they didnt leave it out but the winner of the concrete probably wishes they did because he was, percentage wise, left WAYYYYY more than that 5 mil on the table which was about 10% or so of the job. Concrete dude was WAYYYYY more than that.
As for the estimator of the GC, the first comment when i got a call back happened to be from the #2 bidder, and he said i wouldnt have a job right now even if i could justify it to my boss and even if i was right...they would fire in spite. He said that guys ******* couldnt squeeze a bb through it. I concured, was told i wasnt low and was then told the low bid...i started lauging and said now THAT guys ******* is even tighter than the GC's. Crazy ****...
