Scenario: You are a civil engineer working on a new bridge construction project. You need to establish a datum for the project to ensure accurate measurements and consistent construction.
Task: 1. Identify a suitable datum for the bridge construction project. 2. Explain your reasoning for choosing this specific datum. 3. Describe at least two ways this datum will be used throughout the project.
**Suitable Datum:** A common datum for bridge construction projects is the **Mean Sea Level (MSL)**.
**Reasoning:** MSL is a widely accepted datum, it is easily accessible and serves as a consistent reference point for elevation measurements. It is also a stable reference point that is not affected by local variations in ground elevation.
**Uses in the project:**
