The construction companies in Lombardy include large, established groups and mid-sized firms. Many specialize in large-scale infrastructure projects, sustainable building, and specialized construction services. Webuild and Salini Impregilo are global industrial groups focused on sustainable mobility, clean energy, and water infrastructure. Hilti Italia provides technology-leading products and systems to the construction industry, while Heidelberg Materials Italia specializes in cement production.
A notable pattern is the concentration of headquarters in Milan, which hosts several major players like Salini Impregilo and EXA Group, an international general contractor for luxury projects.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
