, evaluate sustainability implications, and generate prioritized resolution recommendations with feasibility assessments. Produces comprehensive clash reports with resolution options, cost-benefit analysis, and implementation roadmaps.

AI Agents
Specialized autonomous agents working in coordination
Workflow Orchestration Agent
Complex 9-stage BIM analysis requires coordinating 10 specialized agents with dependencies, parallel execution opportunities, and synchronization points while maintaining comprehensive audit trails.
Core Logic
Manages the complete DAG-based workflow with stage dependencies including initialization, context gathering, BIM analysis, safety analysis, compliance checking, impact assessment, sustainability analysis, resolution planning, and synthesis. Coordinates parallel agent execution where dependencies allow, handles agent-to-agent communication including delegation, queries, responses, and handoffs, and synthesizes stage outputs into unified deliverables. Tracks execution metrics per stage.
BIM Analysis Agent
Federated BIM models from multiple disciplines require geometric analysis to detect physical clashes, clearance violations, and spatial conflicts between building systems.
Core Logic
Parses IFC and native BIM formats to extract element geometry, classifications, and spatial relationships. Implements Octree spatial indexing for efficient clash detection across large models. Identifies geometric clashes (hard clashes), clearance violations (soft clashes), and workflow conflicts (4D clashes). Classifies clashes by discipline pair, severity, and location with 3D coordinates and grid references. Processes element metadata to support downstream impact analysis.
Cost Estimation Agent
Clash resolution requires cost context to prioritize fixes and select optimal solutions. Teams need NPV analysis, probabilistic cost ranges, and ROI calculations to justify coordination investments.
Core Logic
Calculates resolution costs using RICS NRM databases and current material/labor rates for each clash. Performs NPV analysis for resolution options, Monte Carlo simulation for cost uncertainty quantification, and ROI calculations comparing resolution investment against rework prevention benefits. Generates cost impact summaries by discipline, severity, and resolution strategy enabling prioritized coordination decisions.
Schedule Impact Agent
Clashes affect construction schedules through rework, redesign cycles, and sequencing conflicts. Schedule planning must account for clash resolution time and critical path impacts.
Core Logic
Analyzes clash impacts on construction schedules using CPM algorithms and float calculations. Identifies clashes affecting critical path activities, quantifies schedule delay risks in days, and evaluates milestone impacts. Assesses 4D sequencing conflicts where installation sequences create temporary clashes. Generates schedule risk assessments with confidence ranges and recommends resolution timing to minimize schedule disruption.
Resolution Advisory Agent
Detected clashes require resolution recommendations that balance feasibility, cost, schedule, and design intent. Teams need multiple options with trade-off analysis to support coordination decisions.
Core Logic
Generates resolution options for each clash considering element relocation, rerouting, resizing, and sequencing alternatives. Assesses feasibility of each option against structural, MEP, and architectural constraints. Provides cost and schedule estimates per option, identifies affected trades, and recommends optimal resolution based on weighted criteria. Supports multi-option decision making with comparison matrices and supporting evidence.
Regulatory Compliance Agent
Clash resolutions must maintain compliance with UK Building Regulations, BS standards, and industry requirements. Non-compliant resolutions create downstream regulatory issues.
Core Logic
Validates clash resolutions against applicable regulatory frameworks including UK Building Regulations (Part B, L, M, etc.), BS 8300 accessibility, BS EN fire standards, and water sector-specific requirements. Identifies compliance constraints on resolution options, flags non-compliant proposals, and recommends compliant alternatives. Generates compliance verification documentation for audit purposes.
Safety Assessment Agent
Some clashes and their resolutions have safety implications including access restrictions, fall hazards, and construction sequence risks. Safety impacts must be assessed before finalizing resolutions.
Core Logic
Evaluates safety implications of detected clashes and proposed resolutions. Identifies hazards created by clashes such as restricted access routes, fall edges, and equipment conflicts. Assesses safety impacts of resolution options including temporary works, access requirements, and construction sequence changes. Generates PPE requirements and safety control measures for resolution implementation. Maps safety zones affected by clash locations.
Sustainability Assessment Agent
Clash resolutions involving material changes, rework, or waste have carbon and sustainability implications. Environmental impacts should inform resolution prioritization and option selection.
Core Logic
Calculates embodied carbon impacts of clash resolutions including material replacement, waste generation, and additional fabrication. Performs lifecycle analysis for resolution options, assesses BREEAM credit implications, and evaluates Scope 1-3 carbon footprint changes. Recommends resolutions minimizing environmental impact and identifies circular economy opportunities for salvaging clashing elements.
Real-Time Context Agent
Clash resolution feasibility depends on current site conditions including weather, material availability, workforce capacity, and supply chain status. Static analysis may recommend infeasible solutions.
Core Logic
Integrates real-time data feeds including weather forecasts, material price volatility, supply chain health indicators, workforce skill availability, and regulatory updates. Adjusts resolution feasibility based on current lead times, resource constraints, and site conditions. Flags resolutions requiring unavailable materials or skills, and identifies supply chain risks affecting implementation timelines.
Report Generator Agent
Clash analysis must be documented for coordination meetings, client reporting, and design team action. Multiple stakeholders require tailored views of clash data and resolutions.
Core Logic
Compiles comprehensive clash documentation including executive summaries for management, technical clash registers for coordination teams, discipline-specific reports for design consultants, and visual clash maps for site teams. Generates PDF reports, Excel clash registers, updated BIM models with clash markup, and PowerPoint presentations for coordination meetings. Provides filtering and sorting by severity, discipline, location, and status.
