What you will learn, free

Twelve lessons. One corridor. Real models.

Twelve free lessons by e-mail, two from each of the six workshops of the IFC Infrastructure Masterclass, one every two days. Each lesson gives you the key ideas, a real example from our IFC 4.3 corridor and one thing to try yourself with free tools.

The whole corridor in an IFC viewer: road, bridge, railway, river, power line, depot and tunnel01 · The standards

BIM for infrastructure

Horizontal is not vertical: alignment, map and terrain instead of storeys and a plot. Who writes the rules, and which standard does which job.

1Your road is not a building2IFC builds, CityGML shows, LandInfra lays out

Remember: data outlives software. A bridge lives 100 years.

Twelve IFC 4.3 models on one map, labelled02 · The model

Infrastructure modelling

Models, not drawings. Twelve models, one family, one map: from the terrain and the ground to every discipline.

3Twelve models, one map, nothing moved by hand4Five days to build, a hundred years to keep

Remember: terrain and ground first. Every volume and every cost depends on them.

Bearings at abutment A1, ready for handover to asset management03 · The use

Model use cases

Sixteen jobs, four phases, from the first survey to the last inspection. One model cannot be perfect for every job.

5One pier, four jobs, four shapes6From the file to the concrete

Remember: the site reads numbers. Station, volume, concrete, date, tolerance.

IFC file as plain text with line #252, pier wall P1, highlighted04 · The objects

IFC 4.3 fundamentals

An IFC file is plain text. Read one line like a sentence, find the right class and PredefinedType, follow the links.

7An IFC file is a recipe, not a picture8The pier does not know where it lives

Remember: meaning lives in the links. 18 relations around one pier.

Pier P1 in Bonsai: GlobalId, PredefinedType and its bridge part05 · The data

Core concepts of IFC 4.3

Two lines put the model on the map. Where properties, quantities, materials and codes belong, so they survive the export.

9What your file promises, and where it lands10Describe the shape, pack the data

Remember: check before you send. Syntax, schema, rules, practice.

A web tool built with one prompt: every pavement layer of road R1 with thickness and material06 · The agent

AI agents for openBIM

Same brain, but the agent has hands: it reads IFC, writes IDS rules, runs the checks and builds small tools in your folder.

11Your first AI agent12The openBIM loop with your agent

Remember: AI drafts. openBIM checks. You decide.

One corridor. Twelve IFC 4.3 files.

Bridge, road, railway, tunnel, river, power line and utilities on one map, each in its own IFC 4.3 file. Every example in The Alignment comes from here.

Why now

Clients already ask for IFC 4.3.

IFC 4.3 is an ISO standard (ISO 16739-1:2024) with 876 classes, most of the new ones for infrastructure. Road, rail and bridge owners are writing it into their requirements.

NO

Bane NOR

All models in IFC 4.3 or newer (2024).

Approvals in IFC 4 or 4.3, IFC 2×3 only for now (2026).

US

From the IFC Infrastructure Masterclass

Taught live. Tested in real projects.

“The most valuable thing I gained was finally understanding the structure of an IFC 4.3 file. It was a topic I had struggled with for some time, and the course helped me connect all the pieces.”

Margarita Sánchez Baizán
Margarita Sánchez BaizánBIM Process & iTWO Specialist, Swietelsky

“One of the best openBIM trainings I have received. It was focused on infrastructure and linear projects rather than buildings, with examples clearly based on railway and road models.”

Pilar Jiménez Abós

“This course helped me see IFC beyond a file exchange format. It has given me a clear methodology for applying openBIM in our infrastructure projects in Indonesia.”

IFC Infrastructure Masterclass. Edition 3 starts in Q1 2027.

The Alignment gives you the foundations for free. Edition 3 of the IFC Infrastructure Masterclass goes deeper, live and in a new format, built around four things:

1More correct filesIFC that is right before it leaves your desk.
2More controlYou know what is in your model and you check it yourself.
3openBIM and open source, used betterMore out of open standards and free tools across the workflow.
4Your own appsSmall tools for your own workflow, built by you.

Questions

Before you subscribe

What is The Alignment?

A free newsletter on practical BIM for infrastructure: IFC 4.3, openBIM workflows, AI and automation. It starts with twelve free lessons by e-mail, two from each of the six workshops of the IFC Infrastructure Masterclass, one every two days. Then it continues once a week with practical tips from real projects.

Is it really free?

Yes. No payment, no trial. You can unsubscribe with one click from any e-mail.

Do I need to know IFC or openBIM already?

No. The course starts from the fundamentals of infrastructure data and builds up. If you are experienced, you will structure what you know and pick up practical approaches you have not seen in the documentation.

Will I hear about Edition 3 of the Masterclass?

Yes. Edition 3 of the IFC Infrastructure Masterclass starts in Q1 2027, in a new format. The Alignment subscribers hear first, before public enrolment, and get a limited, better price and invitations to live events.

How is it different from the Masterclass?

The Alignment teaches the foundations by e-mail, for free. The IFC Infrastructure Masterclass is taught live and goes deeper. Edition 3 starts in Q1 2027, and subscribers hear first, with a limited, better price.

Why the name?

In IFC 4.3 the alignment is the backbone: every road, railway and bridge is placed along it, and stations work like house numbers along the road. Get it right and everything else falls into place.
