I think the point that gets lost when you see comments like the GP is that they are operating under different sets of constraints because they are trying to optimize for different things.
FWIW, the govt can do "best value" contracts instead of lowest bid. But there is an asymmetry in risk to those making the selection. If something goes wrong in the design/construction, or if corruption is found, there's a lot more explaining to do. Like the old quote, "Nobody got fired for hiring IBM," except in this case "Nobody got fired for selecting the lowest bid."
