Shawn – I can appreciate budgetary concerns, but there is much there, and it is probably an easier chore to bring it back to its intended working configuration than you might imagine. I also have met Tom, he and his partner were guest speakers at the PDW a few summers back. While I'm sure they could be of great help, it may be less expensive and answer more questions if you brought in a timber restoration specialist, as they might provide more insight as to rigging scenarios, they may also have a better eye or methods for finding signs of rot ( a timber that has been wet over a sustained period, will often look relatively sound on its exterior but be compost inside – look for water stains, mold and listen for hollow thuds – And that resistance drill was not a stretch, perhaps IML can point you towards someone in the area that has one ) in the rest of that Tie or adjacent members,.

Running calcs on that tension scarf will be in order, the dueling struts will see be having it doing its duty.
Speaking of the struts, they usually fall over braces, I can't tell for certain from the photos, but have some of the Tie to post braces been removed ?
You should expect to pay their going day rate plus mileage, plus a fee to prepare a report if one is desired.
Best with it -
