01 Field reports

You already do the work. Proving it is the hard part.

Tenders are starting to ask for IFC. Clients are asking questions most teams cannot answer. The people who can do openBIM and prove it are still rare. That is the gap BIMvoice closes.

02 What BIMvoice stands for

openBIM is freedom, and BIMvoice exists to make it work worldwide. Not only to talk about it.

Freedom means two things here. First, freedom for your data: your deliverables belong to you, in open formats, never held hostage by one platform. Second, freedom from licenses: nobody should need an expensive seat to learn, test, or deliver openBIM.

Most voices in this industry have something behind the advice. A vendor. A platform. A reseller margin. BIMvoice has none. And the knowledge is free on our channels: tutorials, IFC workflows, real problems solved on camera. Go watch it, use it, test us. What students pay for is the official certification path and what the credential does for a career.

The name

BIMvoice means clarity in openBIM. A clear practical voice in all the BIM noise.

03 Where this comes from

Seven years inside Norway's biggest tunnel projects.

I am a civil engineer. I learned construction from the bottom: summers as a site laborer in Italy while earning my degree, finished in 2009. In Norway from 2013, I built my engineering career from the office up: bridge engineer on a 436 meter railway bridge, civil engineer, formwork designer, founder of my own small construction company, technical draftsman on Follobanen, BIM Lead, and finally BIM Project Engineer and Coordinator on Oslo's New Water Supply. Twelve years in Norway, ending inside the country's two biggest tunnel projects. In July 2025 I went full time on BIMvoice.

On E6 Rentvannstunnel, Oslo’s new water supply, models were not presentations. The site placed reinforcement directly from model data. When something was assembled, it was checked against the model: pipes with the right diameter, the right thickness, the right part in the right place. If the file was wrong, the site was wrong. Not theory. Scars.

In July 2025 we left Norway. We traveled six months through Southeast Asia with my wife and son, and in February 2026 we made Sibiu, Romania, home. From Sibiu the practice reaches the world: a certified buildingSMART Practitioner and Registered Training Provider, teaching what I did, with the tools I still use.

04 The official path

Foundation is the first step. Practitioner is the deep end.

Thousands hold Foundation. Practitioner is still counted in hundreds.

buildingSMART International runs the global certification program for openBIM competence. If you want an internationally recognized openBIM credential, this is currently the only path. BIMvoice takes you through it.

The official certification program
DOOR 1 · FOUNDATION Start here

Understand openBIM. Prove it with the official certificate.

The official entry certification for openBIM: ISO 19650, IFC, standards, workflows. Pass it and your name appears in the public buildingSMART registry. Anyone can verify it. That is the point.

  • Recorded training, start today at your pace
  • Exam simulations and checkpoint quizzes
  • Weekly live exam prep with Petru

Everything stays yours. Access never expires.

Ten BIMvoice students have taken the official buildingSMART Foundation exam. Ten passed. All on the first attempt.

"You set us up for the best case scenario." A student, minutes after passing

Prove you can apply openBIM. Not just talk about it.

The official buildingSMART credential that documents applied competence: you set information requirements, build the IDS, produce and check the IFC, run coordination, validate, and report issues. For years this certification lived mainly in German. It is now opening internationally, and in most countries there are still very few certified openBIM Practitioners. The earlier you earn it, the stronger the signal.

  • Recorded training, start today at your pace
  • Weekly live calls with Petru
  • Mock exams and feedback
  • Support all the way to the exam
  • Lifetime access to all non-certification BIMvoice courses, meetings, events, and resources

In most countries, Practitioner-certified professionals are still rare. That makes the credential a strong signal early.

The official openBIM Practitioner program at buildingSMART
Entry conditions

Practitioner requires the Foundation certificate, 24 hours of training with a registered training provider, and two years of documented BIM experience with openBIM exposure. Unsure whether your experience qualifies? That is exactly what the Orientation call is for.

The exam application takes time to prepare properly. Starting early builds a strong application instead of a rushed one.

The three options, plainly.

OPTION 1INVISIBLE

Do nothing, and your competence stays invisible.

OPTION 2UNVERIFIABLE

A generic course may teach useful things. But it does not put you in the buildingSMART registry.

OPTION 3VERIFIED

Or take the official path: buildingSMART certification, a Registered Training Provider, your name in the public registry.

05 Students, in their own words

Every claim on this page can be checked. Start with the people.

Foundation · passed first try

"With Petru, on the other hand, from the first few minutes, I felt that if I chose him, I would have his full support throughout the whole course. And this actually happened, from the first interactions all the way up to the exam day. After going through the materials and the quizzes several times, I felt prepared for the exam and I passed it on my first try."

Valentina BadulescuArchitect
Foundation · Finland

"I chose Petru Conduraru and BIMvoice as the training provider. The training material Petru created on the subject was excellent, and his helpfulness and commitment are at an admirable level. So, was it worth the time and money? Absolutely, precisely because of the excellent training material."

Markus JärvenpääGroup Manager (BIM Development) at Granlund
Foundation · exam day

"By the time exam day rolled around, I genuinely felt ready. I can honestly say that Petru is the best teacher I could have asked for. He has a unique ability to take dry, technical BIM standards and explain them with absolute clarity and real-world context."

MichaelCEO @ Ecore Energy Design
Foundation · Norway

"It was focused on the exam and was very valuable in helping me develop the necessary understanding and preparation. I gained a much clearer understanding of ISO 19650 and openBIM, and I now see how everything fits together."

Glenn ThomasFoundation certified

"The Foundation certification has deepened my understanding of interoperability, IFC, and the collaborative workflows that make truly open, vendor-neutral BIM possible. Looking ahead, I'm excited to continue this journey by pursuing the Practitioner certification."

Job Placencia NavarroVDC | Digital Project Manager

06 For projects and organizations

openBIM support, delivered by people who did it on site.

Training and project work are the same practice here. We teach openBIM because we use it, and we use it because we teach it. Fixed scope, fixed deliverables, no open-ended engagements.

S.01

The openBIM Readiness Audit

One company or one project: BIM deliverables, IFC quality, information requirements, IDS usage, exchange workflows. You get a written report with findings ranked by impact, a 90 minute workshop with your team, and a roadmap. If you are starting or fixing a project, the audit's natural next step is a strategy sprint that leaves you with a working openBIM execution setup.

Fixed scope, fixed price, delivered in days. Investment is discussed in the first conversation.

S.02

Fractional openBIM Coordination

A senior openBIM information manager on your project, part time: model checking routines, IFC quality control, IDS validation, issue management. This is the work Petru did on Oslo’s New Water Supply. Strictly limited engagements.

A capped monthly engagement for projects that need senior openBIM support without a full-time hire.

S.03

Group openBIM Training

Your team, your projects, your deliverables: IFC in practice, IDS, model checking, coordination workflows. Including hands-on workshops on the free openBIM toolset: Bonsai, IFClite, IDS editors. If certification is the goal, the team follows the official Foundation path together.

Fixed scope per group. One invoice. No licenses required to start.

One call, one honest answer

Start with a conversation.

One call about your situation, your market, your level. For certification: how the training works, what is included, how exam preparation is handled. For organizations: what your project, team, or strategy needs. You leave with a clear picture either way. Investment and details are discussed on the call, nowhere else.
