No Columns for Overhead Doors
There are a few clients out there who leave parts of one or more walls open, with the idea of enclosing them at a later date. Most often this is done with the idea of being able to save money, however it is not always much of a money saver, especially if done wrong.
Here is just one example of why fully enclosed is a bargain compared to three sided: https://www.hansenpolebuildings.com/2014/03/three-sided-building/.
Reader NATHAN from MOUNT VERNON writes:
“I have an existing pole building that is 36 by 36 (12′ spacing on all columns) and is 16′ at the front, 20 at the next column back, 16 again at the second column and 12 at the rear of the structure. It is only sided on two sides (back 12′ wall and one side). I’m looking at finishing the building out with three 14ft doors on the front, but no columns were installed for this purpose. The concrete poured for the existing columns will prevent me from having proper footing if I put in new columns as in a new build. Can I bolt the new columns to the existing ones (Blocking and 5/8’s galvanized threaded rod) and have the bottom in a post base of suitable size and strength. As there is no concrete floor in the structure at this point I was also thinking of increasing the slap thickness in these areas and adding rebar. Your help is greatly appreciated Nathan.”
Nathan happens to be in a part of the country which requires Building Permits for most everything. At some point in time he is going to have to have a Registered Design Professional involved (RDP – architect or engineer) as his Building Official is going to want to see an engineer’s seal on the plans for the remodel.
There are numerous possibilities the RDP may take for a design solution. To keep in mind, these columns will be supporting no roof load, so it is merely a case of having them be adequate in size to resist wind loads, as well as the door itself.
While Nathan’s idea probably works, it might be easiest to mount the columns needed for the overhead doors into appropriately designed column brackets: https://www.hansenpolebuildings.com/2012/01/concrete-brackets/. A header can be run from one roof supporting column to the next to stabilize the top of the columns.
Before getting into a situation such as Nathan’s, research all of the options available. You might be able to enclose the building fully for little or no extra investment. As another alternative, financing is available which (with moderately reasonable credit) could allow some or all of your new building to be funded from a third party source with affordable monthly payments.
