a BONUS PBG for Friday, May 31st — Column Spacing, Raised Floors, and a Self-Build
DEAR POLE BARN GURU: I have spoken to my architect and he is saying to do my column spacing 8′ with truss every 4′. I have looked at your videos and several other videos. I noticed 10′ or 12′ Columns with double truss is more than enough. This is going to be my house for now and later turn into my garage when my actual house it built. The size is 30x60x12. Also I will be using shingles for my roof since my HOA doesn’t allow metal. I am wanting to be efficient and save money but also have this built safely. ANGEL in SEALY
DEAR ANGEL: In our country, there are several places where post frame standard is just as your architect describes, however this is not necessarily most efficient for use of materials, structural sufficiency or ease of construction. We have provided roughly a hundred fully engineered post-frame buildings to our clients in Texas and I can assure you, columns every 12 feet with double trusses works admirably. While shingled roofs do not have longevity like steel roofing, we have clients who opt for this option.
DEAR POLE BARN GURU: I read your article about raised floors in post frame homes. I live in a flood prone area an was considering something like this. Do you have any other information or details? https://www.hansenpolebuildings.com/2018/03/raised-floors-post-frame-homes/ SEAN in PRAIRIEVILLE
DEAR SEAN: Thank you for your interest. One of our team members will be reaching out to you shortly, as we do need some very specific information in regards to your building site. This will include actual elevation of site, as well as your potential flood data.
DEAR POLE BARN GURU: Hey there! I’m wanting to self build a 50×70 or a 48×72 which is probably more cost savings. 16′ height and I’m leaning towards 10′ spacing. It’s a 3 sides equipment storage building. One of the 70′ sides being open. I need any help you can give on post spacing, 3ply or 4ply , truss spacing and a double header if I’m not locking into the post with the truss because the spacing won’t allow. I’m open to any suggestions. ERIK in SEYMOUR
DEAR ERIK: We do offer a 5% discount on buildings with multiples of 6′ in width and 12′ in length (read more here: https://www.hansenpolebuildings.com/2024/04/13-can-be-very-fortunate/). You will probably find columns every 12 feet on your open sidewall to be most ideal for equipment storage – as trying to maneuver even a full sized pickup or SUV through 9’8″ between posts can prove a good way to lose a mirror. Our typical engineered design is going to place trusses directly aligned with columns, so dealing with headers between columns becomes a non-issue. Your Hansen Pole Buildings’ Designer Cory will be working with you to make sure you get your best possible value for your investment.
DEAR POLE BARN GURU: I plan on putting up a 60′ x 120′ post frame shed. I’m going to run my 6×6 posts at 8′ o.c. can I use all 8′ 2×6 material for the girts or should I have some 16′ material staggered in with the 8′ material? Will that increase the strength or do you think it would be similar? Thanks guru! JASON in NEW HOLSTEIN
DEAR MATTHEW: Having built for myself an elevated floor post frame building (I had 14 feet of grade change in 24 feet), I feel as though they are a great solution. Unless you had enough grade change to practically utilize space below, I would use interior columns to reduce spans of beams and joists – little, short columns being far less expensive than large multiple ply beams and large dimension floor joists. My knees also prefer to live on wood, rather than concrete – making this a double win.
DEAR SHARKBITE: In order to determine if your trusses can handle weight of this unit, you would need to look at your engineer sealed roof truss drawings. If Bottom Chord Dead Load (often shown as BCDL) is less than five (5) psf (pounds per square foot) then probably not. Ideally, reach out to whomever fabricated your trusses. Give them weight of your unit, where you propose to hang it, as well as if you have a ceiling and insulation and they can give you a definitive thumbs up or down.
DEAR POLE BARN GURU: Do my tracks for garage door mount directly to the 6×6 posts, or is there a 2×6 supposed to be added to mount to? DAVID in ROCKFIELD
DEAR KAYA: Yes, Hansen Pole Buildings delivers to Massachusetts as well as all 47 other contiguous U.S. states. For Alaska and Hawaii, we will deliver to a West Coast port (most usually Tacoma) for loading onto a container contracted by you.
DEAR POLE BARN GURU: Does the estimated price of a Pole Barn include flooring options, or is that extra? DAVID in MAPLE GROVE
DEAR POLE BARN GURU: Do you have a kit that can be used in a flood area to raise floor about 10 feet. RAY in HOUSTON
DEAR WILL: Congratulations upon considering post frame construction as your structural design solution. Sadly, most kit providers and builders are selling building shells based upon cheapest price, rather than meeting their client’s needs. With this low price, most often comes what is known as externally mounted wall girts – wall framing to support siding being attached wide face to wind on outside of columns. While this is quick, easy and takes little thought, it rarely meets Building Code requirements for meeting deflection criteria. There is a way to solve wall framing to be a one step process – bookshelf wall girts every 24 inches. This creates a very stiff wall structurally, provides an insulation cavity and requires no extra framing to add interior finishes.
DEAR STEVE: If you place a 2×4 vertically in a hole and push downward on it and it just keeps sinking, you have a challenge going on. Your best solution then is going to be to hire a geotechnical engineer to visit your site and do a determination of how to adequately support your building based upon actual soil conditions. It may be able to be solved by use of larger diameter footings, or use of rebar within your slab (tied to columns), piers down to solid bedrock or some combination of these. Your building will only be as strong as your foundation, so this is not a place to mess around or guess.

DEAR KIM: Your local Planning Department director gave you good advice. Most post frame (pole) buildings are designed for Risk Category I occupancies (if they were designed at all) – meaning if they collapse chances are good no one will be in them when it happens. They use lower wind and snow loads than what is required for residential purposes.
