you're right about the bidding...fortunately for me, I am getting paid(my company) per hour per man. so the noose is done away with and it becomes way easier to focus on the complexities of this job. I am loving it because winter framing is never easy to make money....25-30% of cost goes out the window.....at -30 degrees....bone chilling expense...lol. I will keep adding to the album..in fact I plan to update the start of it.....60% of the roof is complete and there is still some huge round roofs to build front and back....front with a diameter of 18 feet and the back is close to 30 feet. The roof pitch is a 14/12 so the plumb cuts on a 12" LVL is over 18 inches. The ledger face on the flat roof is 14.25" which constitutes over 75% of the plumb cut. As long as the engineer puts his stamp on the structural drawing, the building inspectors can not over ride them. Personally, I like notching the ridge board into the plumb cuts at the bottom and letting the rafters meet at the top and then firing in spacer blocks above that for nailing the plywood at the peak. Okay so when you do your math...you determine the height of your ridge, the length of your plumb cut and set the beam ridge accordingly. This is for roofs such as a 14/12 where the plumb cuts are longer then the depth of your ridge board...it works beauts !!! Thanks for the post.....I love talking about framing !!!! I am new here but I hope to settle in soon......lots of work I would love to post...lots.....lol
