# Box Culvert Template

The Box Culvert Template models cast-in-place reinforced concrete box culverts: the barrel itself, the fill carried over it, the soil it bears on and pushes against, the earth and live loads acting on it, and the AASHTO code checks and reports used to design it.

Work through the groups in order — define the culvert axis and structure, set up materials, rebars and the culvert section, place the barrel, then add the fill and soil-structure interaction, the loading and combinations, and finally the code check and reports.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openbrim.org/templates/box-culvert-workflow.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
