Construction projects suffer from decentralised documentation where site engineers, architects, project managers, and clients work from the same drawings but have no shared way to annotate, discuss, and track changes on those documents. Accounting is unstructured, collaboration happens via scattered email threads and messaging apps, and there is no centralised platform connecting all stakeholders across the project lifecycle.

Building a Laravel + Inertia + React application with spatial annotation using @annotorious/react for direct annotation on architectural drawings and images, PDF rendering via react-pdf for document viewing, OCR processing via Tesseract.js for scanned documents, spreadsheet export via xlsx for data extraction, real-time chat with @mentions for stakeholder communication, and interactive project timelines for milestone tracking and coordination. The platform stores spatial coordinates for annotations to preserve context across conversations.
