heehaw - "i'd sure like to see what the pros drill the holes with to be able to put one of these babies up in an hour"
It was amazing! I video taped some of it. One of the requirements was that a 120V outlet was available close by. they plugged a long extension cord (heavy duty) into it that went to a multi outlet block. Then, they used heavy duty industrial drills (Dewalt) with nut drivers to put the screws in. They used self taping screws with rubber washers for everything. They were going so fast that the drills ran almost continuously! They would grab a hand full of screws and then go like mad. They would pause for a split second to put another screw in the driver and have it. The drills were set to a certain torque so they didn't twist off any screws. They were working as if their life depended on getting it done in an hour! They parked about 30' from the site and would run back and forth getting tools and supplies. It was a sight to see.
The only time they slowed down was to level up the frame after they put it together. They used metal spacers, made of the same material as the frame, and put spacers under one end (it was about 2 1/2" low, I knew it was off but didn't have time to do anything about it). They used a line level to level it up.
To do the roof, they got on step ladders on one side and laid the first panel (26' all one solid panel) on top and then pushed it to the top. Then, one guy got on top and screwed it down, except for the bottom edge. The guy on top stayed there until it was done. The other guy pulled another panel off the trailer, put it on his back, carried it over (about 30'), and then tilted one end up so the guy on top could reach it and pull it up. Then, they put the top edge of the new panel under the bottom edge of the one already there and screwed it down - again except for the bottom edge. They repeated this process until the last panel was on. I sure never expected them to go from the top down! The guy on top just walked around taking big steps to make sure he stepped on the frame rails.
The only bad thing about them was they were not very personable. They arrived with a pickup pulling a trailer and backed it onto the driveway from the road. The driver started to drive off the edge of the pavement with his pickup and I asked him to stop and straighten it out and I explained that it was new pavement and the pavers told me not to drive on the edge of it or it might crack it. He seemed irritated at my request. He could only speak enough English to get by and the other guy could not speak any English.
