Ginger, an independent French engineering consulting group, has been supporting public and private sector clients for over 90 years in the design, planning, and management of their infrastructure, construction, and development projects. Drawing on its complementary areas of expertise and its numerous offices in France and abroad, the group is particularly active in the fields of diagnostics, soil and materials engineering, construction, and the rehabilitation of structures.

With the acquisition of A-Corros, Ginger CEBTP is expanding the expertise of its subsidiaries, particularly in the areas of existing structure assessment and rehabilitation engineering, by integrating cutting-edge capabilities in corrosion analysis, prevention, and treatment. This transaction thus enables the group to strengthen its support for owners and managers of structures facing challenges related to the longevity and preservation of metal structures.

Founded in 2007, A-Corros has established itself as a leading partner, both in France and internationally, in the study, assessment, and treatment of corrosion in metal structures. The company specializes in historic, industrial, and underwater structures, drawing on recognized expertise in predictive analysis and remedial solutions.

The merger between Ginger and A-Corros thus opens up three major avenues for growth: strengthening projects in the field of historic monuments, providing greater support for the redevelopment of brownfield sites and the reuse of old metal structures, and developing collaborations with scientific research institutions.

This acquisition is part of Ginger’s strategy to continuously expand its range of expertise and offer increasingly integrated solutions to address the challenges of preserving, rehabilitating, and enhancing built and industrial heritage.

Founded in 2009, ADVANT Altana has established itself over the past fifteen years as one of the leading independent law firms in Paris, with nearly 100 attorneys, including 28 partners. As a founding member of ADVANT alongside ADVANT Beiten (Germany) and ADVANT Nctm (Italy), the firm offers integrated services across all areas of business law and maintains an international presence through the ADVANT network, which comprises more than 750 professionals across 15 offices.

The renewal of these two bodies reflects the firm’s strength and cohesion and is part of the growth momentum initiated in recent years: team expansion, the rise of ADVANT, the creation of an Advisory Board, and the continuous strengthening of sector-specific expertise.

This wealth of human talent—where emerging talents and seasoned practitioners, as well as French and international cultures, come together—forms the foundation upon which ADVANT Altana is building its future.
