The New Metro Line B in Rennes contains a big viaduct. It is build from Eiffage and planned with TILOS.

  • Total length : 14 km
  • Tunnel Section : 7,5 km
  • Viaduct : 2,8 km
  • Stations : 15

How to prepare a Primavera Schedule for Exporting to TILOS Time Location System

Following a description of the most basic preparations on a Primavera Schedule, when you intend to transfer this Schedule to TILOS and display it in a Time-Location-Diagram:

Promavera To TILOS

A. Additional Data Fields

Some additional information for the activities has to be edited in the Primavera project:

  1. Location information
    Each activity needs to have a Start Location and End Location value. Those are needed to display the activity along the location axis and this is displaying the working direction too.
    Preparation: Create User Defined Fields (Text) named StartLocation and EndLocation and insert the corresponding values.
  2. Display information (Colors and shapes)
    In the Time-Location diagram a task cannot only be displayed in one fixed way: They can have different shapes (e.g. lines, rectangles, parallelograms), linestyles and color. Those graphical characteristics are in TILOS controlled by the object “template”.
    Preparation: Create a User Defined Field (Text) named TilosTemplate and insert for each activity a value (e.g.”pipe laying” or “concrete work”): All activities that should look the same in TILOS get the same value.

B. Activity Filter

Preparation: Create a Filter that selects all the activities that you want to transfer. You may create another User Defined Field (Text) named TilosExport and set a value when the Activity should be exported.

Think about Structures, Summaries and Granularity:
Is the Time-Location diagram showing all details or is there a different Granularity? E.G. Some Buildings/construction elements can be displayed by the Summary activity only. In this case Summary/WBS activities or level of effort activities has to be created.

A Skyscraper Remodelling Schedule – displayed in Time-Location-Diagram – with TILOS

Still an unusual sight, but why not? Here we present an example of how to display a Skyscaper-Remodelling-Schedule in a Time-Location Diagram.

The vertical axis represents the levels / floors of the building. Alongside this axis the map of the skyscraper facilitates the connection between activities and level/location of work.

The horizontal axis represents the time axis.

As a result there is a chart, comparable to a standard Gantt view – but enhanced with the location dimension.

The tasks are mainly displayed as ribbons or lines. They represent how the different crafts are moving trough the building. An overlapping of ribbons indicates that different crafts are planned in the same location at the same time.That may be a clash.
The horizontal distance between two neighboring crafts represents the “buffer” between them.

For sure TILOS can add cost and resource information along each axis: Time and distance.



The new coastal Highway in Reunion Island is planned with TILOS

The New Coastal Highway will be about 13km long. The Highlight of this connection of Saint Denis and La Grande Chaloupe is a 5400m viaduct along the coast cliff – a bridge over the water surface. It will carry 2×3 traffic lanes. Two of them will be reserved for light and public transport: Buses, pedestrians and bycicles.
The viaduct is needed because the existing cliff road suffers from rock-falls and floodings caused from tropical storms. It will keep a safe distance to the cliff.

The Viaduct cost about 715 million Euro. Most of the structure will be prefabricated on land and the installed by sea.
Two other packages icluding heavy earth movement and earth works cost about 530 million Euro. In this area TILOS will be used.

The project will be completed in 2018.

TILOS Task Calculation Part 1: Linear calculation models (Video blog)

This video blog / tutorial is showing some easy linear calculation models, that TILOS Linear Scheduling system uses to estimate task durations.

This is the start of a series of videos regarding TILOS task calculation.

This time:

  • Determining the Work rate = Quantity / Duration
  • Estimating the Duration = Quantity / Work rate

Webinar: “Using TILOS for Planning and Execution of a Pipeline Project “


December 17, 9:00 AM by GMT
Duration: 40 minutes
Registration URL:


Major pipeline projects face many challenges that are not typical in facility constructions. Land acquisition, seasonal construction issues, environmental restrictions, major crossings that involve HDD’s (Horizontal Directional Drills) and optimizing workface planning are key considerations. The goal is to keep the construction window as short as possible to reduce the overall cost of the project to the owner, while understanding all the key interfaces points on the right-of-way. This presentation will explore the advantages of using the linear project methodology to create a baseline and to report on progress. TILOS is a visual planning tool that serves as an excellent tool for collaboration between all the major project stakeholders.


• Challenges of Pipeline Construction
• Why use Linear Planning Methodology
• Examples of Pipeline projects
• Progress and Reporting in TILOS
• Using TILOS to integrate construction challenges
• Questions and Answers

Presenter Details:

Lorne Duncan – Managing Director of Linear project Americas Inc.
He has extensive experience in pipeline planning in North and South America. For several years he was the Senior Pipeline Planner with the Enbridge Pipeline Construction Group and has worked for many pipeline owners, engineering firms and contractors to develop baseline schedules, bid schedules and has used TILOS to track and optimize the execution of the project once construction has started. He continues to work extensively as a consultant for pipeline planning for many organizations in several countries.. (802)

Have you ever asked yourself how to display an infrastructure project in a Gantt diagram – in a proper way?

Location based Scheduling is the main target of TILOS – Time Location Scheduling.

See below a Gantt Diagram structured by Location coming along with the correspondent Location Maps – converted from a Time-Location-Diagram.

New TILOS Version 9 is presented at InnoTrans 2014 in Berlin

On many construction sites in Europe and all over the world TILOS has successfully proved on minor and major construction projects.
The development goes on and Linear project will present TILOS 9 for the first time on the InnoTrans fair in Berlin from September 23 to 26 2014.

The major goal for the version 9 release is: Improving the methods of structuring projects and their visualization.

Task Grouping is displayed in most Gantt chart based systems using headlines and summary tasks. A direct link to the location is not possible. Grouping in TILOS can display coloured vertical ribbons with graphics attached left to the text panel. The location is includes in such charts and this improves the understanding an communication of work execution.

The task boxes can be formatted with text, logos (responsibility) and traffic light indicators similar to the cards in planning tables.

The same project structure now can be visualized also in the time distance diagram by using WBS or category summary tasks. Those are calculated from the task categories or WBS. The time and the distance coordinates of the detailed tasks are summed up to the structure above. This is ideal for displaying top level plans from detailed data set.

The detailed activity data can be imported from Primavera, MS Project and ASTA Powerproject with all the structures included. Only the graphics for the WBS or category nodes have to be assigned as well as company logos for the executing companies.

The new pure location links in TILOS 9 allow to set distance coordinates based on links in a similar way to time coordinates during the reschedule. Planning locations is then much easier and more flexible now.
Example: One driving task in a tasks group (process) can define the distance to work on both: Predecessors and successors.

The full list of all functions of TILOS 9 will be published soon.
