# Resolve BIM Model Clashes

*/Problems/Resolve_BIM_Model_Clashes*

## Problem Overview

BIM coordinators and Virtual Design and Construction managers spend hours reconciling intersecting geometry across architectural, structural, and mechanical models. When multiple disciplines work in parallel, an updated HVAC duct inevitably collides with a structural beam or plumbing line. Current clash detection software excels at identifying these intersections but leaves the actual resolution to humans, generating massive reports filled with thousands of spatial conflicts that must be evaluated manually.

Resolving these clashes requires cross-disciplinary coordination meetings where engineers negotiate which component moves, followed by manual redrafting in authoring tools. A single change in pipe diameter or ceiling height ripples through the entire project, instantly spawning hundreds of new clashes. The manual routing logic needed to step around an obstruction without violating building codes, clearance requirements, or fluid dynamics constraints makes spatial reconciliation highly labor-intensive.

Existing rule-based routing plugins fail because they lack spatial awareness of the entire building system and cannot weigh the cascading cost implications of moving a structural support versus rerouting a conduit. This forces highly paid engineers to act as spatial arbitrators, manually tweaking 3D geometry piece by piece instead of focusing on system optimization and building performance.

## Problem Severity Frequency

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Severity**: 4
**Frequency**: continuous
**Budget Reality**:
- **Price Ceiling**: ~$15k–30k/yr — caps near existing coordination software budgets and fractional FTE savings, rather than capturing the full cost of pain
- **Who Controls Spend**: Director of VDC or Project Executive approves, BIM Manager evaluates
- **Existing Budget Line**: true
- **Switching Cost From Status Quo**: high: requires deep integration with entrenched authoring tools like Revit and forces changes to multi-stakeholder coordination routines
**Regulatory Risk**: moderate
**Time Cost Per Event**: ~4–8 hours
**Money Cost Per Event**: ~$500–2,000
**Annual Cost Per Affected Entity**: ~$80k–150k all-in

## Problem Why Now

The demand for higher energy efficiency and smart building infrastructure drastically increases the density of mechanical, electrical, and plumbing systems housed within standard ceiling plenums. According to AGC ~2023 construction surveys, firms face a severe and ongoing shortage of specialized Virtual Design and Construction coordinators capable of untangling these dense networks. As project timelines compress, the traditional method of resolving thousands of clashes via weekly cross-disciplinary coordination meetings creates a critical bottleneck that delays fabrication.

Prior automation attempts relied on rigid, rule-based parametric routing that failed immediately upon encountering non-standard geometry or conflicting clearance requirements. The technological lever unlocking automated resolution today is the maturation of geometric deep learning and graph neural networks. Emerging over the past two years, these models natively process 3D topological graphs, allowing systems to calculate the cascading structural and cost implications of rerouting a duct network rather than merely highlighting the intersection.

## Problem Current Solutions

**Status Quo**: BIM coordinators run clash detection tools to generate massive reports of intersecting geometry, then host cross-disciplinary meetings where engineers manually negotiate component movements and individually redraft routes in authoring software.
**Workarounds**:
- exporting clash reports to spreadsheets
- lengthy cross-disciplinary coordination meetings
- manual piece-by-piece geometry tweaking
- ignoring soft clearance clashes until construction
**Named Tools In Use**:
- [Autodesk Navisworks](/Products/Autodesk_Navisworks)
- [Autodesk Revit](/Products/Autodesk_Revit)
- [Autodesk BIM Collaborate](/Products/Autodesk_BIM_Collaborate)
- [Revizto](/Products/Revizto)
- [Solibri Office](/Products/Solibri_Office)
**Why Insufficient**: Current coordination platforms identify spatial intersections but lack the global system awareness required to weigh the cascading cost implications of moving specific components. They rely entirely on human engineers to act as spatial arbitrators and manually calculate code-compliant, collision-free rerouting paths.

- [Autodesk Revit](/Problems/Resolve_BIM_Model_Clashes/Competitors/Autodesk_Revit)
**Substitutes**:
- Cross-disciplinary coordination meetings
- Exporting clash reports to spreadsheets
- Manual piece-by-piece geometry tweaking
- Ignoring soft clearance clashes until construction
**Position Axes**:
- Detection-only vs. Automated resolution
- Local component logic vs. Global system awareness
**Market Dynamics**: The market is shifting from isolated desktop collision detection software toward centralized cloud-based issue tracking platforms, with emerging computational design logic attempting localized automated MEP routing.
**Competition Concentration**: Incumbents heavily concentrate in the detection-only and local component logic quadrant, offering platforms that aggregate models and flag thousands of intersections without generating rerouting paths. Substitutes like cross-disciplinary coordination meetings occupy the global system awareness space but rely entirely on manual human arbitration to negotiate conflicts. The quadrant combining automated resolution with global system awareness remains highly sparse, as existing rule-based plugins lack the computational capacity to weigh cross-disciplinary cost implications and holistic spatial constraints simultaneously.
