RIB Site offers comprehensive management of digital and mobile construction processes and offers every company a new way of jointly designing construction processes. Collaboration between the office and construction site, as well as collaboration with external project participants such as consortium partners, the customer or executing trades, is future•proof with RIB Site. Simply store and retrieve documents, plans and defects, define tasks or share them via communication. With RIB Site, you can release documents individually for project participants or trades on a task•related basis or upload them directly via the portal mode or have them released. In this way, employees in the office and on the construction site always work with the correct level of knowledge and save coordination loops and consultation effort. With the convenient search options and integrated full•text search, users can quickly find the right documents and forward them to colleagues or external project partners via a link.
