From reading the comments, everyone is now an expert on concrete. I concede I don't know if this story the media is shopping is a big deal or not.
When you are in office, you rely (perhaps too much sometimes) on the experts for legal advice, engineering advice, labor advice, etc.
In addition to the City Engineer, this project was overseen by a hired clerk of the works from a local engineering firm.
There were also the design engineers. The people who placed a pillar in the middle of a doorway that had to be moved after the fact.
While a project of this size is complicated with many moving parts, it is a shame to see the facility's roll out marred by this kind of news.
Hopefully it's not a big deal and the City can move on to getting the place in use.
