An overhead door opening in pre-engineered bldg

An overhead door opening in pre-engineered bldg

An overhead door opening in pre-engineered bldg

(OP)
The plant is trying to cut a wall at the side of building (Metal Pre engineered bldg)for an overhead door (approx. 20' x 20').
Seems the walls are siding. Tomorrow I am going to field may I ask if anyone can direct what should I look for?
We did not find drawings.
What measurement and what things I need to pay attention and take measurement?
I appreciate the guidance.

The location of door will be at the side of building -end bay. Do know any advantages and disadvantages about the location of door?
What should I design?

Thank you

Do not cut or remove any existing rod type "X" bracing to install the door.

Do not cut any end wall wind columns.

Only remove horizontal purlins and siding.

RE: An overhead door opening in pre-engineered bldg

Offhand:

Presence of any bracing or other structure that might be in corners
Clearance for required door opening
How new door is going to be hung (structure wise - columns and beams)
clear distance to ceiling from top of door
Clear distance from opening to adjacent walls
Space required for opener (torsion springs, motorized opener, etc)
presence of electric, water, or gas utility lines

try and get dimensions for things you might not even think you need. I always kick myself in the pants later because there was a dimension I thought I didn't need but would be useful later.

take pictures with a half decent camera. Take zoomed in shots and zoomed out shots.

RE: An overhead door opening in pre-engineered bldg

ditto to mike's comments. If the overhead door fits within the end wall without requiring x-bracing or columns to be cut then it is fairly quick and painless. If the only way to fit the door is to modify one of those items then you'd best try to get the pre-eng company involved.

If you're lucky, you can find out the original supplier, they're still in business, they answer the phone, they haven't lost the calculations (warehouse fire in Des Moines) and business is slow in the PEMB sphere, they might be helpful. But echoing all the advice above, don't do this yourself.
These buildings do fall down and if they have a unapproved door cut into it, that's what they use for an excuse. If there is no door cut into it, they go to excuse two.
