The builder just stopped by work to pay for an oil change he had done yesterday, and stopped in to discuss a few items with me. Supposedly the "bumps" in the tin have been remedied. I honestly haven't seen the building in the daylight for a few days so I have no idea! He said they pulled the tin and found some of the staples for the typar were causing the bumps. Apologized, for not being there to supervise, and assured me that it was good now. Hasn't replaced the tin that was scratched yet, but did say that it would be done. Supposed to hang five LED light fixtures today, and wants me to go check them out this evening. These fixtures are new to him and hes unsure of how the light is going to be. Just hanging them on the north side first, so that we can decide what to do about door interference on the south side. I think it is just something that we are going to have to deal with. He's concerned that with the doors up we won't have enough light on the south side. I think that it's just something that you have to deal with. I would rather have great light in the winter time with the doors down. Talked with him about the ceiling, and really it came down to that was his personal preference. He said initially they had talked about doing one solid 40ft panel, but decided to split it into two 20ft panels because they didn't think that they could make it look good spanning one piece 40ft. As far as the purlins, he just feels that it helps strengthen the building. He said he doesn't prefer to screw the tin directly to the trusses. Again, I think it's just what hes always done, so that's what he does. The more I look at it, the more I like it. As Eddie stated above, it just seems more inviting when you walk in the building. I may not have ever noticed had it not been mentioned. Told him I was going to enjoy a cold beverage in there this evening, and he suggested a couple so that I could really take the time to check out the light.
