Red and Blue Line Platform Extensions

Dallas Area Rapid Transit (DART) is a regional transit agency created by voters and funded with a one-cent local sales tax on August 13, 1983. Thirteen cities within a 700-square-mile area are served by DART’s buses, Trinity Railway Express, and Light
Rail (LRT) commuter rail systems. The LRT—the focus of this project—encompasses 93 miles of track and 64 stations.

To address the demands of increased ridership, DART initiated a new project to construct LRT station platform extensions of varying lengths and add special use platform areas in order to facilitate three-car train level-boarding at 28 existing stations. Currently these stations can only accommodate two-car trains. When work on the $149 million project is completed in 2021, DART estimates a 50 percent increase in capacity at the updated stations and a 12 percent increase in capacity along the corridor overall.

Schnabel was hired in 2016 to conduct a formal value engineering study and update the project risk register. To accomplish and inform the value engineering study, we led a five-day workshop with a ten-member multidisciplinary team from DART, Hill International, VAI and Solis/Hill. The team generated 71 different ideas which resulted in 12 final and fully developed recommendations for cost savings via design and construction efficiencies. We also managed the risk workshop effort, which involved development, evaluation and updating of the risk register, as well as preparation of a final risk status report which outlined DART’s risk exposure.
