Keiler will stop and check the goblins nearest to him for valuables and items of interest, before making his way over to the walls to start looking for sliding walls and the like, checking for odd mortar lines and loose stones, tapping walls with the back of his handaxe, and generally putting his dwarven sense into it. He'll also want to check out whatever it was the chief had pushed before the balcony blew off.
(Keiler will also pay close attention to the sway of the building and any shifting noises - we don't want to be up here if the tower collapses!)
If nobody else has done so by the time he gets there, he'll also check the chief for valuables, and make sure that that wand is retrieved. Pero might be interested in it, since he's all wizardy and stuff.
