I was in your same situation earlier in my career, in a large Australian consulting firm. We had compulsory 9pm finish on Thursdays on top of all the other overtime. I can give the following observations: - Unpaid overtime is 100% profit for the company. It is a culture in the large firms to...

Thanks for all the help everyone. I will take this all into consideration and tell the client what I think. Also, rust is definitely something that needs to be considered as XR250 points out.

Thanks all. Just to clarify as I was unclear in my post; the purlins, diagonal bracing and roof frame will remain and only the roof sheeting will be removed. It will not be replaced with a skylight or anything similar to resist wind pressure or seal the building. I will be checking the purlin...

Hi All, One of our clients has a restaurant, about 15m x 30m with a 5 degree roof pitch, which is currently fully enclosed. Our client wants to remove about 20 square metres of roof sheeting to allow part of the restaurant roof to become open. I'm wondering if anyone knows how this will affect...

I'm not an expert in material/prototype testing, but I have worked on a few projects where prototypes were tested and the capacity factor determined. In these calculations there is a minimum reliability index that needs to be achieved and in doing so both the material capacity factor and load...

I would email the engineers and ask them if they actually sealed/approved it. I like it when someone contacts me asking if I actually did a project or if someone just copied my details.

The limits are whatever the judge decides on the day [afro2]

Thanks all. I was after peoples personal experience and these are all valuable perspectives that I will internalise. My original intention was not necessarily to get into a debate. As you say, in terms of professional engineering this is a contractual / client communication issue. I'm wondering...

Yes, this was my experience also until the last year. In the past, all we would do is write a single page letter explaining that the design was a performance solution and that it met the performance requirements with some brief rationale; and I have also seen this a lot from other engineers...

Thanks CVDP75, this is useful information. We provide engineering services in every state (since many of our clients have outposts Australia wide and need their pre-fabricated buildings certified for each state). However, at the moment the state in which we have the most difficulty is Victoria...

Thanks all. As far as I can tell, this will soon influence most structural engineers, whether you've already encountered it or not. The reality is that most engineering designs can be interpreted as performance solutions by someone and the onus will be on the engineer to prove that the design...

Thanks for the feedback Retrograde & human909. It seems that this is the case. I've watched presentations by the ABCB and even they recommend hiring a BCA consultant in order to guide you through the process. My clients have asked for quotes from BCA consultants and the price starts at around...

Hi all, I'm just wondering what people’s experience is with the new NCC 2022 Performance Solution Process? It seems to be having a big affect on my projects personally. I’ve listed a few points below but I’m also wondering what the general experience has been from other people's perspective. 1...

I think this is a good point. If the beam did fail, for reasons not to do with the engineering (for example builder's negligence), then having FAIL written on the report would not do you any good in a court of law where the outcome of the case is decided by the emotions of a single individual on...

Thanks guys, I'll go with that.

Hi IDS, thanks for the help. It is technically a dome but with a large cut-out at the front and smaller cut-outs between. I thought to look into arch action for the front section as a verification, and use a full model of a dome (with cut-outs) for the rest. It is essentially the same as a...

Hi all, Firstly, thanks for any help on this. Please see the image below. I'm just wondering if anyone has any ideas on loading an arch or dome which is being covered in sand? I was thinking of just super imposing the vertical and horizontal load. The vertical load would be a simplified...

I've probably done 50 of these, and the company I used to work for would have done at least a thousand. The rule of thumb there was to extend the suspended slab longitudinal top steel into the ground slab and lap over the ground slab mesh. The distance of the extension would min of 1.5m, or...

1.02 is 3 significant figures. Is every single value you're using in your calculation 3 significant figures? If only one value is 2 significant figures then your answer is rounded to 1.0. This is one of my pet peeves when it comes to engineering calculations. I see calcs where, for example, the...

Hi All, Please refer to pages 565 onwards from the NCC 2022 housing provisions (https://ncc.abcb.gov.au/system/files/ncc/abcb-housing-provisions-2022-20230501b.pdf). This is the WA state variation in the ABCB Housing Provisions, but a similar variation is in the NCC Volume 1. The variation...
