That's only 9,072 BF and that piece would be 15,963 pounds in Southern Pine. Of course, standard industry width is 10 3/4" not 11". We've made a single piece up to 45,000 pounds. Fun moving that thing around in the factory!
Yes, get in touch with several manufacturers. Contact American Istitute of Timber Construction (AITC) for a list of manufacturers in USA. I can't imagine you need just one stick like this. Is there an entire roof system?
