I know that we've already covered fires before (Yes, I'm looking through old postings for info, but I have a co-worker who wants me to post the specifics of this case.) Very old unreinforced brick wall building (perhaps two wythes). Similar brick building next door (air gap 1" or less?) burned down. Planning on demoing wall of building that burned down and then taking cores of wall on store that did not burn down. The inside face of the wall of the store is painted in places. This paint did not peel. The mortar was checked by scraping and prodded with an awl. On the portions of the wall not next to the burned down store, the mortar had a very light whitish color and did not scrach off easily. On the wall next to the burned down store, the mortar on the inside seemed fairly sound, however it was easier to scratch off material than on the other walls. On the outside portion of the wall (at an elevation above the burned out neighbor's wall) the mortar was whitish in color, scratched off readily, and could be penetrated by direct pressure with the awl point. The building has a wood framed roof and probably lacks a contemporary seismic tie system. Anyone have any insight, suggestions, evaluation criteria, et cetera Thanks Stan Johnson BS, EIT, Please excuse the doozie of a spelling blunder on my post early today. :, -(
