We are planning to build With Domaine Homes in Jordan Springs, our land registers in May 2017, We have got a Tender from Domaine homes but it looks in absence of contour /geotech report or soil test, they are provisioning for additional costs cost as listed below:
1. Salinity affected environment - $3000
2. H1 class slab- $2000
3. PA - provisional allowance, dropped edge beam,piering,rock excavation etc- $10,000
4. PA- for Bush fire attack level (BAL)-12.5 $8,500
Now, I understand that as there is no access to land so, these cost is budgetary only, the land seems to be fairly levelled as per standard site cost guidelines . My question is, has anyone has got soil test report come positive for Salinity? I understand that most builders would do H1 slab in newer estates, I am trying to understand how much of those are actually required.
Can people building in jordan spring east comment on salinity
Thanks in advance
