Without knowing any better, the builder and architect could be correct in this instance, technically speaking Hi Boris, I’m not sure if you are right about cdc approval doesn’t have engineering details in it. That’s something I need to find out, but I’d assume it does as the architect has been waiting for structural plan and stormwater plan to finish, then told me that we are ready to submit. I will find out.

Re: Screw piling chosen without the geotech report 15Oct 19, 2021 4:43 am Ashington Homes Savagepuppy Hi guys, Just got the structural plan from my architect. Before the plan started I asked the architect if a site visit by the structural engineer was necessary and he said no. Turned out the structural engineer did the plan without a geotech report, and his reason was he did a few jobs in the area, most likely it is sandy soil. So screw piling is the only way. Now my architect is saying I should get a geotech report, which I’m arranging now. And he can either get the current engineer to update the plan once receiving the geotech report, or get a new engineer. As I’m going through CDC, my builder is saying I should go ahead with the plan for CDC approval, and we can always amend the structural plan without any problems even after cdc approval, which seems to be a common practice. Any comments/suggestions? Judy Hi Judy Is your issue that you would prefer concrete piers over screw piles or are you trying to save money by having neither? Just trying to understand what outcome you are hoping for. Cheers Simeon Hi Simeon, Thanks for your response, too. I managed to have a chat with the geotech engineer today, and he said that he would recommend raft slab or screw piles for the area. Is raft slab different from concrete pier again? The geotec engineer believes that the builders prefer concrete pier because they can do it themselves, but they most likely need to subcontract screw piling company to do screw piling, so they won’t make money themselves from the footing. My architect now seems to think it’s necessary to get the geotech report done so that there is no variation on the footing when it comes to signing the contract with the builder. Where are you building at? It’s good that you know what you are doing. I don’t have it all under control, in fact , I don’t know much about construction. And because of my current structural problem, it’s important for me to get the new foundation right. Good luck with your new build.
