During the three years I worked there, we worked on the Cape Fear River bridges near Wilmington, high rise condos at Kure Beach, and the NUCLEAR power plant near Southport. There were lots of folk looking over my shoulder, and my ass!
WE always got good results, because it was MY ASS on the line. I take pride in those results.. I can look at the results and know that I did what was necessary, not only to make money for the company, but to help make sure people were safe.
That core sample in the article is the worst example of concrete I have ever seen. EVER...
There is only one recourse for that place, IMHO. Destroy and start over. Of course, they will just continue and people maybe will die. Dead! Murdered by incompetence and thievery.
Concrete is easy to crew up. It is most often ruined by addition of too much water to make it easy to handle. BUT, concrete production is like baking. You must maintain constant control of the ingredients, and the proper placement. No doubt, they missed those classes!
I drive over that bridge regularly. Beautiful!
I did concrete testing for an engineering co. back in the 80’s. The good old boy drivers delivering the mix to the job sites didn’t care about specs and were always wanting to add more and more water to the load to discharge it quicker.
