Results

Why do Cost Based Estimating? Provides the highest quality estimate possible. Red flags possible quantity errors, unworkable

staging, plan and contract errors and discrepancies.

Best benchmark possible. Guarantees fewer projects outside awardable

ranges. Credibility and confidence for upper management

decision making. Forms the foundation for bid collusion detection.
