Also, one of the major things that has happened through this process, even though we are recom- mending the higher bid, is something called "holiday testing." He explained that Jacksonville experienced some significant problems in the application of the interior coating that goes on ductile iron and had to replace a large amount of piping.

Director Pinto felt Commissioner Scurlock has explained the situation very well. The difference in the structural integrity of PVC pipe and ductile iron pipe is about 7 to 1 in favor of the iron pipe, and there isn't any question that in running along the railroad, there is a concern about the vibration that would take place. With the experience of only 6 years in the ground with the large diameter PVC pipe, he would feel uncomfortable recommending it in this situation, but assured everyone that we will consider all materials in the future in direct relation with the project itself.
