Re: Slab for garage - is engineer over engineering it? 19Jun 09, 2018 10:00 am alexp79 They are putting their business reputation, legal and financial responsibilities at stake here, hence, under engineering is highly unlikely. It is still much more highly likely that engineers will over-engineer then under-engineer those days. Also, I am building with Nexcem/Durisol ICF and this particular engineer has a lot of experience with this type of technology and have designed few dozen houses already, so I have more grounds to trust him rather than the previous one, who most probably designed footings to full masonry standards. The new Engineers act will also protect Punters from New technologies and internet marketing Spin. If anyone wants a list of failed technologies with data and proofs from an Engineer that specialises in Structural Repairs please leave a PM.. (Forewarned is forearmed) OT Engineers are generally conservative that is why society TRUSTS them Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Slab for garage - is engineer over engineering it? 20Jun 10, 2018 1:50 am StructuralBIMGuy alexp79 They are putting their business reputation, legal and financial responsibilities at stake here, hence, under engineering is highly unlikely.

(Forewarned is forearmed) OT Engineers are generally conservative that is why society TRUSTS them On the other side, engineering is not a rocket science after all, pretty much everything can be modelled and calculated, the physics and formulas around modern structural engineering is well known for ages. Engineers in other countries design and help to build modern houses on 70 degree slopes without too much worries and use some of the "modern" technologies for centures (e.g. in my case, there is nothing new in woodcrete or arbolite on its own and even less new when using it as a formwork for reinforced concrete (in ICF style)). I have seen couple of companies who even 3D print houses with some special reinforced plastic. I am not really sure if "protecting from new technologies" is something Australia really needs. E.g. in the US recently a couple of building "startups" have disrupted the whole industry, I can see it easily happening in Australia too - there are already brick laying robots which can lay bricks faster and better (Australian start up by the way), rendering machines which can render 1000 sq m a day and with a better quality. I really can't see any single reason why robots won't be able to replace 80-90% of the remaining tradies as well as building material production jobs in 3-5 years. But yes, there and always will be cowboys in any industry and there will be always failing technologies. We should be doing our best to learn from the past experiences, but simply rejecting anything new and innovative and claiming it an "internet marketing spin" is never an option. Only engineers which were able to think out of the box and move forward with innovations are responsible for the progress of the humanity, after all. PS. And yes, on the below photo, a post mortem of Katrina hurricane, this is the house engineered and built with "new technologies" in mind, while the houses around it were designed and built by "conservative" guys. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Just my 2 cents, please do not take anything personally. Assuming you've modelled the TB8, TB10, TB12, TB2 & J1 joists/LVLs there, it appears as per drawing to me. There maybe should be an additional J1 between TB10 and T12 if… 3 27685 Thanks for all replies. I just noticed now the pictures I added to post right on top of page were wrong.
