The industry is rife with corruption and misaligned incentives. Kick-backs are common. Bids are often not truly competitive, and when they are, people find ways like change-order abuse [1] to subvert the system. There are so many ways to rig the bidding process (bribing someone to find out competitor bids so you can undercut them) and the execution (cutting corners that you don't expect someone to find out about, or just bribing whoever is overseeing quality who might detect the corners you cut).
Even the US Army Corps of Engineers has had massive corruption cases. When I was in the industry this was an open secret, which surprising to me given the Foreign Corrupt Practices Act... eventually this would be cracked down upon [2], but as far as I've heard, still common.

It was a family business and I helped out by the managing operations (this was more as a supplier of building material to contractors) and doing business development (which involved bidding for construction projects).
Why do the same companies always seem to win?
In my neck of the woods (The Bay Area), one company seems to get all the jobs. The company's name rhymes with Gelato.
I started to look carefully at the bids.
(I got a General Contractor's license a while ago, and it an easy test, and verification of work experience is a joke.)
Ok, I looked into the owner of the contractor's license, and in all three bids, they had a "Gelato" as owner of the company.
It looks like the "Gelato" family sent three kids to Sacramento to take the test, and get their licenses.
They all bid on the same project, and one wins.
They must share the million dollar equipment, and pool of employees though?
Is it legal? I don't know.
Do I know for a fact this is how it works--no.
(There's a bill, I believe up for vote soon, in Sacramento. It requires all bidding parties to verify their company us big enough to do the project. I don't think we need a bill like this. I don't think small companies bidding on huge project to is a problem. If I am right about "Gelato" construction company--authorities should look into the bidding process. There us a reason, besides inflation, that public projects get more expensive each year, and never seem to end.)
Sometimes what looks like cronyism is just someone picking someone they trust to do the job. It can be hard to tell the difference unless there are obvious problems constantly being overlooked - like with NASA contractors for example.
Plus elaborate custom specifications for projects also make it hard to keep track of costs and bureaucrats wind-up fond of these things. Etc.
