We have always encountered weight differences between EST and CAM reports. We noticed that this difference seemed to be greater when there was liner on the particular take-off. When our EST was setup, no weight was assigned to any liner material because we price it by the sq. ft.. We have now assigned all of our liner material a weight of .0001 pounds per sq. ft. When we did this, all of our material weights now reflect only metal weight. We varified this by multiplying area from the report by the weight per sq. ft. of each metal gauge. Has anyone else experienced this problem, and is there another fix?
