With the largest market size, construction contributes substantially towards GDP and employment. In 2022, the market was valued at approximately EUR 2.6 trillion and is expected to grow at a CAGR of 4.9% from 2023 to 2028.

• The commercial construction sector is the second largest segment, accounting for over 30% of total revenue.
• The infrastructure construction sector is the third largest segment, accounting for over 20% of total revenue.

The role of the largest construction companies in Europe will be even more important in the coming years. These companies will need to adapt to the challenges facing the market and continue to deliver high-quality construction projects in Europe as well as other regions.

Here are some of the growth perspectives for the European construction market:

• The need for infrastructure investment: The European Union has committed to investing EUR 350 billion in infrastructure over the next decade. This investment will create a significant demand for construction services.
• The growth of the population: The European population is expected to grow by 10% by 2050. This growth will create a need for new housing, commercial space, and infrastructure.
• The increasing demand for sustainable construction: There is a growing demand for sustainable construction methods and materials. This demand will create opportunities for construction companies that are able to deliver green buildings and infrastructure projects.

However, the European construction market also faces some challenges:

• The shortage of skilled labor: The construction industry is facing a shortage of skilled labor. This shortage is expected to worsen in the coming years as the demand for construction services grows.
• The rising cost of materials: The cost of materials, such as steel and concrete, has been rising in recent years. This increase in costs is putting pressure on construction budgets.
• The impact of climate change: Climate change is expected to have a significant impact on the construction industry. Extreme weather events, such as floods and storms, are becoming more common and are causing damage to infrastructure projects.

The largest construction contractors in Europe play a vital role in the market. These large companies are responsible for delivering major infrastructure projects, such as roads, bridges, airports, and power plants. They also play a key role in the construction of residential and commercial buildings apart from their role in providing employment and boosting the GDP of the entire region.
