Re: F5 instead of MGP10 6Nov 01, 2021 10:15 am ![]() need to get your engineer approval or use AS1684 span tables to check. Mpg10 can substitute for f5 not other way around. Probably will be fine but should not have been done. Pretty basic issue to mess up. Hope you've enjoyed the weekend freedom after so long. Your advise meant a lot. Re: F5 instead of MGP10 7Nov 01, 2021 11:04 am Hey Annunox The certified engineering details are for MGP10 ( a higher stress grade timber) , the builder will have to go back to their engineers to recertify the engineering for F5 Their Building surveyor is talking nonsense as they aren't licenced to change the original engineering Details without resubmitting new engineering Also sounds like the builders doesn't want to pay the engineer, who knows what you'll get in the way of F5 grade, most of the timber I'm seeing are Dog house timber -> snook salmon-> john west reject (humour) .... Stand firm that's his problem Sorry for posting here, but PMs don't assist others in a similar position cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: F5 instead of MGP10 8Nov 01, 2021 2:52 pm ![]() Hey Annunox The certified engineering details are for MGP10 ( a higher stress grade timber) , the builder will have to go back to their engineers to recertify the engineering for F5 Their Building surveyor is talking nonsense as they aren't licenced to change the original engineering Details without resubmitting new engineering Also sounds like the builders doesn't want to pay the engineer, who knows what you'll get in the way of F5 grade, most of the timber I'm seeing are Dog house timber -> snook salmon-> john west reject (humour) ....

I'll insist to get the engineering updated and see how it goes. Re: F5 instead of MGP10 9Nov 01, 2021 3:25 pm As mentioned if the construction complies with as1684 then the builder can use this. The correct paperwork must be submitted, whether it be an engineers report or referral to As1684. Now what you didn't mention was were the stud centers different? or was the timber a different size. Either way evidence to show that the design complies with as1684 is what you will need.

I probably can check the timber size. Is checking the span tables something that I can do? What do you mean by referral to AS1684? Is it same as the span tables? Re: F5 instead of MGP10 11Nov 01, 2021 4:36 pm As1684 is the residential standard for framed construction. It has information about the sizes and grades of timber that can be used and in what application. Studs are the main construction of the timber in walls. They support the load from the top plate to the bottom plate. Typical materials are f7 or mgp10 90mm x 35mm in size. The 'centers' are the distance between the centers of the studs or even the pitch if that makes better sense. Re: F5 instead of MGP10 12Nov 01, 2021 4:38 pm Lots of videos on YouTube about frames. Also a series on as1684! https://youtu.be/2cszaf5IM3s Re: F5 instead of MGP10 13Nov 01, 2021 8:05 pm ![]() Lots of videos on YouTube about frames.

Will check out ![]() That's brilliant would appreciate if you have you can locate the other doc so I can use it with my discussion with the building surveyor 10 26967 |
