Have been a long time reader - first time posting. Sincerely hoping someone can help my hubby and I.
A little background - we are building with Carlisle homes VIC, our site is a knock down rebuild, demolition has been done a couple of months ago and have been awaiting the hydraulic report. Site is a P class and classified as in floodzone according to Dandenong council. Slab is a Waggle raft slab with screw piles. Have received notification today that there is a 200mm difference between our first survey report pre demolition and second survey post demolition. They have stated that we need to import 150mm of fill to site over entire building platform in order to meet Melbourne water flood level requirements to have the building permit issued at a cost of $11,500. Additional site costs prior to this total approximately $60k on a level block (850sq). The site costs are to the point ($70k+) where we are seriously considering pulling out of the contract. Can anyone suggest how I can challenge this additional cost? To my limited understanding the floor height has to be higher (300mm) above the flood level height. I have asked Carlisle to supply me with the council report stating the flood level and break down of the stated cost for the infill. All I have been supplied are the surveying report and stated costs. Can anyone please guide or assist me regarding the steps I should take, it would be greatly appreciated.
