How do I read a linear schedule?

Linear schedules can communicate more information because of the way distance related data is assigned to each individual task. The link between site and schedule information enables a quicker and deeper understanding of the construction plan.

• The distance axis is typically horizontal and the time axis is vertical  (although this can be reversed). Furthermore, the slope of the task line indicates the speed or productivity rate of the crew performing the work in the field.
  
  
• Task lines that overlap indicate possible pitfalls and show that the construction plan does not work.
  
  
• Non-linear activities, where the crew is stationary, are represented by block tasks. Examples include block valve installations, road bores or bridge foundation work.
  
  
• Restricted areas do not allow the planning of tasks in a given time and distance window because of permitting issues preventing land access or environmental issues (such as bird areas or rare plants). Clash detection highlights which tasks collide with one another.
