The I-3 segment of the Orange Line extension was awarded to Parsons and its JV in December 2011. This extension will take the Orange Line from the DFW property edge directly to the DFW Terminal A, completing the link between downtown Dallas and this major international airport. Again, our team aggressively developed a unique alignment that reduced bridge structure while avoiding a right-of-way conflict with future Texas Department of Transportation (DOT) project development. This win-win solution was well received and demonstrated our team’s ability to provide unique solutions to complex transportation problems.
As lead designer for the JV, Parsons self-performed about half of the overall design work and managed the large contingent of disadvantaged business enterprise (DBE) and minority- and women-owned business enterprise (MWBE) subconsultants required to fulfill DART’s goal of 40% DBE/MWBE participation.
Safety and Sustainability Are Important
This project uses the JV’s safety program—guided by our commitment to zero incidents—and has a better safety record than any other current construction project in the DART network:
- The office safety plan complies with START/SHARP, and the staff has been trained in office safety protocol.
- All staff must take a DART safety training program.
- All construction staff attend onsite training.
- Personal protective equipment (PPE) is issued to all employees.
- Subcontractor oversight includes incentive programs.
The DART Orange Line extension is yet another of our contributions to a sustainable transportation system. By extending the existing light rail system in the Dallas area through Irving all the way to DFW, this project reduces reliance on automobile travel for another segment of the region’s population—reducing carbon emissions—and paves the way to a cleaner, greener future for this bustling metropolitan area.
In addition to the environmental benefits inherent to a light rail system, Parsons, with its JV partner, used a joint document control system that drastically reduced the amount of paper used. Sustainability, however, involves more than decreasing the impact on the environment. It also emphasizes minimizing the impact on the community. Using several alternative technical concepts, Parsons saved DART $80 million, achieving both environmental benefits and economic sustainability.
