Just a random update, I walk across the surface lot that takes up the space that DT is supposed to be built on (the block surrounded by Walker, LaBranch, McKinney and Crawford, IIRC) on a regular basis, and I noticed at least two perfectly circular holes about five or six inches in diameter near the corner of LaBranch and McKinney with markings spray painted on the pavement around them. I'm guessing these have something to do with soil samples that the builders might be taking. They probably showed up in late August/early September, if memory serves. Those who know more about the process can chime in as to what these might mean.
