ISO 19650 Naming Convention: Fields, Codes and Examples

Clive Jordan

3 min read

An ISO 19650 naming convention gives every file on a project a name that says what it is, who made it and where it belongs - so anyone can find it in the common data environment (CDE) without opening it. Here is the convention most UK and international projects use, field by field, with examples you can copy.

The fields, in order

The UK National Annex to ISO 19650-2 sets out seven fields, separated by hyphens:

Field What it says Example
Project The project's code, set by the appointing party HLX
Originator The organisation that produced the file ABC
Volume or system Which building, zone or system it covers ZZ (all) or B1
Level or location Which floor or location 02, or XX (none)
Type What kind of information it is M3 (3D model), DR (drawing)
Role The discipline that produced it A (architect), S (structural)
Number A unique number within the rest of the name 0001

So HLX-ABC-ZZ-02-M3-A-0001 is the architect ABC's 3D model of level 02, for all zones of project HLX. The status and revision are kept as separate information on the CDE, not in the file name, so the name never changes as the file moves from work in progress to shared to published.

Common type codes

  • M2 / M3 - 2D and 3D models
  • DR - drawings
  • SP - specifications
  • RP - reports
  • SH - schedules
  • MI - minutes and action notes

Common role codes

  • A - architect
  • S - structural engineer
  • M - mechanical engineer
  • E - electrical engineer
  • C - civil engineer
  • W - contractor
  • K - client

Check your project's information standard before you start: the appointing party sets the codes, and many add their own for local needs.

Status and revision codes travel with the file, not in its name

Alongside the name, each file carries a status (what it can be used for, such as S1 "suitable for coordination") and a revision (P01, P02 while preliminary; C01 once contractual). See ISO 19650 status codes for the full list.

Four mistakes that break a naming convention

  1. Putting the status or revision in the file name. The name then changes every time the file moves, and links break.
  2. Inventing codes on the fly. If a code isn't in the project information standard, nobody else can search for it.
  3. Different conventions for models and drawings. One convention for every container keeps the CDE searchable.
  4. Checking names by eye. Let the CDE or your checks validate every name on upload, so a wrong name never gets shared.

Make the convention part of the plan

In Plannerly, each deliverable in your MIDP becomes a named file request on its task, following your naming convention - so task teams see the right name before they create the file, and nothing is renamed later. Connect Autodesk Construction Cloud or BIM 360, and a file shared there with a matching name fills its request by itself (how CDE Connect works).

Questions

ISO 19650 naming convention questions

What is the ISO 19650 naming convention?
A set of fields, separated by hyphens, that every file name on the project follows: project, originator, volume or system, level or location, type, role and number - for example HLX-ABC-ZZ-02-M3-A-0001. The UK National Annex to ISO 19650-2 sets out these fields; the project information standard sets the codes. The UK BIM Framework's guidance explains them.
Do status and revision go in the file name?
No. They're kept as information on the common data environment, so the file name stays the same as the file moves from work in progress to shared and published. Every status code explained.
Who decides the codes?
The appointing party, in the project information standard. Task teams use the codes they're given and ask for new ones rather than inventing them. Who the appointing party is.
What is the UK National Annex?
The UK's annex to ISO 19650-2, published with BS EN ISO 19650-2. It adds UK requirements, including the naming fields and the status codes. Other countries publish their own annexes, so check the one your project uses. Links to every part of ISO 19650.
Does the naming convention apply to models and drawings alike?
Yes. Every information container on the project - models, drawings, schedules, reports - follows the same convention, and each one appears by name in the task team's TIDP and the MIDP.

Surviving the seven CDEs

Connect them. Keep them in step. Stop re-uploading. Most projects run more than one common data environment, so the single source of truth quietly becomes several and you spend your week re-uploading. How to keep every CDE in step with the agreed plan, so delivered files check themselves off and the dashboards move on their own.
