How to consider own equipment cost for specific project?

This section presents some useful information for estimating the cost of control equipment.
We must recognize the cost includes the following components.
· Purchase · Transportation from supplier to user · Installation and documentation · Calibration · Maintenance over the equipment lifetime

I know is that it will be unfair to consider entire equipment cost under single project.
What I suggests, we can put transportation to project site, repair, maintenance which might occur during usage of that equipment for that project.
Otherwise, cost of purchase (ownership) should be excluded and should be considered as depreciation for a company as a whole.
And above equipment costs (repair, transportation, etc) will be direct costs.

when higher cost and capital requirments prevail, we always consider alternatives such as equipment swap or lease/rental.

purchasing equipment for a single project is some how problematic as it holds alot of expenditure areas,carrying costs,running costs,and equipment desposal at the end of the project.

Simply, The cost of purchase will be a assist for a company.
the projects will cost by the depreciation "annual percent".
and the cost of (repair, transportation, fuel, etc) will be direct cost to the projects.

using project costing and charging depreciation based on % of usage under indirect fixed costs

deperciation charged for that period in which that equipment is used in the project

alternatively

value of asset when the project start                               xx

value of asset when the project closed                         ( xx)

amount charged in the project i.e deperciation                xx

Charge cost of depreciation to the project

Depreciation cost per hour
