This is the work CDIA was built from. A claim arrives, or has to be prepared, and the answer is somewhere in three thousand documents.
“What extension of time did the contractor claim and what did the contract administrator grant, and why?” CDIA gathers the claim, the assessment, the notices, the minutes and both expert reports, shows the evidence in the Investigation Review, and on Continue gives you a cited account: on the example project, the weeks claimed and the weeks granted, the events the assessment relied on, the contractor’s disagreement recorded in the minutes, the contract clause as wording, and the two expert reports that disagree, labelled as opinion. Reports and claims in the project are labelled as the author’s account; check each statement against its cited source. If the records are silent on cause, the answer says so.
“What notices did the contractor give, and what does the contract require?” Limit the source selection to correspondence and contract if you want the notice trail on its own. The answer cites each notice and presents the contract requirement as the wording of the terms. The scope note tells you what was and was not considered.
“What does the contractor’s claim say about the October weather, and what do the records say?” Name the document and CDIA reads it in depth, answering with citations to the claim and, where it holds them, the page. Where several documents could match, it asks which you mean. Then ask the records question in the same investigation, and you have the assertion and the contemporaneous evidence side by side, each cited. That is the shape of a response.
Open Advice: “Advise me on the commercial issues I should prioritise.” The analysis is labelled, cited, role-neutral, and reasoned from the reviewed evidence: strengths, weaknesses, competing interpretations, what to investigate next. It does not advocate.
Open Draft: “Draft a factual background section on the east car park access restriction from the selected evidence.” The draft cites the reviewed evidence, and CDIA checks the citation references before showing it. Export to Word with the AI provenance line, and start your review from a document with source citations you can check.
Scanned PDF letters and instructions are read automatically through the built-in OCR and cited to their page. If a scan cannot be read, the Project Ready summary names it, so you know what could not be read.
CDIA does not determine entitlement or quantum. It finds the evidence, keeps the claim distinct from the record, and shows you where everything came from.
