Assembly of the two gable ends, the double rafter Center section, and side rails can be easily assembled by one person in a garage or shop setting and on a work table with space all around to complete the bolt ups of the posts and tails. The assembly instructions are quite easy to follow by most people and moving  the sections to the  concrete pad for tilt up and connection is possible by two people but three people is recommended for tilt up. Note: Organizing all the numbered posts, numbered rafters, rails, brackets, nuts, bolts, etc. beforehand is highly recommended to avoid errors.

Assembling the wooden roof sections was also easy to install in a shop but squaring the roof panel section within the allowable tolerance was difficult, although the holes were pre-drilled. I would prefer to install the metal panels after the wood frame was in place on the roof to ensure it is squared with the erected structure.

Roof Cap needs a better design.

Provide more screws, nuts, bolts, etc!!
