Trimble Tilos is a linear scheduling software designed for infrastructure projects. It uses time-distance diagrams to provide a comprehensive visual overview of project schedules, including equipment, materials, costs, timelines, and budgets, all within a single Gantt chart. The software also enables users to simulate different scenarios, identify potential conflicts, and track project progress in relation to time and distance. Tilos integrates with several other major planning tools, making it a powerful tool for managing and optimizing complex infrastructure projects.
