So your BIM would give me a detailed list of materials, time and costs and then a predicted resale value for the finished dwelling? I would then be able to apply for a owner builder loan or claim depreciation if I choose to use it as an investment.

Looking to find the price people have paid to have a quantity surveyor report done for a owner build residential dwelling. Just so I know what to expect. Thanks

Having said that we still talk about squares and acres

How do you get your timber certified? Do you use and engineer to check it after it's milled? I would imagine it would be oversize and strength would be based on defect numbers. I'm just about to add some exposed trusses to my build (design stage) and a friend has a swing mill to cut some iron bark. ...

No much bias there. I have found that the concreters that I have engaged to do set out of form are relatively good at what they do. I run around and check with a water level and steel tape and don't find too many issues. I think the key is to get someone to do it and get someone else to check it. Ev...

Not necessarily true with engineers and surveyors. Friend has take a volume builder to court over unsound foundation. Volume builder immediately deflected it to the engineer and put in a claim against their insurance. Watch this space.

any more updates? A family member has just started to go in the same direction against her builder.

You will find that the steel sheds are not designed to be lined on the inside. They need to be battened out for the interior lining. So you might as well construct the wall with the correct materials to begin with. Only benefit of steel is the higher ceiling that you can get as opposed to timber I t...

I thought all things trade associated were now nationally recognised. He might need to apply to get a licence in NSW. At any rate isn't it his problem to have it certified? Was it discussed before construction? Has he been paid?

get a NSW plumber to sign the paperwork is the easy solution. Probably cost you a days work for them to inspect and do it.

I too would like to know how you get costings from BIM software? How do you get the hourly rate and productiveness from it for people in the area that you live?

What is ASA? If you are referring to the Ausitralian standards, then you will be hard pressed to find any that will hand out that information. Its not really required, well wasn't when I did my course, and considering there are hundreds that are used... What are you hoping to get from an owner build...

As an owner builder I sourced my own pricing when I was deciding between bearer and joist and a slab. The pricing was based on a cleared level block ready for dusting and form. I have had a soil test done and discussion with an engineer about what was required with each design. His job is to design ...

At a rough guess from what I have been quoted: $80 a m2 for 400mm waffle pod (cheap) and 50l/m for 450mm piers. A shed slab around these parts is close to 100 m2, Looks like your quote is pretty close. Screw piers and bearers and joists work out to be 2/3 the cost, but your house will be off the gro...

If you considered alternatives to steel, you can use LVL's (use designit software). I have 3.3 cts for LVL bearers and using I joists which are spanning 4.0m (450 cts)

You need the duragal version 7 matey. You are looking at version 6. https://www.onesteelmetalcentre.com/~/media/OneSteel%20Metalcentre/Images%20-%20Products/Commercial%20Pipe/DuraGal%20Flooring%20Systems%20Brochure.pdf

check out duragal flooring system. they have a design guide or technical guide for such things. 90 x 90 x 2mm is good for 4.5m. The cheaper you want to go the more bracing you will need at that height.

make sure all the roofing is covered with some sort of barrier to prevent condensation dripping onto the cedar. Its always better to coat the side that goes towards the roofing material too. Helps prevent warping, but cedar is pretty stable.

spot on Bevan, but it will have the information that the OP was asking for in this thread.
