The problem is you see in the photo the short posts are on the bottom of the built stack. But, If this contractor comes on board I may see what he thinks of flying A, B & C bents and then D bent is exposed. See how long it might take to swap those posts out on D bent. If he thinks that's easily doable then I will get the TF folks to send those new posts asap. If not (I didn't mention it) and I go the short version I would hit them up for some compensation for their mistake. My "project manager" happened to be in the office of another co-worker. We thought something was obviously wrong about 15 days ago when we started spotting posts for the B bent. A phone call made it seem like they just cut those posts way longer...but they didn't.If you were closer I'd jump at the chance to recut those posts for you. Don't settle for the short posts. USe the short posts as a template, it's not that big of a job.
I've built several timber frame structures, including a 3000 square foot house. Timber framing is a hobby. I've even cut a few posts for my Amish neighbors.
