Option 5‐1 Hybrid ‐ Charrette

Charrette Direction
12
• Option 1 should be carried forward
• Option 2 wasted too much backlands and should be dropped
• Options 3 and 4 were dropped for several reasons:
• Pushing further offshore is outside the permit area
• Pushing further offshore creates more challenges for vessel
approach and mooring
• Pushing further offshore exacerbates shoaling at Terminal 3
• Option 5 should be carried forward (popular with carriers)
• Option 5 – 1 Hybrid should be developed further

Cost and Schedule Risk Assessment
39
• Typical deterministic method estimates costs then adds contingency (e.g. 20%)
• Benefits of the CSRA– Identifies high risk items to cost and schedule
– Provides leadership contingency information for scheduling and budgeting
– Allows management of risks through a formal process throughout the design process.
– Provides a proven structure for communicating project costs with stakeholders.
