A retrieval engine that sits beside the existing system, reads what it already produces, and closes knowledge capture. Aimed at construction estimators, unbundling the one module people actually use.
In short: Construction Knowledge Base is a retrieval engine aimed at construction estimators, covering knowledge capture. It scores 70/100 on AltF Ideas, carried by moat (95) and held back by feasibility (27). Typical pricing is $5.4k–$81k per customer per year, with a first version reachable in six to twelve months for $35k–$98k.
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 cost is invisible on any P&L line, which is why it never gets fixed.
A retrieval engine that handles knowledge capture end to end and hands a human the exceptions rather than the queue. 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 |
|---|---|
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| An internal hire | Works until volume doubles, then breaks again |
| A spreadsheet | The real incumbent in most of the market, and it is free |
The incumbent is a person, and displacing a person is a change-management problem.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
