Yes - the legislation itself needs ripped up and replaced with common sense procurement that follows industry norms.
As someone who bids for these contracts, my outsider view of the procurement process is that it seems to spends so much time and effort being fair and impartial, that it actually ends up:
* Giving too much information to suppliers (i.e. who else is bidding and how much the government will pay) - These things are never given in private sector contracts but you are often told with a public sector procurement process.
* Being a checkbox excercise, with scorecard criteria that can tip the balance that don't have anything to do with how well the company actually does the job.
* The procurement process itself can say to companies 'we are hard to deal with, uncooperative and don't really know what we want', which will obviously influence pricing. I've seen tender documents say silly things like you will be disqualified if you can't make an in-person meeting about the tender given 24 hours notice. Tender documents often contain 49 pages of waffle and almost zero specification of what is actually expected to be delivered (while this is common in the private sector too, it's much worse in the public sector in terms of how poorly defined tenders are).
* Often they have classic procurement footguns, like mandating cost down initiatives throughout the contract which everyone on the sales side knows means 'build in extra margin in years 1 & 2 to fake cost down to year 3'
* The process is so 'fair' that it ignores who will actually do the job for the best total value (mix of quality and cost). This is maybe a little subjective, but often you can end up with what appear to be bizarre awards from an outside perspective.
