fellow masochists....
installing a 4.6m wide bifold to replace the original 2X openings divided by a 500mm brick pier. the steel lintle is an inverted T as spec'd by a structural engineer. this will support the internal wood frame plus the external brick veneer (ground floor of 2-story terracotta tiled roof).

the fun starts soon when lintle installation commences.
i plan to get a builder in for this task but i am keen to understand what the common practice is to support both the internal frame and the external brick veneer wall during installation.

i am assuming this will involve use of copious acro props but suspect expertise could come in handy too.

anyone out there with advice on what is a pretty critical operation. just need a few pointers to give me confidence that the builder is on track.

first guy in did not fill me with confidence (couple of props will do mate).
i dont want anyone (or my palace/wallet) hurt !
