8 Fascinating Facts About the Construction Industry

The construction industry has been shaping the world around us for thousands of years, leaving its mark on everything from ancient monuments to modern skyscrapers. Whether you’re deep in the trade or just curious about how the sector works, there’s a lot more to construction than bricks and mortar. Let’s dig into eight surprising facts about the construction world that might just change the way you see it.

Construction—a global powerhouse

It might not always grab the headlines, but construction is one of the biggest industries in the world. The global sector is worth over $10 trillion each year, contributing around 13% of the world’s GDP. Closer to home, the UK construction industry is a heavyweight in its own right, valued at around £110 billion annually—roughly 7% of the country’s GDP. With infrastructure projects, residential builds, and commercial developments always in demand, it’s no surprise that companies that build houses are a key pillar of the economy.

One of the riskiest jobs out there

Everyone knows construction isn’t the safest job, but the statistics are eye-opening. The industry accounts for more than 20% of all workplace fatalities worldwide. Here in the UK, construction made up 30% of all fatal workplace injuries in 2022/23, according to the Health and Safety Executive. While safety regulations and better equipment have helped improve conditions, the nature of the work—often involving heights, heavy machinery, and unpredictable weather—means the risks can never be eliminated.

World’s second-largest employer

It’s difficult to overstate just how many people construction puts to work. As of 2021, the industry employed around 174 million people worldwide, making it the second-largest employer after agriculture. That’s roughly 7% of the global workforce. In the UK alone, around 2.7 million people—nearly 10% of the country’s workforce—are employed in the sector. From new build contractors and architects to bricklayers and surveyors, the construction industry offers an enormous variety of careers across the supply chain.

A male-dominated industry

Despite the growing push for diversity, women are still heavily underrepresented in construction. Globally, they make up just 10% of the workforce—and the UK doesn’t fare much better. Only 13% of the UK construction workforce is female, with even fewer working on-site. However, things are starting to shift. More companies are offering flexible working options, and industry campaigns are encouraging more women to consider careers in the sector.

Skilled workers in short supply

You might think, with millions of people employed in construction, there’d be no shortage of workers—but the opposite is true. The sector is facing a global skills crisis, with estimates suggesting there could be a shortfall of over 85 million workers by 2030. In the UK, nearly 80% of construction companies report struggling to find enough skilled employees. With an ageing workforce and fewer young people entering the trade, the industry is crying out for fresh talent.

Construction waste—a major challenge

While construction is all about building, it’s also one of the biggest contributors when it comes to waste. The sector generates more than 30% of global waste and consumes over 50% of the world’s natural resources. The UK alone produces around 60 million tonnes of construction and demolition waste every year. However, things are starting to change. Sustainable building methods like modular construction, prefabricated materials, and eco-friendly technologies are helping to cut waste and reduce the industry’s carbon footprint. The UK’s target of net-zero carbon emissions by 2050 is driving innovation, making green building practices more important than ever.

Technology is shaking things up

The days of construction being all hard hats and heavy lifting are long gone. Modern technology is transforming the industry at every level. Tools like Building Information Modelling (BIM) allow companies to create detailed 3D digital plans before a single brick is laid. Meanwhile, 3D printing, robotics, and AI are speeding up builds and cutting costs. Modular and prefabricated construction methods are also gaining traction, making projects faster, more efficient, and more sustainable. Technology is no longer the future—it’s already reshaping how house building companies operate today.

China’s mind-blowing concrete consumption

If you want proof of how quickly construction can change the landscape, just look at China. Between 2011 and 2013, China used more concrete than the US did during the entire 20th century. Rapid urbanisation, population growth, and huge infrastructure projects fuelled this staggering demand. While impressive, the environmental toll of such large-scale construction highlights the need for more sustainable building methods in the future.
