The pile shown in the image is divided into four sections marked in blue and red. Blue sections indicate gaps, while red sections indicate reinforcement. The gap in the row 1 input is marked as section 1 in blue. Section 2 in red corresponds to the row 1 input zone. The gap in the row 2 input is visible in section 3 in blue, and the reinforcement input is shown in section 4 in red. The transverse reinforcement used in the pile is symmetrical, so the opposite end will be a mirror image of what is depicted above.
Using Absolute Locations (Location Defined Input)
By enabling the "Use Absolute Locations" option, the interface will display a new grid that enables users to place zones according to a defined location. This location can be either from the top or bottom of the pile, and the program will visually indicate this by positioning the bottom of the pile on the left and the top on the right. The input for this option consists of four sections, including the pile location, the number of spirals or ties, the spacing between the ties, and the total length of the section.

The provided image above showcases an example input for the transverse reinforcement zone. As per this input, the first transverse zone will begin at 3 inches from the bottom of the pile, meaning this will start from the left of the drawings. The zone will consist of 9 ties or spirals, with a spacing of 1.5 inches between each tie or spiral. This arrangement will result in a total of 8 spaces, with a length of 1'-0". The visualization below demonstrates this configuration.

Every sequential zone should have a start location of the previous zones start location plus the previous zones length. |
In the given example, the second row of the pile starts at a distance of 1 foot and 3 inches from the bottom of the pile. This is because the zones of the pile must begin where the previous zone ended. For every other zone, the program automatically incorporates an offset to the previous zone without requiring any additional input from the user. For instance, if zone 1 ends on the ninth tie, then zone 2 will begin on the ninth tie. Since zone 2 is an even zone, it will include a gap with a length equivalent to the zone pitch. This gap will appear at the beginning and end of the zone. As a result, even zones will have a standard length of "Quantity" - 1 * "Spacing", with an additional 2 * "Spacing" added to their "Length" to account for the start and end offset. So row 2 will have a length of
(189 - 1) * 3” = 564”
564” + 3” bottom offset + 3” top offset = 570”
570” / 12” = 47'-6”
The image below displays the visualization of this configuration.
...
To continue with the previous example, the next zone in this input should begin at a distance of 1'-3” + 47'-6” from the bottom of the pile, which equals 48'-9”. This zone, denoted as zone 3, will use 9 ties with a spacing of 1.5”, similar to the first zone, and will also have a length of 1'-0”. To simplify the process, the zone can also be denoted as starting 3” from the top of the pile. Therefore, the input for zone 3 can be represented as starting 3” from the top of the pile and using 9 ties with 1.5” spacing, similar to the image shown above for zones 1 and 2.
