The firm specializes in road infrastructure (Voiries), utility networks (Réseaux Divers), stormwater management, and green space design, serving municipalities, social housing organizations (bailleurs sociaux), private real estate developers, and retail operators across the Île-de-France region. Its service portfolio spans seven core activities: project management assistance (AMOA), VRD and utility operator coordination, feasibility studies, infrastructure diagnostics, urban engineering, landscape architecture, and sustainable engineering (Ingénierie Durable). The company uses industry-standard tools including AutoCAD, COVADIS, and Civil 3D, with BIM/3D methodologies and an immersive visualization partnership with Volumetric Studio.

The firm's commercial model is fee-based professional services, with revenue generated through project contracts won via competitive public tenders and direct private negotiations. The company holds the LUCIE 26000 RSE label (ISO 26000-aligned, awarded November 2019 and renewed November 2022), and since end-2021 has deployed a proprietary 'calculette carbone' (carbon calculator) on every project to quantify carbon footprint for clients. Notable client engagements include the Issy Cœur de Ville master contractor role (100,000 m² mixed-use development for Altarea Cogedim and Ville d'Issy les Moulineaux), CORA Ermont shopping center parking renovation (26,000 m² for CORA/Galimmo), and VRD engineering for major developers including Nexity, BNP Paribas Immobilier, Woodeum, Capelli, Quartus, and Prologis.
