Work continues on the rotary parlour pit in the Milk Harvest area. The brackets mounted in a circle support the rollers for the rotating deck. Stairs in the centre provide access from the Mechanical Room to the Parlour Pit. The pit itself is constructed in small increments – foundation, half of the walls, gutters, floors etc. as there are many services that must be installed in stages. Concrete slabs are poured over a polyethylene vapour barrier, which controls the rate of curing of the concrete, provided a harder surface in areas where cleaning agents will be used frequently.
