One of our client is doing a high level of value engineering and expecing significant savings by changing the piping material from back steel to HDPE. Instead of connecting landing valve directly from the alarm check valve riser, the standpipe will connect to the external fire ring main made of HDPE piping and from that ring main, connections will be provided to the fire hose valves inside the building at the perimeter. By this arrangement, they dont have to run lengthy balck steel pipes inside the cargo terminal which will provide them significant savings. Please refer to attached sketch.
I have not seen such type of network anywhere bu technically, I think there is not problem. Appreciate if anybody can advise me the feasibilty for such network.
