Amazing, so you are a top builder and structural engineer on addition to all the woodworking skills. Great video.

Exactly the way I do it, only other thing I do is take some photos of the outside walls in case there’s any existing cracks etc that the client at the end try’s to say was you!

Good one done a good few steels only difference is instead of the stud wall I'd put in a second line of props with scaffolding planks tying in the joist's .See you got your steel reinforce with a top plate . Always check your props first thing in the morning , might get about quarter turn . Lot of heavy work .👍🇮🇪🍀 Stay safe

Technical as ever and lovely neat job as usual. Like you say used to do a lot of that type of work in England. Never knew what I was doing only how to do it. Thankfully never lost one. Where I am in Oz mostly tin roofs no weight to speak of. Not many brick homes. We cut openings with minimal support and small ones with none. Tie down to stop them blowing away is more of an issue than load in most cases. Different World and like learning a new trade.

You are one fantastic builder! Thanks for the real quality info 🙏🏻

The timber frame idea is perfect..peice of mind as safety comes first with any structural load.

The beam takes the triangle of wall above the beam, plus the floor loads and transfers them down to either side. That’s why it has to be on dense concrete pads often with engineering brick “nibs” to take the weight down the walls either side. When I did mine, I put Acrow props on the inside to hold up the floor. Six more props (three inside and three outside) supported tubes cut through the wall which carried the weight of the wall. The gap was filled with mortar and natural slate as packing.

Great work again Robin. 👍🏽

Did this on the back of an old Victorian property with 500mm width rubble filled stonework. There were 2 beams at 250kg each; one on the floor and one on the top with a steel post each side. The beams were dumped half a mile away as the lorry couldn’t get down the side streets (small Victorian roads). We had to get these beams through a 2ft basement window, through a kitchen, a lounge then into position. We had 5 blokes lumping them bit by bit. If anybody’s worked on old stonework you’ll know that the rubble falls out of the middle.... interesting job. Didnt know you did this sort of work Robin. I guess when your in the trade you inevitably end up doing other work, not just your trade. Cheers mate.

Hi Robin, great video and methodology used. I had an interesting one recently which was in an old building in Sydney city and was an old wool shearing shed near the old docks. There were two timber beams that looked like they were scavenged off an old timber ship, they were massive. There was two of them bolted together. The termites had gotten into the timber and eaten the majority of the inside of the beam. I had to remove it much like you did, section by section and then new lintels and brick it up bit by bit to take the loads above. The old bricks on that building were hand made by the original convicts sent here. I say variety to your work is key so you don't stagnate, I prefer this kind of work where it is like a game of chess, careful planning and execution otherwise one wrong move and it's check mate.

Awesome video as ever RC. May I ask how is the roof of the extension supported on the existing external wall? It looks like a substantial piece of timber has been fixed/screwed to the brickwork with the new extension joists notch cut and resting on it. If so, would that leave the timbers at risk of moisture that moves through brickwork? Cheers

Thanks for sharing. I'm a structural engineer going into construction. Surprised the engineer didn't suggest a moment frame if the entire ground floor external wall is being knocked. One of the things building control moan about for the frame to resist wind loads.

Great video and information. Got my like and sub

At the start of the video you can see the end grain of the rafter up against the brick work. They have been notched to sit on the ledger. Is this personal preference over joist hangers or does it depend on what the local authority want/say?

If you can see the joists, is it essential to remove the plasterboard before putting in the acrows?

Hi. Re the steel beam, does it sit on damp proof membrane or do you use it at all re the beam.

great video. just wondering about the size of your needles. they look like 100 x 50 RHS ?

Genie lifts are okay but have there cons. There are special beam lifters about that are even better for most lifts. 👍

Hi mate, what mix do you use for the dry packing?

Very good. Can I ask a question. I have an old house the beam was out in a long time ago. But opening up some dodgy hardboard round it. I found that there is wood what might have been a lintel from the old house but just bits. Can I leave it as the house hasn’t moved or the walls on the top cracked. So it seems fine. It should I have e it take out and a pad put in. Not sure about the other side of the beam supposed as not got to that bit.

In our case the existing foundations of the dwelling where really nice and the walls where super solid, we where also leaving enough brickwork as piers to justify not needing the frame set up, this is the first for a while that we have done that did not have the goal frame set up so that was great, its really tricky because an engineer has to cover him/herself and they also have to work on assumptions etc, maybe ask the question "can you make this work with a single beam?" say hi if you see me out and about!!!

The beads should be lightly glued together. I have them in my house, and when I opened up the wall to put in a new cavity tray I found only a small proportion came out. Although I was still finding those loose ones blowing around weeks later! As you say you could use spray foam to retain them, but it effectively bridges the cavity (along the top of the foam) and could provide a route for moisture to run thru to the inside skin of the wall. Beads by comparison allow moisture to run thru the small gaps inbetween the glued interfaces.

Hi Robin, Great video. I have recently had a 2.5m steel put in place downstairs of my timber frame house. The steel was put in on a load bearing and wind ‘resisting’ (not sure if that’d the correct term!) wall. I have now noticed that upstairs - on the opposite side of the house and in other areas too, that there are 2-3mm cracks between the bottom of coving and top of plasterboard - and this spans the width of entire walls in some instances. Could this be as a result of the steel not being correctly installed, or could it also be as a result of the drilling which happened on area where the steel was installed. Basically, after the opening was created, there were bricks along the floor which needed to come out and I’m wondering if this heavy drilling might have been the cause of the cracks, or is it more likely that it’s the installation of the beam? Thanks 🙏

"Wedge and pinning" I was told a long time ago. No one knows what I am talking about nowadays. "Hope and a prayer" seems to be the order of the day when judging whether one has charged the new beam sufficiently enough with force to avoid a dreaded a second wave of forces causing more beam deflection and possible cracks to the masonry. How do you tell? Is it the sound the hammer makes when it is just right? "Overdesigning" cheap steel beams does help, but still, the crack risk must be a constant worry.
