# Pier Cap/Bent Construction (Complete)

This section defines the pier cap construction stage.

## Overview

The design process of steel girder bridges typically involves modeling the construction of pier caps, pier columns, foundations, and piles as a single stage to streamline the analysis and reduce the number of required stages. However, in real-world construction, these components may be constructed separately over multiple stages, depending on factors such as site conditions, available resources, and project schedule. OpenBrIM offers features that allow users to model these details with various stages and time-dependent staged construction analysis.

## Steps

### Step 1: Navigate to Pier Cap Construction

Navigate to **Loading > Construction > Substructure > Pier Cap/End Bent (Complete)** in the tree view.

## 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/examples/steel-bridge-examples/example-steel-tub-girder-bridge-ex1-stg/construction-ex1-stg/substructure-construction-ex1-stg/pier-capbent-construction-complete-ex1-stg.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.
