BIM Clash Detection & Coordination Services

01 — The Challenge

Modern construction projects involve multiple disciplines working simultaneously within increasingly complex and constrained spaces. Even small coordination issues can lead to major site delays, redesign, and additional costs.

Common challenges include:

• HVAC ducts clashing with structural beams

• Pipes conflicting with electrical containment

• MEPF services competing for limited ceiling space

• Equipment access and maintenance clearance issues

• Structural openings not aligned with MEP requirements

• Architectural and MEP coordination gaps

• Multiple design revisions creating new conflicts

• Large numbers of clashes that are difficult to prioritize

• Clashes identified only after construction begins

• Lack of clear responsibility for resolving coordination issues

VDEC identifies these conflicts digitally, prioritizes them based on project impact, and supports project teams in resolving them before they become site problems.

02 — VDEC Solution

Our BIM Clash Detection & Coordinationapproach combines automated clash detection with engineering-based review and constructability analysis.

We coordinate multidisciplinary models to identify:

Hard Clashes

Physical conflicts where two or more elements occupy the same space.

Soft Clashes

Insufficient clearance around equipment, services, access zones, maintenance areas, or required installation spaces.

Workflow / 4D Clashes

Conflicts related to construction sequencing, temporary works, installation access, or planned construction activities.

Constructability Issues

Potential installation or maintenance problems that may not be identified through automated geometric clash detection alone.

04 — Our Process

01. Model Collection & Review

We collect and review the latest Architectural, Structural, HVAC, Electrical, Plumbing, Fire Protection, and other relevant BIM models.

02. Model Validation

Before running clash detection, we review model integrity, coordinates, levels, model versions, element classifications, and overall suitability for coordination.

03. Federated Model Creation

Individual discipline models are combined into a coordinated federated BIM environment.

04. Clash Detection

Automated clash tests are performed based on project requirements, discipline combinations, tolerance values, and defined coordination rules.

05. Engineering & Constructability Review

Our BIM team reviews detected issues beyond simple geometric intersections, considering installation, access, maintenance, clearance, sequencing, and constructability.

06. Clash Classification & Prioritization

Clashes are grouped and prioritized based on severity and project impact, helping project teams focus on critical issues first.

07. Coordination & Resolution

Identified issues are communicated to the responsible discipline or design team. Updated models are reviewed to confirm that clashes have been resolved.

08. Final Validation

A final coordination review is performed to verify that critical clashes have been addressed and the coordinated model is ready for the next project stage.

05 — Software & Technology

Our BIM coordination teams work with industry-standard technologies, including:

Autodesk Navisworks | Autodesk Revit | AutoCAD | Autodesk Construction Cloud (ACC) | BIM 360

We can also work within client-specific BIM Execution Plans, coordination standards, Common Data Environments, clash matrices, and issue-management workflows.

06 — Benefits

Identify Problems Early

Detect coordination issues digitally before they reach the construction site.

Reduce Rework

Resolve conflicts during design and coordination instead of during installation.

Improve Constructability

Evaluate whether coordinated systems can actually be installed, accessed, maintained, and constructed.

Reduce Construction Risk

Minimize unexpected site conditions, redesign, delays, and coordination-related disruptions.

Better Multidisciplinary Coordination

Create a common digital environment where Architecture, Structure, and MEPF disciplines can be coordinated effectively.

Prioritize Critical Issues

Focus project teams on high-impact clashes instead of spending time on low-priority or duplicate issues.

Improve Site Execution

Provide construction teams with coordinated information that supports efficient installation.

Improve Project Communication

Clear clash reports and visual coordination outputs make technical issues easier for project stakeholders to understand and resolve.

Better BIM Model Quality

A coordinated model provides a more reliable foundation for construction documentation, fabrication, installation, and handover.

07 — Example Project

BIM Clash Detection & MEPF Coordination for a High-Rise Development

Project Type: High-Rise Commercial / Mixed-Use Development
Scope: BIM Coordination + Clash Detection + Constructability Review
Disciplines: Architecture + Structure + HVAC + Electrical + Plumbing + Fire Protection
LOD: 350

VDEC Approach

VDEC received multidisciplinary BIM models and established a federated coordination environment for the project.

The team performed systematic clash detection across MEPF services, structural elements, architectural components, ceiling spaces, shafts, plant rooms, and service zones.

Detected issues were categorized by discipline and severity. Critical clashes affecting construction and installation were prioritized for resolution.

VDEC then reviewed updated models and performed subsequent coordination checks to verify that identified issues had been resolved.

Outcome

The coordinated BIM workflow helped the project team identify conflicts before construction, improve service routing, reduce coordination risks, and provide better construction-ready information for site execution.

08 — Coordinate Before You Construct

Every unresolved clash has the potential to become a site delay, redesign, additional cost, or rework.

VDEC helps project teams move from reactive problem-solving to proactive digital coordination by identifying and resolving conflicts before construction begins.

From BIM Clash Detection and multidisciplinary coordination to constructability review and final model validation, we help make complex projects more coordinated, predictable, and buildable.
