The scope covered corrective, adaptive and evolutionary maintenance of the Vinci Construction France corporate site, co-construction of a structured design system aligned with brand heritage, creation of WordPress “shells” for subsidiaries, and deployment of approximately twenty subsidiary websites. Technical architecture included a Drupal-based corporate website with controlled front-end variations aligned with brand heritage, and a WordPress factory model for subsidiaries with identical back-office and front-office structures. The project also involved planning coordination, delivery supervision, platform administration, contributor preparation and training, as well as guidance towards GDPR-compliant practices in data collection and content management. Constraints included centralised governance, diverse subsidiary profiles with limited digital expertise, private market expectations, and budget accountability and profitability targets.
