Just before the contract our builder has advised us that Screw Piles would be needed for our house as there is a sewer pipe on the easement in front of our block of land. The sewer pipe details are: Size - 675mm, Depth - 8.32 m and offset - 1.23 m.
Screw Piles will cost 10k and this will raise the site costs of our house to 25k as it already has a H class slab.
Could anyone please help us to understand why screw piles would be needed.
Would it be ok to build a house in this situation with the gutter and the screw piles. Can there be more site costs that can come up during the construction.
Our builder "H" had not advised us of these screw piles during the initial tender after the soil tests.
We are even thinking of selling back the land to the estate developer but that would mean we'll lose stamp duty and the estate owner will buy the land at price determined by him.
