which lintels for job?

Question

I have two lintels to install.1. is in a single story pitched roof extension with a solid 9" brick wall, for 6' span French windows. Is there a 'hidden' lintel. Phoned Travis Perkins who said they have a 'T' shaped lintel. Would this do?2. is the rear 9" solid brick wall of the kitchen with bedroom above. There is already a concrete lintel allowing access to the extension mentioned above, but I want to insert a longer one to remove a 2' section of wall which still intrudes into the room.Should I go with another concrete (would be 10" wide, 9" high and 9' long!!!) or an I beam.I did phone some structural engineers and was quoted £180-350 for an inspection and calculation of the beam. One sounded quite surprised that I was calling and wondered whether I wanted to verify that a builders specs were ok.Thank you,Neil

1) 7ft T lintel is fine, off course it sits like an upside down T2) I'd personally go with the I steel, I think 2 6"x4" concretes would do italso, both these would have to sit 6" over on both sides, don't go with thebiggest size to fit the gap thats left, fit lintols or steel at same height asnow then pack gap with bricks ( or cut brick, block) and fill joint gap withslate or similar, Tel

Without seeing the job I don't think anyone would be able to say for sure what would do the job properly. It depends so much on how the existing walls are constructed and if removing any more of it would make a lintel viable for the job.

I say contract the structural engineer and take their advice on this. It's life's and loss of your property your dealing with here, and they shouldn't be taken lightly.

1)Can't see there being much weight above this (single storey is the clue).2) I agree that advice should really be taken here, but not for £200+.
