23.3.12.  Concrete day, but only Colin was there of the earlier concreting team, to direct operations. 6 cubic metres went into the shuttering on the water side of the slip and the diesel point floor. We needed the digger on the barge to hold down the shuttering in case it lifted with the force of the concrete, but all was well. We only did half of the length of the slip and will do the rest later.
