At what point of our work are we required to hand it over to a tradesman? I don't want to hand it over too soon or too late. But I accept that too soon is better than too late.
When you do your owner builder course, you should get a manual with detail steps listed. I done the course from TAFE and it's quite helpful.
The manual won't go through such details as you mentioned either though. It's then up to the tradesman you deal with, and your understanding of the whole process.
If you found good tradesman, you will be clearly told what things are covered and hopefully details in writing. They will also remind you things you might have missed. Also, most tradesman will have contacts in other areas and will be able to provide help/other information.
The biggest problem to watch out is, due to unclear instruction or because there's something you are not aware of/missed, someone stuff up something. There will then be dispute between you and the tradesman, or even multiple of them, everyone pointing fingers at each other...
Normally for people like me who don't have enough knowledge of the industry, we leave it to the project home builder. Doing it yourself can save the 25%+ margin they charge on top of everything. But you have to pay the price to handle all these hassels, like a complicate project management. And don't forget it's very expensive. we are talking about hundreds of thousands of dollars here.
I read posts about nearly finished houses with windows/garage door broken/damaged by kids, or things delivered got stolen. The builders got insurance covered. What if this happened to you?
I did try to do owner building after I finished the short 2 day course. But after hearing/seeing so many bad stories we decided to start with project home first and see how it goes.
Personally just think it's a bit risky to do it yourself if you don't have enough knowledge or support from other professionals.
Hope this helps...
