Is this the kind of stuff you are looking for acid???? Im afraid you will have problems with copyright mate. Every set of plans I get for roads/pipelines etc are usually copyright and are covered by those laws. If you do get some you will more than likely have to engage them and ask for permission to use them.

I have given you links to my dropbox....one is a PDF with no such copyright on it (though it may still be) and a plan with the copyright on it so you know what to look for. Be aware even though there may be no copyright warning on it mate...it may well still have it...so this might be a grey area. Designers basically are like artists and their work is usually protected. I will have a scout around and see what I can find in the meantime mate.
