Estimating a Landscape Retaining Wall

Estimating a Landscape Wall
  1. Select the condition above the wall. You have the choice of a level grade, a surcharge less than 100 psf (4.8 kPa), or a slope no steeper than 3:1 (Run:Rise).

  2. Select your site's soil; you may select either sand or clay.

  3. Select whether caps should be included in the estimate.

  4. Select the number of courses of block. Notice that the overall wall height (not including caps) is given to the right.

  5. Enter the length of your wall.

  6. Click the Calculate button for your landscape retaining wall estimate.

Estimating a Commercial Retaining Wall

Estimating a Commercial Retaining Wall
  1. Select the condition above the wall. You have the choice of a level grade, a surcharge less than 250 psf (12 kPa), or a slope no steeper than 3:1 (Run:Rise).

  2. Select your site's soil; you may select either sand or clay.

  3. Select whether caps should be included in the estimate.

  4. The program is defaulted to automatically calculate the amount of buried block based on the 1 inch per 1 foot of wall heigh (25 mm / 305 mm) rule of thumb. To manually enter the depth of buried block, uncheck the Default Depth checkbox and enter your minimum buried block depth in the box provided. NOTE: If there is a slope below the wall, you must manually assign a buried block depth.

  1. Start entering your wall values in the chart provided.
    • Station - The Station is the running distance from the beginning of the wall. Typically the first station is 0 and each station thereafter is added to the beginning station. Add stations any time the rate of the grade change differs. The more stations you place in your wall, the more accurate the estimate will be.

    • Top of Wall - Each Station must have a Top Of Wall elevation. This is the elevation at the top of the wall, without the cap.

    • Grade - Each Station must also have a Grade elevation. This is the grade elevation at the bottom of the wall. Note that the Grade must be less than or equal to the Top of Wall elevation.



  2. Use the Up / Down arrows provided to add more stations and to scroll through the stations you already entered.

  3. Click the Calculate button for your commercial retaining wall estimate.

  4. To view and print the elevation and typical cross section, click the View Elevation button.
