Back in 1978, I think it was, my company contracted to excavate for the new Capitol National Bank. It was the largest job that of that type that Lewis Contractors had ever taken on. Considering it was excavating 30′ deep a full block square downtown Austin from 7th to 8th St. between Guadalupe and Lavaca and it was solid limestone rock it had its challenges.

The only real way to accomplish a project like that was to blast. If I remember correctly, we did it in around 60 days. Considering the equipment we had to work with in those days, seems remarkable to me now. It all came off without a hitch.
