Pole Building Process: There are many steps in the building process. Here are the steps involved in a pole building garage being built.
Working with the homeowner, the builder lays out the building location and marks the post holes.
A skid loader with an 18" diameter auger digs holes 36" into the ground for the posts. The building materials sit nearby, ready to be used.
Posts are set into the holes on top of an 8" concrete footer. The posts typically are spaced 8' on center and serve as the foundation of the building.
The posts are tied together by 2x4 lumber running horizontally (girts). At the top of the posts on the eave sides are the carriers, usually yellow pine #1 lumber, which supports the weight of the roof trusses. Engineered trusses are tied together using 2x4 lumber (purlins).
Once the framing is complete, items like double bubble insulation / vapor barrier (seen here on the roof), windows and personnel doors are added.
The framing is complete, accessories added, overhead door openings (front eave wall) are done and the building is ready for the roof and side metal.
The roof metal, fascia trim and rake trim are installed. The ridge cap goes on top at the peak to close the roof in.
With the roof metal on, the 12" vented soffit (the white trim under the edge of the roof) is put in place. This gets the building ready for side metal.
The side metal is installed using matching color steel screws tying into the wall girts (2x4 running horizontally.) Overhead door trim (the blue metal inside the door openings), corner trim and base angle are installed to finish the side metal.
The builders are done! Framing, installing roof / side metal and all the accessories and trim are complete and the building is ready for the next step.
This is what the building will look like on the inside. The posts, girts and roof trusses are all visible from the inside.
This is where the sod / topsoil (usually about 4") are removed and the backfill is put in place. The backfill, usually a "select" sand-soil combination is brought in and packed down in preparation for the 4" concrete floor.
The backfill is compacted up to the bottom of the treated skirtboard. On top of the fill, a plastic vapor barrier is installed to keep moisture from getting up into the concrete. The metal bar (control crack) is used to control where the concrete will crack.
The 4" concrete floor has been poured along with a 2' apron outside the building at the overhead doors. There's also a pad on the outside at the personnel door.
Once the concrete is complete, the overhead doors and weather strips can be installed. With some outside grading (usually done by the homeowner) the building is ready for the final inspection, to receive the certificate of occupancy.
The building is complete, ready to be used!
