Portugal is entering one of its largest investment cycles in decades: new homes, high-speed rail, the new Lisbon airport, energy networks, and schools and hospitals funded by the Recovery and Resilience Plan.
AICCOPN expects the sector to grow 4.4% in 2026, to around €25.5 billion output. Public works contracts awarded reached €9.7 billion by November 2025, 28% more than a year earlier.
There’s one thing those plans don’t show: who is going to build all of this.
The sector is short of an estimated 80,000 to 90,000 workers. And the hardest gap to close isn’t the number of people. It’s the skills.
Not just a shortage. A skills mismatch.
Portuguese construction companies are clear about where the problem lies. In the European Investment Bank’s 2023 investment survey, almost all of them (97%) said the lack of skilled staff is holding back their investment.
The issue isn’t only finding people. It’s finding people who know how to do the job.
The knowledge walking off site
Portugal is ageing fast, and construction is feeling it. The country’s working-age population is expected to shrink by 5% by 2030 and by more than a fifth by 2050.
The tradespeople who learned by doing, over thirty or forty years, are retiring, and much of what they know was never written down or certified. It’s the kind of knowledge you only see on site: the right sequence, the detail that stops a problem appearing six months later.
Cedefop’s 2025 skills forecast for Portugal makes the point clearly. The number of jobs in building trades is expected to shrink, yet openings will remain, because people keep retiring and must be replaced. And across the economy, almost all job openings up to 2035 will require medium- or high-level qualifications.
In other words, Portugal isn’t just replacing people. It’s replacing knowledge.
Migration fills places. It doesn’t close the skills gap on its own.
Without migrant workers, many Portuguese sites would stop tomorrow. They already make up a large part of the construction workforce, and that share keeps growing.
But migration solves the number problem, not necessarily the skills problem. Some people arrive with no construction experience and need training from day one. Others arrive with real skills that nobody can see, because there’s no simple way to prove or recognize them.
That’s how a qualified electrician ends up working as a laborer. According to Randstad Research, almost half of immigrants in Portugal (43%) work in jobs below their qualifications.
The real task is helping them learn and making what they already know visible.
Different regions, different gaps
Shortages aren’t the same across the country. EURES data shows that each region is missing something different:
| Region | Main construction-related shortages |
| Norte | Metalworking and assembly professionals for industrial construction |
| Centro | Skilled construction workers, especially carpenters and electricians |
| Lisbon Metropolitan Area | Construction workers at all skill levels, plus electrical specialists |
| Alentejo | Construction workers listed among shortage occupations |
| Azores and Madeira | Skilled and unskilled workers, driven by Recovery and Resilience Plan projects |
Nationally, the trades most in demand are carpenters, plumbers, electricians, bricklayers and tilers, painters, and welders.
A one-size-fits-all answer won’t work. Training has to target what each region, and each site, is missing.
The green work is already here
Green construction isn’t a trend for the future. It’s on Portuguese sites today:
- Energy-efficient renovation: insulation, windows, ventilation. Europe needs to double its renovation rate, currently around 1% of buildings a year.
- Renewables in buildings: solar thermal, photovoltaics, heat pumps.
- Material reuse and circular construction: designing and building so materials can be recovered.
- Waste reduction: sorting construction and demolition waste on site.
These are new skills, and few people on site were ever taught them.
Cedefop highlights Portugal’s own Green Skills & Jobs programme: modular, certified training of 25 to 375 hours in energy efficiency, renewables and the circular economy. It shows Portugal already knows the answer is short, modular and certified. The next step is bringing that logic to the people who build on site.
Green Circle: from learning to proof
That’s where Green Circle comes in. It’s an Erasmus+ project bringing together construction companies, training centers and universities from Portugal, Spain, Greece and Germany to develop and test micro-credentials in green skills for construction.
It’s a practical response to the Portuguese challenge, helping construction workers to:
- Acquire new skills through short, focused courses, such as circular economy in construction (10 hours) or solar thermal energy (16 hours).
- Demonstrate what they know through assessment, not assumptions.
- Have it recognized with a credential employers can trust.
- Transfer it from site to site, company to company and country to country, building step by step towards a full qualification.
Portugal’s framework for micro-credentials is still being built. Projects like Green Circle help show how it should work in practice.
The bottom line
Portugal has the projects and the funding. What it’s short of is skills.
Finding more people won’t fix that on its own. The answer is making sure every person on a Portuguese site can learn what the job now demands, prove it, and take it with them.
We don’t just need more hands. We need more skills, and a way to prove them.
