So, we're building a big house just outside Taupo and it’s got a handful of .600 x .600 concrete columns. We get the rebar in and signed off, then box and brace them all up ready to pour them via concrete pump the next morning. The pour went well and after a few days we start stripping the boxing. I'm peeling a shutter off and got one hell of a fright as looking directly at me from within the concrete column is one very dead possum. It was pressed up against the shutter with a very stunned look on its face! It must have fallen into the shutter overnight and gone to sleep until we poured a few cubes in on its head!! We all thought it was funny until the engineer came to site and made us break the column down and rebuild it. Thankfully the apprentice was a big strong fella!!!
