Linear Scheduling

 

 

What is Linear Scheduling?

Linear Scheduling is the collective term for planning or scheduling using graphical representation of activities occurring over physical units of work

Other commonly used terms include:

  • Line of Balance
  • Flowlines
  • Time Location/Time Distance/Time Chainage

How is it different to traditional scheduling?

Traditional CPM scheduling is typically presented as bar or Gantt charts where time is on the horizontal axis, and the vertical axis lists activities in a specified work breakdown structure

Linear Scheduling represents those activities on axes of time and physical units, where physical units can be specific sites, zones, areas, levels or blocks of work.

The physical units may also be the length of longitudinal alignment over which the work occurs.

What projects is Linear Scheduling suited to?

Linear scheduling is ideally suited to projects where activities occur in a linear method progressing from one area of work to another

Examples of such projects are:

  • Railways
  • Roadways
  • Pipelines
  • Transmission Lines
  • Tunnels

How are Linear Schedules Produced?

Linear schedules can be produced using specialised tools that in addition to traditional CPM scheduling features, are capable of developing activities using time and location axes, libraries of production rates etc.

The other option is to use data from a traditional CPM scheduling tool, and by appending additional data, use graphical representation tool (such as Chainlink) to present the linear schedule.

Chainlink

Example Chainlink Outputs

The following examples are Chainlink outputs. Programme dates are developed in Primavera P6  and are transferred into Chainlink.

Using additional information coded into P6, the transfer is seamless producing an accurate reflection of dates as often as changes to the Programme are made.

How can Australasian Project Planning help?

Preferred Method

Australasian Project Planning’s preferred method is to use Visualisaton Tools to append additional data onto existing Programmes/Schedules.

This method allows continued use of the traditional tools, and provides a cost and time effective solution in preparing Linear Schedules.

Programme/Schedule Development

Australasian Project Planning can provide selected assistance in general preparation of Programmes/Schedules for the purpose of presenting Linear Schedules.

Linear Schedule Preparation

Australasian Project Planning can prepare Linear Schedules using existing Programmes by appending the additional data, and using Visualisation Tools to present the graphical outputs

Scenario comparisons and/or progress updates can also be produced effectively after the initial programme is appended with Linear Schedule data.

Support

Australasian Project Planning can assist in developing capabilities in Linear Scheduling including Licence sales, User Training and User Support

Linear Schedules and Calendars

When presenting Linear Schedules, the rate of progress across the physical units is a key factor in representation, for example if a tunnel excavation is to be shown as progressing at 5m/day then you would expect that after ten days of work, the activity has...
