BIM Design Validation Services

01 — The Challenge

As projects become more complex, reviewing large volumes of design information across multiple disciplines becomes increasingly difficult.

Common challenges include:

• Design information spread across multiple drawings and models

• Inconsistencies between 2D drawings and BIM models

• Design elements that do not align with project requirements

• Missing or incomplete model information

• Architectural, structural, and MEPF coordination gaps

• Design changes not reflected across all deliverables

• Inconsistent levels, grids, dimensions, and locations

• Incorrect or incomplete BIM parameters

• Constructability concerns identified late in the project

• Difficulty verifying compliance with BIM standards and project requirements

• Large volumes of information making manual review inefficient

VDEC provides a structured BIM Design Validation process to identify these issues before they impact downstream coordination, documentation, procurement, or construction.

02 — VDEC Solution

Our BIM Design Validation service combines model-based analysis, engineering review, multidisciplinary coordination, and structured quality control.

We validate designs across several key areas:

Design Intent Validation

• Review model against approved design information

• Verify geometry and design intent

• Check levels, grids, dimensions, and locations

• Identify discrepancies between drawings and models

Model Quality Validation

• Model completeness

• Element accuracy

• Family and component validation

• Parameters and data

• Naming and classification

• Model structure and organization

Multidisciplinary Validation

• Architecture vs. Structure

• Architecture vs. MEPF

• Structure vs. MEPF

• HVAC vs. Electrical

• Plumbing vs. Fire Protection

• Equipment and service interfaces

Constructability Validation

• Spatial requirements

• Service clearances

• Equipment access

• Installation feasibility

• Structural openings

• Shafts and risers

• Plant rooms and service zones

BIM Standards Validation

• LOD requirements

• BIM Execution Plan compliance

• Modeling standards

• Naming conventions

• Information requirements

• Client-specific BIM standards

Our objective is to provide project teams with confidence that the design information is accurate, coordinated, complete, and suitable for its intended project stage.

04 — Our Process

01. Project Requirement Review

We review the project brief, design requirements, BIM Execution Plan, LOD requirements, specifications, project standards, and intended BIM uses.

02. Model & Document Collection

We collect the latest Architectural, Structural, MEPF, specialist models, drawings, specifications, schedules, and supporting information.

03. Model Health Check

The BIM model is reviewed for completeness, structure, geometry, naming, parameters, coordinates, levels, and overall model integrity.

04. Design Validation

The BIM model is compared against approved design information to identify discrepancies, missing elements, incorrect geometry, and design inconsistencies.

05. Multidisciplinary Review

Individual discipline models are federated and reviewed to identify coordination gaps, interfaces, clashes, and spatial conflicts.

06. Constructability Review

We assess critical areas for installation feasibility, access, clearances, structural interfaces, service routing, and construction practicality.

07. Issue Classification

Identified issues are categorized and prioritized based on severity, discipline, location, and potential impact on the project.

08. Resolution & Revalidation

Updated information is reviewed to confirm that identified issues have been addressed correctly.

09. Final Validation

A final review is completed and the validated model and associated reports are delivered to the project team.

05 — Software & Technology

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

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

We can also work within client-specific BIM Execution Plans, model-checking requirements, templates, standards, Common Data Environments, and project information requirements.

06 — Benefits

Identify Design Issues Early

Find inconsistencies and missing information before they affect construction.

Improve Design Quality

Verify that model information accurately represents the intended design.

Reduce Coordination Risk

Identify multidisciplinary conflicts and interface issues before construction.

Improve BIM Model Reliability

Ensure models contain the appropriate geometry and information for their intended use.

Support Better Decision-Making

Give project stakeholders a clearer understanding of design quality and outstanding issues.

Reduce Rework

Resolve design and coordination issues before they propagate into documentation and construction.

Improve Constructability

Validate whether critical design elements can be practically installed and executed.

Improve BIM Compliance

Verify models against project-specific BIM standards, LOD requirements, and information requirements.

Better Project Handover

Create a more reliable digital information base for subsequent project stages.

07 — Example Project

BIM Design Validation for a Large Commercial Development

Project Type: Commercial / Mixed-Use Development
Scope: BIM Design Validation + Multidisciplinary Coordination + Constructability Review
Disciplines: Architecture + Structure + HVAC + Electrical + Plumbing + Fire Protection
LOD: 350

VDEC Approach

VDEC performed a comprehensive BIM Design Validation review across the project's multidisciplinary models.

The team first conducted a model health and quality review, followed by comparison against approved drawings and design information. Key areas, including plant rooms, shafts, ceiling zones, structural openings, service corridors, equipment areas, and major MEPF interfaces, were then reviewed for coordination and constructability.

Identified discrepancies and issues were categorized by discipline and priority. Updated models were subsequently reviewed to confirm resolution.

Outcome

The validation process provided the project team with greater confidence in the accuracy, completeness, coordination, and constructability of the BIM information before it progressed further into construction documentation and site execution.

08 — Validate Before You Build

Design validation is more than checking whether a model looks correct. It is about ensuring that the design information is accurate, coordinated, complete, and ready for its intended purpose.

VDEC combines BIM expertise, engineering knowledge, multidisciplinary coordination, and structured quality controlto help project teams identify risks before they become costly problems.

From model validation and design compliance to coordination and constructability review, we help you move forward with greater confidence.
