The plumbing can be seen in the background, with the exposed ends having PVC safety caps on to protect it from external elements entering the pipes; this avoids blockage of the pipes. All plumbing is placed within close vicinity of each other, thus allowing easy connection and reduction in cost. Temporary fencing can also be seen in the background, which by law should be surrounding the entire construction zone. There is compressed crushed rock that has been laid out, which the concrete will be poured over after the TM has been placed, the compressing machine is also seen in the background.
