Yes, I have found some of those sources on the website:  Apparently you were correct to concentrate on the excavation methods as the foundation seems to be very un-interesting; I was expecting an elaborate deep foundation system. Apparently it is just a spread footing cast on rock. I looked for a natural place in the article to integrate that, but I am not sure where it should go. I did, however, add a sentence from one of those sources on why slurry walls were used instead of conventional methods.  00:51, 11
