"Concrete exposed to temperatures greater than approximately 570°F often turns a shade of pink, associated with chemical changes of the iron-containing compounds in the aggregates and paste matrix. At much higher temperatures—which are not commonly encountered during typical structure fires—the concrete can turn back to a light gray and then eventually to a yellowish-brown color. Concrete that has turned pink is damaged and should be replaced."

My engineer brain couldn't resist looking it up!

A different feel to this chapter - because the family is involved, rather than the crew?

We have a builder friend who built his own house, lost it in a house fire, and rebuilt it again himself. He just "moved forward", where I think that may have destroyed me.

An interesting take on a historic event!

Your jarring visit back to the homes you worked on that were no longer there reminded me of a sad trip I made to the SFO Bay Bridge after the old Eastern Span had been demolished in favor of the shiny new suspension bridge. I spent two of my peak years crawling over that 1920’s metal structure in the cold and wind and fog and it was just gone. It became plain to me then that very little is permanent in the world of men.
