A narrow retrieval engine scoped to knowledge capture alone — no platform, no migration, no six-month rollout. Aimed at construction project managers, writing down what only one person knows.
In short: Construction Knowledge Base on Retrieval is a retrieval engine aimed at construction project managers, covering knowledge capture. It scores 73/100 on AltF Ideas, carried by moat (93) and held back by feasibility (28). Typical pricing is $4.1k–$62k per customer per year, with a first version reachable in six to twelve months for $36k–$107k.
Construction teams lose twenty years of know-how walking out at retirement. The work sits between two systems that were never designed to talk. The error rate is tolerated because measuring it would cost more than the errors.
Knowledge capture handled by a retrieval engine, with a human signing rather than writing. Revenue is data subscription, which suits a buyer who wants the cost to track the value rather than the seat count.

Retrieval over private documents became cheap enough to run per query. Construction is growing at roughly 20% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| An internal hire | Works until volume doubles, then breaks again |
| A generalist AI tool | No domain grounding, so output needs full human review |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
Integrations with the incumbent system of record are undocumented and gatekept.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
Score problem urgency, willingness to pay, and reachable audience size before writing any code.
→ AltF IdeaLabAsk how they handle this today and what it costs them. If nobody can quantify the pain, the demand score is optimistic.
→ Survey BuilderCheck availability, DNS, and email authentication in one pass so your first outreach lands in an inbox.
→ AltF DomainOpsStand up intake, the review queue, and billing before you build the clever part.
