Hi Ken;
...
This post/plate/tie intersection in this framing is a rare example of reverse assembly where the plate is on top of the tie beams rather than normal assembly where the tie beams are on top of the plate. It looks like the assembly requires the bents tipped up with the ties in place but then the ties would need to be elevated so the plate would slip onto the tie beam tenon. In the U.S. we also have what was dubbed the triple bypass joint where the assembly sequence also requires lowering assembled tie/plate connection down onto a flared post as seen here:

Jim, had the pleasure of working on similar joinery on a barn in Ohio in 2000 or so. Monster oak tie beams, 12x18 posts or so, gunstocked in the direction of the plate.
Raised bents, then blocked up the tie beams. Plates slid onto tenons, then the entire assembly was to be dropped down (2", more? can't remember the details) or so. We burned alot of crane time setting the plates, and in the end, cut off several of the tenons as things just would not go...
Can't find anymore images. Pretty sure I have a stash of slides of all parts of this thing somewhere...
