Scenario Planner for Construction

Scenario Planner for Construction

Overview

Model different project scenarios to understand their impacts on cost, schedule, and resources. Compare alternatives, optimize decisions, and prepare for contingencies.

Business Case

Construction decisions require understanding trade-offs:

• Design Alternatives: Which option is most cost-effective?
• Schedule Compression: What's the cost of accelerating?
• Resource Options: In-house vs. subcontractor?
• Risk Scenarios: What if materials increase 20%?
