The Data Centre Skills Shortage Isn’t Just About Headcount — It’s About Project Lifecycle Experience

The Data Centre Skills Shortage Isn’t Just About Headcount — It’s About Project Lifecycle Experience

Europe's data centre skills shortage is often described as a numbers problem.

But as hyperscale and colocation development continues across Ireland, the UK and mainland Europe, the challenge facing contractors is becoming considerably more complex.

The issue isn't simply whether enough construction and engineering professionals are available.

It's whether organisations can secure people with the right experience for the specific stage of the project they are trying to deliver.

A major data centre project can have hundreds of people mobilised and still face a critical skills shortage if the experience required for its next phase — whether preconstruction, construction, commercial management, system completion or commissioning — isn't available.

This creates what could increasingly be described as an experience bottleneck.

And it means that asking whether a candidate has "data centre experience" is no longer enough.

The Data Centre Talent Challenge Is Changing

Data centre delivery isn't one continuous construction exercise.

It is a series of highly interconnected phases, each requiring different technical knowledge, commercial awareness and leadership experience.

A simplified project lifecycle might look something like:

Preconstruction → Design → Procurement → Construction → Construction Completion → Pre-Commissioning → Commissioning → Integrated Systems Testing → Client Acceptance

Decisions made during one stage can have significant consequences several stages later.

That means having experience somewhere within the lifecycle isn't necessarily enough.

The increasingly important question is:

Where within that lifecycle has the individual actually taken responsibility?

Preconstruction: Where Future Delivery Problems Can Begin

Long before hundreds of tradespeople arrive on site, many of the decisions that will ultimately determine the success of the project have already been made.

During preconstruction, teams need to establish:

• Design responsibilities and deliverables

• Constructability

• Programme strategy

• Procurement schedules

• Long-lead equipment requirements

• Commercial assumptions

• Project risks and opportunities

• Site logistics

• Construction methodology

• Labour requirements

• Systemisation

• Commissioning strategy

This requires experienced Preconstruction Managers, Design Managers, Planners, Estimators, Quantity Surveyors, Commercial professionals and Procurement specialists who understand not only their own discipline but how their decisions affect downstream delivery.

Take long-lead electrical equipment as a simple example.

The programme might identify when switchgear is required on site.

But the actual sequence runs much further back:

Required on Site ← Shipping ← FAT ← Manufacturing ← Technical Approval ← Design Development ← Purchase Order

A delay at the beginning of that sequence can become a major construction or commissioning problem many months later.

The same applies to design.

A design can be technically compliant while still being difficult, expensive or inefficient to construct, test, maintain or commission.

That's why genuine preconstruction experience matters.

The best people don't simply ask:

"Does the design work?"

They ask:

"Can we procure it, build it, test it, commission it and hand it over within the programme and commercial constraints of the project?"

Construction: Turning Strategy Into Production

Once a project moves into full construction, the skills requirement changes again.

Project Directors, Project Managers, Construction Managers, Site Supervisors and Engineers must translate design, procurement and programme into physical production.

The questions become much more immediate:

Is the design available?

Are the materials on site?

Are the workfaces ready?

Do we have sufficient labour?

Are the trades properly coordinated?

Are we achieving the required productivity?

Is the installation being completed to the required quality?

Are we protecting the commissioning sequence?

This is where the difference between having people and having the right people becomes particularly visible.

A Construction Manager may have extensive experience managing large teams, but have they managed the level of M&E integration required on a hyperscale data centre?

A Project Manager may have delivered major construction projects, but have they managed an environment where design, procurement, commercial performance, construction and commissioning all need to converge against aggressive milestone dates?

A Site Supervisor may have excellent trade knowledge, but can they effectively manage labour productivity, workface planning, RAMS, permits, quality inspections and system turnover?

The job title alone doesn't answer these questions.

The project lifecycle experience behind the job title does.

Commercial Experience Is Part of the Skills Challenge

The same principle applies to commercial teams.

A CV might show that somebody has worked as a Quantity Surveyor on several major data centre projects.

But what did they actually control?

Did they manage procurement?

Did they identify and recover variations?

Did they understand contractual entitlement?

Did they manage major subcontract accounts?

Did they control Cost Value Reconciliation (CVR)?

Did they understand Spent versus Earned and use labour productivity information to challenge project performance?

Could they accurately forecast Cost to Complete and Forecast Final Cost?

Most importantly, could they identify when a project was commercially deteriorating early enough to actually do something about it?

There is a significant difference between somebody who can produce a commercial report and somebody who can use commercial information to change the outcome of a project.

As projects become larger, faster and more commercially complex, that distinction becomes increasingly important.

Construction Completion Isn't Project Completion

One of the most important distinctions in data centre delivery is that construction completion doesn't mean the difficult part is over.

As construction progresses, the project increasingly moves from being organised around physical areas and trades towards being organised around systems.

The focus begins to shift:

Construction Completion → Pre-Commissioning → Energisation → Functional Testing → Integrated Systems Testing → Client Acceptance

And the skills requirement changes with it.

The project becomes increasingly dependent on experienced:

• Commissioning Managers

• Electrical Commissioning Engineers

• Mechanical Commissioning Engineers

• QA/QC professionals

• Controls and BMS specialists

• Turnover teams

• Vendor specialists

• System owners

This is where the experience bottleneck can become particularly visible.

A project could have 300 people working on site and still have a critical skills shortage if it doesn't have enough people capable of taking systems through the final stages of testing, commissioning and client acceptance.

Adding more general construction labour doesn't necessarily solve that problem.

The required experience does.

The Experience Bottleneck

This is why the European data centre talent challenge should increasingly be viewed as an experience bottleneck, rather than simply a headcount shortage.

There may be candidates available in the wider construction market.

There may even be candidates with previous data centre experience.

But the real question is whether those candidates have already taken responsibility for the specific problems the next project needs them to solve.

A Project Manager who has delivered shell and core isn't automatically a Project Manager who has taken a hyperscale facility through commissioning and client handover.

A Quantity Surveyor who has managed procurement and variations isn't necessarily somebody who has controlled CVR, Spent versus Earned, labour productivity and final-account exposure on a major M&E package.

A Construction Manager with excellent installation experience isn't automatically somebody who understands systemisation, turnover and commissioning readiness.

And a Preconstruction Manager needs to understand how decisions being made today could affect procurement, construction and commissioning 12 or 18 months later.

The difference isn't necessarily the number of years somebody has spent in the sector.

It's what they've actually been responsible for delivering during those years.

"Data Centre Experience" Is No Longer Specific Enough

For years, one of the first questions asked during recruitment has been:

"Do they have data centre experience?"

It's still an important question.

But it shouldn't be the last one.

A candidate may have spent three years working on data centres without ever taking responsibility for a critical programme, commercial, construction or commissioning outcome.

Another candidate may have fewer years in the sector but have personally delivered a major package through procurement, construction, testing and client acceptance.

Which candidate has the stronger experience?

The answer isn't necessarily the person with more years.

Increasingly, hiring decisions need to move beyond sector exposure and towards evidence of delivery.

Instead of simply asking:

"Have you worked on a data centre?"

Hiring managers should be asking:

"What stage of the project did you personally take responsibility for?"

"What was the scale and complexity?"

"What decisions were you accountable for?"

"What went wrong?"

"How did you respond?"

"What measurable outcome did you deliver?"

Those questions tell us considerably more than the project name printed on a CV.

Recruitment Needs to Follow the Project Lifecycle

There is another consequence of this.

Workforce planning needs to happen earlier.

Waiting until a project reaches a particular phase before recruiting the specialists required for that phase creates unnecessary delivery risk.

The recruitment strategy should follow the project programme.

During preconstruction, organisations need people capable of de-risking design, procurement, programme, commercial strategy and constructability.

As mobilisation and construction approach, the focus moves towards project leadership, construction management, engineering, supervision, commercial management, EHS and quality.

As the project moves towards completion and commissioning, demand shifts again towards commissioning, controls, QA/QC, turnover and system specialists.

In other words:

The resource plan should evolve with the project lifecycle.

Organisations that understand this can begin identifying and engaging talent before those skills become critical.

Those that don't may find themselves competing for the same limited pool of specialists precisely when the project can least afford to wait.

The Question Is Changing

The European data centre sector undoubtedly needs more people.

But headcount alone won't solve the talent challenge.

The more important question is becoming:

"What experience do we need, at what stage of the project, and when do we need it?"

That requires a deeper understanding of both recruitment and project delivery.

For hiring managers, perhaps the most useful question is no longer simply:

"Has this person worked on a data centre?"

It should be:

"What stage of the project have they personally taken responsibility for, what problems did they encounter, and what measurable outcome did they deliver?"

Because on increasingly complex data centre projects, having experience and having the right experience are two very different things.

How Evergreen Talent Group Approaches Data Centre Recruitment

At Evergreen Talent Group, we support Construction & Engineering organisations across Ireland, the UK and Europe, with particular expertise across the data centre market.

Our approach is based on understanding where an individual fits within the project lifecycle — not simply whether "Data Centre" appears on their CV.

That means looking beyond job titles and project names to understand the candidate's actual responsibilities, technical exposure, project scale, stage of delivery and measurable outcomes.

From Preconstruction, Design, Planning, Estimating and Commercial, through Project Management, Construction, EHS and Quality, and ultimately into Commissioning and Handover, the objective is the same:

Match the experience required by the project with the experience the individual has actually delivered.

Because as the European data centre market continues to develop, identifying the right experience at the right stage of the project lifecycle may prove just as important as finding the people themselves.
