NMDOT PARTS CATALOG – PART 2

DEVELOPMENT REPORT

and the user will use the correct bid item number based on the heights the user sets. For example, Figure 11 shows the rim elevation and sump elevation in C3D as controllable parameters.

The custom structures come from the Standard Drawings and include the Standard Drawing reference in their name to help the user identify them. Because embankment slope is not a parameter that C3D recognizes as being associated with structures, the slope blankets are further organized by specific slopes. The slope options are taken directly from the Standard Drawings. To eliminate the number of duplicate structures that have the same basic dimensions and layout, slope blankets with safety grates and slope blankets for High Density Polyethylene (HDPE) pipes were not added to the catalog. This is because the general slope blanket can be used for all those cases since the dimension of the concrete does not change. Adding the safety grate would provide too much detail for a general NMDOT pipe network catalog. Skews also were not modeled for these end treatment structures. This omission is due to complexity with modeling slope blankets at different skews and limitations with C3D identifying those skews. The concrete and metal end sections dimension are also taken from the Standard Drawings but were verified with the products available in New Mexico. Additional custom structures may be added later by the NMDOT. Some structures were not added because they were not included in the Standard Drawings, as discussed in Section 4.1. 3.3 STYLES Styles for pipes and structures were updated to supplement the NMDOT’s AutoCAD C3D 2024 template. For pipes, styles were created for existing and proposed conditions. Each condition includes styles for concrete box culverts (CBC), drainage pipes (CC and SD), and sanitary pipes. Each pipe type includes two styles, crossing view and longitudinal view, for a total of twelve styles. See Figure 12 for a complete list of pipe styles. Crossing view styles are to be used when projecting pipes into profile views that cross center line alignment. Longitudinal views styles are to be used when projecting pipes into profile views that run along the center line alignment.
