Building a Tricky Staircase
What happens here
Begin by assessing the project area where the stairs will be installed. Use an excavator, specifically a Bobcat mini-excavator, to remove the existing soil and create the initial trench for the first stair tread. This excavation should be approximately 38 inches deep to accommodate the base material and the stair unit. Use a wheelbarrow to haul away the excavated soil. The depth for the first stair is critical as it sets the grade for all subsequent steps.
Goal: Create a properly sized and sloped trench for the first stair tread.
