# Bebo Precast Concrete Arch Bridge Template

The Bebo Precast Concrete Arch Bridge Template models a buried precast concrete arch structure: the precast arch units spanning between stem walls or abutments, the structural fill placed over and around them, and the roadway and barriers carried on top.

Work through the items in order — place the arch on its supporting stem walls, add the structural fill that carries the road over it, then define the roadway surface and its barriers.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.openbrim.org/templates/bebo-precast-arch-bridge-workflow.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
