I am so exasperated at the moment I need to scream. I am a structural and misc. steel detailer. One of the things I draw is stairs. I have a renovation job which has a stair in it. We drew the stairs per the contract documents and submitted them for approval. The contractor in reviewing our stair discovered an issue and brought it to my attention. I suggest he make his notes on the approval drawings and I would correct them after receipt of approval. He insisted I revise the stair and resubmit it for approval. I did as requested wasted a couple of hours. 3 days later I received revised drawings which altered the stairs considerably. About an hour ago I finally got the stairs completely corrected and was getting ready to put the stairs in the shop. I just received an e-mail which lowers the floor height by almost 5 inches. I now have to re-draw the stairs again. I want to strangle someone.
