What erregi srl does

Erregi Srl is an Italian engineering, architecture and urban planning firm founded in 1986 and headquartered in Rome, providing integrated multidisciplinary design services for large-scale transport infrastructure. The company operates three core service divisions: Transportation Infrastructure Planning (railways, metro systems, roads, airports, tramways), Structural Engineering Design (performance-based design for complex infrastructure and buildings), and Architectural Design (large-scale infrastructure, sustainable architecture, environmental impact studies). Underlying design work is delivered through BIM-based multidisciplinary coordination and includes differentiated capabilities in eco-sustainable infrastructure, exemplified by an energy-self-sufficient metro station design (photovoltaics, geothermal climate control, natural ventilation) presented at Shanghai EXPO 2010.

The firm operates as a project-based professional services business, winning work primarily through competitive public tenders and direct negotiations with government authorities and state-owned infrastructure enterprises. Core clients include Italian state railway entities (RFI, ITALFERR), ANAS, METRO C, plus international counterparties such as CWG (Riyadh Metro Line 3), GEASAR (Olbia Airport), and the Kurdistan Regional Government. Project scopes span feasibility studies, preliminary, final and detailed design, and construction supervision across rail, metro, road, port, airport, and urban development mandates.

Erregi maintains an international footprint with completed engagements in 12+ countries across Europe, the Middle East, Asia, Africa, Latin America and the Caribbean, supported by a team of more than 40 engineers, architects and project designers. In October 2025, Erregi was acquired by Artelia Group and became part of Artelia Italia, strengthening the parent's infrastructure and mobility capabilities.
