An exterior prefabricate metal stair layout is shown adjacent to concrete tilt-up panels, with a note requiring the contractor to provide shop drawings prior to prefabrication and paint to match the building. The plan details six treads at eleven inches with specified running dimensions, a five-foot-six-inch overall width, and a door opening at the lower landing. Notes specify adjusting the number of treads and riser height per finish grade at each location per civil drawings, ensuring every step rise is between four and seven inches and the tread is not less than eleven inches per CBC Section 1011 and 11B-504, and providing non-slip surfaces on all treads.
