The AI assistant can make mistakes

Why the assistant can make mistakes

An AI model does not reason like a cost estimator: it produces the answer that seems most plausible from what it has learned and what you give it. So it can:

• make up information with confidence: a price, a reference to a standard or building code, a specification clause that does not exist;
• misread a document: a scanned drawing, a complex table, an illegible dimension, a missing page;
• get a calculation wrong: a quantity, an area, a total or the tax;
• miss the real conditions on site: the existing building, access constraints, the prices charged in your area;
• rely on outdated knowledge: its price and regulation references have a cutoff date.

What to check

Before you share an estimate, export a bid form or send out a bid invitation, review in particular:

• unit prices, quantities and units;
• totals, fees and tax rates;
• the standards and regulations it cites;
• the trade packages, specifications and locations the assistant created or changed in your project;
• any text meant for the owner or for the subcontractors you invite to bid.

The assistant acts in your project with your permissions. You remain responsible for the documents and figures you send.

Getting more reliable answers

• Give context: type of work, floor area, level of finish, known constraints.
• Say exactly what you mean by mentioning a trade package, a specification or a document with "@".
• On a long PDF, name the relevant pages instead of letting the assistant go through the whole document.
• Ask it to explain where a figure comes from, then check it against your own references.
• If an answer looks wrong, tell it so and rephrase your request.
