Does Your Quantity Surveyor Actually Make You Money?

The QS Value Question

Here's a question that makes commercial directors uncomfortable: What's the return on your QS investment?

You know what they cost. Salaries, overheads, software, training. But what do they generate? Not in vague terms like "commercial management" but in actual, measurable pounds recovered, protected, and created.

Most companies can't answer this question. Which means most companies don't actually know if their commercial function is a cost centre or a profit driver.

The Two Types of QS

After working with dozens of commercial teams, a pattern emerges. QS professionals tend to fall into two categories:

The Administrator

Processes applications. Checks invoices. Maintains records. Does the job description competently. Keeps things ticking over. Rarely identifies opportunities. Waits for problems to arrive rather than preventing them.

The administrator is necessary but not sufficient. They're the cost of compliance, not the engine of value.

The Value Creator

Hunts for entitlement. Spots variations before they slip through. Challenges unsubstantiated contra-charges. Builds claims proactively. Recovers money that would otherwise be lost.

The value creator doesn't just manage the commercial position. They improve it.

Measuring QS Value

If you want to know whether your QS makes you money, you need to measure specific outcomes:

1. Variation Recovery Rate

Of all the variations identified on your projects, what percentage gets recovered? Industry average sits around 40-50%. Top performers achieve 80%+. The gap between average and excellent on a £20M project with £2M of variations is £600K-800K.

2. Claim Success Rate

Of claims submitted, what percentage achieves the target recovery? Are you settling for 50p in the pound because claims aren't properly substantiated? Or achieving 90p+ because the evidence is bulletproof?

3. Contra-Charge Defence

How much do you lose to contra-charges versus how much you should lose? Many contractors accept contra-charges without proper challenge. A good QS reduces contra-charge exposure by 30-50%.

4. Time Bar Prevention

How many claims get time-barred? Every time-barred claim represents 100% unrecovered value. If your QS misses notice periods, they're literally costing you money.

5. Final Account Speed

How long do final accounts take to close? Extended final accounts tie up retention, delay cash, and incur ongoing management costs. A good QS closes accounts faster.

The Value Calculation

Here's a simple framework for quantifying QS value:

Value Created = Variations Recovered + Claims Won + Contra-Charges Defeated + Time Bar Savings

Value Protected = Margin Protected + Cash Flow Improved + Disputes Avoided

Compare this to the fully loaded cost of your commercial function. If value created and protected exceeds cost by 3x or more, your QS is definitely making you money. If the ratio is 1:1 or less, you have a commercial administration function, not a value creation function.

Why Most QS Teams Underperform

If value creation is so valuable, why don't all QS teams do it? Several factors:

Workload

QS teams are often stretched across too many projects. When you're drowning in applications and invoices, proactive value hunting becomes impossible. The urgent drives out the important.

Information

You can't recover what you don't know about. If site teams don't report variations, if diaries don't capture instructions, if the QS lacks visibility of what's happening, opportunities slip through unseen.

Culture

Some organisations treat commercial functions as administrative overhead rather than strategic assets. This becomes self-fulfilling. Treated as administrators, QS teams behave as administrators.

Tools

Spreadsheets and manual processes absorb time that could be spent on value creation. Every hour spent reformatting CVRs is an hour not spent hunting variations.

Moving from Cost Centre to Profit Driver

If you want your QS function to make money rather than cost money, focus on three things:

1. Information Flow

The QS needs to know what's happening on site. Daily. Not filtered through fortnightly progress meetings, but real-time awareness of instructions, changes, and events. Better information flow directly increases variation identification.

2. Protected Time

Block time for proactive commercial work. If your QS spends 100% of their time on reactive administration, they have 0% time for value creation. Even shifting to 80/20 transforms outcomes.

3. Measurement

Track the metrics that matter. Variation recovery rate. Claim success rate. Time to close. When you measure value creation, value creation improves.

What This Means for Your Projects

Your QS team either makes you money or costs you money. There's no neutral position. Every variation not identified is margin lost. Every claim not substantiated is entitlement surrendered. Every time bar missed is cash gone forever.

The question isn't whether you can afford to invest in commercial excellence. It's whether you can afford not to. The maths almost always favours investment.

Take a hard look at your commercial function. Are they creating value or processing paperwork? The answer determines your project margins more than you might think.
