The outfit I've asked for a quote said $600 ex GST. Is this a reasonable price ?? Chris Chris, which engineer designed your slab? They should be the ones inspecting it to ensure it is as they designed. They would normally charge a site visit rate of around $150 per hour (travel and site time). JB Re: Engineer's inspection costs ?? 4Feb 20, 2009 12:36 pm Quote: what does the 600 include. Are they going to xray it are just visual inspection??? Good question! I 've no idea!! Shows how little I know about it. I'll have to call them and check. Would you guys fill me on what's such an inspection like and what're they using ? Quote: $150 per hour I wish! The best quote so far, from another outfit (not the one asking for 600), was for $200 to come out and $200/hr.

It should be part of the certification process if you are building... And as such included in the certification costs... Electrical Engineer... Don't hold that against me... And keen owner builder... Mainly the building part!! Re: Engineer's inspection costs ?? 6Feb 20, 2009 12:57 pm chuth77 What do you need it inspected for? It should be part of the certification process if you are building...

Re: Engineer's inspection costs ?? 7Feb 20, 2009 1:01 pm I need an inspection, 'cause I'm not happy with my slab - there're too many cracks, the concrete seems too thin under the wet areas, so I'd like it to be checked by someone qualified and I need some advice about repairs.

How can you tell how "thin" the slab is in the wet areas? Again there are Australian Standards on the required thickness. If it's not to spec, simply ask the builder to show how it conforms to the standards and Building Code... If we can help, let's know the above details... It may save you outlaying for an engineer....

Quote: How can you tell how "thin" the slab is in the wet areas? I've decided to have an engineer out, so I can fix all slab problems and finally move forward. All these problems're delaying framing and what follows, by more than 2 wks now!

we are building a house in melbourne at the moment, and we have a very large number of hairline crack in our slab also. I noticed a few cracks a month or so after the pour but nothing too serious. However things really got bad was when we had a 47DegC day a few weeks back. We had cracks running left, right and centre. Some running continous from one side of the house to the other. Anyhow, I called the builder to have it inspected but I was worried that the their opinion would be biased so I found myself an independant building inspector to check things out. They told me that if they looked at the slab and had any reason to suspect it was more serious they could order an engineers inspection ( possibly more expensive) to check it over more thouroughly. As it turned out, it was only shrinkage cracks which are not good, but don't cause any real structural concerns. The inspection cost us $560 inc GST, but I still feel it was worth the money just for peace of mind. I would say if you can get an engineers inspection for $660 to save yourself a lifetime of worry then it is money well spent. Even if the report shows there's nothing wrong, at least you wont be forever wondering. Jamie. Re: Engineer's inspection costs ?? 11Feb 20, 2009 8:35 pm There is a monitoring period of 12 months for hairline cracks... Believe it or not, the slab is only deemed defective if the cracks are larger than 2mm after this period... Electrical Engineer... Don't hold that against me... And keen owner builder... Mainly the building part!! Re: Engineer's inspection costs ?? 12Feb 24, 2009 3:33 pm $600 may be reasonable as you are after a report on the slab rather than an inspection. 80mm is too thin. In stepdown areas the slab should still be 100mm (if thats what the plans say) and have the level of the sand adjusted to suit.
Regards Paul Re: Engineer's inspection costs ?? 13Feb 24, 2009 7:02 pm 85mm is possible if it's a waffle pod... Otherwise slab on ground should be 100mm unless detailed by the Engineer design...
