Here are some photos of hollow core installation taking place this morning before the rain came.
Notice here that the rebar used to tie the floor system into the wall is a 90ยบ rebar that turns up rather than down into the wall. This makes the placement of this reinforcement far more simple than if it were required to come up out of the lower level wall. It is nearly impossible to either bend the rebar precisely in between planks being laid, or to navigate the planks into place around a fixed piece of rebar. There is almost no way of knowing the layout of the planks and placing the rebar appropriately according to that layout beforehand, so simply installing them when the grout between planks is placed makes for much faster assembly.
