We have an old, previous telecom use I believe, concrete building at a remote site. I am considering re-purposing the building and am curious what information I could acquire from you. The building number on the tag is: 21028 and it appears to be 20' wide by 12' deep.
It previously had 2 AC units, which previous vandalization had the holes boarded up. it also appears to have had 4 lifting lugs, now ground off, on the front and back sides. 
Thanks,
Rob
