A folder structure and file-naming rule for project documents
A project manager covering a colleague's job for two weeks needs the approved fire damper submittal before the inspector arrives at 10:00. The project drive has folders called "Submittals", "Subs", "Approved" and "Mech", and the file he needs is named scan0042.pdf. He finds it at 10:40, after the inspector has left.
Use the same numbered folders and one naming rule on every job, write both on one page, and create the folders before the first document arrives. Name each numbered document by job, type and number, revision and date, and keep it in one place. Files get lost when each person invents a folder and a name as a document lands. A university research-data guide adds two details: numbers with leading zeros and dates written year first keep files in order when sorted by name, and names should avoid spaces and symbols.
Set it up once, for every job
- Use the same numbered top-level folders on every job: 01 Contract, 02 Drawings, 03 Specifications and addenda, 04 RFIs, 05 Submittals, 06 Changes, 07 Correspondence, 08 Meetings, 09 Schedule, 10 Quality, 11 Safety, 12 Photos, 13 Closeout.
- Split drawings into current and superseded, by discipline, so the current folder holds one revision of each sheet.
- File submittals by specification section, such as 08 11 13 for hollow metal doors and frames.
- Name numbered documents by job, type and number, revision if any, date and a short subject if it helps: 3186_RFI-009_2026-02-17_frame-anchors.pdf, with leading zeros and year-month-day dates.
- Start other documents with the date after the job number: 3186_2026-02-17_MIN_site-meeting-06.pdf.
- Keep one copy in one place, and never put "final", "new" or "(2)" in a name.
- Write the rules on one page in the top folder, and check new files against it weekly for the first month.
Folders and names are one part of the system; the registers and who keeps them are in setting up document control. Photos follow their own rule: see organizing construction photos.
Common mistakes
- Letting each person create folders as documents arrive.
- Names like "FINAL-2" or "revised", which say nothing about the revision.
- Copying one file into three folders, so nobody knows which copy is current.
- Changing the structure mid-job without saying where the old files went.
Action list
This week
- Write your folder list and naming rule on one page
- Save an empty folder set to copy for each new job
- Split the current job's drawings into current and superseded
- Rename open RFIs and live submittals to the rule
- Show the page to everyone who files documents
Check your understanding
You take over a job with 2,000 badly named files. Do you rename them all?
