First, determine the rise and run of the steps and marks these areas with landscape marking paint. The steps for this project have a 14-inch tread and a three-foot landing at the door.
Begin digging the area for the steps from the bottom so that there will still be ground to set them into. Then, tamp the area and place the step. Because these steps are very heavy, rent a compact utility loader for the day (Image 1), which costs about $150 per day to rent. A ball cart is also a good option for moving heavy round items like stones and root balls.
Use a landscape bar and shovel to maneuver the step into the exact position and check to make sure it's level (Image 2). Stack the next layers of steps, maintaining the 14-inch tread (Image 3).
