New to the group. As a 15-year HVAC tech, I hope to help any and all with their HVAC woes. In the meantime, pop a cold one on me and grab a handful of pretzels... gotta question about building a deck for all you carpenters in here....
I've got a typical raised ranch with a typical 10' x 20' deck. Being an outdoorsy type, I plan to rip it down and replace it with a bigger 16' x
32'. My problem is that the damn septic tank is gonna screw up the works. I'll need to span over it. The tank is over eight feet long, which means the closest I can get two footing is about 12 feet (allowing for 18" between the footing and the tank, plus the diameter of the footing). Henceforth, my question:How beefy a girder will I need to span 12 feet whilst supporting 9.5 feet of joists? I'd like to get away with 2 - 2" x 12"s with a 1" plywood flitch plate in between. That'll give me a 4"x12" girder which will fit nicely on a 4x4 post.
Any thoughts?
