# Foundation Construction (Partial) \[CSB] ## Foundation Partial Construction If a footing is built in two connected stages, such as the first stage being associated with an existing structure constructed 20 years ago and the second stage involving the addition of a new part to the footing for a rehabilitation project, this object can be used to simulate the behavior. If the footings are not connected, two separate footings can be constructed in two different stages. **Stage:** Choose the stage for constructing the footings. **Foundation:** Choose the footings for construction. **Start Station (From Right):** When determining stations in the direction of PGL, starting from the right, specify the start station of the foundation to be constructed. **End Station (From Right):** When determining stations in the direction of PGL, starting from the right, specify the end station of the foundation to be constructed. **Self-Weight Factor**: The Self-Weight Factor is a parameter used to adjust the contribution of an object's own weight in structural analysis. This factor is particularly useful in simulations, as it enables the scaling or modification of the self-weight during finite element analysis (FEA). --- # Agent Instructions: 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: ``` GET https://docs.openbrim.org/templates/cable-stayed-bridge-workflow/construction-csb/substructure-construction-csb/foundation-construction-partial-csb.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
