To determine the number of steps required for a stepped foundation on a sloped grade, one needs to consider the overall height difference between the front and the rear of the foundation. In this case, the elevation difference is 1,000 mm (39 inches).

Typically, the height of each step in a stepped foundation is standardized, often around 200 mm (approximately 8 inches) per step. By dividing the total height of the foundation (1,000 mm) by the height of each step (200 mm), you arrive at the solution.

Calculating this gives:

1,000 mm / 200 mm = 5

This means that you will need a total of 5 steps to accommodate the 1,000 mm height difference, ensuring the foundation is built correctly for stability and drainage on the sloped land.

This method not only provides an adequate transition between levels but also ensures compliance with building standards, which usually dictate step sizes for safety and structural integrity.
