I have a large auto-body repair shop in Council Bluffs, Iowa. It is a steel building with heavy structural steel beams spanning large distances. Our business has been growing rapidly and I planned to put an addition onto the existing steel building. After visiting with the local building officials I learned that I would have to update other parts of my building to meet the current codes regarding fire prevention, etc. if I wanted a connected addition. The cost for the updates seemed prohibitive so I investigated what would be required if I placed a new free-standing building on the property.


I learned that no updates would be needed to the existing building if I kept the new building at least ten feet away from the existing body shop. So we began our planning on that basis. Our new building is 30' x 42' and will be used for paint-prep, painting and buffing. We started construction the first week of September 2011.

After reading about lightweight steel garage kits on garagetips-101.com, I investigated the cost for the building size we needed and learned that the labor and materials alone for the superstructure would be far less that just the wood materials if I built a wood frame structure. That was not counting the cost of labor to erect the wood framing.

I proceeded to have the initial site-prep work done and then contracted out the concrete work while I was negotiating the steel and erection package from two different fabricators. The city building officials allowed us to to use a simple reinforced concrete slab with no frost footings. The frost line in the Omaha-Council Bluffs metro area is an average of 42". They did require us to place a 12" x 12" concrete pier down 50" at each of the four corners of the building with steel reinforcing that tied into the slab. This requirement was so that we could anchor down the four corners of the lightweight steel superstructure to resist heavy wind loads and uplift forces.

I placed my steel building kit order the day they poured the concrete slab. One week later the steel arrived along with a local erection crew and within four days they had the superstructure up, the steel siding and roofing on, and were finished. The electrician started his work right away and I had one of my shop workers start installing two 1" thick layers of rigid foam between the vertical steel structure that consists of 2" x 2" square tubing. The city is requiring that we place 2 layers of x-rated (fire-rated) gypsum board on the wall that is 10' away from the existing building. You can see that in the photo labeled Interior View #2.

To heat the new building I used gas-fired radiant troughs that run the full 42' length of the building. One trough right down the center. I learned that the State of Iowa Fire Marshall has banned any further use of flexible gas piping throughout the state due to homes that have burned down due to the inclusion of it. I guess it is a lightning hazard. So we used standard high-ductile black piping with threaded joints and stainless steel flexible gas piping to make the final connection from the black pipe to the radiant-heat fixture. The local codes limit this to 3' feet in length and it must remain visible at all times.

I plan to have the building finished by early November so I can place a new paint-booth into it and begin using the old paint space for more repair bays in the original building.

The total cost for the concrete, steel and erection package, heat, electrical, insulation and drywall will be just a few cents below $28.00 per square foot. This will not include a high-end fire-sprinkler system that will go inside the paint booth. That will cost $3.50 per square foot and the paint booth is 14" x 26". After everything is finished I will be in the building at a very reasonable cost due to the efficiencies of the steel building kit.

I checked with Karl at Council Bluffs Collision Center about the cost of the fire suppression system and he stated that the $3.50 per square foot covers only the fire suppression system and not the paint booth itself.

He explained that the paint booth is a separate building that sits inside the main building and he already has it. He has to disassemble it from inside his original building and move it into his new building for re-assembly. Then he has to have a new foam-based fire suppression system installed in it.

He said the cost for a two-headed system for the paint booth is about $1,300.00 which works out to about $3.50 per square foot of just the paint booth square footage.

I hope this answers the question from Anonymous.

Booth question for Karl
by: Anonymous

Karl, you mentioned the following:

This will not include a high-end fire-sprinkler system that will go inside the paint booth. That will cost $3.50 per square foot and the paint booth is 14' x 26'

Does the $3.50 per Sq Ft cover the fire protection unit only, or the booth too?

Thanks!

Square Foot Cost
by: GarageTips-101, Editor

Thanks to Karl G. of All Makes Collision Center for sharing his story! The $28.00 per square foot total project cost is exceptional for the amount of space enclosed.

I spoke with Karl about the cost figures and he said that he spent $7800.00 on site-prep and the concrete work. The steel building kit erected cost $12800.00 including delivery to Iowa from Georgia. That portion of the project works out to be $16.34 per square foot. The remainder of the costs cover electrical, heating, insulation and wall finishing. It also covers a curb cut and driveway approach from the public street.

Karl did tell me that he was going to remove the roll-up overhead doors and replace them with insulated steel upward-acting doors with operators from Overhead Door of Omaha. He said the doors that came with the steel building kit package allow too much air and dirt infiltration through their joints which would be detrimental for a paint and prep operation.

Overall, Karl has shown that with a bit of ingenuity you can enclose a lot of square and cubic feet for a very reasonable cost with a safe, durable structure type.

Karl also said he would post up some of the unique construction details for the one-piece steel frame on our Steel Building Kits page in the near future. I am looking forward to seeing those!

Steel Building Kit
by: Rick

For the price, and in the short time that he built his steel garage in I would say that the steel garage kit he purchased rates right up there at one of the lowest cost garages you can get. Just under $28.00 a square foot.

The 28.00 a square foot price with concrete, electrical and radiant heat has got to be about as cost effective as you can get.

From his pictures it looks like the walls and roof frame is square tube for the structure and steel panels for the outside and roof.

The purpose that he is using that garage for looks like it will be perfect for automotive paint work and car clean-up.

I am looking at garage plans right now and I am considering a prefab Steel Building Kit for our next garage build.

I think from the research I have been doing online
that these building kits are something we are seriously looking at.
