Utilizing Linear Planning and Scheduling for Project Control and Claims Avoidance

The intent of this paper is to provide a comparison of traditional CPM scheduling tools to linear scheduling software (TILOS) for alignment based projects. This overview described how to interpret march charts in the simplest form and then increased the complexity by adding constructability issues such as environmental restrictions and risk such as weather. The ability to represent non-linear activities on a march chart makes this a very powerful solution that enables one to view the entire project on one march chart.
Also described was the ability to apply speed and work profiles to connect the productivity rates to soil, timber or any other factor that will have an impact. Progressing during project execution is dependent on the input of the crew inspector daily report. Typically the start and end KP for each crew is recorded daily for progressing the march chart.
It should be apparent that linear scheduling software is very well suited for pipeline, road, rail and other similar projects. We have seen that march charts connect the schedule to the geography and risks of a project in a manner that is not simply possible using traditional CPM scheduling methods.
