We built a powerful tool for our client, that automates the structuring of vast construction data, processing thousands of items in minutes. It features chat-based support using a large-scale language model, enhancing user interaction. GORLEM seamlessly integrates with existing data and documents items such as cost estimates and design data, enabling tasks like cost compilation and emission calculations that once took weeks to be completed in just one minute. Our engineering efforts have significantly improved efficiency in the construction industry.
