Understand Activities

Activities are the primary way you represent construction activities in your project. For continuity and efficiency, you create new activities by selecting an activity type template and then placing an instance of that activity into a time-distance view. Once you have added an activity, you should review and edit its properties to make sure it represents the correct timing, location, and work to be done. You can also annotate activities to make the chart easier to read.

For each activity template, you can also specify a default summary activity to which new activities will be assigned. Then when you create a new activity, the summary activity is automatically expanded in the view to accommodate the child activity. This also works if the summary activity is collapsed. When you create a new activity, the summary activity is automatically expanded so you can draw within it.

Activities can be entered into a view with time-distance cells, drawn within Gantt chart cells, or entered directly into a sub-project within an Activity list.

There is a library with activity templates for showing activities that can be used or you can edit the display directly on the activity within the view.

Operations within a sub-project are displayed with the activity object. Several activities can be linked together and the generated schedule can be calculated.

A group of activities can also be summarized as a total in order to receive a structured process. Activities can be displayed in time/distance cells and in Gantt chart cells.

Additionally, to the visual display in time/distance cells and in Gantt charts, an activity can have allocated costs and/or resources in order to evaluate these in histograms and resource plans. An activity process can be saved as a baseline in order to compare the differences between the planned and actual status. Using the progress function, the most different methods of an actual status to a certain date can be ascertained for an activity.

Snap Grid

A snap grid is used for the graphical creation and editing of Activities.  On the Main Toolbar, you can enable a snap grid aligned with the time and distance axes to which Activities will snap. The defined grid lines can also be used here as snap grids. Configure the snap grid in either Tools > Options > Snapping or in the Properties grid dialog box.


Objects can be deposited on different layers in Tilos. Enter Layer in the Project data > Graphic Library > Layer that will then be assigned to an activity. These layers can be hidden and shown with a view.

Create an Activity

Activities can be entered into a view with time-distance cells or drawn within Gantt chart cells or entered directly into a subproject within an Activity list.
