Tilos 10.2 is now available!
Work Phase Assistant
TILOS Work Phase Assistant in an embedded add-on module for managing the complex logistics
of linear projects. The addition of Work Phase Assistant replaces and expands upon, the Rail
Assistant functionality that was previously only available in the German market. Work Phase
Assistant (WPA) is used to create ‘maps’ that graphically show segmentation and progress of
construction, along with the related tasks. The WPA also helps you create and leverage track,
road, and other possession calendars to optimize phase management and task positioning.
The WPA is enabled by a Work Phase Assistant Interface (WPA) license, which can be seen by
selecting Help > License Manager. If you do not have an active WPA license, the associated
functions are disabled (greyed out) in TILOS.
WPA Functions and Workflow
Using the WPA, you can do work phase planning, which lets you schedule work and watch
progress for the phased construction of rails, roads, pipelines, transmission lines and more.
(See Planning Phased Work with WPA in the help.)
New WPA functions enable you to:
1. Configure one or more 2-axis distance cells (X and Y axes can each use separate units,
such as m, inch, track number, etc.), and then synchronize the cells by making one or
more master cells and then some dependent cells.(See Setting Up a WPA Project in the
2. Insert an area map of the site where phased construction will occur into the 2-axis
distance cells. (See Inserting an Area Map in the help.)
3. Import tabular data of the X, Y coordinates of important features on the site, such
as the start and end of road, rail, pipeline, or transmission line segments into the 2-axis
distance cells. These could also be the coordinates of features such as road intersections,
rail stations, pipe joints, or towers. Import this data into the 2-axis distance cell with your
area map. Add scales and grid lines in the time-distance and 2-axis distance cells to
delineate the construction phases and other (See Setting and Importing Up Tabular
Feature Data in the help.)
4. Add tasks for the types of work to be done (ideally from a predefined task template)
in each construction phase for each feature. Then link these tasks to create
predecessor/successor relationships. (See Adding and Linking Tasks in a Time-Distance
Cell in the help.)
5. Create both working time and non-working time task and resource calendars out of
grouped tasks in a Gantt chart, and apply them to your work phase plan, e.g., as track
possession calendars. (See Creating Calendars from Grouped Gantt Chart Tasks in the
6. Create any additional point and line features that are needed to complete the
network of track, road, or similar features inside the 2-axis distance cell. (See Inserting
Point Features and Line Features in the help.)
7. Import symbols and images that will visually enhance the presentation of the
features (representing real-world objects) and their construction phases and statuses
into the area map. Creating symbols in TILOS, exporting them, applying them to your
tabular data, and re-importing the data is an efficient way to do this. (See Exporting and
Importing WPA Symbols in the help.)
8. Connect the features in your object network to tasks . Configure these features as so
you can see their task progress graphically in the distance cells. (See Linking Features
with Tasks and Showing Progress in the help.)
9. Optionally, create groups of ‘time-dependent’ images and/or symbols that are
associated with different stages of progress and connect these groups to the features in
your work phase plan to help you better visualize phases and task progress. These WPA
Groups can be saved as templates in the library for re-use. (See Setting Up WPA Task
Groups, Representing Features as Groups with Progress in the help.)
XML export/import – An updated XML exporter/importer allows you to exchange a
richer set of data. This enhancement will help you when you need to revert to an earlier
TILOS version, such as going from version 10.1 MR 1 to version 10.1. The new, more
complete exchange profile includes all available tokens. (See Support Note – Exchanging
Rich Data via XML in the TILOS Community.)
Printing – Gantt charts can now be printed using the same Print pane interface and
settings as printing integrated views and others. (See Printing Gantt Charts in the help.)

● When you adjusted work rates and quantities in a task template, it was not updated in
tasks using that template. Even when selecting “calculation” while updating all tasks from
a template, the work rate did not change. Now it does. <LPN-40702>
● You could not select a template for a new task when the task was currently selected in
the Gantt chart.
● Scheduling was incorrect when Finish to Finish links existed between tasks with different
calendars and end dates before a weekend; the successor´s end date was earlier than
the predecessor´s end date, even if it had a Finish to Finish link with an additional
positive time lag. In network calculation (rescheduling) it is not possible that a successor
has earlier dates than the predecessor if there are no negative lags.
● After locking more columns than available to show on the screen, you could not lock
right columns in a Task List view, resulting in a corrupted view and the loss of horizontal
● You received an error and could not import mass haulages from Trimble Business Center
when multiple haulages existed between the same areas.
● When you filtered tasks based on certain start dates, tasks that should have been
displayed were not.
● French interface text that contained accented letters was displayed with unusual
● TILOS files were corrupted when you lost network connectivity. (See also Support Note –
Recovering a Corrupt Project File in the TILOS Community.)
● Haul distance was not being automatically refreshed when mass balance points were
changed. You had to select the cut or fill area manually again to update the haul
● Categories were not imported correctly when you used the Microsoft Project XML
importer, for example, if a task had multiple selections for the same category path, only
the first value was imported.
● You could not select the Speed token for import/export in sector profiles; you could only
enter it manually. The Speed token Speed is no longer available for new sector profiles.
● You could not drag-and-drop graphics files from Microsoft Windows Explorer into the
main graphics cell (0,0).
● You could not import/export into a mass haulages list using the clipboard: No changes
appeared when importing changed data and no new entries appeared when importing
● Values in histograms did not show the correct sum for tasks in the past.
