I'm wanting to add a garage door to my existing carport which is block construction. The home was built in the 50's and the cells around the opening are not filled with concrete. Additionally, there is no block header, just a wood header spanning the top of the opening. The city is requiring a detail of attachement that meets wind load specs. I need to be pointed in the right direction for submitting a plan and actually engineering the opening and a header that matches the height of the door itself??
Thanks in advance - SP
