The chemical used is permethrin, it is basically a very strong fly spray. Hills Guy you do realize that timber frames come in prefab form in the same way steel does?

You can get your timber in treated pine for about 15% extra so termites aren't an issue if you don't want them to be. Both are relatively quick to install but timber is quicker. Timber is heavier to handle than steel and timber is also more difficult to straighten walls. Its much easier to make chan...

This doesn't look like the framer. The bricks work on the external corner which is the direction you should work bricks as the internal corner can use the cavity to avoid cutting bricks. This means either that length of wall hasn't been matched to brickwork or the bricks which are normally 230 have ...

You either get non treated pine or H2 treated pine, H3 is for outdoor exposed timber and H4 is below ground. There are still a lot of houses that don't elect for treated timber as they feel the physical or chemical barrier is enough. Some people choose to only have there frames treated and get the t...

Hi Peter, a timber lintel will be suitable for that application particularly because you have that post in the center and being on the gable end it wont actually be carrying roof load so it will be a smallish beam. Your drawings are good, all though your truss manufacturer may alter your web layout ...

Hi kimfyfe, its difficult to give exact sizes without knowing the full design criteria of the attic in relation to loads,spans etc. If it were to be a clear span of 3m from bearing to bearing then a 240x45 LVL would be sufficient for the joist, but I'm not recommending that without the adequate info...

Andy some manufacturers stamp there name on the ply bracing around the house so you could find them that way. I recommend asking the builder who the manufacturer is as even if you find out and call them they will probably be reluctant to give you that info without the builders permission.

A stud is not required under the truss in most circumstances, they are often required for trusses that carry loads but not a common truss such as this one. However in your case we have only one top plate which looks to be 90x45 and the stud spacings are 600mm and your supporting c/tiles. So using th...

I’m not sure why this old thread was rekindled but for anyone reading this that is a little confused. An engineer does not have to design the wall bracing, it will be designed by your wall frame manufacturer assuming your using prefab. I think there has been a bit of misconception here. Trusses are ...

Over a large volume of jobs its inconceivable to expect a stuff up never to occur, its the nature of the building industry and everyone in it knows this. Like anything when there are humans involved, human errors will occur. If everyone worked the way you describe we wouldn't be having this conversa...

Its not the pictures I'm judging you by, its your comments, if you really do work on difficult jobs then you owe the industry the courtesy of not making it sound so elementary. Nice fish BTW

The fact you think its easy makes me question the scope of your work, also the fact you believe the brick cavity can be reduced to 15mm is another reason to question your construction experience.

I think its rather naive to just say its easy, the average house slab is but complicated jobs are by no means easy. These jobs are priced accordingly of course and often commercial jobs but also some architectural plans can be enough to pull your hair out. Do you have any experience with this type o...

The builder makes the amendments.

The fact its out in two places indicates its more likely the plan than measuring the wrong side of the boxing. Once again we don't know the plan, it could be an absolute mud map we are seeing. I have seen plans where the internal dimensions don't add up to the external dimensions, which can be diffi...

Hmmm the set out was wrong by the sounds of it. They probably put the boards on the wrong side of the line. Who did the setout, Builder, grano or surveyor? One day someone with enough clout will reject a slab because it is not what was ordered. I'd be asking for a discount since they didn't do the ...

It cost just over $3,000 to add eaves to one side of our house, which is roughly 20m long - so yeah, I wouldn't be taking a front door as compensation! I think a 37m stretch would be at least $5k worth. One thing I don't understand though, if you choose to go for the eaves, how can they just put th...

This sounds about right, it sounds like you have a situation where your horizontal beam picks up trusses or rafters but then that beam lands on another beam running the opposite direction. Now that beam is picking up a point load (horizontal beam) which puts considerably more strain on the beam than...

I would say you could go up to a 2300 height assuming you have a 450 eave and about 20-22.5 degree roof which is pretty common and will leave you ample room for lintels.
