Systems Integration on a Light Rail Project: A Tale of Two Agencies

摘要

Subject Track: Passenger & Transit As Transit Agencies progress to build new Light Rail Transit (LRT) Projects or extend existing Starter lines, one of the newer elements has been Interface Management or Design Integration between the Civil design and the Systems design. In the Seattle area, Sound Transit has incorporated some of the Design Integration processes utilized by the Aerospace Industry in the Puget Sound region as it extends the initial Central Link LRT line east to Bellevue and Redmond, WA. In Hawaii, the Honolulu Authority for Rapid Transit (HART) accomplishes the same integration of the Design/Build Systems contract elements into their Aerial Station Final Design construction contracts through an Interface Management approach. As the benefits of a Systems Integration or Design Interface approach become more widely known in the Rail Transit Industry, the pros and cons of how and when to use these tools in the various design and construction contracts becomes more apparent. Supporting the integration process, Sound Transit has been increasing the use of clash detection on the 3-D models for the stations in each stage of the design process. To document the design decisions or respond to design questions, Sound Transit uses a centralized ICD Database. Similarly, in Honolulu, HART utilizes an Interface Management approach with the progress on each design decision or direction tracked through a contract management system database. In summary, Interface Management/Design or Systems Integration may use different tools or have a different role depending on the type of the rail transit construction contract.
