Clear construction records.
Less risk. Less admin.
RB1 is a lightweight construction project record and communication app for small teams.
It brings internal and external project communications into one place, so decisions, instructions, safety documentation, and completion records stay clear, traceable, and easy to find.
Built for real project teams
Construction projects involve multiple parties all sharing information in different ways.
RB1 provides an affordable single project space where internal and external teams can communicate around specific subjects, keeping conversations linked to the relevant project information rather than scattered across emails, messages, and apps.
