There is nothing inherently wrong with that. Physical progress, measured quantities, valuation, certification and payment are different dimensions of project delivery, each following its own contractual mechanism.
The problem begins when they are reported independently, reconciled periodically and presented to management as though they describe the same position.
A programme may indicate that the project is progressing satisfactorily. A valuation may show a different level of recognised work. A payment certificate may reflect further adjustments. And the cash received may tell a fourth story.
All four positions may be correct. But without a clear connection between them, management cannot see what the project has achieved, what has been commercially recognised and what remains outstanding.
This is not simply a reporting problem. It is a commercial information continuity problem.
1. PHYSICAL PROGRESS IS NOT COMMERCIAL PROGRESS
Physical progress measures the advancement of activities, expressed through completed quantities, weighted milestones, installed systems or other measurable outputs.
Commercial valuation asks a different question: what is the value of the work performed under the applicable contractual valuation mechanism?
A 40% figure may be built on programme weights, earned quantities or physical milestones. It does not necessarily mean that 40% of the Contract Price has become eligible for certification. Some activities carry more commercial value than others. Certain milestones require full completion before payment falls due. Other contracts permit progressive measurement.
The payment mechanism determines how physical execution becomes commercial value. A progress percentage is an important indicator, but it is not, by itself, a payment entitlement.
2. FOUR STEPS, FOUR DIFFERENT QUESTIONS
Measurement establishes the quantity or extent of work executed and recognised for assessment.
Valuation determines the contractual value of that work, using the applicable rates, prices, milestones or valuation rules.
Certification establishes the amount recognised through the contractual certification process, including adjustments.
Payment is the actual settlement of the certified amount.
Work may be executed but not measured. Measured but not valued. Valued but not certified. Certified but unpaid.
None of these gaps is automatically a contractual failure; they may reflect normal sequencing. But they must remain visible and reconcilable. Otherwise, a single progress figure conceals several materially different commercial positions.
3. THE MONTHLY RECONCILIATION PROBLEM
In many projects, the monthly valuation is assembled from several sources: the BOQ for pricing, site records for quantities, a variation register for changes, spreadsheets for cumulative values, and separate records for advances, retention and previous certificates.
This can work, particularly with experienced teams and disciplined document control. But it means the commercial position is reconstructed at reporting intervals rather than maintained as project information changes.
Each cycle, teams must re-establish which quantities are current, which variations are approved, which rates apply and what has already been certified. A quantity updated in one file but not another. A variation included in a forecast before formal approval. A revised rate in a valuation without its approval status visible. A previous period adjusted without a clear history.
The result is not necessarily an incorrect valuation. It is a process that needs repeated reconciliation before anyone trusts the number, and that reconciliation consumes time better spent analysing exposure and supporting decisions.
4. VARIATIONS: THE STATUS OF THE WORK VS. THE STATUS OF ITS RECOGNITION
A change may be identified, instructed, submitted for valuation, assessed, approved, incorporated into the contractual baseline, executed and certified, and not always in that order. Work may be instructed before its price is agreed. An assessment may stay provisional while execution progresses.
An executed variation is not necessarily an approved variation, and an estimated value is not necessarily a certified entitlement.
Approved changes should enter the contractual baseline in accordance with the contract, while pending changes remain separately identifiable. Without that separation, reports mix confirmed values with estimates and make the commercial position look more certain than it is.
5. FROM VALUE OF WORK TO AMOUNT DUE
Even when the value of executed work is established, the amount payable can differ, because of advance recovery, retention and other contractual adjustments.
A simplified example:
| Commercial indicator | Illustrative value |
|---|---|
| Original Contract Price | €10,000,000 |
| Physical progress reported | 40% |
| Cumulative value of work assessed | €3,900,000 |
| Cumulative value certified | €3,700,000 |
| Retention held (5%) | €185,000 |
| Advance recovered to date | €400,000 |
| Net amount due on certified value | €3,115,000 |
| Pending variations under assessment | €500,000 |
Figures are illustrative and do not imply a specific contractual mechanism.
The €200,000 between assessed and certified value needs an explanation. The pending variations remain separate until their contractual status allows recognition. And cash actually received may differ again.
The objective of commercial reporting is not to force these figures to match. It is to explain why they differ and preserve the contractual basis for each amount.
6. A CONTINUOUSLY MAINTAINED COMMERCIAL POSITION
What would change if the commercial position were maintained as events occurred?
A quantity is confirmed, and cumulative progress updates. A variation is approved, and the baseline updates. A valuation is prepared, and advance recovery and retention are calculated by the configured contractual rules. A certificate is finalised, and its values and history are preserved.
Each step feeds the same commercial record, without recreating information in disconnected files.
This does not mean every recorded event becomes a certified amount. Draft, assessed, approved and certified information must stay distinct. Nor does it replace the judgement of the Quantity Surveyor, Cost Manager or Engineer.
A continuously maintained commercial position is not a continuously approved position. Approvals, authority and certification remain governed by the contract. Digitalisation should support those controls, not bypass them.
The same applies across Project Controls. The programme shows the sequence of activities, progress measurement shows what was executed, valuation shows what is recognised, and forecasting estimates the outcome. These disciplines should inform one another without being confused. A reliable commercial record is a foundation for cost reporting, not a substitute for forecasting, which needs remaining work, commitments and risk.
7. WHAT COMMERCIAL CONTINUITY REQUIRES
The industry has invested heavily in document management and dashboards. Yet a project can produce extensive digital information without maintaining a coherent commercial position. The next improvement is not another report. It is better continuity between the events that change the project and the records that administer their commercial consequences.
That requires:
A consistent contractual baseline that separates original contract information from approved changes.
Traceable measurement and valuation, linked to quantities, rates, rules and reporting periods.
Controlled approvals, so draft, assessed, approved and certified information remain distinguishable.
Consistent calculations for advance recovery, retention and other adjustments.
Preserved history, with corrections managed through controlled revisions rather than silent overwriting.
Reconciliation rather than assumption, with differences between progress, valuation, certification and payment visible and explainable.
These are not software features. They are commercial governance requirements that digital systems can help enforce.
THE PRINCIPLE
A project does not become commercially controlled because its dashboard is current. It becomes better controlled when the information behind the dashboard is consistent, traceable and governed by the contractual mechanisms that determine its meaning.
Physical progress shows what has advanced. Measurement establishes what has been executed. Valuation determines its contractual value. Certification records what has been recognised. Payment establishes what has been settled.
The objective is not to eliminate the differences between them, but to preserve the relationships.
Commercial management should not begin when the monthly valuation is assembled. It should be maintained throughout the reporting period, as the project evolves.
HOW ACC TRUST CAN SUPPORT
ACC TRUST supports contractors, developers and project teams in improving commercial management, valuation processes and contract governance, with a focus on consistent commercial information, clear contractual baselines, traceable valuation records and reliable certification.
This thinking also underpins the development of ACC Commercial Valuation, a software application designed to connect BOQ information, measured progress, monthly valuations, approved changes, advance recovery, retention and certification history within a structured commercial workflow. It is not intended to replace professional judgement or the contractual certification process, but to reduce unnecessary reconciliation and make the project’s current position easier to understand and verify.
