# Construction

### A5.2 Construction Activities

Enter a custom carbon intensity (kgCO₂e/sf) for emissions related to construction activities and land use. The default value assumes 40 kgCO₂e/m² for construction emissions, which includes fuel, tools, and energy used on-site. This default is adjustable based on project-specific data. For greenfield sites, emissions from soil and vegetation are also calculated, using regional data to estimate carbon release from land development.

### A5.1 Demolished Area

C.Scale calculates pre-construction demolition emissions per floor area of the demolished building, using a default of 35 kgCO₂e/m². This is a data-scarce category. Where project-specific data is available, you can override this default.

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.cscale.io/users-guide/reduce-emissions/carbon-reduction-measures/construction.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.
