What Crescendo does

Crescendo Conseil is a French professional services firm founded in 2010 by Fabien Allard in Châteauroux, specialized in construction consulting for public sector clients. The firm provides programming studies (feasibility analysis and project specification), operations management (AMO/MOD), technical engineering studies (acoustic, thermal, energy performance, construction economics), and construction scheduling and coordination (OPC, DET). It also operates a ministry-authorized air tightness testing service and runs a Crescendo Sport sub-brand focused on sports facility projects.

The business model is project-based professional services revenue earned through competitive bidding on French public procurement contracts (marchés publics, MAPA). All clients are public or semi-public entities: municipalities, regional councils, hospitals, schools, EHPADs, defense infrastructure bodies, and vocational training centers. Crescendo differentiates through a multidisciplinary team of 27 specialists, OPQIBI certifications across programming, operations management, OPC and acoustic engineering, and a dedicated in-house legal cell for public procurement compliance.

The firm has grown from a single Châteauroux office to nine regional agencies across Centre-Val de Loire, Pays de la Loire, Nouvelle-Aquitaine, Bretagne, and Auvergne-Rhône-Alpes, with stated coverage of additional regions (Grand Est, Bourgogne-Franche-Comté, Île-de-France) and a cumulative 470+ project reference base.
