Mining runs on operational truth — plods, diaries, dispatch, daily reports. Hevi turns that truth into contractual action: notices served, claims evidenced, invoices verified, value protected. For owners and contractors. Sometimes on the same project.
Standby and ratchet captured. Every stood-down hour priced from the schedule of rates the day it's recorded.
Notices served inside the window. Production relief, latent conditions, delay events — drafted from your own plods and diaries, cited to the clause.
KPI adjustments contested with evidence. When development metres miss the rolling target, you know whether it's yours to wear — and can prove it either way.
→ The margin you earned underground stops leaking above it.
Underground & open cut
Operational truth, made contractual.

One day · one contract
Twenty-four hours on a mining contract, watched properly.
This is a normal day. Nothing dramatic happens. Watch how much of it is commercial — and how much of it your current process would never see.

The leak register
Where mining contracts actually lose money
Not in court. In the day-to-day: 5–10% of contract revenue at risk or missed, one unremarkable event at a time.
01Missed noticesThe window closes silently. The entitlement dies with it.
02Unclaimed standbyStood-down hours logged in the diary, never priced, never claimed.
03Scope drift“While you're in there...” — months of unpaid work on a nod.
04Instruction ambiguityDirections in emails that nobody converts into variations.
05Weak records$10m claims settle for $5m because the evidence can't be assembled.
06Invoice leakageRates, ratchets and reliefs paid wrong in both directions — nobody checks against the contract.
07KPI disputesProduction adjustments worn without checking whether relief applied.
08Knowledge walking outThe one person who knew the contract takes it with them on their last swing.
The data already exists
Your site records everything. Nothing reads the contract.
Mining is the most instrumented industry on earth — fleet, dispatch, shift records, planning, ERP. Hevi sits above that operational layer and interprets it commercially: event → obligation → action → evidence.

Hevi wasn't built by a tech company that discovered mining. It was built by mining people who got tired of watching value leak.
