BIM Performance Index™

Identify hidden inefficiencies in your BIM projects before they impact delivery.

A structured diagnostic framework evaluating your project across 600 points, covering seven critical areas of BIM practice:

Library Management · Project Management · Attribute Management · Project Settings · Project Preferences · Project Structure · External Content · Model Quality · Document Structure

BIM Performance doesn’t fail suddenly. 
​It degrades over time.

Most teams notice it only when:

Slow and Difficult to manage files.

Documentation starts showing inconsistencies.

Coordination issues increase across teams

Complexity affects productivity

These are not isolated issues.


They are symptoms of deeper inefficiencies in how the BIM system has evolved.

The issue is not the software. It’s the system.

In most cases, performance issues are caused by:

Inconsistent model structure

Uncontrolled attribute growth

Fragmented library management

Lack of standardised workflows

Individually, these seem manageable.


Together, they reduce efficiency significantly across the project lifecycle.

Introducing BIM Performance Index™ (BPI)

BPI is a proprietary diagnostic framework designed to evaluate 
BIM performance across active projects.

BIM Performance Index™ provides a clear understanding of:

Where performance is breaking down

What is causing inefficiencies in Workflow

How it impacting the project delivery

What the BIM Performance Index™ reveals

1. BIM Performance Index™ Score 

(0–100)

Overall score of your File Health and Workflows based on key findings from your file.

2. Key risk areas across your project 

& workflow

Highlights of areas contributing to Performance and Operations of your file and workflow.

3. Performance, structure, and BIM readiness insights

A clear insight into current status vs industry standards and desired results.

4. High-level recommendations for improvement

Clear actionable items for Management and BIM Managers of the organisation.

The system, not the software

"We knew our files were getting slow and sluggish and always assumed it was Archicad making it slow. After the BIM Performance Index™ results, we were pleasantly surprised - the correction lay at our desk, not at GRAPHISOFT HQ in Budapest."

when you need BIM Performance Index™

When should you consider BPI?

  • Project becoming slow or difficult to manage
  • Inconsistent documentation output
  • Coordination issues across teams
  • Before scaling teams or project complexity
  • After multiple iterations or long project duration

From insight to improvement

The BPI is the first step.

Once inefficiencies are identified,
a structured optimisation approach can be defined to improve performance, workflow, and team alignment.

What it is

BIM Performance Index™ is a structured diagnostic evaluation conducted on your live Archicad project files. It assesses your BIM practice across 600 points, covering nine areas: Library Management, Project Management, Attribute Management, Project Settings, Project Preferences, Project Structure, External Content, Model Quality and Document Structure.

The output is a score from 0–100 alongside a findings report that identifies where performance is breaking down and what is causing it — written in plain language for management, not just BIM specialists.

Not quite. A generic BIM audit is typically a checklist review - it tells you what is wrong. BIM Performance Index™ goes further: it weights findings against each other, benchmarks your project against established standards, and translates the result into a score that reflects real project risk.

The score also makes it repeatable - you can run BIM Performance Index™ again after improvements and measure the change objectively.

BPI™ is designed for Archicad projects. It is conducted on your live project file, so as long as your team is working in Archicad, the evaluation can proceed regardless of version. If you are on an older version, we will flag any version-specific considerations as part of the findings.

What to expect

Once you book, the DIMENSION PLUS team will coordinate with you to receive the relevant project files. The evaluation is conducted entirely by our team - you do not need to set up anything or sit through a session. We deliver a structured findings report with your BIM Performance Index™ score, key risk areas, and actionable recommendations. A debrief call is available to walk through the findings if needed.

The evaluation typically takes 15-21 working days from the time we receive the project files, depending on file complexity. You will receive the report by email once complete. If you have a specific deadline or need for a faster turnaround, let us know when booking.

Send a file that is representative of how your team actually works, not one that has been cleaned up for the purpose. BIM Performance Index™ is most valuable when it reflects your real workflow. If you are unsure, send the file that is giving you most issues.

Yes. Project files shared for a BIM Performance Index™ evaluation are used solely for the purpose of conducting the diagnostic. DIMENSION PLUS does not share, distribute, or retain project data beyond the engagement. If your project has specific confidentiality requirements, we are happy to sign an NDA before files are shared.

Score and outputs

The score reflects the overall health of your BIM file and workflows across all nine evaluation areas. A higher score indicates a well-structured, efficient project environment. A lower score does not mean your project is failing - it means there are identifiable areas where performance can be significantly improved.

More importantly, the score tells you where the gaps are, not just that gaps exist. Each area is scored independently, so you get a clear picture of which categories need the most attention.

Both. The report is structured in two layers: a summary section with the overall score and high-level findings, written for founders and principals who need the strategic picture, and a detailed findings section for BIM Managers and senior architects who will act on the recommendations. You do not need a BIM specialist to understand the key conclusions.

Yes - and this is one of the most valuable uses of BIM Performance Index™. Running it before and after a structured improvement effort gives you an objective measure of progress. Practices that have gone through the BIM Transformation Program™ often run BIM Performance Index™ again to validate the improvements and establish a new performance baseline.

Next steps

That depends on what the findings show. Some practices address the recommendations independently using their internal team. Others choose to work with DIMENSION PLUS to implement the improvements through the BIM Transformation Program™ - a structured programme that builds the workflows, standards, and team habits that make BIM actually stick.

There is no obligation after BPI™. The report stands on its own as a diagnostic. If you want support to act on it, we are available.

If your practice is still evaluating whether to transition to BIM, the BIM Readiness Analysis™ is the more relevant starting point - it assesses whether your practice is ready for BIM and recommends the right entry path. BPI™ is designed for practices that are already working in Archicad and want to understand how well their current setup is performing.

A before and after

"My team and IT always wanted to upgrade the hardware and systems. RAM was an expense every 6 months, graphics card every year, CPU every 2 years. 

Post BIM Performance Index™, our file size reduced from 2.65 GB to 895 MB for a multi-storey residential apartment project."
