When is the crew arriving at a special location?

Mission: Display the date, that a crew/activity is arriving at a special station

Sample application: A pipeline crew is working along the ROW. When is the crew arriving at the river?


  • Create a milestone task at each station you like to have the arrival date/time
  • Link the line activity start/finish to each milestone
  • Select the link option “Calculate lag by Distance tu Successor with the lag value 0. This will force the milestone nearest to the line
  • Add annotations to the milestones and set up the with tokens:

Station: {Start.Distance.Estimate}m
Arriving: {Start.Date.Estimate}

Result after Reschedule:


  • The symbol of the milestones can be set in the tab display of the task
  • The size of the milestones can be set in the tab  display of the time-distance cell
  • Station List as a Gantt spreadsheet:


How to calculate the meeting point of two lineage tasks

Mission: Calculate and display where and when two tasks will meet, that are working towards each other.

Sample application: Meeting point calculation in Tunnel construction with two driving tasks.

– Both tasks are calculated by duration  (calculation by profile is possible)
– The Quantity is calculated by the task length


– Create a finish-finish link between those two tasks
– Change the link type to “Calculate meeting point”.
– Reschedule the project.



With the “Lag” value can be defined a waiting time:
– The first task has to be arrived at this station (First is defined with the direction of the link)
– then wait the Lag time
– Then the second tasks arrives



Thames Water chooses TILOS for time-location planning of Thames Tunnel Megaproject

The Thames Tunnel Sewer is a major new sewer, urgently needed to protect the River Thames from increasing pollution. The project will upgrade London’s Victorian sewerage system to cope with the demands of 21st Century London.

Starting in west London, the preferred route for the main tunnel generally follows the route of the River Thames to Limehouse, where it then continues north-east to Abbey Mills Pumping Station near Stratford. There it will be connected to the Lee Tunnel, which is currently under construction, and will transfer the sewage to Beckton Sewage Treatment Works.

The Thames Tunnel is proposed to be 7.2 metres in diameter, about 67 metres deep and covering a distance of approximately 25 kilometres – making it one of the largest and deepest tunnels under London. Planning and design of such a tunnel brings large and complex challenges, and because the nature of the project is linear, Thames Water needed a time-location planning tool to provide a graphical visualisation of the project plan.

Channi Matharu, Planning and Scheduling Manager for the Thames Tunnel, started to look at linear planning software that would allow him to validate the schedule and have good presentation capability. After reviewing available systems for functionality and ease of use, the project team chose Linear project’s graphical time-location planning tool, TILOS, for its flexible drawing software and scheduling ability.

“We needed a tool that would extract the very detailed information out of our planning software and give us a visual representation that would reflect the scale of the project. We looked at a range of linear planning software tools, and following a demonstration by Asta Development we chose TILOS. TILOS can condense 60 pages worth of crucial information into one page. We need that level of detail presented as efficiently as possible,” said Channi.

TILOS is a very powerful tool

There are many challenges to consider when planning such engineering projects, many of which will not be visible or manageable when using CAD and Excel software tools. Unlike these systems, TILOS provides a graphical visualisation of the project plan with the project location.

The process involves preparation of the project programme in P6, checking it through for logic and consistency; it is then exported to TILOS. TILOS verifies whether the logic is right – whether the tunnels join in the right places, whether they are continuous and so on.

The data is displayed in picture format to the project team. This illustration of the critical path helps ensure, for example, that the construction of the shaft will be complete before the TBM is ready to begin boring the tunnel at the site. A picture shows this more clearly compared with conventional planning software. All the constraints are highlighted and any anomalies can be put right and re-exported.

Clarity of information means good communication

TILOS allows the team to identify and extract just the right amount of information and exports the detail needed.

 “Using TILOS means the whole team has visibility of the plan – they find it easier to follow than a bar graph. In TILOS an object relates to a physical representation, whether it is a shaft or a tunnel,” continued Channi.

“TILOS is making our lives easier. It helps us to sort out any issues of logic before they become a problem. It also allows us to communicate clearly to all teams involved exactly what we are aiming to do and is a good tool to demonstrate to all stakeholders what we are going to deliver.”

Channi and the team members who use TILOS have found that it gives exactly the output they need. Its success means that the team is keen to implement TILOS in a much wider community.

“My goal is to have my full team trained on TILOS and using it going forward. We showed it to the wider project team, and thanks to its strong presentation capability, it will be used for the duration of this project.”

This proposed engineering megaproject will be presented for planning consent in late 2012, with construction beginning in 2016 for a period of 6 to 7 years. The Thames Tunnel will upgrade London’s Victorian sewerage system to cope with the demands of 21st Century London and will tackle the problem of overflows for at least the next 100 years, enabling the UK to meet European environmental standards. TILOS will be instrumental in making this great project happen.
