Hi all, I'm being asked to determine whether or not a proposed profit of 10% is fair and reasonable on a sole source T&M contract we're planning on awarding. We haven't done this type of work before and I don't really have anything to base our decision off. I've read through FAR 15.404-4, The Time-and-Materials Contract: The Time Has Come for A Long, Hard Look, the DoD's weighted guidelines, and GSA's structured profit/fee approach and it doesn't seem like 10% is even close to something that should be fair and reasonable considering the contract type and risk involved, though I understand there's other factors to consider. GSA's GSAM says that only fixed price contract should be towards the high end of the profit range which they max out at 7%. I was also looking at the link below (table starting on page 18) where it appears to recommend a profit of 0% to 1% for a T&M contract.

Am I off base in my thinking that 10% doesn't appear to be fair and reasonable at first glance for this type of contract? I was thinking, considering the factors in the GSAM, that a high profit objective for us should be closer to 3% which is leagues away from their proposed 10%. Appreciate any insight anyone can provide, thanks!
