How much for a house foundation concrete slab?

lorrainey100 · Oct 19, 2018 4:28 pm

Just wondering if anyone can help me? I am building in a rural area in East Gippsland Victoria about 100 km from the nearest large town and I was asking around for quotes for a foundation concrete slab. The specs are:

- 32 MPA for semi-polished concrete floors
- house foundation is a large rectangle 18m x 7.2m = 129.6 square meters
- raft slab
- soil classification is M
- fairly flat block 1 acre, I've talked to some excavators in the area who have excavated a house across the road and they said it was a low problem site
- easy access to site from the road

I have been receiving quotes between $30,000 to $38,000 including GST which includes site preparation and excavation, formwork, digging edge beams, pouring concrete and finish and a concrete pump.

The cost seems to be between $240/m2 to $292/m2. Does anyone know if these costs are reasonable or excessive?

Lorrainey100 welcome to the forum
That is a great request for Information (RFI) The only thing missing is a site photo and Floorplan?

OT Some trades often take advantage of owner builders, here's what to do
1. Detail, Plan and Cost whats involved
2.Have proper Engineering/Construction Drawings, Specifications, etc
3. Compare & evaluate at least 3 written quotes
4. Break down the project , explain Data Visually and hope to negotiate-> aim for a fair price with the preferred subcontractor.
5.Take control of your project
More info required
Cheers

Thanks for replying

1. Detail, Plan and Cost whats involved - I provided them with an architectural plan and drawing

2.Have proper Engineering/Construction Drawings, Specifications, etc - I provided them with a structural engineer drawing

3. Compare & evaluate at least 3 written quotes - I've requested at least 5 quotes

4. Break down the project , explain Data Visually and hope to negotiate-> aim for a fair price with the preferred subcontractor. - I think this is my next step - I will be breaking it all down and getting contractors to cost individually.

5.Take control of your project

Maybe get a cost breakdown splitting the foundation cost and the finishing of the concrete as in cut, polish and coat.
