Building to code?
 
Hi Their,
I'am building a 24'x40' Car Port and I'm using 6"x6" Treated Posts (6x6x16) sunk in the ground 3' with a footer at the bottom and rest with concrete to a foot above the ground and tapered around the pole to shed any water. Beams are going to be spaced apart every 10' and bolted to the 6x6 posts (I will cut out an 'L' slot on top of the posts) with (2)2x12x10' glued and nailed together. Using 10' sections to make it easier to work with just 2 people. So their will be (4) 10' sections of (2) 2x12x10' beams bolted (2-bolts per end) to each posts on each side. Now the roof will be constructed with (21) Standard 24' Trusses with a 4 in 12 pitch, spaced 2' on center with a 2' foot over hang, 1/2" OSB, 30lb felt,3 tab shingles will complete the roof. Ok, so I went to local lumber yard with my plans in hand, talk to engineer at the truss plant and he said that (2)2x12x10' will be ok for the roof system I'm going to use. But when I went to get the Building Permit the inspector who will be inspecting my Car Port said that I needed (4)2x12x10' beams!!!. Who's right...an engineer or a person(non-engineer) who just reads the code book...and is going to either pass or fail ur project!!!. BTW I'm just a home owner wanting to do the right thing by getting the Permit.

Rule #1 - the inspector is always right
Rule #2 - if someone tells you different, see rule #1

the engineer might be correct in saying that 2 is all you need for it to support the load, but if your local building code requires 4, than you better just whip out the check book and order 4. you won't win this battle so don't risk getting on his bad side, it will end up costing you a lot more than a couple extra trusses

Funny u should say that!!!...same thing my wife said!!!. But, really now isn't (4) 2x12's a little overkill?. Three(3) maybe....but (4) 2x12's!!!. Give me a break.
