“TILOS was developed by Linear project to improve visualisation of repetitive tasks when planning and managing major projects. The time-distance diagram supports all highway, rail, tunnel, pipeline and bridge projects.
The key benefits of TILOS are the flow of visual data in terms of time and place on one plan. Gantt charts/CPM schedules and network diagrams are more analytical, but they fail to provide a visual connection between the project plan and the project itself.
TILOS connects the geographic information of the construction corridor with the schedule showing what is built where and when. Due to the lack of decent software tools, many plans were drawn with software packages like CAD or Excel. The major flaw being that as soon as changes occurred, plans were constantly being amended as there was no easier way to process the data visually. TILOS combines both time and distance in one powerful project management tool:
The main difference between time-location planning and standard Gantt chart planning is that time-location charts are two dimensional. Along one axis is shown location of the work, with the time element being illustrated along the other. This makes the system perfect for planning work on linear projects, where the work follows a geographical line.

Templates for road, rail, pipeline and tunnel projects are included when you purchase TILOS. By clicking and dragging the line, the system will quickly show you exactly where on the road, rail, pipeline and tunnel construction you should be working on at any point in time.
