# accesslevelvalue

This code list is used in association with the Access Level attribute which is present within the Building Access Location Feature Type. The code list provides an indicator of the relative location of the access point with respect to ground level.

| Above Surface Level | Access to the building is at least one floor above the normal surface level, such as up steps, or a via a bridge from another building.                                                                                                                                       |
| Below Surface Level | Access to the building is at least one floor below the normal surface level, such as down steps, down a ramp or underground.                                                                                                                                                  |
| Surface Level       | Access to the building is at ground level and doesn’t require more than one floor level’s ascent or descent from ground level. Note that this has a subtly different meaning to the physicalLevel of ‘Surface Level’ applied to Building Part and other topographic features. |

# 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.os.uk/osngd/code-lists/code-lists-overview/accesslevelvalue.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.
