Around a shower the studs should actually be at 300 centers and if all walls are tiled then 450mm centers should be the maximum spacing allowed allthough I would still go with 300mm centers. There is more to it than just what the maximum studs can be centered at because the roof load and top plate size must also be considered. Internal non load bearing walls can be a maximum of 600mm centers and a 90x35mm top plate would be sufficient. External walls can be a maximum of 600mm centers as well as having a single 90x35 top plate as long as all trusses are sitting directly on top of the stud. Alternatively when using a double top plate then 450mm centers are mainly used because then the trusses wont need to sit directly on a stud except for all girder trusses which will still require double studs to be directly underneath them.

Hope you dont mind if I can ask you a few questions as you seem to know whats what. Im about to choose a volume builder, some say they use 450 centres some 600. Ive been told some can go out to 900 Im not sure about this, is this the walls or the roof truss spacing. ( Im not a builder) Im concerned as to the quality v. price that some volume builders use in the house fraim. I hope you can share your valuable knowledge in relation to the follow: What differance in the roof fraim for colorbond & concrete tiles? 90 x 45 timber as oposed to 90 x 35 which is most commonly used? MP10 (I think) grade timber what other grades are there? Hard wood as oposed to pine, whats the diffrence? Battens on the roof, wood or Zink Whats that all about. How will I know what timber the builder is really using on my house? Hope you can help. It would be much appreciated.

Re: Frame standards? 8Nov 02, 2008 3:33 pm What difference in the roof frame for colorbond & concrete tiles? Colorbond roof framing only requires trusses to be spaced at 900mm centers so there are less trusses needed overall. A tiled roof needs the trusses spaced at 600mm centres which means more trusses are needed.
90 x 45 timber as opposed to 90 x 35 which is most commonly used? Most volume builders would use 90x35 as that is cheaper but some will double up the top plate so its then 70mm thick. Most studs are commonly 90x35 but things like window studs are 90x45. Not many volume builders use much 90x45 for example Henley don't have one piece of 45mm timber in the whole frame, the use all 35mm. Few companies such as Colex Homes use all 45mm top and bottom plates as well as all window studs and internal and external doors. MP10 (I think) grade timber what other grades are there? Again most volume builders will use F5 studs and a maximum of MGP10 but some will use MGP12 which is better and more expensive. Its basically a better quality pine that is straight and less prone to twist. Hard wood as opposed to pine, whats the difference? It is very rare to have houses built in hardwood these days except for the hardwood lintels Battens on the roof, wood or Zinc Whats that all about. Its either timber battens which can be either hardwood (better for colorbond) or 35x35 pine (for tiles). Zinc is basically a metal type of batten but I haven't used them before so I don't know much about them. How will I know what timber the builder is really using on my house? All timber is stamped with its rating so you can see it. Hope that helps you but if you have any other queries don't hesitate to ask. Just out of curiosity who have you decided to build with? Re: Frame standards? 9Nov 02, 2008 6:07 pm PD Prestige use 90 x 45 ...or at least they did on my house! But the tradies def said the same thing (among other things) about one that you mentioned. I really would have no clue, but DH checked out ALL of that stuff , rating, etc, as it was done....luckily, he DOES have a clue !!!

Thanks kindly for your info. Yes it has helped. Im thinking of NBG can you give me some info on what they are doing re. centres, timber etc. A & L window what do you think. I used to buy a bit of timber and I know you get what you pay for. I used to buy merch & standards for picture fraims. The more knots it had the cheaper it was. If you left it to long it would bend like a banana. Are knots in a fraim a big deal. Also I know you cant see it after, but I see when sometimes a builder cuts a bit short they pack it with MDF. I see it a bit with noggins. Is this normal or just being a bit rough. Also split and chipped timber at joins, Nails fired at an angle and they split or miss the timber. Is this sub standard or par for the course. I suspect its time, money v. quality. Whats you over all opinion of NBG. Have worked on a few sites myself Im concered I may be a bit picky with my builder as i will be checking the place out stage by stage, but dont want to be a pain in the ***. Also on the plan, working drawing it should tell me centre spacings and timber thickness around windows, right. Thanks for your kind help.

Re: Frame standards? 11Nov 04, 2008 2:40 pm I don't know anything about NBG except there prices are quite cheap. The plans will tell you about timber sizes and stud spacing etc. A&L Windows are good quality so don't worry about that. Knots in pine is common but MGP10 or 12 is a lot better than the standard F5. I wouldn't be too concerned about some short noggins that have been packed as this would usually be at a corner to make the external corner straight.

Re: Frame standards? 13Apr 18, 2010 9:09 am I needed a copy of the structural engineering for the frame and bracing so Alex the building surveyor can do his inspection. I was told by Carlisle unless its a double storey engineers no longer do a structural report or plan for frames. Instead all frames for single storey are built according to section 16 84 of the building code Does anyone know anything about this ? or have a copy of the section 1684 re frame & standards. Subsequently I found out the Truss and frame manufacturer is the source that can provide me with this info. If I dont get this info prior to the inspection ,Iam wondering if its a worthwhile getting one because how will he know where the bracing is supposed to go etc? each house is different. Re: Frame standards? 14Apr 18, 2010 9:33 am Hi andy, if your in SA I can help you out. If not you can buy a copy through "SAI GLOBAL" http://infostore.saiglobal.com/store This is 100% true.
