# Construction

Constructing items is a fundamental part of expanding and optimizing your outpost in **Outpost Surge**. Using resources such as ore from mining and parts delivered by rocket missions, you can build various structures to support your operations and ensure survival on Mars.

***

### How to Construct Items

#### Accessing Constructible Items

* Use the **Library** to navigate available constructible items. Items are categorized based on their function, such as power generation, resource extraction, or astronaut support.
* Each item requires specific resources, which you can track in your resource overview.

#### Placing Items on the Map

1. **Select an Item**:
   * Tap on the desired item in the Library to begin placement.
2. **Position the Item**:
   * Move the item to the desired location on the map.
   * Rotate the item for better customization and optimal placement.
3. **Check Placement Validity**:
   * The item’s footprint will appear **green** if the location is valid.
   * If the footprint is **red**, placement is blocked due to another building or an immovable terrain feature.
4. **Confirm Placement**:
   * Once you’ve positioned the item in a valid location, confirm the placement to begin construction.

### Tips for Effective Construction

1. **Plan Ahead**:
   * Ensure the placement of buildings supports efficient resource flow and accessibility.
   * Avoid overcrowding areas, which can hinder future expansion.
2. **Utilize Rotation**:
   * Rotate items to fit irregular spaces or optimize their functionality within your layout.
3. **Verify Resources**:
   * Check that you have enough ore and parts before initiating construction.
   * Plan rocket missions to deliver parts needed for high-priority structures.
4. **Adapt to Terrain**:
   * Use the map to identify flat, open areas for large structures.
   * Work around immovable terrain features to maximize available space.

Constructing items strategically will allow you to build a thriving and efficient outpost, ensuring the survival and growth of your operations on Mars. Good luck, Commander!
