The contractor was instructed to relocate air handling unit AHU-01 from the roof plant deck to the ground-floor plant room.
The problem
The answer is in the documents. Finding it takes days.
The facts are usually there — buried across thousands of records: programmes, reports, emails, site diaries and minutes. Finding them means hours of reading, cross-checking and searching.
You already know how to investigate a claim. CDIA gives you the hours back.
What CDIA does
One path from the records to a defensible answer.
CDIA prepares the records, reports and contract once, on your computer. Then every answer, analysis and draft follows the same visible path.
Ask, then review the evidence first
Ask in plain English. CDIA gathers the relevant records, report extracts and contract clauses and pauses so you can untick anything before the answer is written.

A cited answer that opens the source
Factual statements carry citations. Click one and the document opens beside the answer, at the page where CDIA holds it, even a scanned one.

Advice: labelled analysis, never mixed into the facts
Ask for analysis over the same reviewed evidence: what the records show, competing interpretations, weaknesses, and what to investigate next.

Draft: cited sections, exported to Word
Factual background, chronology narratives, briefing notes and responses, cited to the reviewed evidence, exported with a line stating which AI produced them.

Also Chronology Builder, Evidence Listing, Report Q&A, Contract Search and Activity Investigation, all working from the same prepared evidence.
See it work
Watch it find an answer, and show you where it came from.

Why professionals use it
Private by choice. Traceable by design.
Built for work that will be challenged.
The differentiator
Your evidence, your boundary
Documents are stored and prepared on your computer. You choose the evidence CDIA may use, and the answer says what it used.
Cloud AI or Private AI
Run the AI through your own provider key, or entirely on your machine. Switch at any time.
Check every answer
CDIA issues and checks citations; each opens the source, at the page where CDIA holds one.
Records, reports, contract kept distinct
A claim is never quietly presented as a fact.
Where CDIA fits alongside general AI tools
General AI tools are extraordinarily capable, and many professionals use them every day. CDIA is not a replacement for them. It is the construction evidence workflow built around the AI: a prepared project that persists for as long as the matter runs, an evidence boundary you draw, the review before any answer, records, reports and contract wording kept distinct, and citations that CDIA issues and checks, opening the source where held.
What general AI tools do well
Reasoning, summarising and drafting over whatever you give them
Fast, flexible and improving constantly
Excellent for polishing prose and thinking aloud
What CDIA adds around the AI
A prepared project that persists for the life of the matter
An evidence boundary you draw, and a review before any answer
Records, reports and contract wording kept distinct
Citations CDIA issues and checks, opening the source where held
Cloud AI on your own key, or Private AI on your machine
Already using a general AI tool? Keep using it to polish prose. Use CDIA for the part you will be cross-examined on.
