Hi, wholesomefolsum
from me too!
Danged contractors, they can really be aggravating. Your story brought back memories of eight years ago when we had our pool and deck refinished. Even after asking them to please be as careful as possible, the workers trampled plants and even washed out their cement buckets on the side of the house, leaving white stuff all over the foliage of rose bushes and other shrubs ... and even my tomato plants! When they were finally finished with the job I went around the yard and found they'd left trash and chunks of cement behind the shed!
I swore that the next time we had contractors doing any outside work, I would put up a very large sign saying:
ANYONE stepping on, crushing or damaging plants in ANY manner, is subject to be COMPOSTED!
Remembrance plants are always special to us and from the photos you've shown, your plants don't look like they were damaged too much so I do hope that they recuperate. I don't know a thing about growing Hen & Chicks, only that we have some real beauties in our database:

We have lots of members who grow Semps so if you ever want to know more about those lovely plants you should check out our forum specifically for Hens & Chicks:
