Roof Deck and Knife Plates

Well I figured since I'm getting ready to go down for the next site visit I ought to give an update of the previous visit.

J&D had started a variety of details for my review.  The most critical perhaps is the integral box gutter that we have designed to drain the roof deck portion.  Because we didn't want any scuppers or exposed downspouts we went with the integral gutter with the downspout concealed in the lower wall construction.  This had a variety of potential hang-ups but it all came together and performed well in the first downpour.

Box gutter through notched beams
Downspout concealed in soffit/wall

The other detail that I have been really excited about is the knife plates to join the cedar beams to the steel w shapes.  Here's what we designed and it turned out great.  These will all be left exposed
