Hello,
on one of the project schedules i am working on, they want to have not only the construction costs but also all other type of costs such as company overhead, design stage, procurement contingency etc distributed over time as well.

to approach this task do i just create independent activities called overhead or design for instance and enter them in to the schedule or do i need to create a separate summary schedule - this is going to upper management of that company so they only care about main distribution of costs over time, not how individual construction trades distribute

so as a result i need to include non work scope items into the schedule to show it together with the real construction scope items in the schedule.

how do i approach this situation?
