cost to build tilt slab and houses

Hi keiko,

Here's a construction cost estimate table from bmt quantity surveyors: http://www.bmtqs.com.au/construction_cost_table.htm

This will give you a guide, however, not sure about just the cost of materials with you doing the assembly work.. Hope this helps get you started…..perhaps give them a call to ascertain costs break down between tilt slab and labour. Perhaps there is a percentage guide that they use. If you find out, please post back as there may be others on this site who are interested.

I'm a structural and architectural designer, and I have a fare bit of knowledge  with tilt panels. I've designed buildings ranging from residential – townhouses/houses, commercial to industrial buildings using tilt slabs. Cost per/M² can vary depending on the thickness of the panels. I've found that using tilt slabs there is a lot more of planning involved up front (but with knowledge this is not a problem) as with all construction there are many different ways that you can approach it. If you are going to build by owner builder (for a house) I would advise to get the slabs tilted by a pro. and do the fix out to save on costs.

In residential and commercial projects, BASIX and BCA section J regulates that insulation is required. Tilt slabs save a lot of time and labor = $, if planned properly you should be able to have a house up to lock up in about 7 – 10 days (not including fix out). I'm working on a project for myself consisting of a 5 townhouse development and costings at the moment is up around the $380K mark finished and including earth works.

Tilt slabs can be cast on site for bigger panels or trucked to site for smaller panels, the biggest panel if used is 8.0m(h) x 9.0m(w) x 175mm(t), it all depends on the crane size available.

Costs (based on costs of my local tradesman)

125 thick slabs allow $120-130 per/M²
150 thick slabs allow $130-140 per/M²

Comparing brick with tilt panels.

There are 50 bricks per/M² + laying (20m² per 1000 bricks approx.) + framing if brick veneer or double if cavity brick (face brick allow 5% waste, commons allow 2.5%)

I hope this helps

Just confirming Tools & jazz77's comments – you need to be a qualified Intermediate Rigger (RI) to erect tilt slabs, and to be a qualified carpenter or builder with relevant training to join them.
