Federal Money projects all have a change clause that uses Part 31 Federal Acquisition Regulation ("FAR") 48 C.F.R. Part 31. Do those projects have a standard or required % for Mark-ups for change orders? - I have been looking at a contract that refers to that Regulation, but have seen no "allowable" mark-ups in either the regulation or the contract. Is that un-usual? Is there a mark-up on Federal projects? I think there are some general one's in legal claims but I do not know where those come from.
