From the OP bcos you fckers aren't going to look on the link... Davis-Monthan Air Force Base in Arizona is the largest aircraft storage facility in the world. please log in to view this image
It's a two story RC frame basement. There will be a new faculty built in top of it in the next phase, were not doing that section of it. Ten meter excavation into limestone, a local planning condition restricts the height of the final build so they went down two floors.
Two floor basement, bloody hell. So will outside ground level also be brought down that low. Looks immense tbh. What will it be a faculty for.
