Knowledge base for timber construction and joinery when someone asks which decor was fitted last time.

If it’s on file, you can ask for it. As a manufacturer, the Construction Products Regulation requires you to keep the declaration of performance and the technical documentation for ten years after placing the product on the market – and that is exactly when the request tends to come, when the house is sold or renovated, often from an expert with a deadline looming. You ask by property or job number; the answer gives the document with its source, plus the test certificate it is based on, if that is in the knowledge base. If the system finds no declaration for the job, it tells you so – and you know where you stand before you reply.

The slip goes in as it is, abbreviations and all. In the first weeks after go-live, try a few real slips to see how well the handwriting is read. The system can’t know on its own what the abbreviations mean in your company; add the key once as a separate note, and it can come up as a second source. The answer cites the slip itself, so the painter reads the original rather than relying on a paraphrase. And because a build-up you’ve refined over years should stay with you: your own instance on servers in Germany, the language model in an EU data centre, and no model is trained on your data.

We look at a sample file to see whether anything useful can be read from a BTL or machine file; you should expect the joint geometry not to appear in the answer. What you can ask about is the assignment: which file belongs to which job, which component and which drawing revision, and when it was last changed. Whether that comes through clearly from your file names and folders is worth checking in the first weeks after go-live. For the values themselves, go via the workshop drawing and parts list stored alongside. The answer gives the file path, so the version that goes to the machine is the one that really contains the handwritten change from the measuring appointment – not the one that happened to be saved last.

The usual items are care and maintenance instructions, the evidence for the products installed and the handover record with outstanding points; which of these is actually owed is set out in the contract and the bill of quantities. The system can pull together what exists for the property and say what it can’t find – often the more useful part of the answer, because by handover day it’s too late to get hold of it. Nothing is sent on its own: you get a draft as a Word file, PDF or email draft, go through it and send it yourself.
