There is no specific CAS guidance on “…overhead, office expenses, operational expenses, and General and Administrative expense allowable and allocable to travel…”.
It is a matter of negotiations.
9904.405 Accounting for unallowable costs. 9904.405-20 Purpose.
(a) The purpose of this Cost Accounting Standard is to facilitate the negotiation, audit, administration and settlement of contracts by establishing guidelines covering:
(1) Identification of costs specifically described as unallowable, at the time such costs first become defined or authoritatively designated as unallowable, and
(2) The cost accounting treatment to be accorded such identified unallowable costs in order to promote the consistent application of sound cost accounting principles covering all incurred costs.
The Standard is predicated on the proposition that costs incurred in carrying on the activities of an enterprise—regardless of the allowability of such costs under Government contracts—are allocable to the cost objectives with which they are identified on the basis of their beneficial or causal relationships.
(b) This Standard does not govern the allowability of costs. This is a function of the appropriate procurement or reviewing authority.
Travel cost might be treated as an:
(a) Other Direct Cost (ODC) in which case G&A and profit could be applied or
(b) Made a separate CLIN with no charges (overhead) or profit applied
However, the contractor wanting to apply:
o office expense,
o operational expense and
o G&A expenses (and I assume profit)
to travel cost is a bit overkill, excessive, multiple and duplicative charges.
A G&A expense is any management, financial, and other expense which is incurred by or allocated to a business unit and which is for the general management and administration of the business unit as a whole. It does not include management expenses whose beneficial or causal relationship to cost objectives can be more directly measured by a base other than a cost input base representing a total activity of a business unit during a cost accounting period.
Please consult with your agency, Center for Disease Control, (CDC), contracting offficer and legal counsel.
