Hi Julie,
from working with a number of customers on this subject, the question really boils down to what accounting practices are in place, and allocate based on that.
I've seen some customers that say they only capitalise or recognise the capitalisation once the costs once the project has completed, and so although the CapEx goes to projects, anything in Fixed Assets goes straight to the Towers as they are now Run costs
However, other customers have said that some depreciation costs do need to go to the projects object, but then they also need adequate information in their Fixed assets register to allow that to happen.
