Re: Floors?
At my university, the building mainly housing the Computer Science department had a lobby with a parquet floor which the IT students installed. (The floor may have been their gift to the school - those neurons were recycled decades ago.) After inserting the final piece of the puzzle, the tired crew went back to their dorms, only to return the next morning to a veritable explosion of small wood squares. It seemed the kiln-dried lumber had made merry with the rise in humidity overnight and expanded a bit in size, but the walls were not so forgiving. Reportedly, the student crew had to hand-sand each of the thousands of squares to make them fit once again. (I suppose the grain of the wood made them no longer square so the pattern wouldn't work if used as-is.)
