THE FIRM

Infrastructure economics in support of sustainable change.

Blue Arches supports public and private organisations with their transport, infrastructure and data projects. Our role: informing decisions, structuring projects and supporting their delivery.

Complementary backgrounds, a shared ambition.

Founded in 2022 by Nicolas Gohel and Tarak Bouacida, Blue Arches brings together expertise in infrastructure economics, finance and the management of complex projects. We combine sector knowledge with economic analysis to build answers tailored to each context. In 2024, Victor-Hugo Macedo joined the firm to strengthen our data and AI offering.

Three ways to transform infrastructure.

New infrastructure

Feasibility studies, business plans, contractual and financial structuring: securing decisions and preparing the delivery of new projects.

Infrastructure modernisation

Audits, concession handovers, contract renewals and transitions to new management models: adapting assets and their business models.

New services and innovation

Market studies, economic and financial modelling, socio-economic impact assessment: informing decisions and supporting new solutions.
