Human-in-the-loop means software does the preparation and a person makes the decision. An AI agent might draft a change order, code an invoice or flag a variance, but nothing posts to the ledger, goes to an owner or pays a vendor until someone with authority approves it. The person can accept, edit or reject, and that decision is recorded.
Why it matters
AI models can be confidently wrong. In construction finance and contracts, mistakes cost real money and relationships. Keeping a human in the loop gets the speed of automation while keeping accountability where it belongs, with the PM, controller or project executive. Each correction also shows where the automation needs work.
Worked example
Illustrative: after RFI-212 confirms the missing fire dampers, an agent drafts CO #14 at $86,400 from the sub quotes and markup terms. The PM sees the draft, adjusts one line item, and approves. Only then does it update the budget and get queued for Pay App #9. The audit trail shows “drafted by agent, edited and approved by PM.”
Common mistakes
- Making the review so tedious that people rubber-stamp it.
- Requiring approval on everything, including low-risk lookups, so it never saves time.
- Not recording who approved what, defeating the purpose.
How os.construction handles it
Human approval is a core rule in what we’re building: agents propose, people approve, and both are recorded. We’re tuning where approvals sit with founding contractors.
