A: The hallmark of modern post-frame construction is the primary structural frame that typically consists of a clear span truss supported by two columns. This primary framing system is supported by an interlocking system of purlins, girts, and sheathing. Loads are transferred to the ground through columns typically embedded in the ground or surface-mounted to a concrete or masonry foundation.
The term pre-engineered post-frame is a modernization of the outdated term "pole barn." Today's post frame systems have been infused with leading edge technologies and, as a result, this enduring approach is now regarded as the most efficient approach for today's modern building requirements.
A: Compared to other building methods, post-frame is often the faster, more efficient alternative. However, less expensive doesn't mean "cheaper" quality. In certain applications, especially structures larger than 20,000 sq. ft., other building methods may become more competitive.
A: Absolutely. Almost any amount of design customization can be accommodated. However, we suggest that you supplement your design with input from a builder just to make sure that all issues are uncovered and that your building makes optimum use of pre-engineered efficiencies.
A: This ranges by time of year and type of building - usually it's about five to seven weeks but in many other instances three or four. However, in peak construction season lead times can stretch out to six to ten weeks.
A: Extremely. The "diaphragm" building concepts inherent with post frame construction are proven and time tested.
A: For most components, southern yellow pine, simply because of its superior fastener holding capacity. In addition, with a few exceptions, Machine Stress Rated (MSR) lumber for top/bottom trusses chords.
A: Yes
A: Yes. However, since a construction crew is not involved in a purchase of this kind, the purchaser assumes responsibility for all of the warranty obligations that would ordinarily be undertaken by the builder, including completing the construction in a workmanlike manner and in conformity with established industry standards.
A: Columns are multi-ply (2 X _), laminated #1 Southern Yellow Pine. A big advantage of this design is the ability to effectively treat the entire column section resulting in long life. Another distinguishing feature is the optimum use of "longest-possible" lumber to reduce the number of splices, which adds strength. The result is industry-leading strength - with bending capacity of up to 60%, superior to solid 6" x 6" posts and other column configurations.
A: For the basic finished "shell" (framing and sheathing) the time required depends mostly on the size, type of building and the amount of interior and exterior customization. Generally speaking, this can run anywhere from four days to a few months.
A: This refers to buildings with the distinctive gambrel roof in which a two-angled slope is applied to the roof pitch - with the first (starting at the roof peak) slope being more gradual than the second. This configuration gives the roof a more barn-like appearance.
A: Specifying a gambrel roof system adds about 15% to 25% cost compared to a building with a standard roof/truss system.
A: Yes. If standard windows or doors (or any accessory for that matter) do not meet your needs, you may special order.
A: Not necessarily. For instance, one very popular framing system, features columns set in the ground, allowing for year-around building. This system works even when you decide AFTER the building is finished, to have a concrete floor added.
A: Just about any structure can be modified to feature a rafter-style roof system which usually means a few engineering modifications to properly accommodate design loads. Consult with Ivanrox Construction.
A: Generally speaking, around 80'. However, with some design modifications, it is possible to stretch the "clear-span" envelope on structures to 100' or more in width before interior columns are needed for support.
A: No, roof material may be asphalt shingles, wood/cedar shakes, metal standing seam or any material that can be screwed down to any flush purlin system.
A: Yes, many structures are finished with traditional masonry. However, we recommend using more efficient "faux" brick options such as the Moderra "mortarless" systems.
A: A treated 2" x 8" board that acts as a nailing surface for wall sheathing at ground level.
A: A type of metal architectural roof system known for its distinctively stylish appearance and highlighted by regularly-spaced raised seams or "ribs." The clean, bold lines of the standing seam roof system lend themselves to accomplish the highest levels of appearance.
A: Basic ag structures are 9’ on center. Code buildings are 8' on center or 6’ depending on snow and wind loads. However, engineering software may determine that the most efficient building for your needs is a variation of these standards.
A: 2' – 4' square. However, custom size cupolas are also available.
A: Unless otherwise requested by the customer, color-matched screws are standard.
A: 12" and 24"
A: A 4:12 pitch is standard. Any pitch can be accommodated.
A: This answer varies a great deal all across the United States, it's best to consult with your local building department to determine the load requirements for your specific area.
A: 4" to 6"
A: This is a very minimal extra cost that can make a huge difference in your building's appearance - about $3 per lineal foot.
A: Available in aluminum and vinyl frame, insulated and un-insulated
