A general contractor finishes a job and archives it. The drawings go to the owner, the retainage gets released, and the project file sits in Procore or on a shared drive for the statute of limitations to run out. For an AI training-data buyer, that archive is the interesting part: hundreds of real questions, decisions and cost changes, each with a date and a role attached.
This post works through which records buyers want, which they do not, and how a firm might scope a first license. The aim is to help you sell construction data knowing what is actually in demand.
Why buyers want operational records
AI companies are training models to do multi-step professional work: read a document, ask the right question, track a change through to its cost. Public text on the web shows the finished product of that work. It rarely shows the working.
A construction project file is the working. An RFI log records a field problem, the question someone wrote, the answer a design professional gave and how many days it took. A change order then prices the answer. The schedule shows what slipped. Put together, those records describe a decision chain that a model cannot learn from a textbook.
That is why buyers describe their interest in terms like “operations records”, “documents and files with metadata” and “project and service records” rather than naming industries.
The records, ranked by usefulness
The ranking below is our reading of what makes a record useful to a model: it pairs a situation with a response, carries dates, and links to other records. It is not a buyer’s published ranking.
| Rank | Record | Why it helps | Common catch |
|---|---|---|---|
| 1 | RFIs with responses | A real question paired with an expert answer and a time to answer | The answer may be the designer’s work |
| 2 | Change orders | Scope change, priced lines and the approval chain | Owner names and signatures |
| 3 | Schedules with revisions | Planned against actual, with reasons for each change | Activity names that name clients |
| 4 | Daily logs | Crew counts, weather, delays and work in place, day by day | Worker names and site address |
| 5 | Estimates and bid results | Quantities, unit costs and whether the bid won | Bid confidentiality terms |
| 6 | Submittal logs | Review cycles and rejection reasons | Manufacturer literature is not yours |
| 7 | SOPs and QA checklists | How your firm runs work, written down | Usually clean; often short |
Why RFIs come first
An RFI is close to a ready-made training example. It has a context (the drawing reference and the field condition), a question written by a professional, and an answer written by another. A firm that closes 40 projects a year with 50 RFIs each holds 2,000 of these a year.
Why linked records matter more than volume
A thousand daily logs on their own say what happened on site. The same logs linked to the RFI that stopped work, the change order that priced the fix and the schedule activity that moved say why. Keeping one project identifier across systems, even after you replace client names with tokens, preserves that link.
What a buyer lists in its own words
Construction appears nowhere on the buyer pages at our November 7 check. Their listed categories still cover most of a contractor’s file:
| Buyer | Categories close to construction records |
|---|---|
| micro1 | Operations records, process documentation, SOPs, accounting records |
| Scale AI | Documents and files with metadata, structured records, ERP records, calendar events |
| Nyne | Accounting records including estimates and invoices; jobs and calendars; project and service records |
Should a contractor we introduced sign with micro1, Scale AI or Nyne, that buyer may owe this site a referral fee; the table above was written without regard to it. The buyers reference has the full published terms.
What to leave out
Some records in a project file are not yours to license, and some carry too much personal information to be worth cleaning:
- Drawings, specifications and models: these are the design team’s work.
- Manufacturer data sheets inside submittals.
- Certified payroll and timesheets with names.
- Pay applications and lien waivers with bank details.
- Incident reports that name people.
- Any project where the owner contract claims all project records or keeps them confidential.
The ownership reference covers how to read those contract clauses.
How to scope a first license
Firms that have looked at this usually start narrow:
- Pick one system and a run of years where it was used consistently.
- Choose two or three record types, often RFIs, change orders and daily logs.
- Drop projects with restrictive owner contracts, public work and anything still in dispute.
- Replace client, site and worker identifiers with tokens before anything leaves.
- Check headcount and years in business against each buyer’s published floor.
A narrow first scope is easier to clean, easier for your lawyer to review, and easier for a buyer to assess.
The records worth the most are the ones your project managers already complain about writing: the RFI they chased for three weeks is exactly the example a model has never seen.
