Compare the accepted baseline against the current programme, find where it has grown in time, scope or cost, attribute each flag to a cause in your own words, and draft NEC Early Warning Notices and Compensation Event notifications from your attribution, 100% in your browser, nothing uploaded.
🟠 Early Warning Notice, proactive
You notify a matter that could affect price, Completion or performance, as soon as either party becomes aware of it. Forward-looking.
🔴 Compensation Event, after the fact
A defined event has occurred; notification and quotation follow the contract's clauses and time bars. Past-tense, factual.
Often the right answer is an EWN now and a CE when the effect crystallises, you can draft both from one portion.
🔒 This is commercially sensitive claims material, it is parsed and drafted entirely in your browser. No server, no upload, no storage.
This tool drafts content for your commercial process from programme evidence. It does not administer the contract and is not legal advice. Notice validity depends on your contract's forms, addresses and time limits, and any cost shown is planning data, not a priced quotation.

Early Warning Notices and Compensation Events, from the programme
Under NEC contracts, an Early Warning Notice (EWN) flags a matter that could increase cost, delay Completion or impair performance — raised early so both parties can head it off together. A Compensation Event (CE) is a defined event that entitles the Contractor to an assessed change to the Prices and/or the Completion Date. Both live or die on programme evidence.
Why the programme is the evidence
Comparing the accepted baseline against the current programme shows where the works have grown in time, scope or cost, and where the critical path has moved. That attribution is what turns a general complaint into a specific, defensible notice. This tool reads that growth from your P6 files, structures it, and drafts the EWN and CE notifications from your attribution.
What it does, and does not, do
It detects and structures programme change and drafts the notices.
It never decides what is claimable — entitlement and assessment remain your professional and contractual judgement.
Costs read from a programme are planning data, not a priced quotation.
Everything runs in your browser; nothing is uploaded.
Does this tool decide whether I have a claim?
No. It detects programme change, organises the evidence and drafts the paperwork. Whether an event is a Compensation Event, and how it should be assessed, is a matter of the contract and professional judgement — not something the tool determines.
What is the difference between an Early Warning and a Compensation Event?
An Early Warning is a forward-looking risk notice; it can precede, but does not by itself create, an entitlement. A Compensation Event is the defined event under the contract that actually changes the Prices and/or Completion Date once notified and assessed.
