2. Which excavation method uses a slurry-filled trench to maintain stability while installing a concrete diaphragm wall?

4. Why is risk management important in construction contracts?
To identify and mitigate potential risks

Risk management is crucial in construction contracts because it involves systematically identifying, assessing, and developing strategies to mitigate potential risks that could impact the project. By clearly allocating responsibilities for various risks within the contract, parties can proactively plan for uncertainties like cost overruns, delays, or unforeseen site conditions. This minimizes disputes, protects financial interests, and contributes to a more predictable project outcome.
