Steve,
The sequence of bents was caused by the short bent spacing, (10-14ft centers) and the tall bent height (18ft). Bent numbers 2 and 5 where actually just prick posts in the original frame from 1888. I attached each pair of exterior prick posts with a 34ft tie beam (with two interior posts to support the tie beam), and made them into two new bents, in order to use the space above the tie beam for an upper floor system.
Bent #1 was raised (end-wall) with the gin pole on the outside of the foundation.
Bent #2 was raised and set 2 ft away from the first bent, and temperarily braced.
The gin pole was move to the other end of the building, outside of the foundation.
Bent #6 was raised (end wall)
Bent #5 was raised and also set 2 ft away from Bent #6, and temporarily braced.
The gin pole was then moved to the center of the buiding.
Bent #3 was raised and set in it's correct position.
Bent #2 was then slid horizontally into place while it was balanced vertically with ropes.
Bay #1 girts were installed.
Bay #2 girts were instaled.
Bent #4 was raised and set in it's correct position.
Bay #3 girts and door headers were installed.
Bent #5 was slid into position.
Bay #4 girts were installed.
Bay #5 girts were inatalled.
Each top-plate was made up of two joined beams, and lifted as one top-plate onto the tops of the outer posts.
The purlins and their posts/diags were assembled as two complete structures on top of the tie beams, and tilted up with the post tenons lining up with the mortises on the top side of the tie beams. An 8ft 8x8 was rachet-strapped over the splice joints to keep them rigid.
Here are some links for photos of the project, and some videos.
I hope this helps.
