length/width
 
I am building a new garage and have a question. I want it to be 30 by 40 and ordered 30 foot trusses. Does that mean the walls are 30 foot outside to outside/on center/or inside to inside?

That's 30 feet to the edge of your roof overhang.

You have your soffit dimensions on each side of the structure. If it's an attached garage, you may need to adjust the new soffit widths to match the soffit widths of the existing home's.
Then, you have the thickenss of your walls (2) walls. Either 2x4 or 2x6 + Interior wall finish thickness, + exterior wall material thicknesses.

All these will dictate your inside to inside measurements & your outside to outside...

The trusses are 30'. It says 24" overhang. So does that mean my walls should be 26' outside to outside?

You need to check with the truss design engineer to determine where the bottom chord is designed to rest on a supporting walll. That would determine how wide your building is. I suspect you have ordered trusses that are not wide enough for a 30 foot wide building unless they are designed for no overhang and you intend on installing them in that fashion.

other posts while I was typing answered the questions I had. Your building is designed to be 26' to the outside of the wall.

I noticed in another post you asked about how to the do the footer for this. Not to be critical, but shouldn't all of this been figured out before you started ordering materials?

Sounds like the OP needs some professional help with their project...

deere2440 03-01-2008 05:41 PM

I designed this project at menards on their computer. The design sheet says 30' wide x 40' deep x 9' high, has gable roof w/ 4/12 pitch trusses 2' o.c. On the material list it says "30' STD 4/12 60# 2' OC 2' HO common truss". My neighbor works for his fathers contractor business and am going to inquire some of his knowledge to help with my project. I just thought that I could use a site like this for more opinions. If all your gonna do is make fun of me I'll not ask for any more help.

Wooah. Chill out. No one's making fun of you.

The point is that building a garage costs a good chunk of money. Custom ordered materials, can usually not be returned. No-one here wants to see you make expensive mistakes.

I am serious, when I say that you need to have a professional (like your neighbor) look over things and help you. I think that's a great idea, and was exactly the point I was trying to make in my last post.
You need someone to help you. Even I pull in experienced friends on larger projects to get their input, their eyes, their thoughts on design, logistics, material count.

Realize that building a garage is not a DIY project, if a person has no building skills.
Even an experienced finished carpenter can lack the knowledge to properly build a large, trussed roof garage.

Be careful, plan thoroughly, get some pro input on every aspect of the project.

Check, doublecheck, and triple check your custom materials orders, and ask all your questions, before placing the orders.

Even the pros make little mistakes. I'd hate to see you make a costly BIG mistake.
Do not rely on a Big Home Improvement Store's computers to tell you everything.

No one is making fun. There are a lot of knowledgable people on this forum that can give you great advice when you need it. The last thing any one of us wants to see you do is waste time, money, or materials on something that is not done/ordered/installed properly. This is kind of a big project for a diy type forum.

I designed the building to be 30 x 40 walls with 2' overhang. That is the trusses it told me to buy. I have common carpentry skills I just havent ever built the entire project and am planning to have more knowledge when I install the trusses. They are in stock and arent special order. I told them not to deliver till I fully purchase next week. I just bought them this week because of the sale they have this week on them. I think what Im going to have to do is take a tape with me when I order the rest and measure for sue before they send them my way.

Anyway, I designed a 30x40 walls so I assume that is what they have sold me.:eek: I just was asking if that means outside to outside or on center or inside to inside. I wondered so I can get it staked out and dig the footer for concrete. If you have any good advice for me I really would appreciate it. I love doing this stuff. Last year I built a huge deck on the side of our house and installed French doors in the side of our house to walk out on it. I have helped my dad fully remodel his house and know quite a bit about running electrical and drywall, as well as framing out interior walls.

Thanks for all the advice so far.

Ok. Let's start again then. It looks like you ordered trusses with a 30' bottom chord and a 2' overhang on each side. This should allow you a 30' outside to outside width on your walls. Was the garage sold as entire package? If so, did it include an engineers certification for the roof system and a detail drawing or plans that can be used for a permit application? Also, here is a link for a publication that has everything you've ever wanted to know about trusses.

It is a kit that is gathered according to my design. I just purchased some of it this week because of a lumber sale they were having and will buy most of the rest next week. They do not provide any blueprints. All they want to do is sell me this basic how to build a garage pamplet. I was suprised because I designed my deck from them and the computer printed out a very highly detailed blueprint. I am not in the city limits and I called our courthouse and asked about a permit and they told me you only need one if im in the city limits. I dont know what an engineers certification is but havent seen one. I fully trust their trusses, many contractors including my neighbor buy a lot of materials from Menards. I plan on paying my neighbor to be present when I install them.

I will bookmark that link and check it out after I respond to all my post replies.

Thanks a lot!!

Call the county then. No way you can put up a building this size without a permit. it's in your best interest to have an inspector looking over your shoulder on something like this

deere2440 03-01-2008 07:24 PM

I'll sure check again but I have checked twice before on projects and they both times said that I'm not in the local city limits and in my township a building permit is not needed. But I want to do it legal/right so I will definetly check monday.

He probably doesn't. There are a few areas still out with very lax building requirements. However, being from from the great state of Marland, I need a permit to do just about anything on my property.
