Basic plumbing is provided either through a Plumbing Trough, that allows for plumbing to be brought in later, or basic “Stub Ups” for sewer, etc. (or both).
Plumbing Trough: A 12″ wide plumbing trough is put about 2 inches under the top of the slab. This allows room for a gray water sewer, black water sewer and fresh water to be “fished” in at any time. Then it is run through the interior partitions as in standard construction.
The advantages of the Plumbing Trough is the ability to add plumbing at a later date. Many 3rd world countries are providing central bathroom and kitchen facilities and thus have no “current” need for plumbing. However, the ability to add plumbing without the need to tunnel, or tear down walls is a tremendous value and makes the MAS™ structure easily retrofitted as future needs and requirements change. The same is true for the basic electrical system provided in a MAS™ system.
