Bechtel Project Review

• Major Questions Addressed
• Is Caltrans cost estimating methodology
  reasonable?
• What options are available to reduce project
  costs?

Bechtels Project Review Findings

• Cost estimating methodology appears reasonable.
• Terminating and re-bidding remaining work would
  not be cost effective and would be more risky.
• Negotiating a fixed price contract adjustment for
  remaining work is best approach.
