There is no shortage of BIM tools. Yet deciding the shape of a single reinforcing bar is still done by a person.
We cover both tool comparisons and regulatory trends. A claim needs evidence, so we cite published specifications, vendors' own documentation, and government sources.
VN · VietnamPublished September 8, 2026Vietnam's BIM mandate: what changed on 1 July 2026
BIM is now mandatory for every new building of Grade II or higher. Who is covered, what must be submitted in which format, and where the discipline split is written down — compiled from primary sources.

TECH · Technology2D and 3D — the distance between quantities · 3/3Published August 27, 2026One building, two quantities
Count the same building four ways and four numbers come back. The problem was never that they differ — it was that the difference had no name. This closing part does not ask anyone to change the standard. It asks for one more column beside it.

TECH · Technology2D and 3D — the distance between quantities · 2/3Published August 24, 2026What the waste factor hid
Whatever could not be computed has been covered by a single waste factor, and the method has largely worked. But inside that one number sit things of quite different kinds — what was assumed because it could not be computed, the offcuts genuinely lost, and quantities missed altogether.

TECH · Technology2D and 3D — the distance between quantities · 1/3Published August 21, 2026Why reinforcement is hard to count
Same building, same drawing — and yet the rebar quantity comes out differently at every firm. Not because anyone is wrong. Concrete and formwork end in multiplication, but how many metres one bar runs is never written on the drawing.

TECH · TechnologyPublished August 20, 2026Fewer people left to read the drawings
What is disappearing fastest from construction is people — and what goes with them is not only hands but the eyes that read a drawing written in symbols. We size that with statistics first, then look at one scene showing how it plays out.

TECH · TechnologyPublished August 18, 2026Where do you start with rebar BIM?
The reason the first step never gets decided is not a missing tool. It is that the person who knows rebar detailing works in 2D, and the person fluent in 3D barely knows detailing. Here is a four-step path that does not require modelling the whole building.

TECH · TechnologyPublished August 12, 2026Both drawings are correct. The problem is that they end up in the same place on site
A column section and a beam section are each accurate. But where the two members meet, their rebar competes for the same space. A 2D review cannot show it, and it usually surfaces only after the cage is tied — on site.

You can raise a wall in Revit with a sentence. Why nobody sells rebar that way yet is answered by the API signature itself.

Exposed column bases are still resolved in two dimensions. Model the shape for real and the clash check itself becomes three-dimensional.
