Site set out on home extension-Melbourne

Hi everyone
We are going to build an extension (about 190 sqm includes 3 bedrooms and 2 toilets and living room and kitchen).
My husband is going to be the owner builder.

My question is do we need to hire someone to do the site set out for it? Or it is concreter’s job to do it?
If we do need someone, does any one know how much the cost will be approximately?

*we have very limited budget so we have to be very careful on we gonna spent.

Thanks in advance.

Hi karen5784
The concrete contractor will set out the site and you will need to check it
I recommend you Have
1. Full set of plans , Engineering Details, Specifications,
3D BIM (Building Information Model), Data and Costs
2. Use the BIM model to order materials, sequence (project manage tasks on site), coordinate the work/trades, do inspections, check engineering, etc,etc
3. Access Expert Trusted advice (Design, Engineering,Construction, Your Own Virtual Reality Project BIM Model) over the internet
If you are looking for that type of assistance then please leave a private message
Glad To Help
Chris

Thanks Chris! Funny that my designer say he will ask his builder friend to do the site set out for me cost about $500 but I doubted it should be the concreter’s job which we have paid already.
I don’t want to pay double for the same service.

I don't see why you have to pay the designers mate $500 to put a few pegs into the ground?
As I said the concreter generally does that unless it's a boundary wall, in which case you will need a licensed surveyor $500
But I still recommend you run tape measure along their string line.. check it yourself.
The designer should have given you a set out Dimension Plan?
Also why have you paid for the concreting before it's done ...just curious

A big thank you Chis. That’s what i thoughts too. Cheers

carpenter is the person for that job , as a carpenter i can say i would never let a concreter set out or build formwork , they have their laser level set to 5mm tolerance and they move the stick til it makes the right beep.

as for the cost its usually around the same as a piece of string

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. Everybody loves to find fault in other people's work.
