I have just been informed by the structural engineer that the builders have not followed specification for goal post steels. I have been quoted £600 for the welding to be done to have it corrected. Also, the plate is upside down. The RSJ is to one side not middle and plate is extended which is underneath outer skin wall. Engineer said plate should be on top not bottom. 1 post in tied into my exterior wall and the other post is bolted to party wall. The RSJ's are like old rust buckets with no coating too. Should the plate be at the top ? If so I am going to find a competent builder to remove steels (except one knitted in wall) so that specification can be completed.
Are you a tradesperson and able to answer this question?
The structural engineer's drawings will have to read correctly and any installation will need to be carried out to all specifications. This is key to ensure that the build can be signed off and meaning that you can continue to mortgage your property and sell on correctly. The building inspector will require to see the designs and ensure that correct insulation has been carried out.
If the structural engineer drawings show the plate being on top. The plate must go on top. Another option would be to get the structural calculations reviewed to take into account the current builders mistake.

Bearing weight plates should be under the beam, sitting on the wall... bearing weight its at the bottom.... top should be flush with wall/joists..... not sure but the sound of it its confusing... i would need to see pics or plan... its not clear other than that plates are at the wrong side if they are up and nothing its between bricks and rsj
Then yes it must be coated... rust prevetion its very important to
Wish you the best of luck and my best advise its to find few more people willing to have a look at it... best bet... find an ongoing extension that looks properly done... best way to recognise that its a clean and organised site.... find the supervisor or manager and have a chat. Am sure you will find what you looking for... take few pics and any plan you have with you. Am sure you will be sorted

Bearing plate or pad stone sits under the steel beam. The plate which is to carry the external brickwork should be welded to the top of the beam and generally set back 10/15mm from the outer face of brickwork. The best option is for these beams to be galvanised (expensive added cost) but depending on your geographic area and size of steel, you may be able to use bitumen 2 coats. The use of a cavity tray is advisable as well.
