Thanks for your response. I have sent photos to you by PM. I don't know how to post photos to the forum. Re: FFL 200mm low 4Jul 18, 2017 7:27 pm John3294 Look for the three dots in the previous post Always check the FFLs before they commence site works why 1. It changes the costs of siteworks ie Cut & Fill.. if possible aim for a balance point height (optimal) 2.Incorrect levels may lead to additional engineer costs. 3.You could be in breach of planning guidelines 4. It can affect rainwater run-off and stormwater costs 5. Ideally water should run away from your footings 6., 7, 8, etc Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: FFL 200mm low 5Jul 18, 2017 8:13 pm StructuralBIMGuy @John3294 Look for the three dots in the previous post Always check the FFLs before they commence site works why 1.

If the builders had kept me informed of their schedule I would have certainly wanted to inspect the site before the slab was poured, however they didn't inform me that the construction had began until they were ready to claim the progress payment at which time the frame was virtually complete. If I had had such an opportunity I certainly would have wanted explanations why it was being set so low on the site. It wasn't something that could be easily missed, it was and is blatantly obvious something is not right. Solutions can usually be found for the technical issues, at a cost, but what are the consequences if it breaches planning guidelines? Given how much the FFL deviates from that on the plans, what are the possible ramifications of that. John Re: FFL 200mm low 6Jul 18, 2017 8:43 pm John3294 You have hit on the reason why some don't tell you when they start..they don't want anyone inspecting the work. You have to insist and even then some builders still don't tell you.They ignore Building Inspectors.. not so much structural engineers. Sorry to say the planning height guidelines are very weak to enforce after the event Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: FFL 200mm low 7Jul 18, 2017 8:55 pm John3294 Solutions can usually be found for the technical issues, at a cost, ..... A cynical person might also see that as an opportunity to make a lot extra post contract signing (see 2 above in my post) ? you will need to weigh up all the facts.
