Case Study: New Jersey Turnpike Widening – Design-Build Delivery and Scope Management Issues (2015)
Project Overview
• Name: New Jersey Turnpike Widening Project
• Location: New Jersey
• Year: 2015
• Project Size: $1.3 billion
• Scope: Widening of highway lanes and bridge rehabilitation using a Design-Build approach
• Lead Agencies/Contractors: New Jersey Turnpike Authority, Design-Build Contractor JV
Category of the Issue, Problem, or Challenge
• Project Delivery Method
• Design-Build
Summary of the Issue, Problem, or Challenge
During construction, scope creep and late-stage design changes led to significant cost increases and schedule delays. Contract terms lacked mechanisms for effective scope change control, leading to disputes and inefficient resource allocation.
Root Cause Analysis
- Insufficient early scope definition and freeze.
- Lack of formal change management procedures embedded in the contract.
- Poor coordination between design and construction teams on change impacts.
- Inadequate contingency planning for scope growth.
Impacts Due to the Issue, Problem, or Challenge
• Schedule delays totaling 6 months.
• Cost overruns of approximately $50 million.
• Increased claims and contentious contract negotiations.
Corrective Actions Taken
- Instituted formal change management and scope freeze protocols.
- Improved integration between design and construction disciplines for change assessment.
- Enhanced owner involvement in scope definition and approval.
- Increased contingency budgeting to accommodate unforeseen changes.
Lessons Learned
- Early and clear scope definition prevents costly scope creep.
- Formal change management systems are critical in Design-Build projects.
- Coordination among disciplines helps manage change impacts.
- Owner engagement throughout helps control scope growth.
Audit & Prevention: Project Control Questions to Ask on Future Projects to Help Control the Situation
- Is the project scope well defined and frozen early?
- Are change management procedures clearly defined?
- Is design-construction coordination effective for managing changes?
- Are contingency budgets sufficient and well managed?
