Valuation Checked

Every interim application assessed independently before it is certified – not after the money has left the account.

Forecasts erified

Every instruction logged, valued and agreed in principle before the next application cycle.

Forecasts Verified

Independent cost reports based on actual progress – not on the contractor’s commercial position.

Account Reconciled

From the variation register to the agreed final sum – we close the account cleanly, every time.

THE PROBLEM THIS SERVICE SOLVES

Uncontrolled Cost Becomes a Dispute.

Construction Cost Control exists because most projects reach practical completion without a properly managed commercial record. Valuation overpayments accumulate. Variations go unpriced. Forecasts reflect the contractor’s position rather than yours. By the time the final account is submitted, the dispute is already formed – and the paper trail needed to challenge it does not exist.

Interim valuations assessed and approved without independent verification, creating overpayment risk from the first application.
Variations accumulating without a structured register — each instruction unpriced and unresolved until final account, by which point the dispute is already formed.
Early allowances and provisional sums are carried forward long after scope and design have moved on, hiding real cost growth.
Client and contractor teams assume “the numbers add up”, only to discover commercial exposure at re‑basing, negotiation or final account.

HOW THIS SERVICE HELPS

Turning Project Data into
Defensible Cost Control

Construction Cost Control pulls together BIM quantities, site measures, change logs and cost reports into one commercial view you can actually rely on. It sits alongside your Digital Cost Planning, Strategic Procurement and Change & Variations so decisions stay joined up from live works to final account.

Send a current project and we will show you where quantity, change and cost risk sit.

 

Structured, project‑based quantities

We clean and organise quantities so they match how contracts, packages and valuations are really being run on the job – not just how they sit in a spreadsheet.

Cross‑checks against drawings and change

We cross‑check quantities with drawings, instructions and change records to expose missing scope, overlaps and commercial grey areas before they hit negotiation.

Commercial insight before negotiation

We flag where assumptions, records or programme shifts could weaken your position, giving you time to tighten Construction Cost Control before re‑basing or final account.

Live link with
cost and risk

We keep a live connection between progress on site, quantities, Change & Variations and your commercial reporting, so cost control, risk and records stay in step.

PROJECT TYPES WE SUPPORT

Projects That Need Tight Cost Control

Construction Cost Control delivers the most value on projects where the commercial risk sits with the client or funder and where variations, valuations and forecasts need an independent hand on them throughout delivery.

We focus on schemes where the contractor relationship, scope complexity or funder reporting requirements make it essential to have a defensible commercial record – from the first interim application through to final accounts and agreed final sum.

Construction Cost Control
High‑End Residential
Independent valuation and variation control on premium residential schemes where specification changes and client instructions generate significant cost movement throughout delivery.
Residential Developments
Cost control across multi-unit schemes where funder reporting requirements demand independently verified forecasts and a clear variation record at each stage.
Mixed‑Use Developments
Commercial oversight across multiple packages and interfaces, where variation exposure and phased handovers between uses create the highest cost risk on site.
Complex Phasing Projects
Structured cost control where phasing, enabling works and sequential procurement generate variation and prolongation claims at every stage of delivery.
Building Refurbishment
Independent assessment of unforeseen condition claims, variation instructions and contractor cost submissions on schemes where the scope was never fully defined at tender.
Commercial Risk Environments
Senior commercial oversight on contentious projects where the contractor relationship is under strain and every valuation, instruction and forecast requires a defensible paper trail.
When this service is typically required

When Construction Cost Control Matters Most

Construction Cost Control works best when the commercial controls are established before the contractor submits the first interim application – so that valuations, variations and forecasts are managed from day one, not recovered after the fact.

We focus on the stages where independent commercial oversight can prevent overpayment, contain variation exposure and keep the cost position defensible from contract award through to final account.

Contract Award Body

The variation register, valuation template and cost reporting format are established before the first application – so the commercial baseline is set on day one, not reconstructed later.

During Delivery

Each interim valuation is assessed independently, the variation register is maintained live and cost forecasts reflect actual progress – not the contractor’s commercial position.

At Practical Completion

The final account is managed from a position of complete contemporary records – all variations reconciled, prolongation assessed, final sum agreed.

On Contentious Projects

Where the contractor relationship is under strain, an independent commercial record is established and delivery is managed on a defensible basis.

KEY RISKS WE ADDRESS

Protecting Your Commercial Position Throughout Delivery.

Cost exposure on live construction projects rarely arrives as a single event. It builds quietly – through unchecked valuations, unregistered variations and forecasts that no one on the client side has independently verified.

Construction Cost Control exposes these risks early, so independent commercial oversight can challenge contractor submissions, maintain a defensible record and protect your position before the final account is submitted.

Protecting Your Commercial Position Throughout Delivery.
Overpayment on Interim Applications
Contractor valuations are prepared by the contractor's commercial team. Without independent assessment, overpayments on preliminaries, materials on site and work claimed but not yet complete are routine. Every application is checked before it is certified.
Uncontrolled Variation Exposure
Every instruction not priced and agreed in principle becomes a potential dispute. A live variation register - each item logged, valued and agreed before the next valuation cycle - removes the conditions in which disputes form at final account .
Disputed Final Account
Projects without structured cost control during delivery almost always arrive at a contested final account. The variation register and valuation record maintained throughout construction is the document that prevents that dispute from forming in the first place.
WHO THIS SERVICE IS FOR

Clients Who Carry the Commercial Risk on Site

Construction Cost Control is for clients, developers and funders who are accountable for the out-turn cost – not just the programme or the design. We work with people who need an independent commercial function on their side, producing assessments and records that hold up under scrutiny at valuation, variation and final account.

HOW CONSTRUCTION COST CONTROL WORKS

A Clear, Structured Commercial Process

We follow a straightforward four-step process so that Construction Cost Control is operational from contract award – not after the first valuation has been overpaid or the first dispute has formed.

FREQUENTLY ASKED QUESTIONS

Construction Cost Control – Frequently Asked Questions

Quick answers to the most common questions about independent commercial oversight during construction delivery.

Can you take over cost control on a project that has already started?
Yes. The existing valuation history is assessed, the variation register reconstructed from available records and an independent cost forecast produced from the current position. The earlier we are engaged, the less ground needs to be recovered - but we can step in at any stage.
We already have a project manager. Do we need Reltic as well?
Project managers manage programme, design coordination and site progress. Most do not carry the commercial depth to assess contractor valuations, manage variation entitlement or produce defensible cost forecasts. These are distinct functions - we work alongside project managers as the independent commercial function.
How do you handle disagreements with the contractor during construction?
The approach is to prevent disputes from forming. A well-maintained variation register, agreed in principle at each stage, removes the conditions in which disputes develop. When disagreements arise, they are dealt with on the basis of contract entitlement and contemporary records.
What does independent cost control cost compared to the risk it manages?
On a £5m project, a single unassessed valuation overpayment or an unmanaged variation register can produce six-figure exposure at final account. Reltic's fee for cost control on a project of that scale is a fraction of that risk. We charge a fixed monthly retainer or an agreed lump sum - not a percentage of project value.
Do you work under JCT, NEC or bespoke contracts?
We work across all standard forms in the UK market - JCT Standard, Design and Build, Intermediate and Minor Works; NEC3 and NEC4; and bespoke development agreements. The contract form determines the commercial mechanisms. Our process is adapted to each.
What does a typical first engagement look like?
We review the contract, accepted tender and current commercial position. Within the first two weeks, the variation register and valuation assessment template are in place and the first independent cost forecast is produced. From that point, the process runs to a fixed monthly cycle.
