Fieldwire is a mobile-first (iPad / iPhone, Android) collaboration platform designed for construction foremen, superintendents and engineers. The application allows field workers to access up-to-date information like blueprints, files and tasks directly on their mobile device. Fieldwire focuses on the effective collaboration of field workers around three core use cases: -Plan viewing & versioning -Issue tracking -Task management & scheduling The collaboration platform is structured around plans and trades allowing users to create tasks attached to specific locations on plans as well as add comments, photos and annotations in each of them. Tasks are automatically uploaded to a centralized server (for automatic archiving and reporting) and dispatched to the other members on the project through wifi and cellular network. Fieldwire works both offline and online allowing users to continue working in conditions where little or no network connectivity is available.
