If you’re searching for job opportunities but don’t have a university degree, the construction and infrastructure sector could be the ideal path for you. It’s one of the most active and accessible industries in South Africa — and with free online courses, it’s easier than ever to take your first step.

While many sectors are seeing job losses, infrastructure is one of the few industries growing in South Africa. The government has invested billions of rands in public infrastructure, including roads, housing, bridges, and public transport systems. In 2025 alone, over R400 billion was allocated to transport and logistics infrastructure. That means thousands of new jobs — and a huge demand for trained workers.

Whether it’s digging foundations or laying bricks, trained hands are needed everywhere.

Absolutely. While a free online course won’t replace formal technical certification, it can prepare you with the basic knowledge and vocabulary you’ll need to succeed in training programs or land an entry-level job. Many employers value candidates who show initiative, and taking an online course proves you’re willing to learn and grow.

Platforms like Alison provide recognized, high-quality courses that are 100% free and flexible — so you can study even if you’re working or taking care of your family.
