Every policy, subcontract, and safety plan your company owns — answerable in plain English, cited to the exact document, section, and page. Built for the field. Zero hallucination. Real receipts.
Point Plumb at your documents. Your crew asks in plain English. You get answers cited to the page. That’s the whole loop.
Safety plans, subcontracts, procedures, policy manuals — ingested with section and page anchors preserved. Live in under 10 minutes.
“What’s the LOTO procedure on the Taylor job?” “Am I covered if I leave the scaffold for 15 minutes?” No training, no query syntax.
If confidence is low, Plumb refuses and flags it as a Knowledge Gap — never guesses.
Every answer carries a confidence score. Below threshold, Plumb doesn’t paraphrase — it surfaces a Knowledge Gap and tells your safety director what your documents don’t cover yet. This is not a best-effort disclaimer. It’s a gate in the code.
Plumb scopes answers by role — the apprentice doesn’t see contract pricing; the controller doesn’t get PPE specs. Same documents, different authorized views.
Plumb logs every question it couldn’t answer and every policy that’s getting stale. That’s a map of the gaps in your written plan. Update the doc, Plumb re-indexes.
Safety directors spend 40%+ of their time answering questions already in your documents. At 3 safety directors across 2 regions, that’s $132K/year of time Plumb gives back — before you count supers, PMs, and field workers.
OSHA inspection next month? A worker claims nobody told him about the fall protection change? Plumb keeps a timestamped record of every question, every citation served, every refusal — scoped to your tenant, exportable on demand.
I’m Antuan — assistant superintendent, still in the field. I’ve run MEP closeouts on a $500M Amazon distribution center, commissioned HVAC systems at the Tesla Battery Plant, spent a year on the roof at Samsung Semiconductor, and I’m currently building a Sam’s Club in Houston. Five years. Every trade.
The moment I decided to build Plumb wasn’t dramatic. It was the daily grind at my current company — calling the super, then QC, then safety, then the PM — for information that was either never covered in orientation or buried somewhere in documents nobody could pull up from the field. It happens on every project, at every company, regardless of size.
And it was never just safety questions. It was scope questions — what exactly does this sub have in contract? Policy questions — what’s our standard for this work? Document questions — where is that drawing? Any question you can’t immediately answer in front of a subcontractor feels like a failure. That feeling is universal across every title in a GC. I built Plumb to kill it.
Every answer cites the exact document, section, and page — because in construction, “I think it’s in here somewhere” isn’t good enough.
MVP is the foundation. These three extend it. Every Founding Partner has the early-access commitments below in writing.
One daily, OSHA-audit-defensible safety policy per worker — sourced from your company’s own documents, selected for their role, delivered before the first tool is picked up.
Attributed verbal knowledge queryable alongside documents. “What did we decide about the concrete pour?” — answered with who said it, when, and in which meeting.
Structured in-meeting statement capture → Review & Formalize → queryable from minute zero. Additive to Procore, not a replacement.
Plumb isn’t a wrapper around a public chatbot. It’s a purpose-built retrieval system with hard constraints — the kind your lawyer and your auditor can both sign off on.
Your policy manuals, subcontracts, and procedures stay in your tenant. Not Anthropic’s training set. Not Google’s. Contractually guaranteed in DPA §3 — available on request.
Every query is scoped to your workspace. We run automated isolation tests on every deploy — zero cross-tenant leaks, proven.

Enterprise-grade security controls are on the roadmap for Q3 2026. We’ll publish the bridge letter as soon as it’s available. DPA available on request.
Founding Partners get: launch-week onboarding with me personally, a locked-in Founding Partner rate, and direct line to the build. In exchange: you commit to 30 days of active use and honest feedback. We’re selecting 3 GCs.
