To locate the north face of the column you have to look for the green moss.
I had one erector put the building up 180 degrees out of sync with the drawings. Then he couldn't figure out why the building had a large overhead garage door opening toward the "lawn".
Back in the "70's" while I was working in Mississippi I had a self standing elevator tower that tied into the building at the tenth floor. They couldn't get it plumbed so they told me, "Hey Yank, go plumb the tower, the other ganged said they had problems with it."
So I asked for a set of drawings so I could check the steel. "You don't need the drawings to plumb the tower, just put a couple of cables to it!" was the response.
I checked the tower with a transit and saw that it was 6 inches out of plumb. I figured if the other gang had problems, it could be that there was a couple of mislocated pieces causing it to be so tempermental. I went into the office during lunch and pulled the drawings. Low and behold, half the members were in the wrong locations. When I mentioned it to the foreman his reply was, "They're all the same, it don't matter!"
I asked him if they were all the same, why did they have different piece marks?
After two days of changing out the iron and relocating the members to the right location, the tower nearly sprang into plumb! Funny how that work!
By the way, is there an easy way to shrink/scale the embedded sketches so it is visible without having to move the cursor across the page?
