A building gets built twice: once on site and once on paper. Every question the superintendent cannot answer becomes an RFI, every product swap becomes a submittal, every surprise behind the drywall becomes a change order with a price and a fight attached, and every day ends with a log of who was on site and what got done. A mid-size contractor writes thousands of these a year, each tied to a drawing, a date and an outcome.
That paper trail is a record of construction judgment, and it is the kind of record AI buyers describe. Polyshares names construction and has published a general contractor license. Nyne buys estimates, invoices, jobs and dispatch. Two broker ads seen on 2026-10-14 name Procore and Buildertrend outright.
This hub is for owners and operations leads at general contractors, homebuilders and remodelers with ten or more people in the office and the field. It shows which project records buyers ask about, what is usually the owner's or architect's rather than yours, which buyers take a company your size, and the questions to raise before any job file leaves your server. Sub-pages go deeper on commercial GCs and on residential builders and remodelers.

Who wants this
Do buyers want general contractors, builders and remodelers?
No buyer publishes prices by industry, but their own intake forms show which industries they rate higher.
- Troveo puts construction and trades in its second of four demand tiers: "Your industry carries above-average buyer demand."30
- Polyshares takes construction and specialty trades, without marking it premium.31
- VMS, a broker, gives construction standard weight when it estimates value.32

What buyers value
What in a contractor's records buyers value
What buyers look for in your records, and what to talk through with your buyer before anything leaves your systems.
| Data | Where it lives | Why a buyer values it | Raise with the buyer |
|---|---|---|---|
| RFI logs and responses | Procore, Autodesk Construction Cloud or email | A question, the drawing it points at, the designer's answer and the days it took: field problem solving with an outcome attached. | Architect and engineer names, and whether the design team considers its responses its own work. |
| Change orders and change order logs | Procore, Buildertrend, Excel | How scope changes get priced, argued and approved, step by step, with the money visible. | Owner names and contract values on each change. |
| Submittal packages and review comments | Procore or a shared drive | Product data matched to a spec section, then returned approved, revised or rejected with reasons. | Manufacturer cut sheets that are third-party copyrighted material. |
| Daily logs and site reports | Procore, Buildertrend, Raken | Weather, crews, deliveries and delays written down every working day, the raw timeline of a project. | Worker names and any injury reports. |
| Bids, estimates and buyout sheets | Excel, estimating software, email | How a contractor turns drawings into a number and then chooses subs to hit it. | Subcontractor pricing shared with you in confidence. |
| Project manager and superintendent email | Outlook or Gmail | Coordination across owner, architect and a dozen trades, where most schedule decisions are actually made. | Owner and tenant details on private and government jobs. |

- Buildertrend dataBuildertrend's terms grant it a perpetual license to Customer Data that includes the right to sell and sublicense it, and a broker already names Buildertrend in ads to builders.

Selling or closing
Selling or closing your contractor? License its data first
Contracting firms are sold to key employees, merged into larger GCs or wound down when the founder retires, and the job files usually sit on a server nobody opens. Polyshares describes its published deals, the general contractor license among them, as perpetual and exclusive. If a sale is coming, ask each licensing company whether an exclusive license would follow the business to its new owner, and whether you can license completed jobs before closing.3,1
FAQ
Construction contractors: questions, answered
ENR reported that Procore cut Trunk Tools off from its API, citing the security of customers' data, as construction platforms compete over data to train AI agents. Your project records have value to more than one party, which is worth knowing before anyone asks you to connect an account.50
Less than you might think. Cost estimators score 100 out of 100 on O*NET's email scale and construction managers 98, and those are the people who write the RFIs, estimates and change orders. Count your office and project management staff when you size the archive.6
The one published construction figure is Polyshares' $300,000 general contractor license, its own claim with no size or data volume given. Wider published ranges mostly run $100K to $2M, also as the buyers' own claims: micro1 states $100K-$2M+, Cognor Labs and Ventra $100K-$2M. Years of linked RFIs, change orders and cost data are what move a contractor up that range.1,8,55,56
You can offer that. SOPs, playbooks and templates top micro1's list, and a package of your own procedures leaves owner and design-team documents out. Say so on the first call so the offer is priced for what you are actually including.11
