# Superstructure Construction

This section defines the construction sequence for all superstructure components.

## Overview

Steel girder erection and deck pouring sequence is a critical process in the construction of a steel bridge:

* Steel girders are erected and braced
* Deck formwork is placed on girders
* Concrete deck is poured in stages
* Each pour stage is followed by a stiffness gain stage when concrete hardens

OpenBrIM platform offers the capability to model all stages involved in steel bridge construction, including deck construction, complete girder erection for design purposes, and partial girder erection and temporary support construction for the erection process.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/examples/steel-bridge-examples/example-steel-tub-girder-bridge-ex1-stg/construction-ex1-stg/superstructure-construction-ex1-stg.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.
