CONTRIX reads the contract clause by clause, checks it against the Construction Act and the standard form (NEC4 ECC, JCT 2016/2024, FIDIC), puts every notice period in a diary and builds the claim file the way the contract's own procedure demands. It never says "you are entitled" — it shows where a file can be opened, on what basis and by when.
Recorded from real screens on an NEC4 ECC Option A substation subcontract: dashboard, analysis, claim radar, automatic mail scanning, e-mail to claim record, man-hours, today, NEC4 report, letter draft and portfolio. No sound — use the chapter buttons.
Real screens from a demo portfolio (NEC4 ECC substation, JCT D&B fit-out, FIDIC Red Book, VOB/B). Click to enlarge.
Upload a PDF, Word or scanned document. The rest is deterministic: same document, same rule set, same result — and every finding is tied to a page and a quote.
Clause parsing, OCR, Contract DNA: the Prices, completion date, delay damages and cap, retention, final date for payment, notice periods, governing law — each with source and page.
The country pack loads: mandatory law (HGCRA, Scheme, UCTA), deviations from the standard form (NEC Z clauses, JCT Schedule of Amendments, FIDIC Particular Conditions), your playbook. Risk score and deviation index follow.
Access dates, payment due dates, pay less notices, early warnings, defects periods, bond expiries — every window lands in the calendar; conditions precedent are flagged. E-mails and Outlook feed events automatically.
The claim radar shows the opportunity, the protocol timeline sequences the steps (notification → quotation → PM's reply → adjudication), evidence readiness is measured; letters and the claim dossier come out as Word.
From pre-signature review to the final account: every module works on the same contract record, the same event chain and the same audit trail.
Every clause passes through the jurisdiction's rule set; findings are listed by severity with page and quote. The score follows a saturation curve — not every contract ends at 100. The rule-set fingerprint is stored with the analysis, so years later you still know which rule text produced a finding.
Access dates, interim valuation dates, due dates, pay less notice deadlines, final dates for payment, rectification periods, bond expiries, termination notices — all in the calendar; day counting per jurisdiction (calendar · working days · Werktage). A missed notice becomes a finding.
49 heads: extension of time, prolongation, disruption, variations, fluctuations, interest, retention, defects, defence heads. Basis + trigger + timing score, protocol timeline, evidence readiness percentage.
Early warning, CE notification and quotation, JCT notice of delay, loss and expense, application for payment, pay less notice, notice to suspend, notice of adjudication — plus Dutch, German and Turkish sets. Word drafts pre-filled from the contract; nothing that is not in the contract is written.
NEC Z clauses, JCT Schedule of Amendments, FIDIC Particular Conditions, UAV / VOB deviations; Risk Deviation Index 0-100; statutory conflicts carry the rule id.
Pick clauses from the UK library (HGCRA-compliant payment and adjudication, CDM, BSA, CIS/VAT, UCTA limits), attach the bill and crew plan, get the Word package with 13 annexes. The draft leaves clean against its own rule set.
Compares MS Project / Primavera programmes: slippage, float, critical path, concurrency; delay damages exposure; staffing commitment vs. allocation sheets.
Outlook / IMAP mail is classified by intent, matched to the contract and turned into an event + notice + claim record with one approval. Outlook and Word task panes.
Claimed and agreed amounts per counterparty, closing windows, expiring bonds, pending mail. The executive brief is ready every morning as a Word report with native charts; lien & bond calendar, guarantee tracking and flow-down checks on the same screen.
No data entry. The product produces its own records from e-mails, attachments and bills of quantities; every proposal is applied with one approval and every step is written to the audit trail.
Connect an Outlook / Microsoft 365 or IMAP account; the in-server poller reads new mail every 60 seconds. 19 intent classes (claim, extension of time, variation, payment application, notice, NOD, minutes, drawing…), reference / amount / days / deadline extraction, contract matching with reasons. Irrelevant mail is not stored; bodies are never kept.
A contract attached to an e-mail is detected, analysed with its country and role, and the project and counterparty company are created; pending mail is re-matched to the new contract. Project candidates are discovered from subject lines and companies from sender domains — the portfolio fills the day the account is connected.
Bill items are converted to man-hours with labour norms (civil, mechanical, electrical — norm-referenced); the scope is understood from the works description; divided by the period, an average and peak crew is proposed per role. The "12 steel fixers" commitment in Z4 is read automatically and compared with the monthly allocation sheets; short days and deduction exposure are computed.
The main contract and the subcontract are read side by side: claim notice periods, final dates for payment, delay damages, limitation of liability, dispute forum. The difference stays with the main contractor — gaps, aligned and unmatched clauses are listed with clause and page. In an addendum or a new revision every changed clause is classified and the affected areas are shown.
Executive brief (native Word charts), contract package (agreement + 13 annexes), letter drafts, claim dossier, Excel exports. These are real output pages.
Also: Excel (today, claim radar, review queue, bill template) · Markdown / JSON for every report · Outlook and Word add-in manifests.
Choosing a country is not one setting: language, currency, day counting, sectors, contract families and the rule set to load change together. A UK analysis never reads a German rule.

Most claims are not lost on a late notice but on the steps after it: the quotation period, the PM's reply, the update, what silence means. CONTRIX knows the chain for every jurisdiction and form and lays it on a calendar.
CONTRIX is deterministic: the document is not sent to any large language model, and every rule that produces a finding is a readable file. Single-file install or on your own server.

UK GDPR: the uploaded contract is parsed and profiled, the file is not kept; only a signed copy is stored if you ask for it.
Every decision, finding change and export is written append-only with actor, time and reason.
Rule content hash and version are stored with the analysis; a finding shows years later which text produced it. The legal review pack is part of the product.
