# The 30 largest Construction companies in the Nord department

Tamtam tracks 49 Construction companies headquartered in the Nord department. This list ranks the 30 largest by number of employees on LinkedIn, led by Ramery, Bouygues Batiment Nord-Est and Rabot Dutilleul Construction. Their median headcount is 62. Half of them were founded in 2001 or later. The most common headquarters are Lille (3), Villeneuve-d'Ascq (3) and Marcq-en-Barœul (2).

These construction companies in the Nord department are primarily mid-sized and large firms, with a focus on civil engineering, building construction, and specialized infrastructure. Many of them provide comprehensive services from design to completion. For example, Ramery specializes in road construction and urban development, while Bouygues Batiment Nord-Est focuses on designing and operating high-quality buildings. Rabot Dutilleul Construction handles new construction and rehabilitation, and Sogea Caroni, a VINCI Construction subsidiary, operates in building and civil engineering.

A notable pattern among these companies is their geographical concentration. Many are headquartered in or around Lille Métropole, with locations such as Marcq-en-Barœul, Wasquehal, Roubaix, and Villeneuve-d'Ascq appearing frequently. This suggests a regional cluster of construction expertise in the Nord department.

## 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 11, 2026.
