As infrastructure projects became larger, longer, and more complex, traditional planning tools struggled to represent the relationship between time, location, and construction progress in a way that planners could easily understand and manage.

This challenge inspired Human Dialog's engineering team to develop technologies and concepts that eventually became TILOS — a planning solution designed specifically for linear infrastructure projects.

Since its inception, TILOS has been produced by Human Dialog's engineering team. Throughout its evolution, Human Dialog transformed complex planning requirements into practical capabilities while preserving the performance, scalability, and usability that planners rely on every day.

Over the following decades, TILOS continuously evolved to address the changing needs of infrastructure projects and their planners. New requirements, ideas, and practical challenges from projects around the world helped shape its direction, leading to the release of 11 major generations of TILOS and nearly three decades of continuous innovation in time-location planning.

Supported by technology developed by Human Dialog, TILOS grew into the world's standard for time location planning, helping organizations plan and deliver railways, highways, tunnels, pipelines, transmission lines, and other complex infrastructure projects.

Today, TILOS is used by planners and project organizations around the world. Human Dialog continues to produce and evolve TILOS, support its users, advance the ObjectReef technology platform behind it, and help shape the future of time-location planning.
