Actually it is two pictures. The same piece of untreated dimensional lumber is shown going from the crawl space floor to the engineered beam above. First, the column/pier is untreated and in direct contact with the crawl space soil. This provides an easy conduit for water to wick up and, worse, for termites to eat/climb up. Second, there is no plastic between the beam and the column. Third, the plastic moisture barrier is open instead of closed and/or overlapping. This was a brand new house and the builder said it was ready for ownership!
