The Cap Slab
After the foundation walls were completed a crew began work on the backside of the shoring wall, which included clearing debris and trenching behind the wall. After a large section had been completed and the scaffolding erected, the carpenters began laying the deck for the cap slab with the forming to follow. Once the deck and forming were complete, the rodbusters began laying the rebar. Since the cap slab cantilevers, at various widths, over the pit, the rebar and concrete must meet specific engineering standards. Even the curing process for the extra strength concrete takes up to 21 days or reach a predetermined PSI strength before the scaffolding can be removed.

It is my understanding that the Center for Health Discovery will be started after the completion the hospitals–Sometime after 2020. Of course, a lot of water will go under the bridge between now and then! As far as the isolators go, a few of them were removed on the west end to check the grout between the isolator and the base. It there was any large air bubbles, the bubbles had to be scraped out, cleaned, and refilled with grout. The specs required that the grout had to sustain a bearing weight of 1500 lbs psi. They no longer remove the isolators, they hoist and block them up above the base. I will show this in an upcoming post. Thanks for your comment on the photo. It makes a great desktop photo.
