Each truss is doubled-up glulams sandwiching 6×6 HSS connectors. Connectors are thru-bolted with 1” diameter bolts.
Bottom chords are pretty much done. They are working on the top chord, web members are tube steel, which will be welded to the gusset “knife” places.
For reference, these are premium grade doug-fir glulams (the highest visual grade), they’ll be clear finished.
