• Egis: Large French engineering group active in transport infrastructure, bridges, buildings, and energy. Operates as both a competitor and a potential prime/client for Equilibre on major French and international infrastructure mandates.
• Arup: Global engineering, design, and consulting firm with leading structural engineering practice. Competes for landmark architecture and complex-bridge mandates and frequently acts as a prime or sub-consultant on the megaprojects where Equilibre also delivers execution studies.
• INGEROP: French independent engineering consultancy active in buildings, infrastructure, energy, and environment. Competes for structural execution studies and engineering consultancy mandates, particularly in France and on industrial/energy projects.
• Buro Happold: Global engineering consultancy with strong structural and bridge practices serving infrastructure, buildings, and energy clients. Competes for complex-steel and bridge execution work, particularly on international megaprojects where Equilibre also operates.
• Tractebel: Engineering consultancy owned by ENGIE with extensive bridge, infrastructure, and energy expertise across Europe. Competes in the same French and international tender markets for execution studies on complex steel and concrete structures.
