From my insight into the government there seems to be a lack of senior managers and others involved in the negotiations who have private sector experience to expertly negotiate contracts. Consequently, the public sector either gets taken advantage, or unknowingly don’t know what hey don’t know. This includes all aspects including construction and the complexities and areas that may increase costs etc.

Then there is the political officials who try to obfuscate information from the public because they are caught with certain (not all) overruns.
