I'm working on a parking deck project and due to a precast mishap the door to the stairwell/elevator lobby sits in a concrete wall opening that is 1 inch higher than the landing surface. My thought was to use one of those aluminum threshold-style ramps at the base of the door to allow a smooth transition down to the landing. Only problem is the code would require a level landing at the top and bottom of the ramp for maneuvering/etc. I really want the ramp to just go right to the base of the door similar to any other threshold arrangement. This ramp is all of twelve inches long, do I really need a top landing?
Before you suggest grinding down the concrete, we've already done that. Originally the difference in elevation was 2 inches. We got it down to 1 inch and we can't grind much further.
