A project can look perfectly healthy on site and still be quietly losing money in the office. Labour is on programme, the client is happy, valuations are being certified without a fight – and three months later the anticipated final account shows a margin that’s largely evaporated. Cost value reconciliation exists to catch that before it happens: a periodic reality check that forces cost, value and risk onto the same page and asks one blunt question – are we actually making the money we think we’re making?
This guide sets out what a CVR actually is, the inputs it reconciles, the process most contractors run it through each month, and the mistakes that quietly wreck the numbers when nobody’s watching for them.
What a CVR actually is – and what it isn’t
A cost value reconciliation compares the value of work completed or recoverable on a project against the cost incurred and the forecast cost to complete, to arrive at a current and anticipated final margin. It’s easy to confuse with two documents that feed into it but aren’t the same thing. The original cost plan or budget is the fixed (or periodically revised) baseline you’re reconciling against, not the reconciliation itself. An interim valuation is contract-facing and constrained by whatever certification mechanism the contract uses – and that mechanism genuinely differs between the major forms, as we cover in our comparison of NEC, JCT and FIDIC – so it tells you what’s payable, not what the job is actually worth once uncertified change, retained risk and accruals are factored in. A cost report is historical again: it tells you what’s been spent, not whether that spend is being recovered. The CVR is the only one of the three that pulls value, cost and forecast together into a single forward-looking commercial position, with commentary explaining why the numbers moved.
The inputs it reconciles
Strip away the spreadsheet formatting and every CVR is built from the same handful of components:
- Value – the amount earned and contractually recoverable from the client to date, including certified work, agreed variations and a realistic, evidenced assessment of unagreed change rather than an optimistic one.
- Cost – actual spend to date across labour, plant, materials and subcontract packages, plus costs already committed but not yet invoiced.
- Accruals – work received but not yet invoiced, most commonly subcontractor packages where the application lags the work actually done on site. Miss these and cost looks artificially low, which flatters margin for exactly as long as it takes the invoice to land.
- Cost to complete – a package-by-package forecast of what’s left to spend, built from current run rates and remaining scope, not last month’s figure rolled forward unchallenged.
- Risk allowances and provisions – sums held against known exposures such as defects, disputed variations, liquidated damages risk or subcontractor default. Released too early, these are one of the most common ways a CVR quietly overstates margin.
- Anticipated final position – the output: forecast final value less forecast final cost, expressed as both a figure and a percentage, and tracked against the previous period so the direction of travel is visible, not just the snapshot.
The process, step by step
Most contractors run a CVR monthly, aligned to the payment and valuation cycle, though a large or fast-moving package can justify a more frequent check. RICS’s own guidance on cost reporting is worth reading in full if you’re setting up a reporting regime from scratch, but the process itself generally runs through four stages:
- Collect – pull cost data from the ledger, subcontract applications and change register, and value data from the current valuation. This step is only as reliable as the measurement it’s built on; if the underlying bill of quantities and rates are out of date or were never properly reconciled to site conditions, the CVR inherits that error and compounds it every month it goes unchecked.
- Reconcile – bring cost and value onto the same reporting period and the same scope. This is where accruals get chased down and where cost coded against the wrong package or cost centre gets caught, before it distorts the picture for that element of work.
- Forecast – project the final cost and final value, folding in remaining risk, known but uncertified change, and realistic productivity for the packages still to come. A forecast that’s simply last month’s number with a small adjustment isn’t a forecast, it’s an assumption wearing a forecast’s clothes.
- Explain – present the movement against the previous period with evidence-based commentary: what changed, why, and what’s being done about it. A CVR that’s just numbers with no narrative tells the reader that something moved, not why it moved or what to do next – and it’s the narrative that turns a spreadsheet into a decision-making tool.
Where CVRs go wrong
The mechanics of a CVR are simple enough that most of the damage happens through a handful of recurring habits rather than genuine complexity:
- Booking unsubstantiated claims as value. Including a variation you expect to win, at the number you’d like to win it at, before it’s agreed or even properly priced, is the single fastest way to make a CVR lie to you.
- Missing accruals. A subcontractor who’s three months behind on applications isn’t three months of free work – it’s three months of cost sitting off the report, waiting to land as a shock.
- Releasing risk allowances early. Provisions held against a live risk that hasn’t actually gone away, released to make this month’s margin look better, tend to be needed again the month the risk materialises – by which point they’ve already been spent on paper.
- Recycling last month’s forecast. Cost to complete that never changes despite productivity, weather or resourcing clearly changing on site is a sign nobody’s actually re-forecasting, just updating a date field.
- Confusing cash timing with earned value. Money received and value earned are not the same thing; a healthy cash position can sit on top of a genuinely deteriorating margin, and a CVR is one of the few reports built specifically to tell the two apart.
Who should be in the room
A CVR that’s compiled by one QS in isolation and emailed round is worth a fraction of one that’s actually discussed. Commercial and quantity surveying staff bring the cost and value detail; the project or site manager brings the reality of what’s actually happening on the ground, which is often the difference between a forecast that holds up and one that quietly assumes last month’s productivity continues unchanged; and finance brings the reconciliation back to the company’s own accounting records, which is the check that stops a CVR drifting into its own parallel version of reality. RICS’s wider construction standards guidance is explicit that reports land better presented and talked through than simply distributed, and that’s just as true internally as it is with a client-facing cost report.
What this means for you
If you’re building or inheriting a CVR process, the return on effort is almost always in the boring parts: a properly maintained accrual list, a cost-to-complete forecast that gets genuinely re-challenged every period rather than rolled forward, and a risk register that only releases allowances when the risk they cover has actually passed. None of that is glamorous, and none of it will show up as a single dramatic finding. What it does is turn the CVR from a monthly formality into the earliest warning system a commercial team has – catching a margin problem while there’s still a package, a variation or a subcontractor account left to do something about it, rather than finding out at final account stage when the only options left are difficult ones.
