Indirect costs and associated expenses?

Hi All,

Our schedules do not include indirect activities and costs like any crane works etc. as these do not earn value. What is the best way to capture and store these costs associated with direct activities so that later on, these will be considered in EVA studies?

Is it expenses where we add these costs to certain activities? if not, how can we best use expenses for this purpose if relevant.

Would appreciate if you can advice,
Cheers.
