Does it anyone know when the transistion from Pier&Beam to slab started in Dallas ? I generally see the transistion was about the late 50's with both types being built into the 60's. I know there are exceptions but I mean generally about the time when Slab started to overtake Pier and Beam as the favored construction method. Also, curious to hear others opinion on what were the causes that lead to the change over from Pier and Beam to concrete slab ?

Thanks
