Taking a Public Private Partnership (P3) approach, NCDOT contracted I-77 Mobility Partners to manage the addition of multiple variable rate toll lanes along 26-miles of the I-77 corridor servicing the Charlotte metro area. As technical advisor to I-77 Mobility Partners, Kleinfelder provided quality oversight through inspection, sampling and testing of construction materials, observations, and documentation of progress.

Asphalt Pavement Quality Critical to Success

As a high-profile project that was highly scrutinized by residents and stakeholders, maintaining proper compliance and quality was crucial to the project’s success. I-77 Mobility Partners identified asphalt pavement quality as a primary concern that could impact success.

Minimizing Non-Conformances and Inefficiencies

Kleinfelder’s approach to managing quality and risk involved minimizing repeat non-conformances and inefficiencies. In addition to reporting non- conformities to the client, Kleinfelder worked with the Design-Build JV to perform root cause analyses and develop solutions to address the root cause, such as implementing alternative methods to perform the work or training staff on proper procedures. Kleinfelder then verified and validated the implemented solutions. We also bolstered our quality oversight by bringing  in additional staff from other offices with extensive asphalt and roadway construction experience.

Project Results

As technical advisor, Kleinfelder worked with the Design-Build JV to perform root cause analyses and develop solutions for non-conformities, such as implementing alternative methods to perform the work or training staff on proper procedures. During the peak of construction, Kleinfelder maintained a 24-hour presence for a period of 7 months.
