NEC ECC: Under an Option C contract, does the defined cost of "Equipment" include costs associated with repair and maintenance?

The SCC sets out how equipment costs can be claimed depending on how the equipment has been procured, i.e. external hires or internally owned equipment etc.

Are general repair/maintenance costs which are not included in any rates allowed under the Defined Cost submission, for example the "Off-hire" charges associated with a site vehicle which includes replacement part charges etc?
