Project Overview
Name: Missouri River Bridge Replacement
Location: Jefferson City, Missouri
Year: 2020
Project Size: $310 million
Scope: Demolition and replacement of aging river bridge infrastructure
Lead Agencies/Contractors: Missouri DOT (Owner) /


Category of the Issue, Problem, or Challenge
• Contract Owner
• Scope Management


Summary of the Issue, Problem, or Challenge
During construction, the Missouri DOT repeatedly expanded project requirements—including lane additions and design changes—without appropriate contract amendments. This led to out-of-sequence work and delays.


Root Cause Analysis

  • Owner-initiated scope changes mid-construction.
  • No formalized change control process.
  • Delayed decisions on design approvals.
  • Poor coordination between owner’s engineers and construction team.

Impacts Due to the Issue, Problem, or Challenge

  • Six-month project delay.
  • $21 million in added costs due to inefficiencies and rework.
  • Strained contractor-owner relationships and legal dispute over change orders.

Corrective Actions Taken

  1. Owner established formal scope change approval and tracking process.
  2. All design changes reviewed through a joint technical review board.
  3. Improved contractor involvement in early design revisions.

Lessons Learned

  • Scope creep must be managed through disciplined change control.
  • Construction-phase design changes should involve the delivery team.
  • Owner and contractor collaboration reduces risk of disruption.

Audit & Prevention: Project Control Questions to Ask on Future Projects to Help Control the Situation

  • Is a formal scope change procedure in place and followed?
  • Are construction-phase changes reviewed for impact before implementation?
  • Is there a structured coordination process between owner and contractor?
