Above 1200 Sq/FT FINALLY approved

[supratreo]

So after over 9 months of going back and fourth with the city, our shop plans are approved. Cant wait to get started but unfortunately the weather here right now *****. I'll get with my concrete guy and see when he wants to start and go from there.
I'm also really considering doing the framing myself. I'm no framer but i can def swing a hammer (or nail gun). the 10x12 shed but next to the shop was built entirely from the ground up (minus concrete) by my father and I. only thing new to me is building a 12' frame on a 2' stem wall. trusses will be prebuilt.
i know there a ton of variables but what are your opinions? I did ask around for quotes and so far I've only received 1 for $26k labor only for framing and truss install (no sheathing). i don't mind spending the money if that's what it comes to but it would be nice to build the shop I've always wanted and have another project for my father and i and a couple close cousins.
also, for anyone wondering, we're building off the existing shed so that we can call it an addition to that structure. otherwise we'd have to leave 5-7' and that would just be a waste of space. On the plus side, i can keep my compressor in the shed for safety and noise.
below is what it will look like.
like always, any input is greatly appreciated and thank you to everyone here that posts ideas, very helpful for someone like me who's going through this process.

That’s a WAAAY bigger project than a 10x12 shed. That said, do it. If you have the tools/equipment and knowledge - why not?

 

[supratreo]

tools and equipment yes, knowledge, kinda. i'm still taking in as much knowledge as i possibly can on framing so i know full well what i'm getting into.
your def right that this is a WAAAY bigger project lol.

What's the purpose of the building? Your plans state no vehicle parking I'm guessing that's because the slab has insufficient strength. Seems a bit odd for a garage/workshop!

 

[DeeDubz]

26k just to install... thats wayyyyy too high. Im just a little north of you. Im sure there are better deals out there. If your doing stick its going to cost more money. Metal is a lot less expensive, in my opinion way easier to build.

 

[supratreo]

the building will be for a home shop. 1 lift (i will be doing 6" concrete for this area). its being built as a "barn" so i believe thats why it states that, its not being built as a "garage". i'll have to check again but i believe the slab will be min 4" with mesh in the slab in rebar in the footing and stem wall.

this will be a stick building. i was looking into metal but then i would have to have it as a stand along building which will cause me to loose about 250sq/ft because i would not be able to build it off of the existing shed.

i was thinking the same thing but really i had nothing to compare to. i'm still waiting for one more estimate. if you know anyone please let me know. idk how much i was expecting it to cost but def not this much. i figured it was as simple as a building can get.

Why such a flat roof where it rains and snows so much?

And the snow/rain is going to cause issues of the little gambrel roof shed and the wall of your new building being trapped there.

 

[supratreo]

its doesn't snow here at all. rain yes but I'm assuming the architect, engineer, and city took all that into account. they designed a cricket into that space where the shed roof meets the new building. that's something that would be constructed on site I'm assuming it would be the same slope as the roof but really we can do a greater slope if needed. there's nothing specific in the plans.

Almost every-time I have seen roof slopes end at a wall there is water damage as a result. The water has such velocity and momentum that it hits the cricket or valley and splashes up and under the siding. It is hell to flash well enough to protect the wall assembly.

And all those roofs were 4/12 or 5/12 not a nearly vertical gambrel roof that will have even more velocity.

Furthermore I feel your trust in the architect and city building department is mislaid.

Building design failures are prevalent and common even with when done by professionals.

 

[Adaylate]

I don't agree with the logic of attaching the shed to the new building, but if you have to.........
Could you reconfigure your shed roof with rafters from the peak of the gambrel to the top plate area of your new buildong?
Good luck with your project!

 

[supratreo]

Thank you for the input guys. I was planning on having a roofer do the cricket as I've never done that but I think I will get it signed off as is and then just do what Adaylate said and have it connect from the shop roof to the shed roof

 

[supratreo]

actually, thinking about it some more i think I'll just make the change during construction. i don't see how the inspector can have and issue with that.
i was also going through to get a list of materials and noticed that the walls are shown as 16'. originally this was the idea but then changed to 14'. the engineer told me he'd be able to write a letter stating that the change would not make a difference for the load calcs and its safe to proceed with 14' walls.

If you have room to build a separate garage instead of an addition I would leave enough space between them to park a vehicle or a trailer. You could still plumb the compressor to the shed, it would eliminate the roof trough, and it would look a lot better than joining dissimilar structures

thats the problem, i don't have any extra room. this space in between my 2 car garage and shed is all i have so i didn't want to waste any space. i would have built off the 2 car garage but that would have been a whole different can of worms. i know looks wise its not the greatest design but having the most shop space i can is more important to me.

 

[rwreuter]

Recommend that you pay someone to do the concrete and framing....that is a large project.

 

[supratreo]

thank you. still looking for estimates. the other contractor sent me a follow up requesting $1500 for an estimate (which would then be put forward towards construction) but ya i'm not paying that.

Get your concrete guy finished up and build it yourself. The only tough part will be getting 12' walls on a 2' stemwall. I did that by myself in 1977 by using short sections of wall and pushing them up with 2x4's with one nail so it could swivel. A house I just built had 20 ft walls and I used a scaffold tower and winch on wheels. Worked like a charm and was safe working alone. Just had the scaffolding strapped together so a wind wouldn't surprise me.

Work at your own pace and get friends to help. You can always find new friends.

thank you very much. i have plenty of manpower and time is not an issue.

also, we originally planned for a 16' ceiling but changed it to 14'. with all the back an fourth with the city/designer/engineer somehow the original drawings got in there and that was approved. shouldn't really be an issue to have it corrected but now i'm thinking i'm gonna stick with the 16' (14' wall on 2' stemwall).
i do plan on buying a 19' or so (used) scissor lift as it would come in handy around the property and my business and figured it would be a big help during this process.

 

[oldironfarmer]

My current shop is 16'. It's never been too tall.

A scissor lift would be great for setting up walls. Just pay attention, they are not designed for lifting loads so watch the capacity and potential for tipping.
