Trust me. There is no need to be concerned.
Here is a pretty thorough Intimidator construction gallery (with dates!), just for when these types of questions are asked. Again, all credit goes to Wormy for organizing the gallery and making it look pretty for the website. I'll take
some credit for the photos.
It looks like re-bar for the first footers went in early July, and the concrete for the footers was being poured in late July/early August.

And just for reference.. here is Nighthawk construction from May 17, 2003 -
