The CWMF variation lifecycle, governed clause by clause.
Post-award is where public works projects lose cost certainty. GovIQ tracks every variation from anticipated forecast to ER determination, runs the statutory threshold tests, and stops a 50% ceiling breach before it reaches OGP Legal.
From anticipated to determined — every state mapped to CWMF mechanics.
Anticipated
Forecast, no PI issued
PI Issued
Proposed Instruction sent
Quoted / Evaluated
Contractor quote, DT valued
ER Determined
Determination issued — locked
Clause references tagged on every variation: 10.3 contractor claim · 10.4 ER proposed instruction · 10.5 ER determination · 10.6 compensation event.
T1–T7: the variation tests that keep an award defensible.
Every variation runs against the three-state model — Determined, Forecast and Anticipated Final Cost. Each test consumes a specific state, so a forecast warning never gets confused with a binding breach.
| Test | Trigger | Action on breach |
|---|---|---|
| T1 — single variation > 5% contract sum | Determined | Require AND approval |
| T2 — cumulative > 10% | Determined | Require AND approval |
| T3 — cumulative > 15% (EU de minimis) | Determined | AND + Legal + C&E joint review |
| T4 — cumulative > 50% (statutory ceiling) | Determined | Hard block — OGP Legal route to override |
| T5 — AFC > approved capital budget | AFC | Capital re-approval at original threshold |
| T6 — AFC crosses capital band | AFC | Capital re-approval at the new threshold |
| T7 — variation crosses OGP band | Determined | Re-procurement risk warning |
A live Proximity Engine warns as a draft value is typed — Green under 80% of the nearest threshold, through to Red as it approaches the statutory ceiling.

Employer's claims & EOTs
Extension-of-time applications and employer's claims with the 20-day response clock and escalation built in.
Monthly cost reports
Immutable snapshots generated to the CWMF / healthcare template — Cover, Dashboard, App A–D, cashflow — never edited in place.
Three-state rollups
Determined, anticipated and forecast cumulative totals recomputed on every status change. They are not the same number.
Risk register
Contract risk tracked alongside the variation pipeline so anticipated cost is never a surprise.
Works programme
Programme and practical-completion targets tracked against actuals.
Contractor external access
A fair, transparent, scoped view for the contractor — submissions and certificates, audit-stamped.
