# Barrier \[RW]

The Barrier object models a standard-plan barrier carried on the haunch seat at the top of a retaining wall segment. It is distinct from the bridge barrier: it is hosted by a wall segment rather than a deck, and follows the segment's alignment and top-of-wall profile.

## General

**Segment:** The wall segment that carries the barrier. The barrier follows the alignment and top-of-wall elevation of the selected segment.

**Barrier Section (Standard Plan):** Cross-section of the barrier, selected from the standard-plan barrier sections.

**Batter Side \[Left=1/Right=2]:** Side the barrier face is battered toward. By default this follows the stem orientation of the host segment.

**Start Offset:** Longitudinal offset of the barrier start from the start of the host segment (default: 0).

**End Offset:** Longitudinal offset of the barrier end from the end of the host segment (default: 0).

**Transverse Offset (onto haunch seat):** Transverse position of the barrier on the haunch seat at the top of the wall (default: 0).

**Barrier Material:** Material assigned to the barrier.

## FEA

**Generate FEM \[NO=0/YES=1]:** Setting this to NO disables the analytical (finite-element) representation of the barrier (default: YES=1).

## Quantities

**Total Volume:** Concrete volume of the barrier. (Read-only)

**Total Weight:** Concrete weight of the barrier. (Read-only)

**Material:** Material reported for the barrier in quantity take-offs. (Read-only)

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 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/retaining-wall-workflow/retaining-wall-rw/barrier-rw.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.
