The specialist skill that's attached to drainer, is sceptic tank installation. Which I have been "head drainer" on several projects in the UK the most significant been 2 extremely large tanks on an international airport, also 2 large tanks on the silverstone Grand Prix circuit... I've been putting foul and top water drainage in since i was 18, so yes I'm more than confident that I am HONEST about the skills I have, I'm very disappointed that you would question my integrity :mad:. I can appreciate the migration system has been abused by idiots who say they can do a job but can't... In the UK a "ground worker" is a drainer and civil operative all rolled into one once you have gained enough experience. So yes I am drainer and a lot more too. The only license I will need as far as what I have read would be a white card, and I have emailed the governments assessing bodies for several states. When they get back to me with a reply I will post back on here, in hope to help shed some light on this subject. Just simply because from all the legal requirements I've read, I'd be right in what I'm saying.
I understand where your coming from, but it sounds like you don't understand the construction industry as rule.
please don't take this as arrogance, as any info is greatly appreciated, be it positive or negative.
