BIM audit and consulting: find out where your team loses hours and what to automate first
We review your models and measure how your team works. In four weeks you get a diagnosis backed by numbers and a prioritized plan: what to fix, what to standardize and what to automate first, with the estimated savings of each action.

In short
Zeist's BIM audit is a four-week diagnosis that combines two reviews: a model audit, which checks the technical quality of the files — naming, coordinates, model health, information and consistency between model, drawings and quantities — and a process audit, which measures where hours are lost, which tasks are repeated and which standards are missing. The result is a report with findings prioritized by impact and effort, and a plan to fix, standardize and automate. It isn't a certification: it's a decision-making tool for technical leadership.

A BIM audit is for your firm if…
The same review comments keep coming back
Deliverables return with the same comments: quantities that don't add up, formatting, outdated sheets.
Every project comes out different
Deliverable quality depends on who did the work, not on a standard everyone follows.
A bid with BIM requirements is coming up
You need to know whether your models and workflow meet what will be required, such as the client's information requirements under ISO 19650.
Models are slow or keep getting corrupted
The team loses time waiting on the model and nobody knows exactly why.
You want to automate but don't know where to start
There are plenty of ideas and little time. You need to know which one gives back the most hours before you invest.
The team works overtime on every deliverable
The effort is there; what's missing is knowing where it goes.
What we review in the BIM audit
Two fronts, with a checklist we adapt to your standards and project types:
Model quality
Naming, file structure, shared coordinates, levels and grids, warnings, imported CAD and families.

Which tasks depend on a single person and what happens to the deliverable when that person is away.
Automation opportunities
Repetitive tasks that are candidates for Dynamo or a plugin, with the hours per year they consume today.

- 01
Timeline: Week 1
Scope
We choose two or three representative projects and the disciplines included, and define what leadership needs to know.
- 02
Timeline: Week 2
Model review
We run the model checklist, with automated tools wherever possible.
- 03
Timeline: Week 3
Workflow analysis
Short interviews with the team and observation of a real deliverable. We measure times.
- 04
Timeline: Week 4
Report and plan
Prioritized findings, a three-front plan and a baseline to measure progress. We present it to leadership.
- 05
Timeline: Afterwards
Implementation (optional)
You can carry out the plan with your team or with us: standards, templates, Dynamo scripts and plugins.
What your firm gets
- A diagnosis backed by numbers: hours per task, review rounds and model health
- Findings prioritized by impact and effort
- A three-front action plan: fix, standardize and automate
- The estimated savings of each recommended automation
- A baseline of indicators to measure progress
- A results presentation for leadership
Deciding with an audit or without one
| Decision | With an audit | Without an audit |
|---|---|---|
| What to automate first | What gives back the most hours, measured | Whatever feels urgent |
| Recurring review comments | The root cause is addressed | Each symptom is patched |
| Tool investment | Where there's a return | Wherever someone asked |
| Progress | Measured against a baseline | No reference point |
| Client requirements | Gaps identified up front | Discovered in review |

BIM Audit: What It Is, What It Checks (Full Checklist) and When Your Firm Needs One
What a BIM audit is: auditing the model versus the process, the full checklist, what the report delivers and when your firm should do one.
How to standardize BIM processes at your company without slowing production down (2026 guide)
What to standardize first, why BIM rollouts fail, how to handle team resistance, and a 90-day plan that works while production keeps running.
Rework on site: the 12-18% of the budget nobody measures (and how to cut it from the office)
Rework on site costs 12-18% of the budget and almost nobody measures it. Why it starts in design, and what you can fix from the office.
Slow Revit Model: Why It's So Heavy and How to Audit It Automatically Before It Stalls Your Team
Why your Revit model gets heavy and slow: warnings, imported CAD, too many families and views, and how to audit it before each submittal.
Frequently asked questions
What is a BIM audit?
A structured review of how a firm produces its projects in BIM: the quality of its models and the efficiency of its workflow. It ends with a report of prioritized findings and a plan to fix, standardize and automate.
How long does the audit take?
Four weeks for a scope of two or three representative projects: scoping, model review, workflow analysis and final report.
What do you need from our team?
Access to the models of the selected projects, short interviews with key people and the chance to observe a real deliverable. It's designed not to slow down production.
Does the audit help with ISO 19650 or public-sector BIM requirements?
It identifies the gaps between how you work today and what the client's information requirements demand. It isn't a certification, but it tells you what to fix before the next bid.
What happens after the audit?
You have a prioritized plan. You can carry it out with your team or with us: standards, templates, Dynamo scripts and custom plugins.
Is it on-site or remote?
Remote, for firms anywhere. Reviews, interviews and the results presentation are all done online.
