I'll say it's absolutely salvageable. I can say it looks like a needlecast disease, with the old needles browning and dropping, a lot of the new growth intact. Although this is really not common on concolor firs; concolor firs, are generally pest and disease free, why I'm skeptical it's diseased, but it is a possibility, as they're effected by a few fungi:

Example: https://www.canr.msu.edu/news/concolor_fir_turning_brown 

I would strongly suggest submitting a plant sample to MSU, taking multiple entire twigs, in various states, put them in a box and send to MSU for the lab to get a positive ID on something if anything.

In the meantime, all that can be done is blow out underneath it any fallen and potentially diseased needles and dispose of them. 

 I'd also suggest refraining from watering it unless we're in a prolonged drought period as root rot is always a possibility, and excessive water will only contribute. 

And know that even if it is infected with a fungal disease, nothing can be done until next spring, in which preventive fungicides can be applied to protect the new and existing growth. Fungicides are effective for this, and the tree can make a full recovery. 

Best of luck.
