BOM for cross country pipeline

Giving a broad framework for a Bill of Materials for a cross country pipeline is a bit impossible we don't know what you are up against.

You might also nee some civil work for stream crossings or may need to go past or underneath of other infrastructure.

Have you designed your pipe already?

For the design of the pipeline + BOM try http:/www.gwis.co.za and have a look around and maybe also download a demo version.
