What A Decade On Site Teaches You That No Recruiter Can Learn From A Database

I spent the first ten years of my working life as a Quantity Surveyor. Not in a back office, not on a desk somewhere far from the work. On live construction sites, on real programmes, for a major tier one contractor. I have now spent the following twelve years doing retained executive search for the UK construction sector.

The first ten years are the reason the second twelve work.

This is not a point about authenticity or sector credentials. Plenty of recruiters in construction claim industry experience. It is a point about what actually happens to your judgement when you spend a decade inside the work before you start assessing the people who do it.

I want to write honestly about what that transition teaches you, because it shapes every conversation I now have with senior candidates and every recommendation I make to hiring leaders. And it explains why so much of what passes for senior hiring in UK construction misses the target.

You stop being fooled by the packaging

The first thing a decade on site teaches you is that the most impressive-sounding professionals are not always the most capable operators. The correlation between how someone presents and how they actually perform is much weaker than people who have never worked on site tend to assume.

I watched this play out hundreds of times over my ten years on programmes. The Commercial Manager who gave polished presentations to the executive team but quietly lost ground in every subcontract negotiation. The Project Manager whose weekly reports told a confident story that the actual site could not sustain. The senior leader who was everyone's pick for promotion based on how they came across in meetings, and whose operational record, when you looked closely, was much thinner than the reputation suggested.

Conversely, there were people on site whose external presentation was unremarkable and whose operational capability was outstanding. The site manager who could not give a corporate presentation to save their life, but who could hold a complex commercial conversation with a difficult subcontractor and resolve it without anyone losing face. The QS two levels below a director who had a sharper commercial instinct than most of the commercial directors on the business.

You learn, through repeated exposure, that presentation is a very poor proxy for performance. And you learn, through reflection on why you kept being surprised by it, to stop trusting your first-impression read of senior professionals. You start looking for other signals.

You learn what the real signals actually are

If presentation is not the signal, what is?

It is the specificity of what someone can tell you about what they have actually done. Real operators can describe the hard moments of their career in concrete detail. The subcontract negotiation where the supply chain partner was refusing to move. The programme reset after a client decision changed the sequencing. The moment the commercial report was wrong and they had to go to the MD and explain why. They can walk you through what they did, why they did it, and what they would do differently.

People who have been performing roles rather than doing the work cannot do this. They speak in generalities. They describe outcomes without the decision-making texture that makes the outcomes believable. When you press for detail, the detail is not there, or it contradicts itself, or it shifts under pressure.

This is not something you can spot without having been inside the work yourself. If you have never been a QS on a live programme, you do not know what a real QS-level conversation about a subcontract dispute actually sounds like. You cannot tell the difference between a senior commercial professional describing a situation they genuinely handled and one they are reconstructing from what they think happened.

Ten years on site gives you that calibration. Every candidate interview I now run, I am listening for the specificity that only comes from having genuinely done the work. It is the single most reliable signal I have, and it is almost invisible to recruiters who have not lived inside the commercial reality of a construction programme.

You stop respecting the wrong things

Another thing that changes when you have worked on site is what you actually respect in a senior professional.

Outside the industry, people tend to respect credentials. The qualifications. The titles. The logos on the CV. The sequence of progressively larger roles. All of these are treated as the signal of quality.

Inside the industry, once you have been on real programmes, you stop respecting those things in quite the same way. You know how easy it is for someone to have collected impressive credentials without ever having delivered anything difficult. You know how many Commercial Directors exist who could not hold a subcontract position to save their lives. You know how many Project Directors have worked on major programmes without ever having been the person who made the decisions that actually mattered.

The credentials are a qualifying filter, not a guarantee of quality. What you respect instead is evidence of genuine delivery under pressure. The specific decisions someone made when it was hard. The team they built or saved. The relationship they held together when it was about to break. The commercial position they defended against a client who was determined to erode it.

These things do not show up on a CV. They show up in conversation, if you know how to ask. But you only know how to ask if you have spent enough time inside the work to know what the right questions are.

You develop a tolerance for operational truth

The most useful thing a decade on site gives you is a tolerance for operational truth. You have been close enough to the work, for long enough, that you are not easily shocked or impressed by descriptions of construction reality.

You know that major programmes regularly encounter serious problems that never show up in the external narrative. You know that most programmes considered successes had significant moments where they could have gone the other way. You know that many of the most respected senior figures in the industry have failures on their record that they have quietly edited out of their public stories.

This matters in senior hiring because the truth about any candidate's career is always more complicated than their CV suggests. Every serious operator has made mistakes. Every senior professional has navigated situations that did not go well. The question is not whether they have a clean record. The question is what they have actually learned, how honestly they can discuss the hard moments, and whether their judgement has genuinely improved as a result.

If you try to assess senior construction talent by looking only at the clean version of their story, you will make consistent mistakes. You will over-weight candidates who have polished their narrative well. You will under-weight candidates whose honesty about difficulty signals real experience. You will miss the difference between professionals who have been tested and those who have been lucky.

Ten years on site teaches you that the sanitised version of anyone's career is never the whole story. It teaches you to ask for the other version, and to listen carefully to how comfortably they can tell it.

You understand what senior roles actually require

Perhaps most importantly, a decade inside the work teaches you what senior construction roles actually require, beyond the job description.

Senior commercial and operational roles in UK construction are not primarily technical positions. The technical knowledge is a baseline, not a differentiator. What actually determines whether someone succeeds at senior level is a combination of less visible things.

Judgement under ambiguity. The ability to make a decision with incomplete information when every option has downsides and the clock is ticking. This is learned through years of making those decisions, some of which went well and some of which did not.

Relational stamina. The capacity to hold productive relationships with clients, supply chain partners, internal stakeholders, and your own team through sustained periods of pressure. This is not about being charming. It is about being consistent, fair, and credible, even when the situation is against you.

Commercial instinct. The ability to read a commercial situation quickly and accurately, to spot the risks that are not yet visible in the numbers, and to make the calls that protect or advance your position. This cannot be learned from textbooks. It is built through repeated exposure to live commercial pressure.

Team leadership that people actually respond to. The ability to get people to do their best work, to stay in the role through difficult moments, and to develop as professionals under your leadership. This is absolutely nothing like what the management books describe. It is forged through years of watching what works and what does not, usually with some painful personal learning along the way.

None of these are things you can assess from a CV. All of them are things you can assess in conversation, if you know what to listen for. What you listen for is shaped by whether you have developed these capabilities yourself, or whether you have only read about them.

Why this matters for the work I do now

The transition from site to search took a genuine shift in skill. Assessing people is different from being a QS, and I do not want to suggest the first ten years of my career made the second twelve easy. The early years of search involved learning a new discipline. Understanding the executive hiring process, the way clients make senior decisions, the dynamics of retained engagement, the craft of candidate assessment at senior level.

But the foundation of the second twelve years is the first ten. Every senior assessment I make is calibrated against what I saw operators actually do on site. Every brief I take is interrogated against what I know real senior roles genuinely require. Every candidate I recommend is someone I believe, based on my own operator-level judgement, could hold the role as described.

The recruiters in UK construction who only work from databases and job descriptions, without the underlying operational experience, cannot make these calibrations. They are doing a different job. They are matching CVs to specifications. That is not the same thing as identifying senior operators who can actually deliver.

I do not say this to dismiss those recruiters. For some kinds of hiring, what they do is fine. But for senior commercial and operational appointments on major UK construction programmes, where the cost of getting it wrong is counted in millions, the gap between CV matching and genuine operator assessment is the gap that determines whether the hire succeeds or fails.

What this means for how you should think about senior hiring

If you are a hiring leader in UK construction and you are choosing who to run your senior searches, the question worth asking is not "how big is their database" or "how fast can they turn it around." The question is "what has prepared them to assess the person who will actually have to deliver this role?"

If the answer is "another recruitment role," that is a weak answer at senior level. Recruitment experience alone does not prepare you to assess senior construction operators. It prepares you to run recruitment processes, which is a different and less valuable thing.

If the answer is "operational experience inside UK construction," then the next question is how much and at what level. A few years of site experience early in a career is different from a full decade of live commercial work. Visits and client-facing roles are different from actually being inside the work when it was hard.

The recruiters whose assessment of senior candidates is most reliable are the ones whose operator experience is deep enough to have shaped their judgement. That operator experience does not have to exactly match the roles they now recruit for. But it has to be real, and it has to be sustained long enough to have taught them the things that only time inside the work can teach.

The honest summary

Ten years on site did not make me a recruiter. It made me someone who, when I eventually became a recruiter, could assess senior construction talent differently.

Those ten years taught me to look past presentation to performance, to ask for specificity where others accept generalities, to respect the right things in a career rather than the impressive-sounding ones, to tolerate operational truth without flinching, and to understand what senior roles actually demand beyond the job description.

Twelve years of search on top of that has sharpened those instincts into something genuinely useful to clients and candidates. But the instincts themselves were built in the ten years before any of it started.

If you are hiring at senior level in UK construction, work with someone whose judgement has been shaped by the work itself. Not someone who has read about it, not someone who has consulted on it, not someone who has run recruitment processes in it. Someone who has actually done it.

The difference shows up in the quality of the hire. Every time.
