Depends on whom is responsible for the issues. If the Owner was negligent in some way they get the costs. If it's the P3 consortium, it's on them. If the city is weak and accepts the burden, then yes they're to blame for being weak.

SNC and their constructors (SNC would likely work for the constructor, but I'm not up to speed on that project and who is financing it) are no different than anyone else. They're in it to make money. On large jobs, there are always claims, court cases, etc.

Again based on my experience in Winnipeg, the City will tell you to pound sand unless they have meddled in some way and legitimately will pony up the cash. There has been very, very little of that on BRT. As the City says, they've used virtually none of their contingency.
