Built for bulk earthworks in the resources sector

Progress claims your client can't argue with.

QPC Control puts the contractor and the client on the same live claim — every quantity linked to the survey that proves it, every variation and day-work docket in one place, and a certified payment figure both sides can stand behind. No more reconciling spreadsheets by email.

Built by a registered surveyor with 20 years on major infrastructure and resources earthworks projects — who has worked both sides of the progress claim, and knew exactly what needed fixing.

Project summary

Fewer disputes— evidence stays linked to the line it supports, permanently

Faster assessment— claims read from one live BOQ, not a rebuilt spreadsheet

Certify with confidence— every figure backed by survey, timestamped and attributable

Get paid sooner— the statutory clock is visible and enforced

The claim every month

A BOQ with hundreds of line items, and a month-end deadline

On a bulk earthworks contract the contractor claims progress roughly every month. The assessor checks every line. Both keep their own version. The gaps between them turn into queries, disputes, and late payments.

TodayClaiming in Excel

Contractor's sheet and assessor's sheet drift apart — nobody trusts the totals.
Variations agreed over email never make it back into the live BOQ.
Survey volumes, dockets and photos live in folders nobody can find at adjudication.
Statutory payment dates are tracked in someone's head — until one is missed.

With QPCOne shared source of truth

Contractor claims and assessor certifies against the same BOQ line, live.
Agreed variations fold straight into the BOQ and the contract value.
Survey packages, dockets and evidence attach to the exact claim they justify.
Every claim has a tracked statutory clock and a full, timestamped audit trail.

Indisputable linkage

Every quantity change, variation and approval decision is timestamped and attached to the specific BOQ item — so the record can't be argued away.

Tamper-evident history

Claim history isn't a static spreadsheet. It's a live, versioned record from Claim 1 to project completion, with every variation captured the moment it was agreed.

An audit trail, not a paper trail

Centralising evidence turns an opaque paper trail into a transparent record — a practical insurance policy for both parties against future disputes.

This doesn't remove the underlying commercial negotiation — parties will still disagree about entitlement, rates and risk allocation. What changes is that when they disagree, both sides are arguing from the same record of what was measured, when, by whom, and with what evidence — instead of spending months establishing that record for the first time.

The solution

One shared, auditable workspace

The whole commercial workflow of a bulk earthworks contract, between exactly two parties — not a calculator bolted onto a spreadsheet.

Q · Quantities

Measured, not guessed

Every line is claimed against the bill of quantities, with survey evidence attached where required. The BOQ is the heart of the system — every other part links back to it.

P · Progress

Visible to both sides

Cumulative progress, variations and day works roll into one live picture, reconciled to the design quantity for every claim period.

C · Claims

Certified & signed

Submit, assess line by line, and issue a signed payment certificate — immutable and re-downloadable forever.

The bill of quantities

One source of truth, from claim to claim

Sectioned line items, units, rates and cost codes live in one place — claims read from it, variations write back to it.

Cumulative built in — last period, this period and remaining on every line, so the claim writes itself from the schedule.

One-click PDF or CSV export, ready to import into your financial and project-management tools.

Every change, claim and query is stored as a permanent record against each line item in the BOQ.

Bill of Quantities

Every line, its whole life

Full history, stored against the line item — not a spreadsheet

Progress, versioning, variations and queries all live on the record for that one BOQ line — not scattered across emails and revised spreadsheets.

Item 2.2 — full claim history

QPC Control line item detail — full claim history, variations and BOQ adjustments for one line

One line item, its whole life — design quantity, every claim period, every variation and its evidence, in a single certified record.

Both sides, one record

The same line, claimed and assessed together

The contractor claims a line item and attaches Propeller survey links and supporting documents to substantiate it — evidence the client-side assessor can view directly, right next to the figures, before making one of four decisions.
