Two steps forward, one step back?

Today they did some more electrical work, as well as installing the wiring for our alarm and smoke and carbon monoxide detector systems (take 1 step forward). Here is what the alarm panel will look like in the closet for the master bedroom (is it just me, or is the alarm for our house going to look like those alarms you see in restaurants with all of the blinking lights?).


They also managed to get the shower and tub for the master bathroom into place (take another step forward).


Unfortunately, in putting up some more light sockets, it appears that they had to move around some of the HVAC ductwork that had already been put into place (take one step back). (Yes, that is a duct hanging down into the middle of the breakfast nook -- I guess with that hanging right over head, our breakfast area will be toasty warm in winter and nice and cool in the summer!)


By the way, while I don't claim to understand much of the construction process, I did learn today why it is so important to get those walls up on the house once it is framed... Otherwise, there would be no place for the poor construction workers to do their long division!
