In terms of the progress, this is typical for a concrete building that has 3 levels of rakers (internal bracing). There is a very methodical process that must be followed when excavating/bracing in a situation that is similar to this. Once the bracing is complete, and the building has "bottomed out", then it will still be a slow process for the actual lower floors to be placed around the bracing. Please keep in mind that the reason the core was placed in the first reason was to "kick" the exterior sheeting to a location where the loads can be transfered across the job.
