I'm supposed to do the stormwater after handover but I'm puzzled by the proposed stormwater pipe going under the garage slab, I won't be able to do that after handover obviously so I think I will have to change the stormwater design when I get plumber to do it. I am after some comments on the overall slab levels and also the drainage system for the site. I'm worried that the neighbor levels are higher and that water might drain towards my slab. My garage is going to be on the boundary and builder is engineering that but I'm wondering if I need to do any additional drainage along the fence to prevent any water going under the perimeter path and the slab. Cheers, Re: Engineer report stormwater 2Nov 04, 2019 7:58 am If your civil drawings were done correctly you would not be asking any questions now. Isn't engineering of the drainage to account for the site levels? Also there should have been a note to say that your builder to provide under garage drainage for a future stormwater system. Why isn't your builder doing the stormwater system upfront?" A lot of damage can be done to the foundation of the home during construction if there is poor drainage, you will get blamed.

Here's a typical scenario 1. Stormwater Typical (Planning stage) PS 10K or left TBA at Planning/tender stage 2. At Building approval Stage client gets $sticker $hock and told Pay up or DIY 3.In the old days the Council Building department would then reassess the application and point out issues to the Builder if the clients DIYs 4.Now that the Building certification is done independently by the builders Building Surveyor It is often ignored and the client is left in a worse position than when they started ..no fault of their own 5. A case of poor/lack of regulation/duty of care and possibly a class action against the council? Record Class Actions Drives up Costs 6. I would be lodging a compliant about the Builders Building Surveyor and the council failed to follow up on the changes to the site plan Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Engineer report stormwater 4Nov 04, 2019 10:12 am In Victoria it has nothing to do with the council, it is the relevant building surveyor that interprets and administers building act and regulations for compliance. Building surveyor will not know if any changes are required to approved plans after approval. It is builder's duty to construct in accordance with approved building permit drawings or seek a variation under the contract, specifying why it is required. The proper procedure is to raise building variation, get owner's consent, seek design review, submit revised drawings to the bs for approval and amendment of the building permit drawings then implement the variation.

It is the relevant building surveyor that will assess the adequacy of documentation for the building permit. In structural matters it is usual that the engineering design is supported by (peer review) certification form a second independent engineer form 14 RBS will then rely on the two engineering certificates as proof of adequacy and will issue the permit. In simple matters second certification may not be required and in the cases of home extensions no engineering altogether may be required for footings or slabs where there is in service proof of adequacy of the existing structure. NCC allows for that.

Let me tell you where it's heading, soon you'll need Engineering Certifications for a new Brick fence footings " That's the hard line now being adopted, having submitted 2 to council this week where Battlers and punters are told no engineering no building permit by Council Surveyors OT, I now advise front loading ( and checking) of engineering into your designs for builds here's why 1.Best to know the worse case scenarios upfront 2.Engineers are trusted by society with data and proofs 3.If mistakes are picked up early they can be fixed on site then and there by an engineer 4.Structural Non compliance can only be dealt with by engineers 5.Battlers and Punters are tired of being whacked by excessive engineering upgrade costs after signing initial agreements with builders 6.7 Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs 3 6316 The engineering is the engineering. It's irrelevant how much material you have. Unless it fits the requirements of your design the engineer can't "make"it work.
