thanks Bertie Will have a new builder bond on structural ply to either side of the webs to bearing end. The engineer said strike a 45 degree angle from the corner of the notch to the upper flange and add 100mm which will govern how long the ply needs to be.

thanks for the detailed response. The engineer specified ply bonded to the web up to the bearing. The manufacturer sent me the data on the i joists so I have sent the that to the engineer to see if it changes his solution. I was advised by a specialist company that at the bearing the only...

thanks Tony. At least I know I have options. I did think about the timber across the back with joist hangers but the engineer wasn’t convinced. That would make the most sense to me as we can then just cut the i beams back to their normal shape and essentially shorten them then hang them. The...

thanks Jed I thought cutting into an ibeam is a no no . Would these remedies apply to the way he has cut out beams ? He’s essentially cut the bottom corner off the beams with the bottom flange overhanging the steel beam by about an in and half. How could I tie that into the steel now ? Would...

the calcs that were done was for a lintel not as high but due to lack of stock they had to call the engineer who had a look through their product list and picked a different height steel. So that’s why the steel has ended up higher than the ibeams. I didn’t think an engineer would make a mistake...

Thanks for the reply. 1 the beam is large. I don’t know the exact section size. I have attached a picture of it. The steel is 30cm wide by 3300 long. 2. Yes there is a plate to support the outer leaf. 3. He has just gave an opinion so far a deeper investigation will be needed if I can’t find...

Hi all So I’m having 3 meter bifold doors installed in my new build. The whole needed widening from 2 meters to 3. I had the engineer do calculations and we had the steel fabricated. Because of a stock issue the steel had to be made slightly higher than it was originally because we had a...
