Why Not a 2×6 Bookshelf Girt on a 4×6 Column?

Why Not a 2×6 Bookshelf Girt on a 4×6 Column?

Client TROY in MONROE COUNTY writes:

It was my understanding that 4×6 posts were used, so a 2×6 girt could be mounted flush on the inside of the building and extend 1.5” beyond the post at the outside of the building. Why can’t exterior and interior sheeting be applied to the 2×6 girt?  What is the advantage of the 2×8 girt?

Are the rafters spaced at 12’, is that the need for 2x10s?

If they’re set on the same post as the truss, is there room?  5.5” post minus 3” for double truss leaves 2.5”.  Do you take away 1.5” for the rafter leaving 1” of post?

Feel free to call if it’s too much to type

Thanks”

Thank you for being an inquiring client, those who ask lots of questions are those who get results they are happiest with!

On a 14′ sidewall, truss bearing columns are unlikely to work as 4×6 due to failure in weak axis bending (they want to buckle due to compressive loads from dead loads and snow). So now we are into either 6×6 (or in some cases larger) solid sawn columns, or glu-laminated columns for truss bearings.

Couldn’t 2×6 bookshelf girts be used and be flush to both sides of these?

With 6×6 columns, they do tend to vary in dimension – sometimes as great as 1/2″. This would potentially result in columns sticking outside of plane of a 2×6 bookshelf wall girt, making finish on one side problematic.

More importantly (and less recognized by most providers) is pressure preservative treated splash plank at base of enclosed walls must be attached adequately to transfer wind shear loads from roof, down through wall sheathing (steel siding), to splash plank, then to columns and into ground. Greatest forces are at the top and bottom of walls. When splash planks are applied to the exterior face of columns, it allows for appropriate connectors to be placed from splash plank to column to provide a continuous load path. 

Other members (such as overhead door headers and window supports) are also best installed on exteriors of columns (they transfer shear loads as well).

To hide columns and provide for space occupied by exterior fastened members, 2×8 bookshelf girts work nicely in combination with either a 6×6 solid sawn or multi-ply 2×6 glu-laminated column.

This also allows for a deeper wall cavity, hence greater thicknesses of insulation may be utilized. I would consider using two layers of 3-1/2″ Rockwool batts with a well-sealed interior vapor barrier.

While main clearspan interior double trusses will notch three inches into sidewall columns, rafters for your attached shed will be applied to column faces, rather than further notching of columns. With your roof loads, it actually takes two 2×10 rafters on each side of columns spaced every 12 feet.

Provided your site has adequate space, I would recommend you consider a 40′ x 48′ x 14′ clearspan building, rather than 28′ x 48′ x 14′ with a 10′ x 24′ attached shed on one side. It will be easiest to assemble, takes away a pitch break between main building and shed, eliminates an interior column and provides full headroom from eave-to-eave. This would also allow for those 8′ wide by 9′ tall overhead doors to be increased in width to 9 or 10 feet wide, keeping mirrors on vehicles. You will also find this to have far greater value for resale (multiple times more than any added investment).

Builder Warranty Example

Example Builder Warranty

Disclaimer – this and subsequent articles on this subject are not intended to be legal advice, merely an example for discussions between you and your legal advisor.

I cannot express strongly enough how important to both builders and their clients to have a written warranty in any agreement. 

WARRANTIES: There is no warranty applicable to the building and is expressly in lieu of all other warranties available under any State or Federal laws, expressed or implied, including any warranty of all labor, material, product and taxes will be paid for and there will be no potential lien claim against Purchaser’s property upon completion of the work and following final payment by Purchaser to Seller.

Products supplied by third party suppliers, manufacturers and sub-contractors to the project are warranted only to the extent that the suppliers and manufacturers of those products provide a warranty.

In the event that a defect is discovered in one of these products, Seller will assist Purchaser in securing repair or replacement of these products under the warranty provided by the third party supplier or manufacturer. Warranty work is work which was correctly and completely done initially, but becomes non-operational or dysfunctional following occupancy or use by Purchaser. No retainage or holdback will be allowed for warranty work.  

Seller expressly warrants to the original noncommercial purchaser(s) and only the original purchasers.  

That if any part of a Seller constructed post frame building, as covered by this warranty, proves to be defective due to materials or workmanship, under normal use and service, for two (2) years, that defective part will be repaired or replaced, subject to the terms and conditions contained in this Warranty.

Seller hereby assigns to Purchaser all rights under manufacturer’s warranties. Defects in items covered in manufacturer’s warranties are excluded from coverage of this limited warranty, and Purchaser should follow the procedures in the manufacturer’s warranties if defects appear in these items. 

 For ten (10) years.

Any solid sawn or glu-laminated (pressure treated to a minimum UC-4B) structural columns that fail due to decay or insect damage, unless said column has been exposed to animal wastes.

The original building roof structure, if damaged directly by snow loads because of the failure of any prefabricated roof truss or trusses to meet design specification. Subjecting your roof system to greater loads than those set out on the face of this Agreement, any unspecified ceiling loads, or modifying the trusses in any way voids all Warranties.

Any major structural defects which are defined as being an actual defect in a load-bearing portion of the building which seriously impairs its load-bearing function to the extent that the building is unsafe. For purposes of this definition, the following items compromise the structure of the building:

  1. Load bearing columns,
  2. Floor or ceiling joists,
  3. Beam, trusses and rafters.

For Two  (2) Years:

Any roof leaks due to defects in material or workmanship, expressly excepting where the building has been connected to an adjoining structure, in roof valleys, or at roof slope changes to which cases, no warranty applies. 

Any other building parts which prove to be defective in material or workmanship.

This warranty period shall commence on the date of the acceptance of the building by the Purchase or Purchaser’s occupancy of the building, whichever comes first.

This warranty contained wherein is void in situations where:

  1. Installation is not made in accordance with the instructions supplied by Hansen Buildings.
  2. The actual operation or use of the product varies from the recommended operation or intended use.
  3. There is a malfunction or defect resulting from or worsened by misuse, negligence, accidents, lack of or improper performance of required maintenance by the original purchaser.
  4. The building is altered or added onto, unless by Seller.
  5. Seller is not notified within twenty four (24) hours of problems due to snow loads.
  6. Purchaser fails to take timely action to or damage.
  7. Anyone other than Seller’s employees or agents or subcontractors have been on the building roof.
  8. Purchaser fails to make final payment per terms of sale.

Equipment such as fans, HVAC, gutters, downspouts, walk door locksets, other equipment not manufactured by Seller, site work, concrete, doors, windows, interior finishes, mechanical or electrical systems are excluded from this warranty.

The Purchaser expressly agrees to fully and timely pursue all available remedies under any applicable insurance agreement before making claim under this warranty.

In the event Seller repairs, replaces or pays the cost of repairing or replacing any defect covered in this warranty for which Purchaser is covered by insurance or a warranty provided by another party. Purchaser must assign proceeds of such insurance or other warranty to Seller, to the extent of the cost to Seller, of such repair or replacement.

Any claims for defects under warranty must be submitted in writing to Seller within the warranty period and promptly after discovery of the claimed defect, describing the defect claimed and date of building completion, before Seller is responsible for correction of that defect. Written notice of a defect must be received by Seller prior to the expiration of the warranty on that defect and no action at law or in equity may be brought by Purchaser against Seller, for failure to remedy or repair any defect about which Seller has not received timely notice in writing.

Purchaser must provide access to Seller, during normal business hours to inspect the defect reported and, if necessary, to take corrective action. A reasonable time should be allowed for inspection purposes. If, after inspection, Seller agrees, at its sole option to repair or replace only the defective materials or workmanship within the first three months from date of building completion at NO COST to the Purchaser. Thereafter Seller shall assume the cost of material and labor for any warranty work upon advance payment by the Purchaser of a one hundred dollar service payment for each incident under this warranty. The obligation of Seller, under this warranty, shall be performed only by persons designated and compensated by Seller for that purpose, and is subject to all other provisions of this warranty.

The provisions of this Warranty are the full and complete warranty policy extended by Seller, and are expressly in lieu of all other warranties, expressed or implied, including any warranty of merchantability or fitness for a particular purpose. These warranties may not be transferred or assigned. The liability of Seller shall not exceed the cost to Seller for repairing or replacing damaged or defective material or workmanship, as provided above, during the warranty period. 

THE WARRANTY STATEMENTS CONTAINED IN THIS LIMITED WARRANTY SET FORTH THE ONLY EXPRESS WARRANTIES EXTENDED BY SELLER FOR ITS BUILDING AND THE PROVISIONS HEREOF SHALL CONSTITUTE THE PURCHASERS EXCLUSIVE REMEDY FOR BREACH OF THIS WARRANTY. IN NO EVENT WILL SELLER BE LIABLE TO THE PURCHASER FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND FOR BREACH OF AN EXPRESS OR IMPLIED WARRANTY ON THE BUILDING; PROPERTY DAMAGE, PERSONAL INJURY , OR ECONOMIC LOSS IF OCCASIONED BY SELLER’S NEGLIGENCE, EVEN IF SELLER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other rights which vary from state to state. 

Purchaser shall promptly contact Seller’s warranty department regarding any disputes involving this Agreement.

Seller and Purchaser agree that this limited warranty on the building is in lieu if all warranties of ability or workmanlike construction or any other warranties, express or implied, to which Purchaser might be entitled, except as to consumer products. No employee, subcontractor, or agent of Seller has the authority to change the terms of this warranty.

Don’t Want Pressure Treated Columns in the Ground?

Loyal reader GREG in KENTWOOD writes:

“We plan to build a house next summer with basically (2) – 40’x60’ units connected at 90°, wife is still in the planning stage, 2 story.  I feel that me and my sons should be able to erect a kit with directions from the supplier and tips.   I like your website and the pole barn guru – FYI.

Here is my first question(s):

Since this project will be a house, on a slab in Michigan, which will require 48” depth of some sort of pole / wall / perma-column / piers like CRS system / Cedar post / other.

I really can’t put a treated pole in a hole and expect it to last 100 years, even with a plastic cover.  But I do not want to break my “bank” going overkill.

I also kind of like the idea of laminated posts above ground, which could be untreated if some method was used to get posts above the ground, which would also allow them to be shorter and reduce cost.

Might even like the idea of pouring cement at the base of each pole hole for better support then use a perma-column, instead of a cookie.  (Wish they did not cost so much, alternative?

With my concerns, what method would you suggest to use for the poles?

My wife should be done with the exterior plan in a week or so then I will send it to you for a quote. 

Thanks

Thank you for your interest in a new Hansen Pole Building as well as your kind words. We have assisted thousands of clients just like you to erect their own beautiful buildings – basically anyone who is physically able and can read directions in English can become a success story.

While properly pressure preservative treated lumber will last for generations embedded in ground (even without any sort of plastic sleeves), we recognize there are those, just like you, who feel far more confident with columns above ground. With this in mind, your least expensive and easiest to construct design solution will be poured concrete piers with wet set brackets embedded into them to attach your building’s columns.

With this option, we do account for your columns being shorter in length. We do recommend use of true glu-laminated columns in markets where they are logistically available as they are stronger and straighter than similarly sized solid sawn columns.

Poured concrete foundation walls with footings (and wet set brackets in the top of the wall) will be a budget buster. Nine years ago the cost of a single 40’ x 60’ foundation for a two foot frost depth was roughly $12,000 (https://www.hansenpolebuildings.com/2011/10/buildings-why-not-stick-frame-construction/).

Permacolumns (besides just their cost) can prove to be unwieldy (https://www.hansenpolebuildings.com/2018/04/perma-column-price-advantage/). They also would require a poured concrete footing beneath in order to adequately distribute roof and second floor loads plus building dead weight to supporting soils. Concrete cookies will rarely be adequate for even minimally sized buildings and loads.

Depending upon species of cedar, soil moisture conditions and amount of freeze and thaw cycles, it may last 15 to 30 years – so probably not a viable alternative.
